SAFETY INSTRUCTIONS
IMPORTANT SAFETY INSTRUCTIONS
When installing and using this electrical equipment, basic safety precautions should
be observed including the following:
READ AND FOLLOW ALL
INSTRUCTIONS
WARNING – To reduce the risk of injury, do not permit children to use this product
unless they are closely supervised at all times.
A wire conductor is provided on this unit to connect a minimum 6 AWG
(13.302mm2) solid copper conductor between this unit and any metal equipment,
metal enclosures of electrical equipment, metal water pipe, or conduit within 5 feet
(1.5m) of the unit
(For cord-connected/convertible units)
DANGER – Risk of injury.
a) Replace damaged cord immediately.
b) Do not bury cord.
c) Connect to a grounded, grounding type receptacle only.
(For units intended for indoor use only)
WARNING – For indoor use only. This unit is not intended for outdoor use.

SAFETY INSTRUCTIONS
IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
(For units with GFCI)
WARNING – This product is provided with a ground-fault circuit interrupter
located on the front panel of selected swim spas and on the power cord of
120 volt convertible swim 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 operate. 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 possibility 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 swim spa unless they are supervised at all times.
DANGER – Risk of Injury. The suction fittings in this swim 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 swim 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 sur-
faces. As an alternative, a swim spa may be installed within 5 feet of metal surfac-
es if each metal surface is permanently connected by a minimum 8AWG (8.4mm2)
solid copper conductor 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 swim spa.
WARNING – To reduce the risk of injury:
a) The water in a swim spa should never exceed 40˚C (104˚F). Water tem-
peratures 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 swim 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 preg-
nant women should limit swim spa water temperatures to 38˚C (100˚F).
c) Before entering a swim spa, the user should measure the water tempera-
ture since the tolerance of water temperature- regulating devices varies.
d) The use of alcohol, drugs, or medication before or during swim 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 swim spa.
f) Persons using medication should consult a physician before using a swim
spa since some medication may induce drowsiness while other medication
may affect heart rate, blood pressure, and circulation.
(For swim spas with a gas heater)
WARNING – Risk of Suffocation. This swim spa is equipped with a gas heater
and is intended for outdoor use only unless proper ventilation can be pro-
vided for an indoor installation.

IMPORTANT SAFETY
INSTRUCTIONS (CONT.)
DANGER – To reduce the risk of injury to persons, do not remove the suction
grate. Suction through drains and skimmers is powerful when the jets in the swim
spa are in use. Damaged covers can be hazardous to small children and adults
with long hair. Should any part of the body be drawn into these fittings, turn off
the swim spa immediately. As a precaution, long hair should not be allowed to
float in the swim spa.
WARNING – Install the swim spa so that water can be easily drained out of the
compartment containing electrical components so as not to damage equipment.
When installing the swim spa make sure to allow for an adequate drainage sys-
tem to deal with any overflow water. Please allow for at least 2 feet of clearance
around the perimeter of the swim spa to provide enough room to access for servic-
ing. Contact your local dealer for their specific requirements.
WARNING – The swim spa should be covered with an approved locking cover
when not in use, to prevent unauthorized entry and injuries.
WARNING – People with infections, sores or the like should not use the swim spa.
Warm and hot water temperatures may allow the growth of infectious bacteria if
not properly disinfected.
CAUTION – Safe temperatures for swimming or aquatic exercise is around 80˚F.
CAUTION – Risk of Electrical Shock. Do not leave audio compartment open.
Audio controls are not to be operated while inside the swim spa.
CAUTION – Replace components only with identical components.

example, additional speakers, headphones, additional audio/ video components
etc.) to the system. These units are not provided with an outdoor antenna.

you to dangerous voltage or other hazards. Refer all servicing to qualified service
personnel.
If the power supply cord(s) are damaged, water is entering the speaker, audio
compartment, or any other component in the electrical equipment compartment
area, the protective shield is showing signs of deterioration, or there are signs of
other potentially hazardous damage to the unit, turn off the circuit breaker from
the wall and refer servicing to qualified personnel.

The unit should be subjected to periodic routine maintenance once every quarter to
make sure that the it is operating properly.
DANGER – Risk of Electric Shock. A green colored terminal or a terminal marked
G, GR, Ground, Grounding or the symbol shown in Figure 14.1 of UL 1563 is locat-
ed inside the supply terminal box or compartment. To reduce the risk of electric
shock, this terminal must be connected to the grounding means provided in the
electric supply service panel with a continuous copper wire equivalent in size to the
circuit conductors 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 swim spa
to these terminals with an insulated or bare copper conductor not smaller than
8AWG.
All field installed metal components such as rails, ladders, drains, or other similar
hardware within 3m of the swim spa shall be bonded to the equipment grounding
bus with copper conductors not smaller than 8AWG.
