When installing insulation in places and conditions
below, use the same insulation that is used for
high humidity conditions.
<Geological condition>
– High humidity places such as shoreline, hot
spring, near lake or river, and ridge (when the
part of the building is covered by earth and
sand.)
<Operation purpose condition>
– Restaurant ceiling, sauna, swimming pool etc.
– <Building construction condition>
– The ceiling frequently exposed to moisture
and cooling is not covered.
– e.g. The pipe installed at a corridor of a
dormitory and studio or near an exit that
opens and closes frequently.
– The place where the pipe is installed is highly
humid due to the lack of ventilation system.
Step 13 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 14 Performing final check and
trial operation
1
Check the power supply between the outdoor unit
and the auxiliary circuit breaker.

1 phase power supply: L, N
•
3 phases power supply: R, S, T, N
