IMPORTANT SAFETY RULES
When installing and using this electrical equipment, basic safety precautions should always be followed, including the following.
READ AND FOLLOW ALL INSTRUCTIONS
• The spa electrical appliance should be supplied through a residual current device (RCD) having a
rated residual operating current not exceeding 10 mA.
• Parts containing live parts, except parts supplied with safety extra-low voltage not exceeding 12V,
must be inaccessible to a person in the spa.
• Electrical installation shall fulfill the requirements of local national standards.
• Parts incorporating electrical components, except remote control devices, must be located or fixed so
that they cannot fall into the spa.
• To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
• Children should not use spas or hot tubs without adult supervision.
• To reduce the risk of child drowning, supervise children at all times. Attach and lock spa cover after
each use.
• To reduce the risk of injury:
a)The water in a spa should never exceed 40°C (104°F). Water temperatures between 38°C (100°F)
and 40°C (104°F) are considered safe for a healthy adult. Lower water temperatures are
recommended for young children and when spa use exceeds 10 minutes.
b)Since excessive water temperatures have a high potential for causing fetal damage during the early
months of pregnancy, pregnant or possibly pregnant women should limit spa water temperatures
to 38°C (100°F).
c)Before entering a spa or hot tub, the user should measure the water temperature with an accurate
thermometer since the tolerance of water temperature-regulating devices varies.
d)The use of alcohol, drugs, or medication before or during spa use may lead to unconsciousness with
the possibility of drowning.
e)Obese persons and persons with a history of heart disease, low or high blood pressure, circulatory
system problems, or diabetes should consult a physician before using a spa.
f) Persons using medication should consult a physician before using a spa since some medication may
induce drowsiness while other medication may affect heart rate, blood pressure, and circulation.
DANGER
WARNING
• Risk of Accidental Drowning. Extreme caution must be exercised to prevent unauthorized access by
children. To avoid accidents, ensure that children cannot use this spa unless they are supervised at
all times.
• Risk of drowning. Inspect the spa cover regularly for leaks, premature wear and tear, damage, or
signs of deterioration. Never use a worn or damaged cover: it will not provide the level of protection
required to prevent unsupervised access to the spa by a child.
• Risk of injury. Replace damaged cord immediately. Do not bury cord.
• Risk of Electric Shock. Do not permit any electric appliance, such as a light, telephone, radio, or
television, within 3.5 m (11.5 feet) of a spa or hot tub.
• Risk of Electric Shock. Do not use and unplug the spa when it is raining, thundering or lightning.

• To avoid injury exercise care when entering or existing the spa or hot tub.
• Do not use drugs or alcohol before or during the use of a spa or hot tub to avoid unconsciousness
and possible drowning.
• Pregnant and possible pregnant women should consult a physician before using a spa or hot tub.
• Water temperature in excess of 38ºC degree may be injurious to your health.
• Do not use a spa or hot tub immediately following strenuous exercise.
• Prolonged immersion in a spa or hot tub may be injurious to your health.
• When pregnant, soaking in hot water for long periods can harm your fetus. Measure the water
temperature before entering. Do not enter spa if water is hotter than 38°C (100°F). Do not stay in
spa for longer than 10 minutes.
• Spa heat in conjunction with alcohol, drugs, or medication can cause unconsciousness.
• Exit immediately if uncomfortable, dizzy, or sleepy. Spa heat can cause hyperthermia and
unconsciousness.
• The causes, symptoms, and effects of hyperthermia may be described as follows: Hyperthermia
occurs when the internal temperature of the body reaches a level several degrees above the normal
body temperature of 37°C (98.6°F). The symptoms of hyperthermia include an increase in the
internal temperature of the body, dizziness, lethargy, drowsiness, and fainting. The effects of
hyperthermia include failure to perceive heat; failure to recognize the need to exit spa or hot tub;
unawareness of impending hazard; fetal damage in pregnant women; physical inability to exit the spa
or hot tub; and unconsciousness resulting in the danger of drowning.
• The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia in hot tubs
and spas.
• Always add chemicals to water, never add water to chemicals. Adding water to chemicals may cause
strong fumes or violent reactions and hazardous chemical spray.
• Never jump or dive into a spa or any shallow body of water.
• Assembly and disassembly by adults only.
• This appliance can be used by children aged from 8 years and above and persons with reduced
physical, sensory or mental capabilities or lack of experience and knowledge if they have been given

Site preparation and requirements
• The spa can be installed indoor or outdoor. For household use only.
• Make sure the area is free of sharp objects under or around the spa.
• Provide a properly located power outlet to connect the spa and allow easy access for periodic testing of the cord
mounted RCD.
• Make sure there is enough clearance around the spa for full access to the spa equipment for maintenance and/or
service.
• The area shall facilitate draining purposes during long term spa storage.
Additional requirements for indoor installation
• Make sure the floor can support the full weight of the filled spa with the maximum number of occupants. Check with a
qualified contractor or a structural engineer to verify this requirement.
• Make sure the floor is water resistant and non-slip surface. Do not install the spa on carpet or other materials that will be
damaged by moisture, condensation.
• Do not install the spa indoors on a second floor above finished living space due to the possibility of water and humidity
damage.
• Humidity is a natural side effect of indoor spa installation. The room shall be properly ventilated to allow moisture to
escape. Install a ventilating system to prevent excess condensation, moisture in the room.
Additional requirements for outdoor installation
• Spa owners may need to comply with local or states laws relating to childproof fencing, safety barriers, lighting, and
other safety requirements. Contact your local building code enforcement office for further details.
• Make sure the surface is level, flat, smooth and strong enough to support the full weight of the filled spa.
• Do not setup the spa on grass or dirt, as this increases the amount of debris entering the spa, and damage the spa floor.
• Do not expose the spa to direct sunlight for extended period of time.
• It is possible to install and leave the spa outside at a temperature not lower than 4°C (39°F) provided the water
temperature inside the spa is higher than 4°C (39°F) and the water inside the circulation system, pump, pipe are not
frozen. Put a “temp barrier mat” between the spa floor and the ground to prevent heat loss from the bottom of the spa
and to provide better heat retention.

The spa comes with a built-in saltwater sanitation system. Common salt (sodium chloride) is
made up of two elements, sodium and chloride. During the installation of the device, a
measured quantity of salt is dissolved in the SPA water to make it slightly salty. The SPA water
flows through the sanitation system’s electrolytic cell to produce chlorine. The chlorine dissolves
in the water and instantly starts destroying bacteria and algae. It also oxidizes all other organic
materials.
• Which kind of salt to use:
Use only Sodium Chloride Salts
Use only sodium chloride (NaCl) salt that is at least 99.9% pure. It is also acceptable to use water
conditioning salt pellets (the compressed forms of evaporated salt). However, it will take a longer
time for them to dissolve. Do not use iodized or yellow (yellow prussiate of soda) colored
salt. Salt is added to the SPA water and the electrolytic cell uses the salt to create chlorine. The
purer the salt the better the performance of the electrolytic cell.
• Optimum Salt Levels
The ideal salt level in the SPA water is between 2000-3000 ppm (parts per million). The optimal
level is 2500 ppm.
A too low salt level will reduce the efficiency of the sanitation system and result in low chlorine
production. Too high a salt level may damage the power supply and cause corrosion to metal
fixtures and accessories. The salt in the SPA is constantly recycled. The loss of salt is due only to
SPA water being physically removed from the SPA. Salt is not lost due to evaporation.
• Adding Salt
1. Switch the JET pump on to start the water circulation.
2. Keep the sanitation system turned off.
3. Evenly spread 4.4 lbs / 2 kg of salt around the inside perimeter of the SPA.
4. Brush the SPA bottom to speed up the dissolving process. Do not allow salt to pile up on the
bottom of the SPA. Run the JET pump for one hour to thoroughly dissolve the salt.
5. When all the salt is dissolved, press the sanitizer button to activate the sanitation system
(see “Sanitation System Operating Instructions” section), code “003H” is flashing and set the
sanitation system to desired operating hours. NOTE: DO NOT press any other buttons on the
control panel, ensure the heater is off and attach the spa cover during the sanitizing process.
• Removing Salt if Salt Level is too high
If too much salt has been added, the unit will beep and display “E92” (see “LED Code Chart”). If
this happens, turn off the sanitation system by pressing the ON/OFF button , and unplug the
spa. You will need to lower the salt concentration. The only way to do so is to partially drain the
SPA and refill it with fresh water. Drain and refill approximately 25% of the SPA water until the “E92”
alarm code disappears.
• Adding Salt if Salt Level is too low
If not enough salt has been added, the unit will beep and display “E91” (see “LED Code Chart”).
If this happens, turn off the sanitation system by pressing the ON/OFF button , unplug the
spa and wait 10 seconds. Plug and turn on the spa, add 1.1 lbs / 0.5 kg increment of salt until the
“E91” alarm code disappears (see “Adding Salt” section).

MAINTENANCE AND CHEMICALS
Water Sanitation
The spa owner must regularly check and keep the spa water sanitized with scheduled maintenance (daily, if
necessary). Adding sanitizer and other chemical will control bacteria and viruses present in the spa water.
The maintenance of a proper water balance through appropriate use of sanitizers is the single most important
factor in maximizing the life and appearance of the spa tub as well as ensuring clean, healthy and safe water.
Proper technique is important for water testing and treating the spa water. See your pool/spa professional for
chemical, sanitizer, test kits and testing procedures questions.
CATUTION: ALWAYS FOLLOW THE CHEMICAL MANUFACTURER’S DIRECTIONS, AND
THE HEALTH AND HAZARD WARNINGS.
Do not add chemicals if the spa is occupied. This can cause skin or eye irritation. Concentrated chlorine
solutions can damage the spa tub. In no event is Intex Recreation Corp., Intex Development Co. Ltd., their
related companies, authorized agents and service centers, retailers or employees liable to the buyer or any
other party for costs associated with the loss of spa water, chemicals or water damage.
WARNING
Always unplug this product from the electrical outlet before removing, cleaning, servicing or
making any adjustment to the product.

Free chlorine: is the chlorine residual present in the spa water.
Result if too low – Inadequate level of disinfection.
Result if too high – cause odor problem, skin & eye irritation, corroded metals and other materials.
pH: a value that indicates how acidic or basic the spa water is.
Result if too low – Corroded metals, eye & skin irritation, and destruction of total alkalinity.
Result if too high – Scale formation, cloudy water, shorter filter/heater runs, eye & skin irritation, poor chlorine
efficiency.
Total Alkalinity (TA): indicates the degree of the water’s resistance to pH change. It determines the speed
and ease of pH change, so always adjust total alkalinity before adjusting the pH level.
Result if too low – Corroded metals, eye & skin irritation. Low alkalinity will cause the pH to be unstable.
Result if too high – Scale formation, cloudy water, shorter filter/heater runs, eye & skin irritation, high chlorine
demand.

SPA Water Adjustment
How to adjust the spa water chemistry when the levels are off the range. CAUTION: Always follow the
chemical manufacturer’s directions, and the health and hazard warnings.
Total Alkalinity (TA) Adjustment
Remove the spa cover to aerate the water and use the included test strips to check the chemistry level.
Ensure the chlorine level in the water is between 2-4 ppm first, as chlorine will affect the TA test result.
If the TA level (and not the pH) is higher than 120 ppm, to lower the TA level, you add muriatic acid (hydrochloric
acid) or sodium bisulfate.
If the TA level is lower than 60 ppm, you add sodium bicarbonate.
For example, if the TA level is 180 ppm, the desired decrease is 60 ppm, from below chart, you need to add
0.269 Lb (121 g) of sodium bisulfate or 0.101 qt (96 ml) of muriatic acid
If the test strip color is between 180 ppm and 240 ppm, and close to 180 ppm, you can also add 0.269 Lb
(121 g) of sodium bisulfate or 0.101 qt (96 ml) of muriatic acid.
If the reading is more than 240 ppm, you can add sodium bisulfate or muriatic acid to the water drop by drop
until the test strip indicates a 240 ppm reading, then add 0.528 Lb (238 g) of sodium bisulfate or 0.202 qt
(192 ml) of muriatic acid.
NOTE: After adjustment, retest the water after 24 hours and adjust again if necessary.

MAINTENANCE
IMPORTANT
Unplug the power cord before cleaning the system. Cover the water inlet and outlet with
the plugs to prevent water spillage. After completing all maintenance tasks, you must
plug the power cord back in and remove the plugs.
Electrolytic Cell Cleaning
The electrolytic cell has a self cleaning function incorporated into the electronic control's programming. In
most cases this self cleaning action will keep the cell working at optimum efficiency. In some regions, the
SPA water is hard (high mineral content) which varies depending on the local water condition, this would
cause deposits on the titanium plate and affect the sanitizing efficiency, so the cell may require periodic
manual cleaning. To maintain maximum performance, we recommend that you open and visually inspect
the electrolytic cell every two weeks for SPA water (Calcium hardness < 100 ppm) or weekly for SPA water
(Calcium hardness > 350 ppm).
The following steps provide instructions on how to clean the cell.
Inspection and cleaning:
1. Turn off the spa and unplug the power cord from the electrical socket.
2. Unscrew the filter cartridge assembly from the spa stub wall, and use the included plugs (15 & 23) to
cover the water inlet and outlet fittings from inside of the spa tub to prevent water from flowing out.
3. Remove the four screws from the transparent cover using a Phillips screwdriver (not included) and
remove the cover from the spa control unit.
Maintenance of Spa Water and Cartridge
Protect all the spa occupants from possible water-related illnesses by keeping the spa water clean and
sanitized. Always practice good hygiene. To ensure proper spa water quality follow these procedures:
1. Inspect and clean the filter cartridge every day, and change the filter
cartridge every 3 days.
a. Unscrew the cartridge housing assembly from the spa tub wall
and remove the cartridge (see drawing 11).
b. Use a garden hose to rinse off the cartridge. If the cartridge
remains soiled and discolored it should be replaced. Keep spare
cartridges on hand.
c. Reinstall the clean cartridge back into the cartridge housing and
replace the cartridge housing assembly back onto the spa tub wall.
2. Change the spa water every 2 weeks. See “Spa Tub Drainage” and
“Spa Tub Cleaning” sections for details.
3. Use spa chemicals to maintain proper water chemistry. Spa damage
resulting from misuse of chemicals and mismanagement of spa water
is not covered by the warranty.
4. All occupants must shower before entering the spa.
