Checking the earthing
If the power distribution circuit does not have a earthing or the earthing does not comply with 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 rather than 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.
• The earthing wire for the telephone line cannot be used to ground the air conditioner.

3.Finish wrapping insulating tape around the rest of the pipes leading to the outdoor unit.
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.
• If the earthing electrode is installed in an area with heavy traffic, its wire must be connected securely.
NOTE
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 or increase the number of earthing electrodes.
6.Connect the earthing wire to the electrical component box inside of the outdoor unit.
