8. WIRING
CAUTION
The appliance shall be installed in accordance with
natioanl wiring regualtions.
The air conditioner should use separate power supply
with rated voltage.
The external power supply to the air conditioner should
have ground wiring, which is linked to the ground wiring
of the indoor and outdoor unit.
The wiring work should be done by qualified persons
according to circuit drawing.
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.
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 checked
carefully after wiring.
NOTE
Remark per EMC Directive 2004/108/EC
For to prevent flicker impressions during the start of the
compressor (technical process) ,following installation
conditions do apply.
The power connection for the air conditioner has to be
done at the main power distribution. The impedance of
the distribution has to be low impedance.
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
washing machines, air conditioners or electrical ovens.
The temperature of refrigerant circuit will be high, please
keep the interconnection cable away from the copper
tube.

Ventilate the air if there was any refrigerant leakage during
installation.Leaked refrigerant will generate poisonous gas if
meeting fire.
Make sure there is no refrigerant leakage after installation.
Leaked refrigerant will generate poisonous gas if meeting fire.

Refrigerant Volume to Be Added
Refrigerant Volume to be added is calculated according to
Outdoor Unit Installation Manual .
Be save to add refrigerant measuring by a scale.
If refrigerant volume added is inadequate (too much or
insufficient),the compressor malfunction will be caused.Be
sure to calculate the refrigerant volume carefully.
The service man should note down the piping length and
refrigerant volume added on the nameplate, which is on the
Electric Control Box Cover of outdoor unit for to diagnose the
compressor when compressor malfunction occurs.
