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 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 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/illness:
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. It is recommended to
seek medical advice before use.
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 temperature
and duration of use and should also seek medical advice.
DANGER
WARNING
• Risk of Accidental Drowning (especially children under 5 years). Caution shall be exercised to
prevent unauthorized access to spa by children. This can be reached by adult supervisor securing
the means of access or installing a safety protection device to the spa. To avoid accidents during
spa use, ensure that children are kept under constant supervision.
• 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. The suction fittings in this spa are sized to match the specific water flow created by
the pump. Should the need arise to replace the suction fittings or the pump, be sure that the flow
rates are compatible. Never operate 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.
• Risk of injury. Replace damaged cord immediately. Do not bury cord. Never use an extension 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.

SET UP (continued)
Setup the spa with at least 2 persons.
1. Move the entire package to the selected site. Do not drag the spa tub across the ground as this can
cause damage and leakage.
Open the carton carefully as this carton can be used to store the spa during long term storage or when
not in use.
2. Lay out all the parts on the ground and make sure all the parts are accounted for. For missing or
damaged parts contact the appropriate Intex Service Center listed in the separate “Authorized service
Centers” sheet.
Spa Control Panel Charging and Installation
1. Make sure the back of the control panel (5) and the control base recessed channel surface are clean
and dry.
2. Make sure the control base is plugged in and the RCD tested. Place the control panel (5) on the
control base recessed channel to charge the built-in battery (see drawing 1). See “Spa Control Panel”
operation section for more details.
3. Once the control panel battery is fully charged, you may place the control panel on top of the spa tub
wall (see drawing 2.1). To remove the control panel from the spa tub, lift the latch while pulling the
control panel away from the support stand (see drawing 2.2).
• 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. Provide protection from the
sun such as sunshade, tent, awning or gazebo.
• 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. Do not use the spa if the ambient or
water temperature is 4°C (39°F) or lower.

4. Before filling with water ensure the bottom drain valve caps are
securely closed on the inside and outside.
5. Fill the spa tub with freshwater to a level between MIN and MAX
marked on the inside of the spa wall. Do not over fill the spa.
Never move the spa tub with water inside and/or with the control
base attached to the spa as the spa or control base may be
damaged.
WARNING: Never pour water with a temperature higher than
40°C (104°F) into the spa directly. It is recommended to fill the
spa tub with lukewarm water for quick heating and energy saving.
6. Place the spa cover and spa air bladder (pre-installed in spa cover)
over the spa tub, and make sure the spa cover buckles are locked
using the key provided after pulling the buckled straps tight.
IMPORTANT: Inspect the spa cover regularly for leak, premature wear and tear or deterioration. Never
use a damaged spa cover.
7. Ensure that the spa base is plugged into a properly located and sized electrical outlet and press the
button to turn on the control panel. Press the button on the control panel to activate the heater, see “Spa
Control Panel” operation section.
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.
When the spa is being used, the cover should be placed in a clean, dry area, otherwise it can pick up dirt and
bacteria. Covers should not be put on wooden tables or wooden decking because of the risk of bleaching the
wood. A cover lifter, dedicated support or similar device, is recommended for ensuring that the cover, mostly its
side facing the water, does not come into contact with the ground or any other dirty surfaces.

OPERATION (continued)
Heat Button: Press this button to activate the heating system. Press or to set the
desired water temperature. The heater will continuously heat until the water temperature
reaches the set temperature and then hold at that temperature. This is achieved by the heater
restarting automatically whenever the water temperature drops 1-2°C (1.8-3.6°F) below the set
temperature. When the flame icon on the display is red, the heating system is activated. When
the flame icon turns green, the water is at the set temperature. The heating system is then at
rest, but the filtration system will continue circulating water nonstop, unless manually turned off.
If the heating system is reactivated, the filter pump will restart at the same time.
NOTE: To stop the filtration system while the heater is at rest mode, press the flame button
first and then the filter button. Pressing the heat button only while the heater is at rest mode will
turn off the heating system only and the filtration system will operate for 1 more minute before
it turns off or continue with the filter pump preset operating hours. To turn the heater off while
heating, press the flame button.
IMPORTANT: The following conditions will lead to slow water heating.
• The ambient temperature is lower than 10ºC (50ºF).
• Outdoor wind speed is above 3.5-5.4 m/s (8-12 mph).
• 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.
Heater Start Timer (HST) Button: Use this button to select a future start time for the heating
system. Press this button and then press or to set the number of hours by which you
wish to delay the start of the heating system, from 000 to 120 hours. The icon will flash red for a
few seconds and then stays red. The information shown on the LED display alternates between
the remaining hours before heater start and the water temperature. Once the countdown timer
reaches 000, the heating system will start operating. To deactivate the function at any time,
simply set the HST time back to 000. To readjust the preset hours, press the HST button twice
and adjust the hours with and buttons.
Example 1: It is 9:00pm Monday evening and you would like the spa to be hot on Friday
evening. Allowing for 24 hours for the spa to heat up (4 persons model about 1.5-2.5ºC (3-4.5ºF)
per hour) the heater should be set to start on Thursday evening. With the Spa turned on, first
press the Heat button and set your desired temperature. Press the HST button and then or
until 072 hours is shown. The heater will start after 72 hours has passed (Thursday at 9:00pm)
and will run until the desired temperature is attained. The heater will then cycle on and off to
maintain the set temperature until turned off. To turn off the heater, press the flame button.

button and then the or button to select 048 hours. The heater will then run from
Thursday at 9:00pm to Saturday at 9:00pm.
NOTE: If HST and HDT timers are both set, the LED display will first alternate between
remaining time before the heater start and the water temperature, until HST timer runs out
and the heater activates. Then the LED display alternates between remaining HDT time and
water temperature until the HDT timer runs out as well.
Adjustment Buttons: Press the increase or decrease buttons to adjust the desired function
settings. Press and hold the button will rapidly increase or decrease the numbers.

NOTE: Keep the spa control panel within 5m (16ft) range of the control base to ensure good
wireless transmission signal.
1) Always keep the spa cover on to minimize heat loss during heating of the spa between
uses (but not while it is being used). Ensure the cover is fitted tightly, as per manufacturer’s
instructions to maximize insulation. It shall be recommended that the cover, when not in
use, should be kept off the ground to retain its cleanliness (particularly the surface in close
proximity to the water spa water surface). The cover should be stored in an appropriate
location, where it cannot be damaged, or cause damage.
2) Check the set water temperature and consider lowering it for the times when the spa will
typically not be in use.
3) Depending on external conditions, consider turning off the heater entirely if not using the spa
for an extended period of time (where the spa provides this option, but still maintains residual
disinfection/pH-values).
4) Consider that the comfortable temperature range during use may be lower than the maximum
safe temperature.
5) Use the included insulating ground cloth underneath the spa to minimize heat loss through
the bottom of the spa.
6) Maintain clean filters to preserve appropriate working conditions for the pump and avoid
unnecessary water replacement and re-heating.
