INLINE MAINTENANCE HEATER WIRING AND OPERATING INSTRUCTIONS
The air-whirlpool Inline Maintenance Heater is totally self-contained to ensure trouble free operation. 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.
POWER INDICATOR:
This illuminating light plug turns on when heater is plugged into a power outlet.
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 must 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.
