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 firmly 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 specified

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.

(9). This appliance is not intended for use by persons (including children) with reduced physical,

sensory or mental capabilities, or lack of experience and knowledge, unless they have been

given supervision or instruction concerning use of the appliance by a person responsible for their

safety.

(10). Children should be supervised to ensure that they do not play with the appliance.

(11). If the supply cord is damaged, it must be replaced by the manufacturer, its service agent or

similarly qualied persons in order to avoid a hazard.

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 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.

DC Inverter U-match Series Duct Type Unit

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 fixed

securely.

(1). If possible, do not install the unit where it will be exposed to direct sunlight. (If necessary,

install a blind that does not interfere with the air ow.)

(2). Install the outdoor unit in a place where it will be free from getting dirty or getting wet by

rain as much as possible.

(3). Install the outdoor unit where it is convenient to connect the indoor unit.

(4). Install the outdoor unit where the condensate water can be drained out freely during

heating operation. Do not place animals and plants in the path of the warm air.

(5). Take the air conditioner weight into account and select a place where noise and vibration

are small.

(6). Install the outdoor unit where is capable of withstanding the weight of the unit and

generates as less noise and vibration as possible.

(7). Provide the space shown in Fig.3, so that the air flow is not blocked. Also for efficient

operation, leave three of four directions of peripheral constructions open.
