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
f
grounding resistance .
f Away from underground structures or facilities, such as gas pipes, water
f
pipes, telephone lines and underground cables .
f At least two metres away from a lightening conductor grounding electrode
f
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 .
4 . Install a green/yellow coloured grounding wire :
f If the grounding wire is too short, connect an extension lead, in a mechanical way and wrapping it with insulating tape
f
(do not bury the connection) .
f Secure the grounding wire in position with staples .
f
• 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 .
