caution
After confirming the above conditions,
prepare the wiring as follows:
• The screws which fasten the wiring to
the terminal block may come loose from
vibrations during transportation.
• Check and make sure all screws are well
fixed. Otherwise, it could cause burn-out
of the wires.
• Be sure the circuit capacity is sufficient.
• Ensure the starting voltage is maintained
at over 90% of the rated voltage marked
on the nameplate.
• Confirm that the cable thickness is
as specified in the power source
specification.
• Always install a Residual Current Device
(RCD) in wet or moist area.
• 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.
• 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.
step 10: Checking the Drainage
A.
Open and lift the indoor unit front panel.
• Hold the lower part of the left and right sides
of the panel, pull it against you and lift it stops
with a full support from the bracket.

B. Check the drainage
• Carefully pour a glass of water on the
evaporator.
• Ensure the water flows through the drain
hose of the indoor unit without any leakage
and goes out the drain exit.
C. Drain piping
• The drain hose should
point downward for
easy drain flow.
• Do not place drain piping as indicated below:
