Installation
CAUTION :
After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power specialized for the air conditioner.
As for the method of wiring, be guided by the circuit diagram posted on the
inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) The screws which fasten the wiring in the casing of electrical fittings are li-
able 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 give rise to burn-out of the wires.)
4) Specification of power source
5) Confirm that electrical capacity is sufficient.
6) Be sure that the starting voltage is maintained at more than 90 percent of the
rated voltage marked on the name plate.
7) Confirm that the cable thickness is as specified in the power sources specifi-
cation. (Particularly note the relation between cable length and thickness.)
8) Never fail to equip a leakage breaker where it is wet or moist.
9) The following troubles would be caused by voltage drop-down.
• Vibration of a magnetic switch, damage on the contact point, fuse breaking, dis-
turbance by the normal function of an overload protection device.
• Proper starting power is not given to the compressor.
