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
sepaaration 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
