Connect these two wires to the two wires on the water

 

heater using wire nuts or other connectors.

6.

Connect the free ends of the two wires to the shut off

 

switch on the condensate pump in accordance with the

 

manufacturers recommendations.

7.

Turn on electrical power to the water heater.

8.

Press the power button to turn the water heater on and

 

select the desired operational mode. After about 8

 

minutes, the heat pump will turn on.

Test the operation of the shut off switch by unplugging

 

the condensate pump and filling the condensate

 

reservoir with water until the float switch opens the

 

circuit.

Insulation Blankets

The use of an insulation blanket on this water heater is not needed or recommended. The purpose of an insulation blanket is to reduce the standby heat loss encountered with storage tank heaters. Your water heater meets or exceeds the National Appliance Energy Conservation Act standards with respect to insulation and standby loss requirements, making an insulation blanket unnecessary.

Connecting the Condensate Pump Overflow Shut Off Switch

1.Turn off power to the electrical wiring for the water heater at the circuit breaker/fuse box.

2.Locate the white 18 AWG wire loop behind the field wiring junction box. See Figure 8B.

3.Cut the loop and strip insulation off of the two ends.

4.Measure the distance from the field wiring junction box to the condensate pump, and cut two 18 AWG or larger wires to correct length and strip the insulation at both ends of each wire. See Figure 8B.
