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.
NOTE
• 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.
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 or increase the
number of earthing electrodes.
6 Connect the earthing wire to the electrical component
box inside of the outdoor unit.

• 1 phase power supply : L, N
2 Check the indoor unit.
a Check that you have connected the power and
communication cables correctly. (If the power
cable and communication cables one mixed up or
