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.

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.
