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.
ffIn damp hard soil rather than loose sandy or gravel soil that has a higher
grounding resistance.
ffAway from underground structures or facilities, such as gas pipes, water
pipes, telephone lines and underground cables.
ffAt least two metres away from a lightening conductor grounding electrode
and its cable
