Remote controller cord

• For extensions, a 26' (8m) cord can be purchased (Part # RC-CORD26) or use 18AWG wire.

• Install according to the National Electrical Code and all applicable local codes.

Connecting Remote Controller Cord to Unit

• Keep the remote controller cord away from the freeze prevention heaters in the unit.

• Tie the redundant cord outside the water heater. Do not put the extra length inside the equipment.

• The remote controller cord can be extended up to 300' (90m) with 18AWG wire.

• Use a Y type terminal with a resin sleeve. (Without the sleeve, the copper wire may corrode and

cause problems).

• Be sure to hand tighten when screwing to the terminal block. Power tools may cause damage to

the terminal block.

1. Check to make sure that the remote controller

cord has plenty of slack in order to reach the

external connection terminal block.

2. Disconnect electrical power to the water heater.

3. Remove the single screw securing the terminal

block cover and then remove the cover.

4. Pass the remote controller cord through the wiring

throughway and connect the Y terminals at the end

of the remote controller cord to the terminal block.

5. Replace the terminal block cover and install the

screw previously removed in step 3.

6. Reconnect electrical power to the water heater.
