•
While following the instructions in this installation manual,
install drain piping to ensure proper drainage and insulate
piping to prevent condensation.
Improper drain piping may result in indoor water leakage and
property damage.
•
Install the indoor and outdoor units, power cord and connect-
ing wires at least 1 meter away from televisions or radios to
prevent picture interference and noise.
(Depending on the incoming signal strength, a distance of 1
meter may not be sufficient to eliminate noise.)
•
Remote controller (wireless kit) transmitting distance can be
shorter than expected in rooms with electronic fluorescent
lamps (inverter or rapid start types).
Install the indoor unit as far as possible from fluorescent
lamps.
!
CAUTION
•
Do not install the air conditioner in the following locations:
1.
2.
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.
Where corrosive gas, such as sulphurous acid gas, is pro-
duced.
Corroding of copper pipes or soldered parts may result in
refrigerant leakage.
3.
4.
Near machinery emitting electromagnetic radiation.
Electromagnetic radiation may disturb the operation of the
control system and result in a malfunction of the unit.
Where flammable gas may leak, where there is carbon
fibre or ignitable dust suspensions in the air, or where
volatile 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.
Do not touch the heat exchanger fins.
Improper handling may result in injury.
Be very careful about product transportation.
Some products use PP bands for packaging. Do not use any
PP bands for a means of transportation. It is dangerous.
•
Safely dispose of the packing materials.
Packing materials, such as nails and other metal or wooden
parts, may cause stabs or other injuries.
Tear apart and throw away plastic packaging bags so that
children will not play with them. If children play with a plastic
bag which was not torn apart, they face the risk of suffocation.
•
Do not turn off the power immediately after stopping operation.
Always wait at least 5 minutes before turning off the power.
Otherwise, water leakage and trouble may occur.
•
In a domestic environment this product may cause radio
interference in which case the user may be required to take
adequate measures.
•
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, especially,
the refrigerant piping, drain piping, flanges 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. Decide transportation medium.
•
Leave the unit inside its packaging while moving, until reach-
ing the installation site. Where unpacking is unavoidable, use
a sling of soft material or protective plates together with a
rope when lifting, to avoid damage or scratches to the unit.
•
For the installation of outdoor unit, refer to the installation
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.)
Follow national standards for installation work.
2. BEFORE INSTALLATION
•
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
vol-atile 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.
•
•
Be sure to read this manual before installing the indoor 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 or fire.
•
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.

PRECAUTIONS
Check that the following accessories are provided and that each
accessory is correct in amount.
Refer to the Fig. 1 of this sheet.
[PRECAUTION]
The accessories are required for the installation of the air con-
ditioner. Be sure to keep them until the installation work is
completed
•
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.
