2-3 Installation
2-3-1 Before Installation
Keep the air conditioner outlet and inlet free from its surroundings.
In case of installation, 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.
■Wall Drilling
Drill the wall downward in a diameter of 60 to 65mm.
■Fixing Indoor Unit & Outdoor Unit
Fix the air conditioner indoor unit securely to the wall. Secure the outdoor unit in a suitable position.
■Pipe Spooling & Connecting
You shall cut the pipe 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 Installation Diagram of Indoor Unit and Outdoor Unit
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
stabilized.
- 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
3-Way valve.

1) Purge air(for new installation only).
3) Connect the tank to refill with refrigerant.
4) Set the unit to cool operation mode.
7) Stop operation of the air conditioner.
9) Close the cap of each valve.
2) Turn the 3-Way valve clockwise to close,
connect the pressure gauge (low pressure side) to
the service valve, and open the 3-Way valve
again.
5) Check the pressure indicated by the pressure
gauge(low pressure side).
* Standard pressure is should be 9.0~10.0kg/cm2
in a regular, high operation mode.
6) Open the refrigerant tank and fill with refrigerant
until the rated pressure is reached.
* It is recommended not to pour the refrigerant
in too quickly, but gradually while operating a
pressure valve.
8) Close the 3-Way valve, disconnect the
pressure gauge, and open the 3-Way valve
again.

Operating Instructions & Installation
2-4-3 "Pump down" Procedure
Pump down will be carried out when an evaporator is replaced or when the unit is relocated in another area.
3-Way Valve
2-Way Valve
1) Remove the caps from the 3-Way valve and the
3-Way valve.
3) Set the unit to cool operation mode.
(Check if the compressor is operating.)
4) Turn the 3-Way valve clockwise to close.
7) Close the cap of each valve.
2) Turn the 3-Way valve clockwise to close and
connect a pressure gauge (low pressure side)
to the service valve, and open the 3-Way valve
again.
5) When the pressure gauge indicates "0" turn the
3-Way valve clockwise to close.
6) Stop operation of the air conditioner.
Relocation of the air conditioner
• Refer to this procedure when the unit is relocated.
• Carry out the pump down procedure (refer to the details of 'pump down').
• Remove the power cord.
• Disconnect the assembly cable from the indoor and outdoor units.
• Remove the flare nut connecting the indoor unit and the pipe.
• At this time, cover the pipe of the indoor unit and the other pipe using a cap or vinyl plug to avoid foreign
material entering.
• Disconnect the pipe connected to the outdoor unit.
At this time, cover the valve of the outdoor unit and the other pipe using a cap or vinyl plug to avoid foreign
material entering.
• Make sure you do not bend the connection pipes in the middle and store together with the cables.
• Move the indoor and outdoor units to a new location.
• Remove the mounting plate for the indoor unit and move it to a new location.

The airconditioner may not operate properly if the voltage is out of this range.
2. Is the link cable linking the indoor unit and the outdoor unit linked properly?
The indoor unit and the outdoor unit shall be linked by 5 cables.
Check the terminals if the indoor unit and outdoor unit are properly linked by the same number of cables.
Otherwise the airconditioner may not operate properly.

Operation of air conditioner Explanation
It indicates power is on. The LED stops blinking if the opera-
tion ON/OFF button on the remote control unit is pushed.
In happens after a delay of 3 minutes when the compressor
is reoperated. The same phenomenon occurs when a power
is on.
As a phenomenon that the compressor is reoperated after a
delay of 3 minutes, the indoor fan is adjusted automatically
with reference to a temperature of the air blew.
The speed of the indoor fan is set to LL in DRY mode.
Fan speed is selected automatically in AUTO mode.
Compressor operation is controlled automatically in DRY
mode depending on the room temperature and humidity.
Timer is being activated and the unit is in ready mode.
The unit operates normally if the timer operation is cancelled.
The compressor stops intermittently or the fan speed of the
indoor unit decreases to prevent inside/outside air frozen
depending on the inside/outside air temperature.
When the unit is turned off while de-ice is activated,
the compressor continues operation for up to 9 minutes
(maximum) until the deice is completed.
The compressor and indoor fan stop intermittently if room
temperature exceeds a setting temperature in order to protect
the compressor from overheated air in a HEAT mode.
The compressor operates in a reverse cycle to remove
exterior ice in a HEAT mode, and indoor fan and outdoor fan
do not operate intermittently for within 20% of the total heater
operation
