Remarks
Connected with simple remote controller.
Check the existing wires for damage to insulation by measuring the resistance between the lead and the ground with a 500V
ohmmeter. If the insulation resistance is less than 100 MΩ, replace the wires.
Disconnect all controllers before measuring insulation resistance to avoid controller damage.
Note: Disconnect the system controller before starting a refrigerant oil recovery operation, if one is connected.
Reconnect the system controller after the completion of the refrigerant oil recovery operation.
