After the confirmation of the above condi-
tions, prepare the wiring as follows:
• Never fail to have an individual power
specialized for the air conditioner. As for
the method of wiring, be guided by the
circuit diagram pasted on the inside of
control box cover.
• Provide a circuit breaker switch between
power source and the unit.
• 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 give rise to burn-
out of the wires.)
• Specification of power source.
• Confirm that electrical capacity is suffi-
cient.
• Be sure that the starting voltage is main-
tained 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 sources specifica-
tion.
(Particularly note the relation between
cable length and thickness.)
• Never fail to equip a leakage breaker
where it is wet or moist.
• The following troubles would be caused
by voltage drop-down.
- Vibration of a magnetic switch, damage
on the contact point there of, fuse
breaking, disturbance to the normal
function of a overload protection
device.
- Proper starting power is not given to
the compressor.
• Use only 1 remote-controller contained
in indoor unit, when you combine to use
both cassette type indoor unit and differ-
ent Indoor units combinations as shown
