1) Connecting the piping to the Outdoor
unit
1. Align the center of the piping and sufficiently
tighten the flare nut with fingers.
2. Finally, tighten the flare nut with torque wrench
until the wrench clicks.
• When tightening the flare nut with torque wrench,
ensure the direction for tightening follows the arrow
on the wrench.
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 pasted on the inside of control box cover.
2) Provide a circuit breaker switch between power source and the unit.
3) 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.)
4) Specification of power source.
5) Confirm that electrical capacity is sufficient.
6) See to it 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 specification.
(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 there of, fuse breaking, disturbance to the nor-
mal function of a overload protection device.
• Proper starting power is not given to the compressor.

(clamper).
3. Refix the cover control to the original position with the
screw.
4. Use a recognized circuit breaker 16A between the power
source and the unit. A disconnection device to adequately
disconnect all supply lines must be fitted.
