Installation Procedure
Installation Procedure
Step 12 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.
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.
Step 13 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.

1 Connect the charging hose of low pressure side of
manifold gauge to the packed valve having a service port
as shown at the figure.
NOTE
The designs and shape are subject to change according
to the model.
2 Open the valve of the low pressure side (A) of the
manifold gauge anticlockwise.
3 Connect the manifold gauge to the nitrogen gas.
4 Apply nitrogen gas.
5 Check the change of pressure with a pressure regulator.
6 Check the gas leakage at the connection part or brazed
part by using soap water.
7 Open the manifold gauge to discharge nitrogen.
