HAND OVER
Teach the customer the operation and mainte-
nance procedures, using the operation manual
(air filter cleaning, temperature control, etc.).
CAUTION
After the confirmation of the above con-
ditions, 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
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 sources specifi-
cation.
(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, dam-
age on the contact point there of,
fuse breaking, disturbance to the nor-
mal function of a overload protection
device.
- Proper starting power is not given to
the compressor.
