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
• 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 the spa when it is raining, thundering or lightning.
•
The spa electrical appliance should be supplied through a residual current device (RCD) having a
rated residual operating current not exceeding 30 mA.
• The spa electrical appliance comprises a portable residual current device (PRCD) having a rated
residual operating current not exceeding 10 mA. If a leakage current of more than 10 mA is detected,
the PRCD will operate and cut-off the power supply, in such case, unplug and stop using the spa at
once. You must contact the local service center for assistance and/or repair of the product.
• Parts containing live parts, except parts supplied with safety extra-low voltage not exceeding 12 V,
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.

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.
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 18).
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 3 days. 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.
Water Chemistry Balance
Maintain the spa water pH level between 7.2 and 7.8, total alkalinity level between 80 and 120 ppm and free
chlorine level between 2 to 4 ppm. Use the included test strips to test the spa water chemistry before each use of
the spa and continue to test the water no less than once a week.
The Test Strips can test the “Free Chlorine”, “pH”, “Total Alkalinity” and “Calcium Hardness” levels at the same
time:
1. Dip the entire strip into the water and remove immediately.
2. Hold the strip level for 15 seconds. Do not shake excess water from the strip.
3. Compare the strip pad to the color chart on the packaging label. If necessary, adjust the chemical level
in the pool water.
NOTE: Check the expiry date of the test kit as the test results may be inaccurate if the kit is used after that date.
Low pH will damage the spa tub and pump. Damage resulting from chemical imbalance is not covered by the
warranty.
Use the included chemical floater dispenser to administer chlorine [chemical tablet size: less than 1” (2.5cm)
diameter] into the spa water. Add 1 tablet into the dispenser. 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.
IMPORTANT: 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.
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.
Calcium Hardness (CaCO3): refers to the amount of calcium and magnesium dissolved in the water.
Result if too low – Difficulty balancing water, corrosion of metal components, eye & skin irritation and water
foaming.
Result if too high – Scale formation, cloudy water, eye & skin irritation, difficulty balancing water and filter/
heater inefficiency.

SPA WATER CHEMISTRY AND BALANCE (continued)
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 (water volume 210 gal / 795 L), 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.
pH Adjustment
After the total alkalinity has been lowered to 120 ppm or raised to 80 ppm and the pH is still high or low, you
can adjust it using the following chart.
