1. Precautions
11) Cut off the power.
● Make sure to cut off the power before repair. If not, you may
be damaged by an electric shock.
12) Do not install an outdoor unit on the apartment outside
wall(or equivalent) for safety.
● Installing an outdoor unit on the apartment outside wall(or
equivalent) is prohibited for the safety purpose. Service will
not be available for the outdoor unit where our servicemen
can not access and the cost of moving the outdoor unit to
the service area will be borne by the customer.
● If requested by the customer, you shall discourage him to
install an outdoor unit on the apartment outside wall(or
equivalent).
13) The air conditioner outdoor unit shall be installed 2m
above ground and kept away from pedestrians to prevent
direct exposure to hot wind. (according to the Building
Facility Standard Regulations)
14) Keep the drain hose outlet free.
● Otherwise, air flow will get slow, which may hinder cooling
capacity.
● Also, dew may be laden on the service valve.
15) Use of Certified Parts
● Use certified parts only. (An electric contact part, if broken
down, shall not be repaired but replaced with a new one.
Remodeling shall be prohibited. In no case, the customer
shall repair the product on his own because this is dangerous enough to bring about breakdown or fire.)
16) Ban on Middle Connection of Power Cord
● Do not cut the power cord in the middle to be connected to
other power cord nor use a middle socket between two
power cords. This is dangerous enough to bring about
breakdown or fire.
17) Check Insulation
● After assembly, be sure to check insulation resistance.
(Use an insulation ohmmeter to measure the insulation
resistance between the power cord and the earthing wire.
Do not supply power until it reads 30MΩ.)
18) Be sure to keep the symmetry of the product.
● Otherwise, you may hear vibration noise.
19) Caution for Children
● Do not keep children off the product while it is in repair.
Otherwise, they might be endangered.
10) Be sure to put the indoor or outdoor unit free of corrosive
gases such as sulfuric water, ammonium, and sulfuric
gas.
● Otherwise, copper tubes or soldered parts could be
corroded causing refrigerant leak.
11) Arrangement of surroundings
● After repair finishes, clean the air conditioner and its
surroundings and inform the customer of what it is like.

3-3-1 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.
3-3-2 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.

3-4-1 Air-Purge Procedure
1) Connect each assembly pipe to the appropriate
valve on the outdoor unit and tighten the flare nut.
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.
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.

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.
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.

Operating Instructions & Installation
3-4-2 Refrigerant Refill(R410A)
Refill an air conditioner with refrigerant when refrigerant has been leaked at installing or using.
1) Purge air(for new installation only).
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.
3) Connect the tank to refill with refrigerant.
4) Set the unit to cool operation mode.
5) Check the pressure indicated by the pressure
gauge(low pressure side).
* Standard pressure is should be 9.0~10.0kg/cm
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.

Operating Instructions & Installation
3-4-3 "Pump down" Procedure
Pump down will be carried out when an evaporator is replaced or when the unit is relocated in another area.
1) Remove the caps from the 3-Way valve and the
3-Way 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.
3) Set the unit to cool operation mode.
(Check if the compressor is operating.)

4) Turn the 3-Way valve clockwise to close.
5) When the pressure gauge indicates "0" turn the
3-Way valve clockwise to close.
6) Stop operation of the air conditioner.
7) Close the cap of each valve.
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.
