A high surge current from lightning or other sources may
cause damage to the air conditioner.
•
Do not touch the switch with wet fingers.
Touching a switch with wet fingers can cause electric shock.
•
Be sure to install an earth leakage breaker.
Failure to install an earth leakage breaker may result in elec-
tric shocks, or fire.
•
Do not install the air conditioner in the following locations:
(a) where a mineral oil mist or an oil spray or vapor is pro-
duced, for example in a kitchen
Plastic parts may deteriorate and fall off or result in water
leakage.
(b) where corrosive gas, such as sulfurous acid gas, is pro-
duced
Corroding copper pipes or soldered parts may result in
refrigerant leakage.
(c) near machinery emitting electromagnetic waves
Electromagnetic waves may disturb the operation of the
control system and result in a malfunction of the equipment.
•
Heat exchanger fins are sharp enough to cut.
To avoid injury wear gloves or cover the fins when working
around them.
•
Use of unspecified parts could lead to the unit falling,
leaks and, in worse cases, electric shock or fire.
•
Entrust installation to the place of purchase or a quali-
fied serviceman.
Improper installation could lead to leaks and, in worse cases,
electric shock or fire.
•
Refrigerant pipes may be very hot or very cold during or
immediately after operation.
Touching them could result in burns or frostbite. To avoid
injury give the pipes time to return to normal temperature or,
if you must touch them, be sure to wear proper gloves.
CAUTION
•
While following the instructions in this installation man-
ual, install drain piping in order to ensure proper drain-
age and insulate piping in order to prevent condensation.
Improper drain piping may result in water leakage and prop-
erty damage.
•
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.
•
Do not turn off the power immediately after stopping
operation.
Always wait at least five minutes before turning off the power.
Otherwise, water leakage and trouble may occur.
•
Make sure to provide for adequate measures in order to
prevent that the outdoor unit be used as a shelter by
small animals.
Small animals making contact with electrical parts can cause
malfunctions, smoke or fire. Please instruct the customer to
keep the area around the unit clean.
NOTE
•
Install the indoor and outdoor units, power supply wiring
and connecting wires at least 3.5ft. away from televisions
or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5ft. may not
be sufficient enough to eliminate the noise.)
•
Remote controller (wireless kit) transmitting distance
can result shorter than expected in rooms with elec-
tronic fluorescent lamps. (inverter or rapid start types)
Install the indoor unit as far away from fluorescent lamps as
possible.
•
Dismantling of the unit, treatment of the refrigerant, oil
and eventual other parts, should be done in accordance
with the relevant local and national regulations.

BEFORE INSTALLATION
WARNING
• 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.
• Use of unspecified parts could lead to the unit falling, leaks
and, in worse cases, electric shock or fire.
NOTE
• Be sure to read this manual before installing the indoor unit.
• 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.
The accessories needed for installation must be retained in
your custody until the installation work is completed. Do
not discard them!
1. Decide upon a line of transport.
2. 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.
When moving the unit while removing it from the packing
case, be sure to lift it by the four hanger brackets. Avoid
putting any pressure on other parts especially the refriger-
ant piping.
Be sure to check the type of R410A refrigerant to be used
before installing the unit.
(Using an incorrect refrigerant will prevent normal opera-
tion of the unit.)
For the installation of an outdoor unit, refer to the installation
manual attached to the outdoor unit.
2-1 PRECAUTIONS
• Be sure to instruct customers how to properly operate the
unit (operating different functions, and adjusting the temper-
ature ) by having them carry out operations themselves while
looking at the operation manual.
• Do not install in locations where the air contains high levels of
salt such as that near the ocean and where voltage fluctuates
greatly such as that in factories, or in vehicles or vessels.
