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.
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
To
earthing resistance
earthing
screw
 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.
4
Install a green/yellow insulated earthing wire (Ø1.6 mm, section 2 mm
 If the earthing wire is too short, connect an extension lead, soldering the connec
tion 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.
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.
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
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.
Y 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.

OUTDOOR UNIT INSTALLED ON THE WALL BY RACK
- Ensure the wall will be able to suspend the weight of rack and outdoor unit;
- Install the rack close to the colum as much as possible;
- Install proper grommet in order to reduce noise and residual vibration trans-
ferred by outoor unit towards wall.
Certainly fix up its rubber leg in order to prevent its vibration
and noise.
