CAUTION
!
According to the confirmation of the above
conditions, prepare the wiring as follows.
1
Never fail to have an individual power
circuit specifically for the air condition-
er. As for the method of wiring, be guid-
ed 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 become loose from vibrations to
which the unit is subjected during the
transportation. Check them and make
sure that They all are 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 suffi-
cient.
5
See that the starting voltage is main-
tained 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 specifi-
cation.
(Particularly note the relation between
cable length and thickness.
7
Always install an earth leakage circuit
breaker in a wet or moist area.
8
The following would be caused by volt-
age drop.
- Vibration of a magnetic switch, which
will damage the contact point, fuse
breaking, disturbance of the normal
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.

Checking the Drainage

To check the drainage.
1
Pour a glass of water on the evaporator.
2
Ensure the water flows through the drain
hose of the indoor unit without any leakage
and goes out the drain exit.
* The feature can be changed according to the
type of model.
