TEST RUNNING
CAUTION
After the confirmation of the above
conditions, 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
burnout of the wires.)
• Specification of power source.
• Confirm that electrical capacity is
sufficient.
• 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
specification. (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
different Indoor units combinations as
shown below.
