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 specied

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.

Floor Ceiling Air-Conditioning 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 airow can reach

every corner of the room.

(3) Leave service space around the unit as required in Fig.2.

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 specications 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 specications 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 modied 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 modied
