CAUTION

™It is important that the following safety precautions be followed during installation of the air-conditioning equipment:

¡Do not place the air conditioner’s remote control unit in any location where it will be exposed to direct sunlight as this can cause the remote

control unit to be damaged or warped.

¡The equipment must be grounded; the ground wire should not be connected to either gas pipe, water pipe, lightning rod, or telephone ground

wires. Incorrect operation of the air conditioner or electric shocks can result if the grounding is not performed correctly.

¡An earth leakage breaker is required to be fitted in order to provide protection against the possibility of electric shocks, fires, and other similar

accidents.

¡Ensure that the air conditioner is securely installed in a location which is fully capable of supporting its weight. Failure to do so could result in a

number of different problems such as the unit toppling over and causing injury or generating increased operation noise due to vibration.

¡If there is a possibility that the in-door unit’s refrigerant concentration could exceed the threshold concentration (0.3 kg/m

) and result in

suffocation should a leakage of this gas occur, it will be necessary to provide an opening between the room containing the indoor unit and

neighboring rooms or to provide mechanical ventilating equipment which operates in response to gas leak warnings. Consult with staff at your

local sales outlet when purchasing such products.

Request

™Please do not install and use the air-conditioning equipment in locations such as the following:

(1) In the vicinity of equipment which generates electromagnetic waves, such as that often found in hospitals, or in the vicinity of equipment

which generates high frequency waves: Installation in such locations is to be avoided as the generation of electromagnetic noise can cause

the controller to operate incorrectly.

(2) Areas which are exposed to salt air wind, such as coastal regions: Salt air can accelerate the corrosion of outer plating and the heat exchanger.

(3) Kitchens, machinery plants, and other similar locations where splashing and/or spraying of oil and grease occurs frequently or where a large

amount of heated air is present: Grease and hot air can easily enter and disrupt the operation of the indoor unit, and thus, the unit should not

be installed in such locations. In addition, these factors can also lead to reduced performance and/or corrosion of the heat exchanger as well

as resulting in damage to plastic parts.

(4) Any location where there is a possibility that corrosive gasses (sulfurous acid, etc.) or inflammable gasses (paint thinner vapor or gasoline

vapor, etc.) could be produced or could accumulate; also, installation and use of this air conditioner equipment in locations where volatile

inflammable substances are handled is to be avoided: These factors can lead to corrosion of the heat exchanger and to damage to plastic parts.

In addition, there is also a possibility that inflammable gasses could be ignited in the presence of the air-conditioner.

™If spatter generated during welding and other similar operations comes into contact with the indoor unit, it may result in the unit being damaged.

Therefore, in addition to requesting that the utmost care be taken when performing this type of work in the vicinity of the air-conditioner

equipment, it is also requested that the unit be covered to prevent spatter from passing to its interior.

¡ Install the indoor securely in a location

which is fully capable of supporting its

weight. Installing in a location which is

not sufficiently reinforced or supported

may result in the indoor unit toppling and

falling, resulting in damage or injury.

Request

¡ It is important that enough space is

provided for performing maintenance

operations.

Request

Obtain the consent of the customer to

install the indoor unit in a location

which satisfies the following condi-

tions:

¡ Warm and cold air must be able to

dissipate freely.

¡ It must be possible to easily

connect wiring and piping to the

outdoor.

¡ The installation of a drain must be

possible.

¡ The section of floor for installation

must be sufficiently reinforced.

¡ Direct sunlight must not fall on the

in-door unit.

¡ There must be no obstacles or

blockages in the vicinity of the

suction air and discharge air

openings.

¡ There must be no possibility of

faulty operation of a fire alarm, as

must there be no possibility of short

circuits.
