PART 6 – WIRING
To avoid electrical shock, turn off all power to the heater prior to opening an electrical box within the unit. Ensure the power remains off
while any wiring connections are being made. Failure to follow these instructions could result in component or product failure, serious
injury, or death. Such product failure IS NOT covered by warranty.
Jumping out control circuits or components WILL VOID product warranty and can result in property damage, personal injury, or death.
A. LINE VOLTAGE INPUT
The heater must be wired to a 115 volt circuit by a qualified electrician. It is recommended that the heater be wired on its own circuit to
minimize the possibility of circuit failure due to outside causes. The heater requires a maximum of 8 amps at 120 volts in use.
B. LINE VOLTAGE CONDENSATE OUTPUT
The heater has the capability of supplying power to a condensate pump. The connection is 115 VAC + 10% / - 15% at a max of 2 amps.
Power is supplied to the pump only when the heater is connected to power, and the power switch is in the on position.
C. LOW VOLTAGE OUTDOOR SENSOR INPUT
The heater has the capability of an outdoor reset. Connecting an outdoor sensor allows the heater to operate at optimum efficiency.
Westinghouse offers an outdoor sensor.
The outdoor sensor must be a 12K NTC sensor. Use a minimum 22 AWG wire for runs of 100 feet or less and minimum 18 AWG wire
for runs up to 150 feet. Instructions are included with the outdoor sensor to correctly mount the sensor on the exterior surface of the
building. It is preferable to mount the sensor on the north side in an area that will not be affected by direct sunlight but will be exposed
to varying weather conditions. Connect the outdoor sensor to terminals marked "Outdoor".
It is of extreme importance that this unit be properly grounded. It is very important that the building system ground is inspected by a
qualified electrician prior to making this connection. Electrical power must only be turned on when the heater is completely filled with
cold water.
