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.

(1)  Install the DX-kit on a place having a suf

fi

 cient strength so that it withstands against 

the weight of the DX-kit.

(2)  Leave the space required to service the DX-kit.
(3)  Install the unit where connection to the outdoor unit (or RB unit) is easy. 
(4)  Install the unit where the connection pipe can be easily installed. 
(5)  Install the unit where noise and vibrations are not ampli

fi

 ed. 

(6)  Take servicing, etc., into consideration and leave the spaces.
(7)  Do not install the unit where it will be exposed to direct sunlight.

4.3. Installing the unit

 

WARNING

Install the DX-kit in a location which can withstand a load of at least 5 times the weight 
of the main unit and which will not amplify sound or vibration. If the installation location 
is not strong enough, the DX-kit may fall and cause injuries.

If the job is done with the panel frame only, there is a risk that the unit will come loose. 
Please take care.

Carrying in and installation of the unit should be performed by a suf

fi

 cient  number 

of people and with suf

fi

 cient equipment that is adequate for the weight of the unit. 

Performing such work by an insufficient number of people or with inadequate 
equipment could result in dropping of the unit or personal injury.

4. INSTALLATION WORK

Correct initial installation location is important because it is dif

fi

 cult to move unit after it is 

installed.

4.1. 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 DX-kit. Install 
the units securely so that they do not topple or fall.

 

CAUTION

Do not install the DX-kit in the following areas:
•  Area with high salt content, such as at the seaside. It will deteriorate metal parts, 

causing the parts to fail 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 fail or the unit 
to leak water. 

•  Area that generates substances that adversely affect the equipment, such as sulfuric 

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 use the unit for special purposes, such as storing food, raising animals, 
growing plants, or preserving precision devices or art objects.
It can degrade the quality of the preserved or stored objects.

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 DX-kit, 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 conditions.)
