Installation of Indoor, Outdoor Unit
1. Selection of the best location
1) Indoor unit 
Select location
Install the air conditioner in the location that satis-
fies the following conditions.
• The place shall easily bear a load exceeding four
times the indoor unit’s weight.
• The place shall be able to inspect the unit as the
figure.
• The place where the unit shall be leveled.
• The place shall allow easy water drainage.(Suit-
able dimension “H” is necessary to get a slope to
drain as figure.)
• The place shall easily connect with the outdoor
unit.
• The place where the unit is not affected by an
electrical noise.
• The place where air circulation in the room will be
good .
• There should not be any heat source or steam
near the unit.
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, fence or other obstacles.

• If 18K Model is installed at a distance of 15m, 
188g of refrigerant should be added (15-7.5) x 25g = 188g
• Capacity is based on standard length and maximun allowance length is on the basis of reliability.

• Drill the piping hole with 70mm dia, hole
core drill.
• Piping hole should be slightly slant to the
outdoor side.
INSULATION, OTHERS
Insulate the joint and tubes completely.
All thermal insulation must comply with local requirement.

1. Wrap the connecting portion of indoor unit with
the Insulation material and secure it with two
Plastic Bands. (for the right pipings)
• If you want to connect an additional drain hose,
the end of the drain-outlet should keep distance
from the ground. (Do not dip it into water, and fix
it on the wall to avoid swinging in the wind.) 
2. Tape the Pipings, drain hose and Connecting
Cable from bottom to top.
3. Form the pipings gathered by taping along the
exterior wall and fix it onto the wall by saddle
or equivalent.

1) PRECAUTIONS IN TEST RUN
• The initial power supply must provide at least 90% of the rated voltage.
Otherwise, the air conditioner should not be operated.
For test run, carry out the cooling operation firstly even during heating season. If heating operation
is carried out firstly, it leads to the trouble of compressor. Then attention must be paid.
Carry out the test run more than 5 minutes without fail.
(Test run will be cancelled 18 minutes later automatically)
• The test run is started by pressing the room temperature checking button and down timer button for 3 sec-
onds at the same time.
• To cancel the test run, press any button.
• After completing work, be sure to measure and record trial run properties, and store measured data, etc.
• Measuring items are room temperature, outside temperature, suction temperature, blow out temperature, wind
velocity, wind volume, voltage, current, presence of abnormal vibration and noise, operating pressure, piping
temperature, compressive pressure.
• As to the structure and appearance, check following items.
CHECK THE FOLLOWING ITEMS WHEN INSTALLATION IS COMPLETE
Caution
Is the circulation of air adequate?
Is the draining smooth?
Is the heat insulation complete
(refrigerant and drain piping)?
Is there any leakage of refrigerant?
Is the remote controller switch operated?
Is there any faulty wiring?
Are not terminal screws loosened?
