The whirlpool Inline Maintenance Heater is totally self-contained to ensure trouble free operation. Operation can be
controlled from the electronic panel (see page 13 for further information). The heater will maintain the temperature
of the water in the bathtub. As with all electrical devices, certain safety precautions should be taken during wiring
and use. Please read and follow all these instructions carefully.
FEATURES OF THE INLINE MAINTENANCE HEATER
HI-LIMIT:
The heater includes an exclusive "Smart Hi-Limit." This Hi-Limit will not "false trip" from hot tap water.
It will only turn heater off if the thermostat fails. If the water temperature reaches the "High Limit", the display will
show "OH" to indicate the problem. The next touch of the control pad will try to reset the high-limit circuit.
INDICATOR LIGHT:
This light turns on when heater is operating.
SAFETY FEATURES:
In addition to the thermostat and Hi-Limit, the heater is equipped with a built-in pressure switch.
This switch will not allow the heater to turn on if the pump is not running.
WARNING:
RISK OF ELECTROCUTION!
All electrical connections should be performed by a licensed electrician in
compliance with local and national electrical codes. In addition, a GFCI
MUST
protect all branch circuits to the whirlpool.
1. One 220V, 4 wire, 50 AMP GFCI protected circuit.
2. Use copper conductors only.
3. Insure the heater and pumps are properly
GROUNDED
and pump is
BONDED
as required.
CAUTION:
Before use of the pumps and heater, test the GFCI for proper operation. The pumps and heater should
turn off when the GFCI "Test" button is pushed.
WARNING:
Prolonged Immersions in Hotter Water May Induce Hyperthermia.
Hyperthermia occurs when the internal temperature of the body reaches a level several degrees above the normal body
temperature of 98.6
o
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 (1) failure to perceive heat, (2) failure
to recognize the need to exit the whirlpool, (3) unawareness of impending hazard, (4) fetal damage in pregnant women,
(5) physical inability to exit the whirlpool, (6) unconsciousness resulting in the danger of drowning.
WARNING:
The use of alcohol, drugs, or medication can greatly increase the risk of fatal hyperthermia.
