7.4. Outdoor unit (Fig. 7-8)
• Connect cable from the indoor unit correctly on the terminal-block.
• Use the same terminal block and polarity as is used with the indoor unit.
• For aftercare maintenance, give extra length to connecting cable.
• Both end of connecting cable (extension wire) are peeled off. When too long,
or connected by cutting off the middle, peel off power supply cable to the size
given in the figure.
• Be careful not to contact connecting cable with piping.
Caution:
• Use care not to make mis-wiring. (Fig. 7-9)
• Firmly tighten the terminal screws to prevent them from loosening.
• After tightening, pull the wires lightly to confirm that they do not move.
Warning:
• Be sure to attach the service panel of the outdoor unit securely. If it is not
attached correctly, it could result in a fire or an electric shock due to dust,
water, etc.
• Tighten terminal screws securely.
• Wiring should be done so that the power lines are not subject to tension.
Otherwise, heat may be generated or fire may occur.

M Indoor unit
N Earth terminal
O Earth cable
P 850 mm or more
Q Safety net (procured locally)
Notes:
• The fan and motor are dangerous if handled during operation. For this
reason, be sure to install the indoor unit at least 850mm from the air intake
grill G.
If it is not possible to put more than 850 mm of distance between the air
intake grill and the indoor unit, install the safety net Q (locally procured).
• Connect the main body of the air conditioner and the duct so that their
potentials are equal.
• Connect an earth cable O from the air outlet flange C to the earth terminal
N. Then, connect another earth cable O from the earth terminal N to the
air outlet duct D.
• Be sure to install an air filter (procure locally) and an air outlet duct.
