Checking Correct Earthing
Fixing the Unit in Position
If the power distribution circuit does not have an earth or the earth
does not comply with specifications, an earthing electrode must be
installed. The corresponding accessories are not supplied with the
air conditioner.

The outdoor unit must be installed on a rigid and stable base to
avoid any increase in the noise level and vibration, particularly if the
outdoor unit is to be installed close to a neighbour.
If it is to be installed in a location exposed to strong winds or at a height,
the unit must be fixed to an appropriate support (wall or ground).

1 Select an earthing electrode that complies with the specifications given in
the illustration opposite.
2 Determine a suitable location for the earthing electrode:
◆ 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 meters away from a lightening conductor earthing
electrode and its cable
➢ The earthing wire for the telephone line cannot be used to
earth the air conditioner.
3 Dig a hole of the size indicated in the illustration opposite, drive the
earthing electrode into position and cover the top of the electrode
with the excavated soil.
5 Carefully check the installation, by measuring the earthing resistance with
an earthing resistance tester. If the resistance is above the required
level(Example:100Ω), drive the earthing electrode deeper into the ground
or increase the number of earthing electrodes.
6 Connect the earthing wire to the earthing screw on the air conditioner.
4 Install a green/yellow insulated earthing wire (
Ø
1.6 mm, section 2 mm

or
greater):
◆ If the earthing wire is too short, connect an extension lead, soldering
the connection and wrapping it with insulating tape (do not bury the
soldered connection)
◆ Secure the earthing wire in position with staples
➢ If the earthing electrode is installed in an area of heavy traffic,
its wire must be connected securely.
1 Position the outdoor unit so that the air flow is directed towards the
outside, as indicated by the arrows on the top of the unit.
2 Attach the outdoor unit to the appropriate support using anchor bolts.
3 If the outdoor unit is exposed to strong winds, install shield plates around
the outdoor unit, so that the fan can operate correctly.
➢
Certainly fix up its rubber leg in order to prevent its vibration
and noise.
