Heater must be connected to a GFCI protected branch circuit.
Before installing the heater, it is extremely important you verify the heater is configured for the correct supply
voltage. The Com-Pak Bathroom Heater is configured for 240-Volt operation by default. For 120-Volt installation
you must reconfigure the heater wiring. Installing the heater without configuring for the correct voltage will
destroy the heater and void your warranty.
How to determine the supply voltage:
If replacing an existing heater, check the labels of the old heater and replace using same voltage. For new
construction, heater wires must be configure
d to the same voltage as the supply wires. If you need assistance,
consult a qualified electrician.
