11. WIRING
Attaching wiring
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.
A leakage protector should be installed according to the National
Standard concerning electrical appliance.
Be sure to locate the power wiring and the signal wring well to
avoid cross-disturbance and their contact with connecting pipe
or stop value body.
The wiring attached to this air conditioner is 10m long. Be sure
to prolong it with wiring of the same type and proper length
if necessary. Generally, do not twist two wiring together unless
the joint is soldered well and covered with insulator tape.
Do not turn on the power until you have checked carefully after
wiring.
