Note: This sensor is replaced as a set with the
Discharge Temperature Sensor.
1. Remove front panel.
2. Push and release Off button.
3. Remove 1 plastic bolt and the reservoir cover.
4. Locate water temperature sensor (inserted into
pump discharge hose).
5. Pull out to remove.

(see next).
8. Reverse to reassemble.
Discharge Line Temperature Sensor
1. Remove front panel, push and release the Off
button.
2. Locate discharge line sensor. It is attached to
the discharge line of the compressor, 6" from the
compressor discharge port.
3. Unwrap the insulation and un-snap the clip

4. Trace the sensor wires back to the controller,
they are plugged into #5 with the water
temperature sensor, and must be replaced with it.
5. Reverse to replace, be sure that the discharge
line sensor is 6" up from the compressor discharge
port. Be sure to re-wrap the insulation.
Note: Route wires so they do NOT contact the
discharge line.
The sensor for the Discharge line is marked
