Checking correct grounding
If the power distribution circuit does not have a grounding or the grounding does not comply with specifications, an
grounding electrode must be installed . The corresponding accessories are not supplied with the air conditioner .
1 .
Select an grounding electrode that complies with the specifications given
in the illustration.
2 .
Connect the flexible hose to the flexible hose port.

f
In damp hard soil rather than loose sandy or gravel soil that has a higher
grounding resistance .

f
Away from underground structures or facilities, such as gas pipes, water pipes,
telephone lines and underground cables .
X
f
At least two metres away from a lightening conductor grounding electrode
and its cable .
• The grounding wire for the telephone line cannot be used to ground
the air conditioner .
NOTE
3 .
Finish wrapping insulating tape around the rest of the pipes leading to the
outdoor unit.

If the grounding wire is too short, connect an extension lead, in a mechanical way and wrapping it with insulating tape
(do not bury the connection) .

Secure the grounding wire in position with staples .
• If the grounding electrode is installed in an area of heavy traffic, its wire must be connected securely .
NOTE
5 .
Carefully check the installation, by measuring the grounding resistance with a ground resistance tester. If the
resistance is above required level, drive the electrode deeper into the ground or increase the number of grounding
electrodes.
6 .
Connect the grounding wire to the electrical component box inside of the outdoor unit.
