WARNING23:

The appliance should be supplied power through a GFCI-equipped outlet with a rated tripping
current not exceeding 30 mA.
Electric installations should fulfill the requirements of local standards. Grounded appliances must be
permanently connected to fixed wiring.
If the power supply cord is damaged, it must be replaced by the manufacturer or its service agent or a
similarly qualified person in order to avoid a hazard. Replace damaged cord immediately.
Parts containing live current, except parts supplied with extra-low safety voltage not exceeding 12 V,
must be inaccessible to a person in the bath.
To reduce the risk of electric shock, do not use an extension cord to connect unit to electric supply;
provide a properly located receptacle.
Parts incorporating electrical components, except for remote control devices, must be located or
fixed so that they cannot fall into the bath.
To avoid electric shock, do not use the spa when it is raining.
Never operate the spa if the suction fittings are broken or missing. Never replace a suction fitting
with one rated less than the flow rate marked on the original suction fitting.
To reduce the risk of injury, do not permit children to use this product unless they are closely
supervised at all times.
Water attracts children. Always have the spa locked with its cover on after each use.
When the jet function is going to be used, make sure the cover of spa is opened first.
Do not switch on if there is any possibility that the water in the spa is frozen.
Risk of electric shock. Never operate any electrical appliance when in the spa or when your body is
wet. Never place any electric appliance, such as a light, telephone, radio, or television, within 5 feet
(1.5m) of a spa.
Pets should be kept away from spa to avoid damage and injury.
Risk of electric shock. Install spa at least 5 feet (1.5m) from all metal surfaces. As an alternative, a
Spa may be installed within 5 feet of metal surfaces if each metal surface is permanently connected
by a minimum 8-guage solid copper conductor to the wire connector on the terminal box that is
provided for this purpose.
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.
During pregnancy, soaking in hot water may cause damage to the unborn fetus. Limit use to 10
minutes at a time while pregnant.
The use of alcohol, drugs, or medication before or during the spa use may lead to
unconsciousness with the possibility of drowning.
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 they use a spa.
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. The water in a spa should never exceed 40°C (104°F). Water temperature 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. Since
high water temperature has a high potential for causing fatal damage during the early months of
pregnancy, pregnant or possibly pregnant women should limit spa water temperature to 38°C
(100°F).
To reduce the risk of injury, never fill spa with water hotter than 40°C (104°F).
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia.
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 the spa;
unawareness of impending hazard; fatal damage in pregnant women;
physical inability to exit the spa; and unconsciousness resulting in the danger of drowning.
Prolonged immersion in a spa may be injurious to your health.

INFLATABLE SPA ASSEMBLY GUIDE

1. Filling Hot Tub with Water

•

Water should be filled to a position between minimum and
maximum water line . If lower, heating may not be fully effective. If higher,
water may spill over the basin during use.

2. Water Treatment

Water in the basin should be filtered at fixed times regularly. It is not

•

suggested to filter the water at all times.

•

Water in the basin should be treated with chemical agents periodically. However, chemical agents with calcium
ions must not be used. If chemical agents with calcium ions are used for water treatment, it is very likely that
calcium scale will form on the walls of water basin and inner heating pipes.
Water scales will directly damage the inner electrical components inside the control cabinet and further affect the
service life of control cabinet.

•

If the filtration system has worked for 168 hours, the system will emit a warning tone to remind the user to clean
or replace the filter element.

3. Hot Tub Care

•

Drain off the water inside the water basin completely and wipe off droplets of water on the walls. After
that, lay aside the spa for 24 hours, exhaust the air and fold. If it is Winter, please fold the spa indoors.
Theoutside temperature in Winter is very low and materials may become hard, in that case, folding the
materials may result in breakage. Put the spa inside the packing case after folding it well and then put the
case in a shaded place to avoid direct sunlight.

MAINTENANCE

1. Maintaining Spa Water

•

Clean your filter cartridge at least once every time it has worked continuously for 72- 120 hours. The filter
cartridge should be replaced at least once a month depending on use.

•

Change water every few days or use appropriate pool chemicals. All spas require the use of pool
chemicals. Please consult your local pool supply retailer for more information about chemical
maintenance. Pay close attention to the chemical manufacturer’s instructions. Spa damage resulting from
misuse of chemicals and mismanagement of spa water is not covered by the warranty.

•

Water balance; we recommend you maintain the spa water pH between 7.2 and 7.8, total alkalinity
between 80 and 120ppm, and free chlorine between 3 to 5ppm.

•

Purchase a test kit to test your water chemistry before each use of the spa, no less than once per week. Low
pH will damage to the spa and pump. Damage resulting from chemical imbalance is not covered by the
warranty.

•

Water sanitation is the responsibility of the spa owner, achieved through the regular and periodic (daily, if
necessary) addition of an approved sanitizer. The sanitizer will chemically control bacteria and viruses
present in the fill water or introduced during use of the spa.

2. Cleaning the Filter Cartridge
Make sure to unplug the power pack from the electrical receptacle before the following actions.

•

Unscrew the filter cartridge by turning counterclockwise (Fig 1).

•

Remove the filter cartridge cover (Fig. 2).

INFLATABLE SPA ASSEMBLY GUIDE

•

The filter cartridge can be rinsed off with a garden hose and reused. However, if the filter cartridge remainssoiled
and discolored the filter cartridge should be replaced (Fig.3).

•

Re-apply filter cartridge cover and attach the filter cartridge to the water inlet by turning clockwise (Fig.4).

3.Drainage

•

Make sure to unplug the power pack from the electrical receptacle.

•

Put the plastic plug into the outlet in the inner wall of the spa.

•

Open the outlet in the outer wall of the spa. Screw one end of inflation hose into it.

•

Pull the plastic plug off from the outlet in the inner wall of the spa, then the water will flow out (Fig. 5).

•

When there is no water in the spa, you must put on the jet function for at least 5 minutes by pressing the
BUBBLE button to drain the water in the air pipeline.

•

When drainage is finished, remove the inflation hose and screw the nut tight.

Fig. 5

4. Cleaning the Spa

•

Detergent residues and dissolved solids from bathing suits and chemicals will gradually accumulate in the spa’s
water.

•

To clean the spa, use soap and water then rinse.

Note: do not use hard brushes or abrasive cleaners.

REPAIR AND STORAGE

1. Spa Repair

•

If the spa is torn or punctured, use the provided repair patch.

•

Dry the area to be repaired.

•

Apply the glue in the accessory bag to the repair patch and then attach it onto the damaged area.

•

Smooth the surface to remove any air bubbles. A secure unnoticeable repair can usually be made.

2. Spa Storage

•

Make sure all water is drained from the spa and control box. This is essential to extend the life of the spa. We
recommend the use of a wet/dry vacuum to blow out or suck up water from the spa pipes and pump lines.

•

Remove the filter cartridge.

•

It is recommended you store the spa in its original package in a warm dry place.

Note: Plastic becomes brittle and susceptible to breakage when exposed to subzero temperatures.
Freezing can severely damage the spa. Improper winterization of your spa may void your warranty.
