Set Appliance State:
| Isolate Mains Power to appliance as per TOPs P4 |
Set Multimeter to AC Volts 
Gain access to PCB (use insulation mat as required)
| WARNING! - Mains voltage is expected during test follow TOPs P4 live testing procedure |
Measurement:
Test 1:
Measure the AC volts at pin 1 (red) at connector X1
on the PCB to a suitable earth point.
Voltage should be approximately 240V AC.
Test 2:
Measure the AC volts at pin 2 (blue at connector X1
on the PCB to a suitable earth point.
Voltage should be less than 15V AC.
Note:
This connection provides permanent 240V to both fan and pump.
