1. AUTO MODE : In this mode, operation mode(COOL,
HEAT) is selected automatically by the room temperature
of initial operation.
∆T= -1°C, -2°C, 0°C, +1°C, +2°C
∆T is controlled by setting temperature up/down key of
remote control
2. COOL MODE : The unit operates according to the
difference between the setting and room temperature.
(18°C~30°C)
3. HEAT MODE : The unit operates according to the
difference between the setting and room tempera-
ture.(16°C~30°C)
*Prevention against cold wind : In order to prevent the
cool air from flowing out at the heat mode, the indoor fan
does not operate or operates very slowly in the
following cases. At this time, the indoor heat exchanger
will be preheating.
- For 3~5 minutes after the initial operation
- For deicing operation
- The operation of an indoor fan in accordance with
the temperature of an indoor heat exchanger
*High temperature release function : It is a function to
detect an outdoor overload by the sensor of an indoor
heat exchanger and to turn the outdoor fan or the
compressor ON/OFF for safety.
*Deice : Deicing operation is controlled by indoor unit's
heat exchanger temperature and accumulating time of
compressor's operation.
Deice ends by sensing of the processing time by deice
condition.
4. DRY MODE : Has 3 states, each determined by room
temperature.
The unit operates in DRY mode.
*Compressor ON/OFF Time is controlled compulsorily
(can not set up the fan speed, always breeze).
*Protective function : Low temperature release.
(Prevention against freeze)
5. TURBO MODE : This mode is available in AUTO, COOL,
HEAT, DRY, FAN MODE.
When this button is pressed at first, the air conditioner is
operated ''powerful'' state for 30 minutes regardless of the
set temperature, room temperature.
When this button is pressed again, or when the operating
time is 30 minutes, turbo operation mode is canceled and
returned to the previous mode.
*But, if you press the TURBO button in DRY or FAN
mode that is changed with AUTO mode automatically.
6. SLEEP MODE : Sleep mode is available only in COOL or
HEAT mode.
The operation will stop after 6 hours.
*In COOL mode : The setting temperature is
automatically raised by 1°C each 1hour When the
temperature has been raised by total of 2°C, that
temperature is maintained.
*In HEAT mode : The setting temperature is automatically
dropped by 1°C each 1hour.
When the temperature has been dropped by total of 2°C,
that temperature is maintained.
7. FAN SPEED : Manual (3 step), Auto (4 step)
Fan speed automatically varies depending on both the
difference between setting and the room temperature.
8. COMPULSORY OPERATION :
For operating the air conditioner without the remote
control.
*The air conditioner starts up in the most suitable mode
for the room temperature:

2-3 Installation
2-3-1 Before Installation
Keep the air conditioner drain hose outlet and inlet free from its surroundings.
In case of breakdown, keep the symmetry and fix it to prevent vibration.
The pipe length shall meet the standard as far as possible.
2-3-2 Installation Procedure
■Location
Install the product in an area to guarantee the best cooling effect, convenience of piping and electric work, and inexistence of
vibration or wind in the vicinity.
■Wall Drilling
Drill the wall downward in a diameter of 60 to 65mm.
■Fixing Indoor Unit & Outdoor Unit
Fix the air conditioner hard enough so that it can not fall to the ground. On the roadside, the outdoor unit shall be installed 2m
above ground and kept away from pedestrians to prevent direct exposure to hot wind.
■Pipe Spooling & Connecting
You shall cut the pipe straightly with a pipe cutter and grind all the burrs of the cut surface.
Pipe expansion may continue until the pipe surface becomes uneven or torn apart.
Be sure to use a torque wrench to tighten pipes or flare nuts.
■Leak Test
Put an inert gas like nitrogen in the outdoor unit pipe and put soap bubbles or other test liquids on the pipe surface for the leak test.
■Drain Hose Connecting
Install the drain hose downward to drain water naturally. Be sure to pour water into the hose to check if it drains well.
■Electric & Earth Work
Electric and earth work shall meet the "Electric Facility Technology Standard" and the "Internal Wire Regulation" of the Electric
Business Laws.
■Inspection & Trial Run
Upon completion of the tests, you shall make a trial run while you explain the main functions of the air conditioner to finish the
installation.

2-4-1 Air-Purge Procedure
1) Connect each assembly pipe to the appropriate
valve on the outdoor unit and tighten the flare nut.
3) Open the valve of the low pressure side of
manifold gauge counter-clockwise.
4) Purge the air from the system using vacuum
pump for about 30 minutes.
- After that, please recheck that pressure is
stabilization.
- Close the valve of the low pressure side of
manifold gauge clockwise.
- Remove the hose of the low pressure side
of manifold gauge.
7) Check for gas leakage.
- At this time, especially check for gas
leakage from the 3-Way valve’s stem nuts,
and from the service port cap.
2) Connect the charging hose of low pressure side
of manifold gauge to the packed valve having a
service port (3/8" Packed valve) as shown at the
figure.
5) Set valve cork of both liquid side and gas side of
packed valve to the open position.
6) Mount the valve stem nuts to the 2-Way and
3-Way valve. And mount the service port cap to
