FREQUENTLY ASKED QUESTIONS - PureSpas
What size is the INTEX spa tub? What is the water capacity?
It is 77” x 28” (196cm x 71cm)/79”x28” (201cm x 71cm) in size. The water capacity of the Spa is 210 gal (795 L) when filled to the MAX water level mark.
Can I use other brand of filter cartridge for the SPA?
No, the filter cartridge made by other manufacturers might not fit or function properly.
What is the spa operating minimum and maximum water temperature?
The spa operates within water temperatures from 39ºF (4ºC) to 104ºF (40ºC). The water in the spa should never exceed 104ºF (40ºC). The overheating alarm will be activated displaying code “E95” if the temperature of the water exiting the heater unit is higher than 122ºF (50ºC), and the spa control unit will stop working. If this happens, unplug and plug back in the GFCI/RCD and test the GFCI/RCD to restart the system. When the water has cooled down to 104ºF (40ºC), reset the control panel information by pressing the RESET button located on the spa control base lower side. See owner’s manual for details.
What is the power requirement for my spa?
A dedicated grounded electrical outlet rated 220-240V 50Hz and 10-16 Ampere.
Do I need a permit for the Spa?
Please check with your local building authority for any requirements which may include: a permit, fencing, door and or window alarms, pool alarm, or other safety devices.
How high of the water temperature can the spa control unit produce?
According to various international standards (UL, CSA, EN & IEC), the maximum water temperature in the spa should not exceed 104ºF (40ºC). The Spa control unit is therefore programmed to stop heating the water whenever the maximum temperature of 104ºF (40ºC) is reached.
Where and on what kind of surfaces can the spa be safely set up?
The spa can be installed indoor or outdoor. The surface where to set up the spa should be level, flat, smooth, free of sharp objects, have adequate drainage system, and capable of supporting the maximum load of the filled spa with four adult occupants, which is 2,500 lbs (1,136 kg). Use the included ground cloth to protect the spa floor and prevent heat loss through the spa floor.
To what level should I fill my spa tub to? What is the water depth at the MAX recommended spa water level?
Water should be filled between the MIN and MAX level marked on the inside of the spa wall. The MAX water depth of the spa is approximately 20 inches (52 cm).
Can I fill the spa with hot water?
You may use heated water to fill the spa, which will shorten the initial heat-up time. However, make sure not to use water exceeding the normal spa operating temperatures which are not to exceed 104°F (40ºC). Water over 104°F (40ºC) will turn off the heating unit and is not considered safe. Always check the water temperature in your spa before use and refer to the manual for detailed information on safe use.
Why is the display control panel blank?
Make sure the pump is plugged into the electrical outlet, there is power to the outlet, and the GFCI/RCD is not tripped or faulty (test the GFCI/RCD if necessary). In some outdoor conditions bright daylight may make the display hard to see. Create some shade over the control panel and make sure if the display is truly blank.
Can I use other inflation pumps to inflate my spa?
It is okay, but we don’t recommend it. Do not over inflate or use high pressure air compressor to inflate. Depending on the model of your spa, the air bubble spa control base comes with a built-in inflation system that allows proper inflation of your spa. We highly recommend using its inflation system for inflation.
I turn on the heat but the water does not feel warm coming into the spa.
The water temperature rises 2-3ºF (1-1.5ºC) per hour. As with any large volume of water, it will take time to heat it up. Be aware that the initial heating after filling may take as long as 20 hours to reach the maximum temperatures depending on the starting temperature of your fill-water and external conditions. If you do not feel heated water after the first few hours, it does not mean your spa is not working. Give it appropriate time to properly heat up and make sure to always keep the cover on when the spa is not in use.
Can I set up my spa on a slope?
No, the ground must be perfectly flat and level. Unevenly positioned Spa could become unstable and unsafe.
Can I set up my Intex spa on grass, sand or dirt? If not, why?
No, do not set up the spa on grass, sand, or dirt, as this increases the amount of debris entering the spa. Certain types of grass may grow through the spa tub floor causing leakage and damage.
The wall of my spa tub becomes soft after 5-7 days of being inflated. What should I do?
The air naturally expands and contracts with variation of air temperature, thus causing variation of pressure, too. At higher air temperatures (on hot days) the air inside the spa wall expands and the pressure increases, whereas at lower air temperatures (on cold days or during night) the air inside the spa wall contracts and the pressure decreases giving a false impression that the spa tub or cover bladder have lost air. Do not over-inflate the spa tub and spa cover air bladder, and make sure the air valve is firmly secured and properly closed (consult manual for proper air valve operation). If the spa wall is very soft, add some air.
Why does the water temperature drop quickly and water does not keep warm?
It depends on the ambient temperature where you use your spa. We recommend using the spa indoor for optimum performance. Following factors will cause the water temperature to drop:
Ground cloth missing or cover not attached
- Low ambient temperature
- Strong Wind if the spa is used outdoor
- Activated air bubble function
How long will it take to warm the spa water?
The water temperature rises 2-3ºF (1-1.5 ºC) per hour. As with any large volume of water, it will take time to heat it up. Be aware that the initial heating after filling may take as long as 20 hours to reach the maximum temperatures depending on the starting temperature of your fill-water and external conditions. The following condition will lead to slow water heating:
The ambient temperature is lower than 50ºF (10ºC).
- Outdoor wind speed is above 8-12 mph (3.5-5.4 m/s).
- The air bubble function is activated when heating the spa water.
- The spa is not properly covered with the spa cover when the water is heating.
How do I know my Intex spa tub is properly inflated?
Inflate the spa tub wall until it is firm to the touch, then attach the pressure gauge to the air valve. The pressure gauge indicator should be in the green area for a properly inflated spa tub. Pay attention to air temperature variation! In cold weather the spa tub will lose some pressure due to air contracting. If this occurs, DO NOT add air since the air inside will expand again once the temperature RISES. You should check the air pressure in hot weather, and if the pressure gauge indicator is in the red area (indicating overpressure), let some air out to prevent the spa wall or inflatable cover air bladder from failing due to excess internal pressure.
Can I leave the spa water heated all the time?
Yes, you may set an idle water temperature to be maintained. Make sure the spa is always covered when not in use, and the spa water is properly treated with chemicals for proper water balance (refer to the owner’s manual for basic water sanitation guidelines and consult your local pool/spa professional).
How often should I clean and change the filter cartridge?
Different territories have different recommendations for filter cartridges. In the U.S. and Canada it is recommended to inspect and clean the filter cartridge once a week, and change the filter cartridge as needed. Internationally, it is recommended to inspect and clean the filter cartridge every day, and change the filter cartridge as needed.
How often should the spa water be changed?
Different territories have different recommendations for water replacement. In the U.S. and Canada it is recommended to change the spa water every 2-3 months, or when it becomes cloudy and proper water chemistry does not clear it up. Internationally, the recommendation is to change the spa water every 3 days, or when it becomes cloudy and proper water chemistry does not clear it up.
Can the heating system be activated separately without filtration function?
No. The heating system works in conjunction with the filter pump as the water needs to be driven through the heating element.
I found algae in my spa tub. What should I do?
The filter pump and cartridge are designed to filter suspended particles from water, but they will not prevent algae from growing in the spa water. You will have to sanitise the spa water before further use. See the manual for basic water sanitation guidelines and use included chemical floater dispenser to administer chlorine into the spa water. Always follow the chemical manufacturer’s directions. Never let chlorine come in contact with the spa tub if it is not completely dissolved. Likewise with liquid chlorine; mix it immediately and thoroughly with the spa water. Press the bubble button on the spa control panel to turn on the bubble air blower and help dissolve the chemicals into the water. Never mix chemicals together. Add the chemicals to the spa water separately .Thoroughly dissolve each chemical before adding another one to the water. ALWAYS ADD CHEMICALS TO WATER, NEVER WATER TO CHEMICALS! Remove the chemical floater dispenser before spa use once clean and properly balanced water is established. Contact your local pool/spa professional for chemicals, sanitisers, test kits and water testing procedures.
How to clean and replace the filter cartridge?
a) Unscrew the cartridge housing assembly from the spa tub wall and remove the filter cartridge from the housing.
b) Use a garden hose to rinse off the cartridge. If the cartridge remains soiled and discoloured it should be replaced. Keep spare cartridges on hand.
c) Place the clean cartridge back into the cartridge housing and reinstall the cartridge housing assembly back onto the spa tub wall.
What should I use to clean my spa?
Use a sponge and mild soap solution to wipe away any soil or stains on the inside of the spa wall. Rinse thoroughly before refilling with clean water.
Can or should I add chemicals into my spa water, and how do I do it?
Yes, adding sanitiser and other chemical are necessary to control bacteria and viruses present in the spa water. Contact your local pool/spa professional for chemicals, sanitisers, test kits and water testing procedures. Use the included chemical floater dispenser to administer chlorine into the spa water. Always follow the chemical manufacturer’s directions. Remove the chemical floater dispenser when the spa is in use. Never let chlorine come in contact with the spa tub if it is not completely dissolved. Likewise with liquid chlorine; mix it immediately and thoroughly with the spa water. Press the button on the spa control panel to turn on the bubble air blower and help dissolve the chemicals into the water. Never mix chemicals together. Add the chemicals to the spa water separately .Thoroughly dissolve each chemical before adding another one to the water. ALWAYS ADD CHEMICALS TO WATER, NEVER WATER TO CHEMICALS!
Can I leave my INTEX spa outside in the winter?
It depends on where you live. Do not leave the spa outside with water at a temperature lower than 39ºF (4ºC), as the spa tub may freeze in such weather condition and cracking may occur. The water temperature inside the spa should be higher than 39ºF (4ºC) and the water inside the circulation system, pump, pipe should not be frozen. If freezing temperatures are expected, disassemble the spa and store it in a dry place with non-freezing temperature.
Why is the spa water not warming up?
First make sure you have given it enough time to heat up considering that water temperature rises at a rate of 2-3ºF (1-1.5ºC) per hour. Then, please check and make sure the heater is activated with the “flame” icon on the control panel lit. The following factors will lead to slow water heating:
The spa is not properly covered with the spa cover when the water is heating.
- The ambient temperature is lower than 50ºF (10ºC).
- Wind speed is above 8-12 mph (3.5-5.4 m/s) (outdoor setup).
- The air bubble function is activated when heating the spa water.
What does code E90 mean? What should I do if code E90 appears on my air bubble spa control panel?
If alarm code E90 is displayed on the control panel, it means no water is flowing through the system. Check the troubleshooting guide.
What does code E94 mean? What should I do if code E94 appears?
If alarm code E94 is displayed on the control panel, it means the water temperature is too low. If alarm code E94 appears, unplug and plug back in the GFCI/RCD and test the GFCI/RCD to restart the system when the spa water temperature is higher than 39ºF (4ºC).
What does code E95 mean? What should I do if code E95 appears?
If alarm code E95 is displayed on the control panel, it means the water temperature is too high. If alarm code E95 appears, unplug and plug back in the GFCI/RCD and test the GFCI/RCD to restart the system. When the water has cooled down to 104ºF (40ºC) or below, reset the control panel information by pressing the RESET button. See owner’s manual for details.
What does code E97 mean? What should I do if code E97 appears?
If alarm code E97 is displayed on the control panel, it means there is a heater fuse error. If alarm code appears on the control panel, unplug and plug back in the GFCI/RCD and test the GFCI/RCD to restart the system. If problem persists, please contact Intex service centre for assistance.
What does code “END” mean? What should I do if code END appears?
If alarm code “END” is displayed on the control panel, it means that the actual water temperature could not rise to the set temperature after 72 hours of continuous heating causing the rapid heating and water filtration functions to be temporarily disabled. If alarm code “END” appears, press any button (except the “RESET” button) on the control panel (i.e. the water filtration button or heating button) to restart the control system. Then re-activate the heating and water filtration system by pressing the heating button.
Why does heater “flame” icon not light up on the display control panel?
The set temperature is lower than the initial water temperature. Increase the set water temperature on the control panel if necessary for the desired water temperature.
I lost the key to lock/unlock the spa cover buckles. What can I use to lock/unlock the spa cover buckles?
You may use a small flat screwdriver or a small key or any small flat rigid strip to lock/unlock the spa cover buckles.
The spa keeps tripping the household fuse breaker. What do I do?
Please test whether the GFCI/RCD is faulty or not, following the instructions in the manual. If the GFCI/RCD is good, then the tripping might be an indication that the circuit is overloaded. You should either remove all other appliances plugged into that circuit or use another circuit dedicated only to the SPA. If this does not correct the tripping problem contact a qualified electrician.
What should I do if my spa tub or spa cover air bladder does not hold air?
First, make sure the air valve is firmly secured and properly closed (consult manual for proper air valve operation), then use the back of your hand to feel if there is any leakage on the Spa tub or cover air bladder. If no leakage is located, you can also put liquid soap in a squirt bottle and spray it onto the seams and around the valve base. If there is a leak it will create bubbles revealing the air leak. After the leakage is located, repair it with a repair patch or repair kit that is available for purchase from the local service centre.
Why does the temperature displayed on the control panel differ from the actual water temperature?
The tolerance of water temperature regulating devices may vary as much as +/-2ºC (5ºF). Measure the water temperature with an accurate thermometer before entering the spa.
Is a fence or enclosure required by law?
Most cities and towns require owners of certain types of pools, spas or hot tubs, based on their size and depth to fence the area where the pool, spa or hot tub is located. Check with your local authority for fencing requirements.
