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. If a leakage current of more than 10mA is
detected, the RCD 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 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 the spa when it is raining, thundering or lightning.

g)People using medications and/or having an adverse medical history should consult a physician
before using a spa or hot tub.
h)Check with a doctor before use if pregnant, diabetic, in poor health, or under medical care.
• People with infectious diseases should not use a spa or hot tub.
• 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
supervision or instruction concerning use of the appliance in a safe way and understand the hazards
involved. Children shall not play with the appliance.
Cleaning and maintenance must be performed
by an adult above 18 years old, and who is familiar with the risk of electric shock.
• No part of the electrical appliance is to be located above the bath during use.
• Keep the plug of this product more than 4m away from the spa and at a height of 1.2m at least.
•
Always unplug this product from the electrical outlet before removing, cleaning, servicing or making
any adjustment to the product, and on raining days.
• Do not bury the electrical cord. Locate the cord where it will not be damaged by lawn mowers, hedge
trimmers and other equipment.

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.

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 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 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 120ppm and free
chlorine level between 2 to 4ppm. 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 activate the jet system 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.

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.
Saturation Index (SI): temperature, calcium hardness concentration, total alkalinity and pH represent the
main factors influencing scale formation. The tendency of water to either form scale or corrode is indicated by
the Saturation Index (SI):

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.

Spa Tub Drainage
1. Turn off and unplug the spa control unit.
2. Connect the drain valve adaptor to a garden hose and point the other end
of the garden hose to a suitable draining area (see drawing 12).
3. Remove the drain valve cap from outside of the spa tub and attach the
drain valve adaptor to the drain valve (see drawing 12).
4. From inside of the spa tub, open the drain valve cap, water will start
flowing out from the garden hose.
5. When the water stops draining, disconnect the spa control unit from
the spa tub wall. Lift the spa tub wall from the side opposite the drain,
leading any remaining water to the drain and emptying the spa completely
(see drawing 13).
6. Turn over the spa tub to empty any remaining water (see drawing 14).
7. Unscrew the drain valve on the spa control unit side using a coin to drain
out any water (see drawing 15).
8. Use a clean towel to wipe up any remaining water and moisture on the
spa tub and spa control unit.
9. Ensure the spa tub and spa control unit are thoroughly dried.
NOTE: The enclosed plugs (15 & 23) can be used to cover the water
inlet and outlet connectors from the inside of the spa tub to prevent water
from flowing out.
Spa Tub Cleaning
If dirt is visible in the water or water becomes cloudy and proper water
chemistry does not clear it up, change the water and clean the spa tub.
See “Spa Tub Drainage” section on how to drain the spa.
While empty, remove the cartridge housing from inside of the spa tub wall,
clean and/or replace the filter cartridge. 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.
IMPORTANT: Do not use steel wool, hard brushes or abrasive cleaners.
Spa Tub Air Valve Fastening
Check the spa tub air valve for leakage and tightness before use. If air is leaking
from the air valve, use the provided wrench (22) to tighten the air valve as follow:
1. Make sure the spa tub is deflated, open the air valve cap and insert the
wrench
(22) into the air valve body (see drawing 16).
2. With one hand, hold the backside of the air valve base from the inside of
the spa tub wall and turn the wrench (22) clockwise.
IMPORTANT: Never adjust the air valve base when the spa is in use or
filled with water. Only use the air valve wrench if the air valve is loose or there is leakage around air valve
base. Do not over tighten the air valve: over tightening can damage the valve. Just ensure the air valve is
snug and not leaking.
Spa Cover
The attachment buckles of the cover are locking buckles. Two keys are provided in the plastic bag with the manual
and other accessories. Each buckle is marked with “locked” and “unlocked” symbols for easy operation: put the
key into the slot on the buckle and turn it to the appropriate position to lock or unlock the buckle respectively.
To assure safety from unauthorized access, always put the cover on when spa is not in use and lock all buckles.
Always keep the keys out of reach of children. In case you misplace the keys, you can use any similar size flat
screwdriver to lock or unlock the buckles.
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.
