1 Safety Precautions
WARNING! This mark indicates procedures which, if improperly performed, might lead to
the death or serious injury of the user.
CAUTION! This mark indicates procedures which, if improperly performed, might possibly
result in personal harm to the user, or damage to property.
WARNING!
① .
For operating the air conditioner pleasantly, install it as outlined in this installation manual.
② .
Connect the indoor unit and outdoor unit with the room air conditioner piping and
cord available from our standard parts. This installation manual describes the correct
connections using the installation set available from our standard parts.
③ .
Installation work must be performed in accordance with national wiring standards by
authorized personnel only.
④ .
If refrigerant leaks while work is being carried out, ventilate the area. If the refrigerant
comes in contact with a ame, it produces toxic gas.
⑤ .
Do not power on until all installation work is complete.
⑥ .
During installation, make sure that the refrigerant pipe is attached rmly before you run the
compressor.
Do not operate the compressor under the condition of refrigerant piping not attached properly with
2-way or 3-way valve open.
This may cause abnormal pressure in the refrigeration cycle that leads to breakage and even
injury.
⑦ .
During the pump-down operation, make sure that the compressor is turned off before you
remove the refrigerant piping.
Do not remove the connection pipe while the compressor is in operation with 2-way or 3-way
valve open.
This may cause abnormal pressure in the refrigerant cycle that leads to breakage and even injury.
⑧ .
When installing and relocating the air conditioner, do not mix gases other than the specied
refrigerant (R410A) to enter the refrigerant cycle.
If air or other gas enters the refrigerant cycle, the pressure inside the cycle will rise to an
abnormally high value and cause breakage, injury, etc.

3.2 Selection of the Installation Location
WARNING!
The unit must be installed where strong enough to withstand the weight of the unit and xed securely,
otherwise the unit would topple or fall off.
CAUTION!
① .
Do not install where there is a danger of combustible gas leakage.
② .
Do not install the unit near heat source, steam, or ammable gas.
③ .
Children under 10 years old must be supervised not to operate the unit.

Decide the installation location with the customer as follows:
3.2.1 Indoor Unit
(1) Install the unit at a place where is strong enough to withstand the weight of the unit.
(2) The air inlet and outlet of the unit should never be clogged so that the airow can reach
every corner of the room.
(3) Leave service space around the unit as required in Fig.2.

(4) Install the unit where the drain pipe can be easily installed.
(5) The space from the unit to the ceiling should be kept as much as possible so as for more
convenient service.
3.2.2 Outdoor Unit
WARNING!
① .
Install the unit where it will not be tilted by more than 5°.
② .
During installation, if the outdoor unit has to be exposed to strong wind, it must be xed
securely.
(1) Outdoor Unit must be xed on stable and solid surface of oor.
(2) Don’t install Outdoor Unit under window or between buildings, and prevent the operation
noise from room.
(3) There should be no obstructions at both air inlet and outlet of indoor and outdoor units for
maintaining well air ventilation.

3.3 Connection Pipe Requirement
CAUTION!
The maximum length of the connection pipe is listed in the table below. Do not place the units between
which the distance exceeds the maximum length of the connection pipe.

◆The connecting pipe should be thermally insulated properly.
◆The pipe wall thickness shall be 0.5-1.0 mm and the pipe wall shall be able to withstand
the pressure of 6.0 MPa. The longer the connecting pipe, the lower the cooling and heating
effect performs.

Notes:
① .
Install the disconnect device with a contact gap of at least 3 mm in all poles nearby the units
(Both indoor unit and outdoor unit).The appliance must be positioned so that the plug is
accessible.
② .
The specications of the breaker and power cable listed in the table above are determined
based on the maximum power (maximum amps) of the unit.
③ .
The specications of the power cable listed in the table above are applied to the conduit-
guarded multi-wire copper cable (like, YJV copper cable, consisting of PE insulated wires and
a PVC cable jacket) used at 40°С and resistible to 90°С(see IEC 60364-5-52). If the working
condition changes, they should be modied according to the related national standard.
④ .
The specifications of the breaker listed in the table above are applied to the breaker with
the working temperature at 40°С. If the working condition changes, they should be modied
