Connecting the Condensate Pump
Overow 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 9B.
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 9B.
5. 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.
9. 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.
10. The heat pump should turn off and the error code
“CONDENSATE DRAIN ALARM “will appear on the
user interface screen.
11. Plug the condensate pump in and verify that the pump
operates and pumps the water out of the condensate
reservoir.
12. The error on the user interface should clear and the
heat pump should operate after 8 minutes.
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.
