If the powerdistribution circuit does not have a earthing or
the earthing does not complywith specifications, an earthing
electrode must be installed. The corresponding accessories
are not supplied with the air conditioner.
1 Select an earthing electrode that complies with the
specifications given in the illustration.
2 Connect the flexible hose to the flexible hose port.
• In damp hard soil ratherthan loose sandy or gravel
soil that has a higher earthing resistance.
• Away from underground structures or facilities,
such as gas pipes, water pipes, telephone lines and
underground cables.
• At least two metres away from a lightening
conductor earthing electrode and its cable.

4 Install a green/yellow coloured earthing wire:
• If the earthing wire is too short, connect an
extension lead in a mechanical way and wrap it with
insulating tape (do not bury the connection).
• Secure the earthing wire in position with staples.
NOTE
• If the earthing electrode is installed in an area with
heavy traffic, its wire must be connected securely.
5 Carefully check the installation by measuring the earthing
resistance with a earth resistance tester. If the resistance
is above the required level, drive the electrode deeper into
the ground orincrease the numberof earthing electrodes.
6 Connect the earthing wire to the electrical component
box inside of the outdoor unit.
Step 11 Performing gas leakage test
Use nitrogen gas at a pressure range between 0.2 and 4.1 MPa
when testing the gas leakage. If you apply pressure at over 4.1
MPa, the refrigerant pipes may be damaged.
