those of the indoor unit.)
1. Lift the front panel up and remove the
window cover from the indoor unit by
loosening the screw.
2. Connect wires to the Indoor Unit terminals
from the Outdoor Unit as identified by their
colors.
3. Secure the cable with the cord clamp.
4. Wrap wires (conductors) that were not
connected with insulating tape so that they do
not touch any electrical or metal parts.
Notes:
Wrong wire connection may cause some
electrical parts to malfunction.
The length of the power supply cord should
be at least 1.8m measured from the power
supply cord entry of the cabinet to the middle
of the live pin of the plug.
2.5.2 Connect the cable to the outdoor unit
2.5.2.1 Remove the control cover from the unit by
loosening the screw. Connect the wires to the
terminals on the control board individually.
2.5.2.2 Secure the cable onto the control board
with the cord clamp.
2.5.2.3 Re-fix the control cover to the original
position with the screw.
2.5.2.4 Use a recognized circuit breaker (Refer to
table on page 11.) between the power source and
the unit. An isolation device to adequately
disconnect all supply lines must be fitted.
CAUTIONS:
After confirming the above conditions, prepare the
wiring as follows:
1) Never fail to have an individual power circuit
Service manual for Electrolux split Series
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 screws which fasten the wiring in the
casing of electrical fittings may 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 of the
installation is sufficient.
5) Ensure 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 11.)
7) Always install a Residual Current Device
(RCD) in wet or moist area.
8) The following may be caused by voltage drop.
Vibration of a contactor, which will damage
the contact point, fuse blowing, 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)
conductor.
If a power plug is not to be used, provide a Circuit
Breaker/Fuse between power source and the unit
as shown in adjacent diagram.
