Rooftop Installations:
If the outdoor unit is installed on a roof structure, be
sure to level the unit. Ensure the roof structure and
anchoring method are adequate for the unit location.
Consult local codes regarding rooftop mounting.
If the outdoor unit is installed on root structures or walls,
this may result in excessive noise and vibration, and
maybe also classed as non serviceable installation.

Connect the cable to the indoor unit by connect-
ing the wires to the terminals on the control
board individually according to the outdoor unit
connection.(Ensure that the color of the wires of the
outdoor unit and the terminal No. are the same as
those of the indoor unit.)

After the confirmation of the above conditions, prepare the wiring as follows:
1) Never fail to have an individual power circuit specifically for the air conditioner. As for the method
of wiring, be guided by the circuit diagram posted on the inside of control cover.
2) 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 cause burn-out of the wires.)
sure that they are all tightly fastened. (If they are loose, it could cause burn-out of the wires.)
3) Specification of power source.
4) Confirm that electrical capacity is sufficient.
5) See to that the starting voltage is maintained at more than 90 percent of the rated voltage marked
on the name plate.
6) Confirm that the cable thickness is as specified in the power source specification.
(Particularly note the relation between cable length and thickness. (Refer to page 28))
7) Always install an earth leakage circuit breaker in a wet or moist area.
8) The following would be caused by voltage drop.
• Vibration of a magnetic switch, which will damage the contact point, fuse breaking, disturbance of the nor-
mal function of the overload.
9) The means for disconnection from a power supply shall be incorporated in the fixed wiring and
have an air gap contact separation of at least 3mm in each active(phase) conductors.
