Operation Details
(1) The function of main control
1. Time Delay Safety Control
•3min.; The compressor operation is delayed for 3 minutes to balance the pressure of cycle.
(Protection of compressor)
•5sec.;
The indoor fan is delayed for 5 seconds, when operating initially, to prevent noises occurred by the vertical
louver and wind.
2. Airflow Direction Control
•This function is to swing the vertical louver up and down automatically and to set it at a fixed position.
•The procedure is as the following.
1st ; Press the ON/OFF Button to operate the unit.
2nd ; Press the Airflow Direction Control Button to swing the vertical louver up and down automatically.
3nd ; Repress the Airflow Direction Control Button to set the vertical louver at a fixed position.
3. Cooling Mode Operation
•When selecting the Cooling( ) Mode Operation, the unit will operate according to the setting by the
remote controller and the operation diagram is shown below.

•When the room temperature rises over the compressor ON temperature, the operation mode is switched to
the Cooling operation.
•When the room temperature falls between the compressor ON temperature and OFF temperature, the opera-
tion mode is switched to the Soft Dry Operation.

1) Selection of the best location
1. Indoor unit.
•There should not be any heat source or steam
near the unit.
•There should not be any obstacles to prevent the
air circulation.
•A place where air circulation in the room will be
good.
•A place where drainage can be easily obtained.
•A Place where noise prevention is taken into con-
sideration.
•Do not install the unit near the door way.
•Ensure the spaces indicated by arrows from the
wall, ceiling, fance, or other obstacles.
2. Outdoor unit.
•If an awning is built over the unit to prevent direct
sunlight or rain exposure, be careful that heat
radiation from the condenser is not restricted.
•There should not be any animals or plants which
could be affected by hot air discharged.
•Ensure the spaces indicated by arrows from the
wall, ceiling, fance, or other obstacles.

2) Indoor unit installation
The mounting wall should be strong and solid
enough to prevent 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 horizon-tally
by aligning the marking-off line with using 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.

1) Preparation of pipings
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 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
leakage.
3. Flaring the pipes.
•Insert the flare nuts, mounted on the connection
ports of both indoor and outdoor unit, onto the
copper pipes. Some gas may leak, when the flare
nuts are removed from the indoor unit, 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.

2. Piping and Drainage of indoor unit

2) Connection of Pipings
1. Remove the installation plate.
•Pull the two ‘∆’marked portion of bottom of the
chassis and pull the installation plate out of
chassis.
2. Route the drain hose and the indoor tubing.
3. Connect the pipings and the indoor tubing, and
drain hose and drain pipe.
•Do not connect the cable to the indoor unit.
•Wrap the insulation material around the connect-
ing portion.
•Glue up the connection portion of drain hose and
drain pipe.
4. Insert the pipings, the connecting cables and
the drain pipe throught the piping hole on the
wall.

drain hose altogether.
•Make a small loop for easy connection later.
6. Wrap the tubing, the drain hose and the
connecting cable.
7. Indoor unit installation
•Hook the indoor unit onto the upper portion of
installation plate.(Engage the two hooks of the
rear top of the indoor unit with the upper edge of
the installation plate.)
Ensure the hooks are properly seated on teh
installation plate by moving it in left and right.
CAUTION : Take care to arrange the pipings, drain
hose and cables as the feature for
inserting it into the indoor unit and
mount the indoor unit on the installa-
tion plate.
