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.
• When changing the temperature, make sure to conrm with the customer that the temperature
of the hot water will be very high and that there is a risk of scalding.
• Hot water heater temperatures over 125 °F (52 °C) can cause severe burns instantly or death from scalding.
