7 After tube contraction work is completed, wrap it with
the insulation tape to finish.
CAUTION
∙ Make sure that the connection parts are not exposed
to outside.
∙ Be sure to use insulation tape and a contraction tube
made of approved reinforced insulating materials that
have the same level of withstand voltage with the power
cable. (Comply with the local regulations on extensions.)
WARNING
∙ In case of extending the electric wire, please DO NOT
use a round-shaped pressing socket.
– Incomplete wire connections can cause electric
shock or a fire.

Step 10 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.
