16 FXMQ-M

2. BEFORE INSTALLATION

•

When moving the unit while removing it from the carton

box, be sure to lift it by holding on to the four lifting lugs

without exerting any pressure on other parts, espe-

cially, the refrigerant piping, drain piping, and other

resin parts

• Be sure to check the type of R410A refrigerant to be used

before installing the unit. (Using an incorrect refrigerant will

prevent normal operation of the unit.)

• The accessories needed for installation must be retained in

your custody until the installation work is completed. Do not

discard them!

• Decide upon a line of transport.

• Leave the unit inside its packaging while moving, until

reaching the installation site. Where unpacking is unavoid-

able, use a sling of soft material or protective plates

together with a rope when lifting, to avoid damage or

scratches to the unit.

• When moving the unit at or affter opening, hold the unit by

the hanger brackets (× 4). Do not apply force to the refrig-

erant piping, drain piping or plastic parts.

• For the installation of an outdoor unit, refer to the installa-

tion manual attached to the outdoor unit.

• Do not install or operate the unit in rooms mentioned below.

• Laden with mineral oil, or filled with oil vapor or

spray like in kitchens. (Plastic parts may deteriorate

which could eventually cause the unit to fall out of

place, or could lead to leaks.)

• Where corrosive gas like sulfurous gas exists. (Cop-

per tubing and brazed spots may corrode which

could eventually lead to refrigerant leaks.)

• Where exposed to combustible gases and where

volatile flammable gas like thinner or gasoline is

used. (Gas in the vicinity of the unit could ignite.)

• Where machines can generate electromagnetic

waves. (Control system may malfunction.)

• Where the air contains high levels of salt such as

that near the ocean and where voltage fluctuates

greatly such as that in factories.

Also in vehicles or vessels.

•

This unit, both indoor and outdoor, is suitable for installation in

a commercial and light industrial environment.

If installed as a household appliance it could cause electro-

magnetic interference.

2-1 PRECAUTIONS

• Be sure to read this manual before installing the indoor unit.

• Entrust installation to the place of purchase or a qualified

serviceman. Improper installation could lead to leaks and,

in worse cases, electric shock of fire.

• Use only parts provided with the unit or parts satisfying

required specifications. Unspecified parts could cause the

unit to fall out of place, or could lead to leaks and, in worse

cases, electric shock or fire.

• Be sure to mount an air filter (part to be procured in the

field) in the suction air passage in order to prevent water

leaking, etc.

2-2 ACCESSORIES

Check the following accessories are included with your

unit.

2-3 OPTIONAL ACCESSORIES

• A wired remote controller is necessary for this unit sepa-

rately.

• If you wish to use a remote controller that is different from

the above, select a suitable remote controller after consult-

ing catalogs and technical materials.
