IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
(For units with GFCI)
WARNING – This product is provided with a ground-fault circuit interrupter locat-
ed on the front panel of selected swim spas and on the power cord of 120 volt
convertible spas. The GFCI must be tested before each use. With the product
operating, open the service door. When the product stops operating, this merely
indicates that the door is equipped with an electrical interlock. Next, push the
test button on the GFCI and close the service door. The product should not oper-
ate. Now open the service door, push the reset button on the GFCI and close the
service door. The product should now operate normally. When the product fails
to operate in this manner, there is a ground current flowing indicating the possi-
bility of an electric shock. Disconnect the power until the fault has been identified
and corrected.
DANGER – 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.
DANGER – 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.
DANGER – Risk of Electric Shock. Install 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 8AWG (8.4mm2) solid copper conduc-
tor to the wire connector on the terminal box that is provided for this purpose.
DANGER – Risk of Electric Shock. Do not permit any electric appliance, such as a light,
telephone, radio, or television, within 5 feet (1.5 m) of a spa.
WARNING – 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 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, the user should measure the water temperature 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.

WARNING – Risk of Suffocation. This spa is equipped with a gas heater and is
intended for outdoor use only unless proper ventilation can be provided for an
indoor installation.

containing electrical components so as not to damage equipment. When installing the
spa make sure to allow for an adequate drainage system to deal with any overflow
water. Please allow for at least 2 feet of clearance around the perimeter of the spa to
provide enough room to access for servicing. Contact your local dealer for their specific
requirements.
WARNING – The spa should be covered with an approved locking cover when not in

supplying this equipment.
At least two lugs marked “Bonding Lugs” are provided on the external surface or on
the inside of the supply terminal box or compartment. To reduce the risk of electric
shock, connect the local common bonding grid in the area of the spa to these terminals
with an insulated or bare copper conductor not smaller than 6AWG.

ware within 3m of the spa shall be bonded to the equipment grounding bus with cop-
per conductors not smaller than 6AWG.
