• Before touching electrical parts, turn off the unit.
• 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 equip-
ment.
• 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
• Install drain pipe in order to ensure proper drainage and
do the thermal insulation of the pipe in order to prevent
condensate.
Improper drain pipe may result in water leakage and property
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.
• 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.
• 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 wire
and transmission wire at least 3.5 ft. away from televisions
or radios in order to prevent image interference or noise.
(Depending on the radio waves, a distance of 3.5 ft. 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.
• In a domestic environment this product may cause radio
interference in which case the user may be required to
take adequate measures.
• 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.
2. BEFORE INSTALLATION
• When moving the unit while removing it from the pack-
ing case, be sure to lift it by the four hanger brackets.
Avoid putting any pressure on other parts especially the
refrigerant piping.
• Be sure to check the type of 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 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 selecting installation site, refer to the paper pattern.
• 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 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.
(Copper tubing and brazed spots may corrode which
could eventually lead to refrigerant leaks.)
• 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.
WARNING
• Entrust installation to the place of purchase or a qualified
person. Improper installation could lead to leak and, in worse
cases, electric shock of 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.
