7. WIRING
Specified power cables should be used. Do not apply any
pressure on the terminals used to connect.
Improper connection may cause fire.
Grounding must be properly done.
The grounding wire should be away from gas pipes, water
pipes, telephone, lightening rods or other grounding wires.
Improper grounding may cause electric shock.
Electric Wiring must be done by professionals. Use a
separate circuit according to national regulations.
If the wiring capacity is not enough, electric shock or fire may
occur.
CAUTION
1. Be sure to Install Current Leakage Protection Switch, Or
electric shock may occur.
2. Power cord is to be selected according to national
regulations.
3. an all-pole disconnection device which has at least 3mm
separation distance in all pole and a residual current
device(RCD)with the rating of above 10mA shall be
incorporated in the fixed wiring according to the national rule.
4. Outdoor unit power cord should be selected and connected
according to the outdoor unit installation manual.
5. Wiring should be away from high temperature components,
or the insulation layer of the wires may melt down.
6. Use wire clamp to fix the wires and terminal block after
connection.
7. Control wire should be wrapped together with heat insulated
refrigerant pipes.
8. Connect the indoor unit to power only after the refrigerant
has been vacuumed.
9. Don’t connect the power wire to the signal wire connection
end.
7.1 The specification of power
CAUTION
A disconnection device having an air gap contact separation
in all active conductors should be incorporated in the fixed
wiring according to the National Wiring Regulation.
