Checking Correct Earthing; Fixing The Unit In Position - Samsung AJ***JCJ2CH Installation Manual

A C hecking correct earthing
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 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.
4. Install a green/yellow insulated earthing wire (Ø0.06inch(1.6 mm), section
0.003inch²(2 mm²) or greater):
◆ 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.

Fixing the unit in position

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.
2. Attach the outdoor unit to the appropriate support using anchor bolts.
◆ The earthing wire for the telephone line cannot be used to earth the air
conditioner.
3. DIf 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.
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
transferred by outoor unit towards wall.
