Checking the drainage
A: To remove the front panel from the indoor unit.
• Pull the lower left and right sides of the grille towards
you and lift it up.

B: To check the drainage
• 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 make drain piping similar to diagrams shown
below on the right.

8 The following may be caused by voltage drop.
Vibration of a conductor, which will damage the contact
point, fuse blowing, disturbance of the normal function
of the overload.
9 The means for disconnection of 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 the
diagram below.

caution
After confirming the above conditions, prepare the wiring
as follows:
1 never fail to have an individual power circuit specifically
for the air conditioner. As for the method of wiring,
be guided by the circuit diagram posted on the inside
of the 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 14).
7 Always install a Residual Current Device (RCD) in wet
or moist area.
Length of the power supply cord should be at least 1.8m.
Measure from the power supply cord entry of the cabinet
to the middle of the live pin of the plug.

caution
Ensure that all electrical work complies with relevant
Standards and Supply Authority Service Rules.
An individual branch Circuit Breaker/Fuse must be used with
this Air Conditioner. See the table for electrical requirements.
Note:
• Power Source and Power Cord specifications must
comply with requirements above.
• Circuit Breaker or Fuse specified in this manual must be
installed in the power supply circuit.
• For your safety and protection, this unit is earthed
through the power cord plug when plugged into a
matching wall receptacle.
• Do not connect two power cords together to supply
power to the air conditioner.
• Do not extend the power cable conductors by cutting.
Connect the cable to the outdoor unit
A: Remove the control cover from the unit by loosening
the screw.
Connect the wires to the terminals on the control
board individually.
B: Secure the cable onto the control board with the
cord clamp.
C: Refix the control cover to the original position with
the screw.
D: Use a recognised circuit breaker (See page 17) between
the power source and the unit. An isolation device to
adequately disconnect all supply lines must be fitted.
