Testing (Turn on Power to AC Unit):
Switch:
1. Once installed and the power is turned on and the
COMPRESSOR IS RUNNING
, the CPU will display a flashing green LED. If the green
LED does not come on, reverse the switch leads.
2. Test the sensor position: Test the sensor position by filling the auxiliary pan with water. Adjust the sensor so that the switch will
activate at a preferred water depth but before the pan overflows.
3. Test the switch by shorting across the probes with your finger or water. If wired correctly, the unit will stop and the red LED will
come on after 5 seconds. When released, after 5 seconds the red LED will go off, the green and amber LEDs will come on and the AC
unit will restart. If the switch does not cycle, try shorting across the probes with a metallic conductor or water. To turn off amber light,
see manual history reset tag on CPU wire.
The device must be installed strictly in accordance with manufacturer’s instructions (to ensure proper operation) and in
