8 WIRING
The appliance shall be installed in accordance with
national wiring regulations.
The air conditioner should use separate power supply
with rated voltage.
The external power supply to the air conditioner should
be grounded, which is linked to the ground wiring of the
indoor and outdoor unit.
The wiring work should be done by qualified persons
according to wiring diagram.
A circuit breaker and a residual current device (RCD) with
above 10mA rating shall be installed in the power circuit
according to the national rule.
Be sure to locate the power wiring and the signal wring
well to avoid cross-disturbance.
Do not turn on the power until you have confirmed
proper wiring.
The power cord type is H07RN-F.
The power connection for the air conditioner has to be
done at the main power distribution. The distribution has
to be of a low impedance, normally the required
impedance reaches at a 32A fusing point.
No other equipment has to be connected with this power
line.
For detailed installation acceptance please refer to your
power supplier, if restrictions do apply for products like

Please use heat-resistant materials as heat insulation materials
of the air-side pipe. (e.g., EPT)
Cover heat insulation materials separately at the liquid side and
the air side. Moreover, perform heat insulation thoroughly for the
air-side pipes of the indoor unit, and prevent water from dripping
outside the unit.
After applying the auxiliary heat insulation materials, use
vinylresin tape to seal it lest water leak.
