Wire Connections
HOW TO CHANGE THE WATTAGE
Your heater has two connection wires and the wall can has a green grounding wire. Your supply wire
has two connection wires and a supply ground wire.
1. Connect supply ground wire to green grounding wire in wall can (See Figure 3).
2. Connect one of the supply wires to one of your heater wires with a wire connector (not included):
A. for 240 volts, it doesn’t matter which heater wire (Figure 3);
B. for 120 volts, connect the neutral (white) supply wire to the white heater wire (Figure 3).
3. Connect the remaining supply wire to the remaining heater wire with a wire connector (not
included) (See Figure 3).
4. Insert the bottom edge of the heater
assembly into the bottom of the wall
can (See Figure 3).
5. Push all wires back into the side of
the wall can. Make sure connections
are tight and none of the wires are
caught between the heater assembly
and the wall can.
6. Attach the heater assembly at top of
the wall can with screw provided.
Multi-watt RM models offer a variety of heat output options. They are factory set to maximum wattage
(Figure 4). If you have a multi-watt model, you can change the heating element wire connections to a
lower wattage on the right hand side of the heater assembly (See Figures 5 and 6).
If you change the wattage, mark the wiring diagram on the back of the heater with the wattage used
for future reference. Proceed to STEP 4.
