lamps (inverter or rapid start types).
Install the indoor unit as far away from fluorescent lamps as
possible.
• Do not install the air conditioner in the following locations:
1. Where there is a high concentration of mineral oil spray or
vapour (e.g. a kitchen).
Plastic parts will deteriorate, parts may fall off and water
leakage could result.
2. Where corrosive gas, such as sulphurous acid gas, is pro-
duced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3. Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
4. Where flammable gas may leak, where there is carbon
fibre or ignitable dust suspensions in the air, or where vol-
atile flammables such as paint thinner or gasoline are
handled.
Operating the unit in such conditions may result in fire.
• The air conditioner is not intended for use in a potentially
explosive atmosphere.
2. BEFORE INSTALLATION
•
When moving the unit while removing it from the packing
case, be sure to lift it by holding on to the four lifting lugs
without exerting any pressure on other parts, especially,
the refrigerant pipe and drain socket
.
• 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 packing case 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 scratch to the
unit.
• For the installation of an outdoor unit, refer to the installation
manual attached to the outdoor unit.
• Do not install or operate the unit in the place 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 gas and where volatile
liquid 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 install as a household appliance it may cause electromag-
netic interference.
2-1 PRECAUTIONS
• Be sure to read this manual before installing the unit.
• Entrust installation to the place of purchase or a qualified ser-
viceman. 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. (Accessories are placed in the air outlet of unit.)
2-3 OPTIONAL ACCESSORIES
• A wired remote controller is necessary for this unit sepa-
rately.
NOTE
• If you wish to use a remote controller that is different from the
above, select a suitable remote controller after consulting
catalogs and technical materials.
