INSTALLATION
22
CAUTION
!
According to the confirmation of the above
conditions, prepare the wiring as follows.
1
Never fail to have an individual power cir-
cuit 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.)
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 specifica-
tion. (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 3 mm in each
active(phase) conductors.
10
Open the terminal cover block before
connecting the indoor side wire.
Electrical Wiring
1
All wiring must comply with LOCAL REG-
ULATIONS.
2
Select a power source that is capable of
supplying the current required by the air
conditioner.
3
Feed the power source to the unit via a
distribution switch board designed for this
purpose.
4
The terminal screws inside the control box
may be loose due to vibration during trans-
port.
Check the screws for loose connection.
(Running the air conditioner with loose
connection can overload and damage elec-
trical components.)
5
Always ground the air conditioner with a
grounding wire and connector to meet the
LOCAL REGULATION.

!
• The circuit diagram is not subject to
change without notice.
• Be sure to connect wires according to
the wiring diagram.
• Connect the wires firmly, so that not to
be pulled out easily.
• Connect the wires according to color
codes by referring the wiring diagram.
