Pump Wiring
*This feature is not available when using the Quick Con- nect Multi System feature.
Connecting the pump control wire
1.Leave enough slack so that the pump control wires will stay connected if the unit is removed from the wall.
2.Remove the front cover of the heater (4 screws).
3.Cut off the connector at the end of the pump control wires.
4.Wire the pump control wires through the wiring throughway and connect them to the wiring inside the pump (this will be the power supply for the pump, do not also connect 120 V to the pump).
If a large pump is being used (greater than 85W) use the voltage from these wires as the signal to close a normally open relay through which 120 V will be supplied directly from a wall circuit to the pump.
5.Replace the front cover.

Throughway Supplies Power for Circulating Pump
(Use a Relay for Larger Pumps)
Relay connection with larger pumps (>85 W)
1.Locate and prepare the pump control wires as described above.
2.Choose a suitable installation location for the relay where it will be protected from moisture.
3.Connect the pump control wires from the heater to the signal input on the relay.
4.Cut one of the electrical supply leads and wire it across the open terminals of the relay.
5.Secure all connections and replace the front cover of the heater.
