IDOL SPAS Hot Tub Instruction Manual
this document provides useful information about the preparation and operation of your new hot tub.
CONTENTS OF THE DOCUMENT
This user manual and its contents may change without any prior notification. Although IDOL SPAS has prepared this Instruction Manual as precisely and correctly as possible, IDOL SPAS shall bear no liability for any losses, impairments and damages caused by improper maintenance or use of the hot tub (incorrectly or otherwise).
IDOL SPAS hot tubs can be installed both indoors and outdoors.
When installed outdoors, we strongly recommend using full insulation and a thermal cover. The full insulation and the thermal cover keep the water temperature and thus save you money. Covering the hot tub with the thermal cover when you are not using it prevents contamination of the water.
The full insulation and the thermal cover can also be used when the hot tub is installed indoors. The full insulation prevents fast cooling of the water and the thermal cover keeps humidity in the tub and prevents it from spreading into the room when the tub is not actively used.
When choosing from our warehouse stock, you can find the optional equipment available for each type of hot tub as it is demanded by most customers.
When installing the hot tub indoors, pay attention to the surface onto which it will be positioned. Select a surface that is not damaged or contaminated. The interior must be ventilated due to humidity spreading into the room from the hot tub during its active use. At the least, provide windows that can be opened and cover the tub with the thermal cover when not in use to prevent humidity from spreading.
Your hot tub requires a solid and level foundation. The place where the tub is to be installed must bear the weight of the tub with water and people. If the foundation is unsuitable, the tub may shift or subside when installed, which may damage it.
Concrete foundation is the best (5 – 8cm thick). Consult any other foundation with the seller/experts. Consider the bearing capacity of up to 500kg/m2 according to the size of the tub. Consult the bearing capacity of elevated constructions with a structural engineer. We recommend having the foundation plate for your hot tub built by a qualified and licenced company.
Where to Install a Hot Tub?
Determine the position of the hot tub according to the planned method of use. For example, will you use the hot tub for recreational or therapeutic purposes? If used predominantly for family recreation, make sure that there is enough space for other activities. If used mainly for relaxation and hydrotherapy, you will probably want to create a special atmosphere in the room.
If you live in a cool or rainy region, install the hot tub close to the house entrance so that you can change comfortably and warmly.
You should also think about what you want to see when you are sitting in the hot tub. Do you have a favourite spot on your property? Or it could be a place with a pleasant breeze or with the view of an enchanting sunset in the evening.
Attention! An additional space of 50 – 60cm on each side of the hot tub is required for maintenance to allow a technician to access all technologies. When in use, the hot tub can be by the wall.
All our hot tubs are suitable for embedding in the floor. They can be embedded partially or completely (up to the acrylate). The foundation must be reinforced! Concrete is the best solution. Consult its thickness with the seller/experts. Once again, the surface must be level.
Attention! When embedding the hot tub, an additional space of 50 – 60cm on each side of the tub is required for maintenance to allow a technician to access all technologies. The most important side to be accessed is the side with the control panel. If you decide to embed the hot tub, consult it with the seller so that you are properly prepared!
STRUCTURAL READINESS FOR EMBEDDING THE HOT TUB IN CASE OF A LACK OF SPACE
The technician needs enough space for potential service
Recommended electrical readiness for the connection and installation of the standard IDOL SPAS hot tub:
Simply said: 400V 5C x 4mm, three-phase circuit breaker 20A – 25A, characteristics “C” or “D”. It is possible to use a cable with the core cross-section of 2.5mm and 16A circuit breaker, characteristics “C” or “D” for some of the smaller hot tubs after consultation with an IDOL SPAS technician. All devices in the hot tub are single-phase.
All hot tubs require a permanent independent IGA circuit with current protection In=0.03A with no other devices connected! Make sure that the cable on the output from the electrical system of the hot tub is long enough so that it can be directly connected to the power supply. If you do not know the exact distance, leave the cable at least 5m long at the connection.
If it is not possible to use a three-phase connection to 400V, an individual consultation with a IDOL SPAS technician is required due to protection. All technologies in the hot tubs are single-phase and they can be connected to two phases, or a single phase.
Only the Lite 230 Series. The hot tubs are equipped with a cable with a regular 230V plug and current protection.
They can be connected to a regular single-phase socket. However, the hot tub must be connected on an independent circuit with 16A circuit breaker, characteristics C.
Only a professional can install and connect the hot tub to the power supply! We can provide customers with an option to execute the connection on their own but then the customer bears liability for any potential consequences of a bad connection. We always recommend a professional firm, an electrician.
Attention! Only a professional can install and connect the hot tub to the power supply! Always consult the seller.
Hot tubs are not connected to water supply. Using a garden hose is ideal for filling up your hot tub. Fill it up to the line. Try to keep the line as much as possible as it is important for the proper functionality of all technologies.
Each hot tub has an outlet valve; you can either empty it in the garden, or into the sewer. When emptying the tub in the garden, pay attention to its gradient (to avoid getting wet, or flooding your neighbour’s vegetable plot).
You can use an outlet valve attached to a hose to empty the hot tub into the garden/sewer. The water in the hot tub is replaced about 2 to 3 times a year. Some people change it more often, other people less often. It is up to the user to decide when to change the water, in addition to using chemicals properly.
Check that the overflow discharge valve (if the hot tub is equipped with one) is fully open and the plug is unscrewed.
- When the temperature is around 0°C and less, it is important that the hot tub is always connected to the power supply and is running. Otherwise, the hot tub can freeze and subsequently get damaged; such damage is not covered by the warranty.
- An empty hot tub must be placed in an area with ambient temperature above 5°C to prevent any remaining water in the distribution system of the hot tub from freezing.
- When the hot tub is installed indoors, check that the room is ventilated when using the ozone cleaning.
- Before filling up the hot tub for the first time, check that the cartridges are not in the protective film. If so, remove it. When filling and running the hot tub for the first time, do not use the cartridges – place the cartridges in water outside the skimmer for 30 minutes before placing them in the hot tub to let the filters absorb water (this prevents air intake of the filter pump).
- Keep the cartridge filters clean. Change them at least once a year and rinse them with clean water at least once every 14 days (with a garden hose or disinfection bath specially designed for this purpose).
- If the display shows EP after the circulation pump/heating has been turned on, the hot tub will switch to an emergency mode to prevent damage to the heating. To reset this message, remove the cartridge filters and press the heating button.
WARNING: The hot tub is equipped with massage pumps that allow jets to work independently or at the same time. Do not connect an empty hot tub to the power supply as the equipment, such as control, heating, water-jet pump and other devices can get damaged!!!
The temperature of the water in the hot tub must not exceed 40°C. Temperature between 38°C and 40°C is considered safe for a healthy adult person, however, only for a very short time in the hot tub. Temperature above 40°C for a prolonged period of time is dangerous for the technology. An optimal temperature for a long-term use of the hot tub is the body temperature and below, i.e. 36.5°C and below.
If you spend more than 15 minutes in the water (it is very individual), you can experience symptoms of organism overheating – dizziness and headache, weariness, nausea… If any of these symptoms occur, you should either leave the hot tub, or rest on the elevated seat where the top part of your body can cool down, which will make you feel better.
It is important to pay special attention to children who do not tolerate hot water as well as adults. We also recommend body temperature and below.
It is harmful to health to repeatedly spend prolonged time in temperatures higher than body temperature!
If you have not had an automatic dispenser of chemicals or bromide salt installed in your hot tub, it is necessary to keep the correct chemical composition of the water so that it does not go bad and does not show signs of contamination. The rule is that whatever falls into the hot tub, stays in the hot tub.
The water used for hot tubs is usually not suitable for hot tubs without any treatment. Whether you use water from the hydrant, a regular water pipeline or from a well, the water has to be treated as soon as possible. Some customers believe that if they only use the hot tub five times a month, it is better to fill the hot tub up and then empty it. With regard to the unsuitable water composition, such a solution is not ideal for the hot tub in the long term. Without the chemicals that clean all the pipes in the hot tub, stuff such as skin, oil, or hair – biofilm accumulate in the hot tub.
The chemical composition of water in the hot tub constantly changes, even after the first treatment. That is mainly caused by changes in temperature, natural effects and also by us and the frequency of use. The cartridge filter and the ozone device, included in each hot tub, are not enough to clean the water.
It is fundamental to keep the correct pH level
Keeping the correct pH level is important for healthy water in the hot tub suitable both for us and for the technology. We should check pH before and after the application of chemicals. When the pH is not correct, the chemical preparations might react contrary to our expectations.
The pH value should be around 7. It is okay when the pH value ranges from 6.9 to 7.5.
When pH is too low, the metal parts start to corrode and the colours, plastic materials and films start to fade and degrade. When pH is too high, minerals from water start to separate and it becomes cloudy. Plastic materials start to degrade. The air surrounding the pool may have increased concentration of chemicals.
Water pH slowly changes according to the local composition and hardness during regular use; pH of soft water decreases and pH of hard water increases. The correct pH value is easily adjusted using the pH plus or pH minus preparation with the filter device turned on in order to provide the required water circulation. We use the three following preparations that are essential:
- pH tester – with a pH value indicator
- pH+ – a preparation for adjusting pH in water
- pH- – a preparation for adjusting pH in water
Explaining Terms: pH, Water Acidity and Alkalinity
pH – Measuring pH of liquid determines whether the liquid is acidic or alkaline, on a pH scale that starts with 0 on the acidic side and goes up to 14 on the alkaline side. The concentration of H+ and OH- ions is balanced when pH of water is 7. Substances with pH value below 7 are acidic as they contain higher concentrations of H+ ions. Substances with pH value above 7 are alkaline as they contain higher concentration of OH- ions than H+ ions. The pH scale is logarithmic and thus a unit change in the pH value means a tenfold change in the concentration of hydrogen ions.
The pH value is determined using various types of testers and adjusted using pH+ and pH- preparations, or by installing automatic pH dispensers into the hot tub.
We can choose either chlorine chemistry, or chlorine-free chemistry (i.e. active oxygen) for regular water maintenance. The basic chemistry is used about once a week.
It is a time-tested method of water disinfection that kills everything you do not want in the water. There is no need to worry about harmfulness when using quality preparations. It is important to follow the time intervals between the application of the chemicals and bathing, which is usually two hours. When this time passes, the chemical preparation is no longer as concentrated and we can bathe without any worries.
Watch out for Unintended Over-chlorination
When the water in the hot tub is chlorinated too much, which can easily happen with the small quantity and hot water, it is not suitable to bathe in such water (eye irritation, rash, damaged swimming clothes…), but also, the equipment of the hot tub can get damaged.
When the water is chlorinated too much, you can smell the chlorine – it is an unpleasant odour which is aggressive to skin and mucous membranes, chlorine quickly evaporates into the air and it is difficult to breathe. The first aid usually includes ventilation of the area where the hot tub is installed and diluting the water in the hot tub.
It is absolutely inappropriate to close the hot tub and expect that the chlorine will disappear. It will disappear eventually, but it will damage all the stainless and plastic parts of the hot tub above the water surface and also the thermal cover. Faded headrests in the hot tub and the thermal cover are the first consequence and indicator of over-chlorinated water in the hot tub, which further disintegrates, cracks and crumbles.
The water in the hot tub can be over-chlorinated on purpose in the so-called “shock” treatment of the water. This means that a high content of chlorine is added to the water to disinfect the hot tub. The water is saved but the evaporating chlorine has to be properly aired out. This intended over-chlorination is mainly used when people use swimming clothes in the tub that release phosphates from laundry detergents into the water, or when people do not rinse off properly before bathing in the tub.
The water is then contaminated with residues of cosmetic substances from cosmetic preparations, oils and other material. Or, the water in the hot tub goes bad because we forgot to treat it.
NON-CHLORINE CHEMICALS (ACTIVE OXYGEN)
An alternative water treatment without the use of standard chlorine.
The treatment of water in the hot tub with active oxygen required the use of two products at the same time: tablet/powder of active oxygen + activator. You can choose from the following:
- SPA OXY (tablets) + SPAaOXY (activator)
- GUAa OXI (powder) + GUAa (activator that can be used separately)
In both cases, mix the preparations according to the instructions on the label on the back side in a vessel outside the hot tub. As soon as the tablet/powder dissolves in the activator, pour the mixture into the water.
If the hot tub is actively used, we recommend using the GUAa preparation in the meantime. For example: when applying active oxygen once a week, use GUAa on the third day. This will ensure clear water that looks clean at first sight.
To maintain pH and as an addition to both versions of basic chemicals, other chemical preparations for water maintenance are combined. From the Just Relax series:
Clarification – Flocculating agent. Preparation for removing cloudiness and organic substances
Decalcit – Preparation for immediate removal of calcic sediments
Antifoam – Preparation for immediate removal of foam
Whirlpool pure – Preparation for complete cleaning of the hot tub before emptying. The water is no longer suitable for bathing after its application! After the application, turn on all the pumps and let the preparation get thoroughly mixed with water to access all the hoses in order to clean them. Empty the water and fill the tub with fresh water.
Automatic Chemicals Dispenser
The hot tub can be equipped with one of the automatic chemical dispensers to save time and work with water maintenance, such as:
- pH automatics
- pH + chlorine automatics
- pH + non-chlorine automatics
Contact us or suppliers of the technologies to learn about the possibilities and conditions of installation of an automatic chemical dispenser.
If the hot tub does not have any of the automatic dispensers, use chemicals according to the instructions on back labels.
The high content of minerals dissolved in water, or hard water, affects all the equipment that comes into contact with such water, and that includes the hot tub. The jets are slowly clogged or the heater becomes covered so when hard water is not checked and treated, the appliance is put out of operation and needs service. As a preventive measure, use a suitable softening preparation to treat the water before the first filling and each time you refill the tub. When the water is good, it should not be often changed or refilled. It is recommended to run the jets more often to prevent clogging.
Impurities that get into the hot tub end in the cartridge filter, or a sand filter thanks to the water circulation. The filter in the hot tub is an oasis for bacteria. A contaminated filter also prevents the proper flow of water and can lead to a pump failure.
Cartridge filter – private use, smaller family, smaller hot tub
Sand filtration – commercial use, or a larger family, larger hot tub
There are many types of the standard cartridge filter. The cartridges are with or without thread and they come in various widths and heights. The filter has to be checked regularly and kept clean. A new filter is white, an old and worn filter is grey/grey yellow. For filter maintenance, we can use a strong water flow of the garden hose, a dishwasher (without any other dishes and without the use of the dishwasher tablet or detergent), or we can use the CleanFilter chemical bath which is best for removing oils from the filter. We recommend rinsing the filter once every 14 days and doing the chemical bath at least once every 3 months. The cartridges are sufficient for large hot tubs as long as the filter is well taken care of.
Old and new cartridge filter
- Once every two weeks, we should rinse the filter thoroughly and remove impurities such as skin, hair etc. At least once every three months, the filter has to be cleaned with the use of a special preparation to remove oil that is the worst contaminant for the filter and aggravates the flow of water through the filter.
- Soak the filter in a vessel with hot water over the night. To thoroughly clean (degrease) the cartridge filter, add the preparation mentioned above.
- After soaking the filter over the night, rinse it thoroughly in clean water. The cleaning agent absorbed inside the filter could contaminate the water, which could, at worst, be dangerous to people.
When it is no longer possible to clean the cartridge filter, simply replace it with a new one. The hygienic frequency of replacing the filter should be about once a year on average. You can order cartridge filters for all hot tubs from us. We always recommend that our customers keep a spare clean filter so that the hot tub does not stay without a filter during cleaning.
If a larger load on the filtration is expected (e.g. a larger family, children…), we recommend installing sand filtration to the hot tub. It can absorb much more contamination than the cartridge filter and guarantees clean water with a lower maintenance frequency. Sand filtration is required by law when hot tubs are used in wellness studios, guesthouses, hotels… There are also other obligations of the owner that the customer needs to be informed of if he or she is planning to use the hot tub commercially.
- Rinse with clean water before entering the hot tub. Pay attention to any soap and shampoo residue.
- Do not use sunscreens, including water-resistant ones, in the summer!
- Place a small tub with water to the hot tub for cleaning your feet before entering the hot tub, to remove the largest impurities – grass, sand, soil etc. – stuck to your feet.
- Use a hair band to keep your hair together.
- Remove any make-up before entering the hot tub.
Following those simple rules will simplify the maintenance of clean water.
You should check the water composition values after bathing for any changes. The disinfectant naturally evaporates from water and stops acting after a while. Also, it is consumed with impurities that must be removed from the water and thus its content can be reduced after a relatively short time, depending on the load and contamination of the water. A simple and practical trick for maintaining water and chemicals at a normal level is to follow the principle of adding a bit of chemicals after each longer bathing, particularly when there are a lot of people.
The thermal cover should be used for every hot tub. Almost 90% of heat escapes water through its surface. You can significantly limit such loss by using the thermal cover and thus keep water warm even when the weather is very cold. We recommend using the cover together with insulation both outside and inside. The customer saves in both cases as the water in the hot tub is warm longer. The steam from the water rises up. The thermal cover works in the same way as a lid on a saucepan – it returns steam into liquid state and maintains the water temperature. The thermal cover protects the hot tub from gross impurities, such as leaves, needles, pollen, insect, rain, snow etc. Such impurities put an excessive load on the filter which causes its excessive wear and tear. By using the cover in the interior, you prevent contamination of the water with dust but you also prevent humidity and steam condensation. The thermal cover also increases safety of your hot tub, which is particularly appreciated by customers with children.
The thermal cover is made individually for each hot tub and it has a skirt that also covers the acrylate on the sides. The thermal cover creates pressure thanks to which it adheres as well as a lid on the pressure cooker.
Thermal Cover Cross-section
1) Imitation leather cover
2) Aluminium profile
3) Sealing liner
6) Polystyrene insulation liner
7) Plastic film
8) Drain hole
9) Covering skirt
10) Fastening strap
11) Plastic buckle
The thermal cover is made to order for IDOL SPAS hot tubs according to a drawing attached to the order; for other hot tubs, it is delivered in the colour of the casing, unless you made a different choice prior to placing the order.
Only quality and verified materials are used for the production of the thermal cover. That provides excellent insulation properties. Our thermal covers excel in craftsmanship. The imitation leather is frost-resistant and UV-resistant when properly maintained, the insulating shaped pieces are made from quality polystyrene sealed in a plastic film and reinforced with aluminium “U” profiles that provide the thermal covers with the required strength and that are rust-resistant.
The thermal cover is made in the shape of a roof so water does not collect on it, but flows down freely.
Handling the thermal cover so that it does not get damaged is a matter of logic and instructions that you need to know and observe. Never walk on the thermal cover, it is not built for load. When there is a lot of snow, remove the snow from the thermal cover – its bearing part is polystyrene that could break under the weight of the snow. When handling the thermal cover, be careful so that it does not get pierced or torn. When pierced on the bottom, the thermal cover can absorb water and become heavy. The only solution then is replacement. Protect the thermal cover from excess effect of chlorine.
The hot tub can be used both in summer and in winter. Some customers like to use their hot tubs preferably in winter. The water warms you up nicely and relaxes you. The atmosphere is very different to summer.
There are advantages and disadvantages of emptying the hot tub for winter. Emptying the hot tub for winter saves you money for electricity but winter is the season when most hot tubs get damaged. It is caused either by insufficient protection from frost, however, when the temperatures are below zero for a long period of time, even the best protection from frost fails. There is always a bit of water left in the hoses. And it is the residual water after emptying that can cause much bigger damage than any savings made by emptying the hot tub are.
We Do Not Recommend Emptying the Hot Tub in Winter
If you are not planning to use the hot tub in winter and it is installed outside or in areas that are not heated, we recommend the following:
- Set half the regime for chemical batching (if chemical batching was insufficient, increase the batch at your discretion).
- Set the power-save mode on the control panel according to the instructions (set water heating to 5 hours a day at the lowest temperature (depends on the type of tub, usually 15°C).
- Set circulation and heating to at least 5 hours a day.
We recommend setting the heating and ozone disinfection with the internal of 12 hours (e.g.: if you set heating at 12:00, we recommend setting filtration to 24:00).
When the hot tub is installed outside and ambient temperature may drop below 0°C, we recommend turning on the circulation pump for 24 hours daily.
An emptied hot tub must be placed in an area where the ambient temperature exceeds 5°C to prevent residual water in the distribution system of the tub from freezing.
The warranty does not cover any damage of the hot tub caused by frost (not even in case of professional protection from frost).
Risk of Injury and Drowning
The suction equipment of the hot tub is designed for the specific values of water flow created by the pump. If you need to replace the suction equipment or the pump, make sure that they are compatible.
Never operate the hot tub when the suction equipment or the filter is damaged, or missing. Never replace the suction parts with incompatible parts (with different flow values).
Children are not allowed to use the hot tub or move in its vicinity without adult supervision. When not using the hot tub, cover it and secure the cover.
Be careful when entering and leaving the hot tub. You can get hurt by slipping on the wet surface.
Do not use alcohol and drugs before and during the use of the hot tub. It can lead to unconsciousness and drowning.
Do not use the hot tub after a hard work-out.
A long bath in the hot tub can be dangerous for your health.
Use chemicals for hot tubs according to the manufacturer’s instructions.
People with infectious disease cannot use the hot tub.
Electrical Shock Hazard
Do not install your hot tub under an overhead power line (minimum distance is 3 meters).
Install the hot tub at least 1.5m away from any metal surfaces.
No electrical appliances (lighting, telephones, radios, televisions etc.) can be near the hot tub (the minimum prescribed distance is 1.5m). Never let anyone use any electrical appliances inside the hot tub.
Connection is executed by experts!
Not for Pets
The hot tub is not a suitable place of cleaning your pets. The stay in the hot tub can cause stress, health issues, injury, drowning. Also, animal hair can clog the filter.
WARNING – Reduce the Injury Hazard
The high temperature of water may cause issues during pregnancy. Pregnant women should consult the use of a hot tub with their physician.
Consumption of alcohol or drugs before or during the bath can lead to unconsciousness and drowning.
People using pharmaceuticals should consult the possibility to use the hot tub with their physician.
People suffering from obesity, heart defects, or high or low blood pressure should consult the use of the hot tub with their physician.
Check that the surroundings of the hot tub are secured against water collection that could cause slipping and a potential injury.
A long-term exposure to hot air or water can cause hyperthermia. Hyperthermia happens when the internal body temperature rises by 2 or 4 degrees above normal temperature (37°C). Even though a short-term hyperthermia has health benefits, it is important to make sure that the body temperature does not exceed 39.5°C.
The symptoms of excessive hyperthermia are vertigo, lethargy, sleepiness and fainting. Excessive hyperthermia may cause:
- Failure to notice temperature
- Inability to recognize when it is necessary to leave the hot tub
- Inability to be aware of the imminent risk
- Damage to the foetus in pregnant women
- Physical inability to leave the hot tub
- Consumption of alcohol, drugs or some pharmaceuticals significantly increases the risk of hyperthermia
- Dirty filters. Clean filters with a stream of water, with a preparation, or purchase new filters.
- Microorganisms are formed in the water. Set the correct pH value, use the flocculating agent.
- Used water. Change water in the hot tub.
- Improper use of chemicals. Use chemicals only when the filtration cycle is used.
- Short filtration cycle. The filtration cycle when applying chemicals must be sufficiently long to allow the chemicals to thoroughly mix in the water and get everywhere. Sometimes, two hours of filtration are enough, at other times longer filtration is required, e.g. more frequent use, dirty water.
- Dirty filters. See Dirty Water.
- The pH value is low. Set the correct pH value using the tester and pH+.
- Insufficient hygiene. Thoroughly remove make-up before bathing. Thoroughly rinse soap. Do not use any lotions before entering the hot tub. Clean the filter, use antifoam, dilute water, and use disinfection.
- Application of unsuitable disinfection. Use antifoam, or dilute water with clean water, or replace it completely.
- Too much fragrant essence. Use according to the instructions on the back label. Use antifoam.
- Dirty filter. See Dirty Water.
- Water is too hard. Check and balance pH regularly! When too high, use pH-.
- Other possible causes: filtration cycles or water quality.
- Replace water if problems persist. Before emptying, thoroughly clean the pipeline using a suitable preparation.
- Too many organic substances in the water. Use suitable disinfection.
- Insufficient disinfection. Add more disinfectant.
- Incorrect pH value. Set the correct pH value using the tester and then set the correct pH using pH+ and pH- according to the determined values.
- The chlorine level is too high. Air out the water, dilute the water.
- The pH value is too low. Set the correct pH value using the tester and pH+.
- Bacteria and algae propagation. Disinfect or replace the water, thoroughly clean the pipeline using a suitable preparation.
Organic Sediments/Water Line
- Insufficient hygiene.
- Dirty filter. See Dirty Water.
- Oil contamination sediments. Wipe off the dirt, disinfect. Or replace the water.
- High pH value and low level of disinfection. Disinfect, balance pH.
- Low pH value and low level of disinfection. Set the pH value, disinfect.
- Water is not disinfected, chlorine content is over 5ppm. Disinfect and set the chlorine content below 5ppm.
- The pH value is low. Set the correct pH value using the tester and pH+.
Hot Tub Is Not Working
- Power supply is irregular, GFCI heating defect, thermostat error. Check the power supply, turn on GFCI again, if it does not start, contact the service. Disconnect from the power supply at least for 30 seconds. If not running again, check filters for clogging. If the defect continues, contact service.
Hot Tub Does Not Heat up but Jets and Lights Are Working (Voltage Indicators Are Flashing)
- Built-in pressure switch, open the circulation pump. Check filter tanks. The built-in pressure switch will start when circulation through the heating is restored. If the heating is still blocked, call the service. Check filter tanks. Disconnect the hot tub from the power supply and let the circulation pump cool down. Contact the service if the defect of the circulation pump continues.
Hot Tub Overheats
- If the hot tub overheats in spite of turning off the heating, we should reduce the circulation time or consider the place of installation of the hot tub (direct sun most of the day + concrete foundation may overheat the hot tub).
Voltage Indicator Is Flashing
- The thermostat for heating is defective. Disconnect the hot tub from the power supply at least for 30 seconds. If the defect continues, check filters for clogging, contact service.
- Temperature sensor error. Disconnect from the power supply for 30 seconds. If flashing continues, contact service.
Jets Are Weak
- The water level is low. Add water.
- Dirty filter. See Dirty Water.
- Air control closed, jets closed. Open air control. Open jets.
- Hr – Internal hardware error.
- Prr – Regulation sensor error. The system keeps checking whether the temperature sensor shows values in the set range.
- HL – Water temperature has reached 48°C. Do not enter the hot tub!
- FLO – System did not detect water flow even though the pump was running.
- UPL – Low-level configuration software was not uploaded in the system.
- AOH – The temperature in the internal casing of the hot tub is too high. Therefore, the temperature inside the control unit exceeded the set limits.
- OH – Water temperature reached 42°C. Do not enter the hot tub!
Preparation of the Site for the Hot Tub
Idol Spas hot tubs can be installed both indoors and outdoors. Install the hot tub on a solid level surface. We recommend concrete foundation (5 – 8cm thick). Consult any other foundation with the seller/experts. Consider the bearing capacity of up to 500kg/m2 according to the size of the bathtub. Consult the bearing capacity of elevated constructions with a structural engineer. We recommend having the foundation plate for your whirlpool bathtub built by a qualified and licenced company.
The hot tub can also be embedded into the floor. However, it is necessary to provide installation space on all sides, at least 60cm, wide for maintenance and service.
When selecting the installation site, namely for embedding, remember to provide water outlet from the hot tub in case of defects of tightness, for example. The hot tub must be installed in a way that prevents flooding of its technologies (pumps, control unit, etc.) with water either from the hot tub, or from the surroundings.
Also, consider the route for moving the hot tub in. Narrow passages, corners and narrow doors can be a problem. In the garden, it can be trees, a narrow gate, sloping terrain etc.
Before transport, the hot tub is packed into a protective film and other elements that protect it during transport. The hot tub is stored according to the transport requirements – on the side/on the bottom. The hot tub is usually transported on a pallet that facilitates manipulation.
The dimensions of the packed hot tub can be calculated by adding 5 – 7cm to its dimensions. The hot tub is transported on a pallet that is 15cm high. If you need precise dimensions for moving, consult the seller first.
The customer can use delivery services directly from IDOL SPAS. Rates per km according to the current pricelist. Hot tubs are delivered on a trailer pulled by a passenger vehicle. The technician travels alone.
The customer may arrange the transport.
Hot tubs can also be delivered by contractual carriers.
The hot tub is moved as a whole. It cannot be disassembled or otherwise made smaller. Therefore, you should always plan the method and route for moving beforehand.
Hot tubs are best moved on the pallet using a pallet truck. If required (uneven or soft terrain), it is possible to use boards as a support. If moving the hot tub is more difficult, it is necessary to reckon with several people. Always consult the number of people required to move the hot tub beforehand! It depends on the size (weight) of the hot tub and demands of the moving.
Sometimes, the easiest and often the only way is to use a crane. The hot tub does not need to be packed in a special way for this process.
When unpacking the hot tub, do not use sharp tools that could damage the acrylate or the casing.
Installation of the Hot Tub
Carefully remove the unpacked hot tub from the pallet and place it on the prepared level surface. It does not need to be fixed and anchored. Never fill up the hot tub when on the pallet! The pallet is not designed for such load and if it breaks, the hot tub can get damaged.
Filling up the Hot Tub
The hot tub does not have its own water inlet. It is filled up with a regular garden hose, 15 – 17cm below the edge. If filled up more, it can overflow when people get in the hot tub. If there is not enough water, the hot tub is not going to work properly.
Fill up the hot tub without the cartridge filter to make it easier to fill up the pipeline and to prevent air intake of the pumps.
Connecting the Hot Tub
Hot tubs must be connected to an independent circuit (no other appliance can be connected to the same circuit).
The circuit must be protected with a three-phase circuit breaker, 20A – 25A, characteristic “C” or “D” and with current protection In=0.03A.
Cable 400V 5C x 4mm2.
Make sure that the cable on the output from the electrical system of the hot tub is long enough so that it can be directly connected to the power supply. If you do not know the exact distance, leave the cable at least 5m long at the connection.
Lite 230 hot tubs are equipped with a cable with a regular 230V plug and current protection.
They can be connected to a regular single-phase socket. However, the hot tub must be connected on an independent circuit with 16A circuit breaker, characteristics C.
Attention! Only a professional can install and connect the hot tub to the power supply!
When the hot tub is filled with water, you can turn on the power supply (switch on the hot tub circuit breaker).
Set the date and time on the control panel and the control unit will then automatically run the program for first activation when it tests the installed devices and activates the pumps.
