Installation
Disconnect all electric power to the water heater.
Remove the front cover panel on the water heater.
Install the recirculation pump on the return line
according to the pump manufacturer installation
instructions. Install a check valve in the return line as
shown in typical recirculation pump installation if one
is not integrated into the pump. See the bottom of page
65 for Typical Recirculation Pump Installation.
* Check valve is included in Rheem recirculation
pump kit.
The wire harness for the recirculation pump is bundled
with the wire harness from the control board. Find a
blue connector with a black and a white wire.
To connect to the pump, cut the blue connector, splice
the wires, and add a 4 amp fuse to the hot wire of the
pump. Rheem recirculation pump kit includes a molex
connector and a 4 amp fuse so splicing wires is not
required.
Connect the ground wire from the pump to a screw at
the base of the water heater cabinet.
NOTICE:
Follow any applicable electrical code and the pump
manufacture installation instruction referring to the
Pump Electrical Connection Diagram in Step 5 of these
instructions.
Find DIP Switch 2 in the top-right portion of the control
board. The switch labeled “DIP 2” is the bottom switch.
