CONNE CTING THE CABLE
BETWEEN INDOOR & OUTDOOR UNIT
Connec t the cable to the
outdoor unit
A
Remov e the control cov er fr om the unit by
loosening the screw .
Connect the wir es to the t erminals on the
control boar d individually.
B
Secure the cable on t o the control boar d with
the cord clamp .
C
Refix the contr ol cover t o the original
position with the scr ew.
D
Use a recogniz ed circuit br eaker 20A ( 12K,18K),
25A (24K) bet ween the pow er source
and the unit. A disconnecting device t o
adequately disconnect all supply lines must
be fitt ed.
After the confirmation of the above conditions, prepare the wiring as follows:
Never fail to have an individual power circuit specifically for the air conditioner. As for
the method of wiring, be guided by the circuit diagram pasted on the inside of control
cover.
The screw which fasten the wiring in the casing of electrical fittings are liable to come
loose from vibrations to which the unit is subjected during the course of
transportation. Check them and make sure that they are all tightly fastened. (If they
are loose, it could cause burn-out of the wires.)
Specification of power source.
Confirm that electrical capability is suf ficient.
The starting voltage is maintained at more than 90 percent of the rated
voltage marked on the name plate.
Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness. (Refer to page 16))
Always install an earth leakage circuit breaker in a wet or moist area.
The following would be caused by voltage drop.
The means for disconnection from a power supply shall be incorporated in the fixed
wiring and have an air gap contact separation of at least 3mm in each active(phase)
conductors.
Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance
of the normal function of the overload.
