Settlement of Outdoor Unit
• Anchor the outdoor unit with a bolt and nut
(ø10cm) tightly and horizontally on a concrete or
rigid mount.
• When installing on the wall, roof or rooftop, anchor
the mounting base securely with a nail or wire
assuming the influence of wind and earthquake.
• In the case when the vibration of the unit is con-
veyed to the house, settle the unit with an anti-
vibration rubber.
2) Evaluation of the performance
1. Measure the temperature of the intake and dis-
charge air.
2. Ensure the difference between the intake tem-
perature and the discharge one is more than 8
°C(Cooling) or reversely (Heating).
1) Connection of power supply
1. Connect the power supply cord to the inde-
pendent power supply.
• Circuitbreaker is required.
2. Prepare the remote controller.
• Insert two batteries provided.
Remove the battery cover from the remote con-
troller.
• Slide the cover according to the arrow direction.

2) Indoor Unit Installation
The mounting wall should be strong and solid enough
to protect it from the vibration.
1.Mount the installation plate on the wall with four
Type "A" screws.
(if mounting the unit on the concrete wall, consider
using anchor bolts.)
• Always mount the Installation plate horizontally by
aligning the marking-off line by means of the
thread and a level.
2. Drill the piping hole with 70mm dia. holecore
drill.
• Line according to the arrows marked on lower the
left and the right side of the Installation Plate.
The meeting point of the extended line is the cen-
ter of the hole.
• Drill the Piping hole at either the right or the left
and the hole should be slightly slanted to the out-
door side.

2. Piping and Drainage of Indoor Unit
1) Preparation of Piping
1. Cut the pipes and the cable.
• Use the accessory piping kit or the pipes pur-
chased locally.
• Measure the distance between the indoor and the
outdoor unit.
• Cut the pipes a little longer than measured dis-
tance.
• Cut the cable 1.5m longer than the length of the
pipe.
2. Remove burrs.
• Remove burrs from cut edges of pipes.
• Turn the pipe end toward down to avoid the metal
powder entering the pipe.
Caution:
If burrs are not removed, they may cause a gas leak-
age.
3. Flaring the pipes.
• Insert the flare nuts, mounted on the connection
ports of both indoor and outdoor unit, onto the
copper pipes. (When the flare nuts are removed
from the indoor unit.) Some gas may leak, as
some gas is charged to prevent the inside of the
pipe from rusting.
• Fit the copper pipe end into the Bar of flare tool
about 0~1.0mm higher. (See illustration)
• Flare the pipe ends.
4. Tape the flaring portion to protect it from the
dust or damages.

After the flare part comes into contact with the connec-
tors, carefully check the flare finish.
