Service precautions
Caution when performing service to inverter equipment
■
Please note that some sections of the electric component box
are extremely hot.
■
In order to prevent damage to the PCB, first eliminate static
electricity by touching a metal part (e.g. stop valve) with your
hand. Then pull out the connector.
■
After measuring the residual voltage, pull out the outdoor fan
connector.
■
Make sure you do not touch a conductive section.
■
The outdoor fan may rotate due to strong backblow wind,
causing the capacitor to charge. This may result in an electric
shock.
After maintenance, make sure the outdoor fan connector is
connected again. Otherwise, the unit may break down.

WARNING: ELECTRIC SHOCK
DANGER
■
Do not touch live parts for 10 minutes after the power
supply is turned off because of high voltage risk.
■
Make sure that the power supply is turned off before
performing the maintenance work. The heater of the
compressor may operate even in stop mode.
Play it safe!
Touch a metal part by hand (such as the stop valve) in
order to eliminate static electricity and to protect the PCB
before performing service.
