3. INSTALLATION WORK

Especially, the installation place is very important for the split type air conditioner because 
it is very dif

fi

 cult to move from place to place after the 

fi

 rst installation.

3.1. Selecting an installation location

Decide the mounting position together with the customer as follows.

 WARNING

Select installation locations that can properly support the weight of the indoor unit. 
Install the units securely so that they do not topple or fall.

 CAUTION

Do not install the indoor unit in the following areas:

Area with high salt content, such as at the seaside. It will deteriorate metal parts, 

• 

causing the parts to fall or the unit to leak water.
Area 

fi

 lled with mineral oil or containing a large amount of splashed oil or steam, 

• 

such as a kitchen. It will deteriorate plastic parts, causing the parts to fall or the unit 
to leak water. 
Area that generates substances that adversely affect the equipment, such as sulfu-

• 

ric gas, chlorine gas, acid, or alkali. It will cause the copper pipes and brazed joints 
to corrode, which can cause refrigerant leakage. 
Area that can cause combustible gas to leak, contains suspended carbon 

fi

 bers or 

• 

fl

 ammable dust, or volatile in

fl

 ammables such as paint thinner or gasoline. If gas 

leaks and settles around the unit, it can cause a 

fi

 re.

Area where animals may urinate on the unit or ammonia may be generated.

• 

Do not install where there is the danger of combustible gas leakage.

Do not install the unit near a source of heat, steam, or 

fl

 ammable gas.

Install the indoor unit, outdoor unit, power supply cable, transmission cable, and 
remote controller cable at least 1 m away from a television or radio receivers. The 
purpose of this is to prevent TV reception interference or radio noise. (Even if they are 
installed more than 1 m apart, you could still receive noise under some signal condi-
tions.)

If children under 10 years old may approach the unit, take preventive measures so that 
they cannot reach the unit.

Take precautions to prevent the unit from falling.

 Install the indoor unit on a place having a suf

fi

 cient strength so that it withstands 

(1) 

against the weight of the indoor unit.
 The inlet and outlet ports should not be obstructed; the air should be able to blow all 

(2) 

over the room.
Leave the space required to service the air conditioner.

(3) 

Install the unit where connection to the outdoor unit is easy. 

(4) 

Install the unit where the connection pipe can be easily installed. 

(5) 

Install the unit where the drain pipe can be easily installed.

(6) 

Install the unit where noise and vibrations are not ampli

fi

 ed.

(7) 

 Take servicing, etc., into consideration and leave the spaces. Also install the unit 

(8) 

where the 

fi

 lter can be removed.

Do not install the unit where it will be exposed to direct sunlight.
