C Drain piping
• The drain hose should point downward for easy
drain flow.
• Do not make drain piping similar to diagrams
shown below.

2 Form the piping
A Form the piping by wrapping the connecting portion
of the indoor unit with insulation material and secure it
with narrow vinyl tape and wide vinyl tape.
• If you want to connect an additional drain hose, the end
of the drain outlet should be routed above the ground.
Secure the drain hose appropriately.
B In cases where the outdoor unit is installed below the
indoor unit perform the following.
• Tape the piping, drain hose and connecting cable from
down to up.
• Secure the tapped piping along the exterior wall using
saddle or equivalent.
B In cases where the outdoor unit is installed above the
indoor unit perform the following.
• Tape the piping and connecting cable from down to up.
• Secure the taped piping along the exterior wall. Form a
trap to prevent water entering the room.
• Fix the piping onto the wall by saddle or equivalent.
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 13)
7 Always install a Residual Current Device (RCD).
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 the
diagram below.
Checking the drainage and forming the piping
1 Check 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.

Note: 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 power supply
cord entry of the cabinet to the middle of the live pin
of the plug.
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 for 5.3kW, 6.2kW, 7.0kW,
and 8.8kW models, a power cord should be installed
according to the diagrams under "Connecting the cable
to the indoor unit" page 13.
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 (refer to table on
page 13) between the power source and the unit.
An isolation device to adequately disconnect all
supply lines must be fitted.
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 a
burn-out of the wires.
3 Specification of power source.
4 Confirm that electrical capacity of the installation
is sufficient.

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 colours.
3 Secure the cable with the cord clamp.
4 Wrap wires (conductors) that were not connected with
insulating tape so that they do no touch any electrical
or metal part.
