Step 11 Connecting the drain hose to
the outdoor unit
When heating, ice may accumulate. During the process
of defrosting, check if condensation draining is
adequate.
For adequate draining, do the following :
1 Insert the drain plug into the drain hole on the
underside of the outdoor unit.
2 Connect the drain hose to the drain plug.
3 Ensure that condensation draining is adequate.
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.
