1. With all power switched off, disconnect the three wires from the compressor, making sure
to note down which wire goes to what terminal, now connect the 3 probes from the Inverter
Checker outputs labelled 1, 2, and 3 to the end of compressor wires (as shown below).
2. With the three wire connections safely made from the outdoor inverter printed circuit board
to the Inverter Checker, place the module on a dry surface, preferably in the shade, where
the lights can be seen through the windows in the facia panel. Now switch the power back
on and operate the system. Please note that most units will have a time delay/cycle
protector, so you may have to wait 3 to 5 minutes for the system to start operating, this will
depend on make and model of your system.
3. If the inverter outputs are "Good" then all six lights will illuminate, showing red, yellow and
blue. If there is a problem with the output (power) board, or with the printed circuit board
then one or more of the lights will not be lit.
NOTE: The inverter boards from some manufacturers incorporate a safety cut-out which stops
the inverter after a few seconds if the compressor is not connected. In these cases the lights
on the Inverter Checker will only light for a few seconds, but provided all six lights turn on then
the inverter printed circuit board is probably ok. A second test, with both the compressor and
the Inverter Checker connected, should then provide further confirmation.
