Safety Precautions
■ Read the following warnings and cautions carefully
before operating the system and use it correctly.
■ This manual classifies the precautions to the user
into two categories on the right. Be sure to follow
all as they are all important to ensure safety.
■ After reading this manual, keep it in a place easily
accessible to the user for future reference.
Failure to follow a warning is very likely
to result in such grave consequences
as death or serious injury.
WARNING
Failure to follow a caution may result in
serious injury or property damage, and
in certain conditions, may result in a
grave consequence.
CAUTION
Do not attempt to extend the
power cord by joining it to another
cord, or by using an extension
cord. Do not put any other loads
on the power supply socket.
Failure to follow this will cause electric
shocks, abnormal heating or fire.
Do not put a finger, a rod or other
objects into the air outlet or inlet.
As the fan is rotating at a high
speed, it will cause injury.
Do not attempt to repair, relocate,
modify or reinstall the air
conditioner by yourself.
Incorrect work will cause electric
shocks, fire etc. For repairs and
reinstallation, consult the shop
where you bought the air conditioner.
Do not damage or attempt to
modify the power cord. Do not use
the cord in a damaged state or
tied in a bundle.
Applying a heavy weight, heat or
tension on the power cord will damage
it, causing electric shocks or fire.
Do not expose your body to the
cool air for a long time; do not
cool the room too much.
It will affect your physical conditions
and cause health problems.
Do not use the air conditioner for
preservation purposes.
Do not use it for preserving precision
instruments, foods, plants, animals,
works of fine arts etc. Performance
or quality may deteriorate and
animal or plant life may be shorter.
Before cleaning, be sure to stop the
operation and turn the breaker OFF.
As a fan is rotating at a high speed,
cleaning during operation may cause
injury.
Do not place under the indoor or
outdoor unit anything which must
be kept away from moisture.
Indoor unit:
moisture in the air may
condense and drip in certain conditions.
Outdoor unit: during cooling opera-
tion, condensation may drip from the
piping connections.
Do not place a vessel containing
water on the unit.
Water may penetrate into the unit
and degrade electrical insulations,
resulting in an electric shock.
Do not operate the air conditioner
with a wet hand.
It may cause an electric shock.
After a long use, check the unit
stand and fittings for damage.
The unit may drop and cause injury
if damage is left unrepaired.
Do not wash the unit with water.
It may cause an electric shock.
Do not place a burning appliance
in places exposed to the air flow
from the unit or under the indoor
unit.
It may cause incomplete combustion
or deformation of the unit from heat.
Do not connect the air conditioner
to a power supply different from
the specification.
It may cause troublers or fire.
Ventilate the room from time to
time.
Be careful especially when using a
burning appliance in the same room.
Insufficient ventilation may cause
shortage of oxygen.
Do not stand or sit on the outdoor
unit. Do not place any object on
the unit.
The object or the person may fall
down or drop, causing injury.
Do not expose plants or animals
directly to the air flow.
It may cause adverse effects on the
plant or the animal.
Do not allow children to mount on
the outdoor unit or avoid placing
any object on it.
Falling or tumbling may result in injury.
Do not block air inlets nor outlets.
Impaired air flow may result in
insufficient performance or troubles.
WARNING
CAUTION
If anything abnormal
such as a burning smell
occurs, stop the opera-
tion immediately and
turn the breaker OFF.
Continued abnormal op-
eration will cause
troubles, electric shocks,
fire etc. If anything is
abnormal, consult the
shop where you bought
the air conditioner.
If the air conditioner is not cooling or heating
properly, the refrigerant may be leaking, so
see the dealer where the unit was purchased.
Check with a qualified repairman before
attempting any repairs, which might accom-
pany addition of refrigerant.
The refrigerant used in the air conditioner is safe.
Although leaks should not occur, if for some reason
any refrigerant happens to leak into the room, make
sure it does not come in contact with any flame, such
as fan heaters, kerosene heaters, or gas ranges, as
this may result noxious substances being generated.

Installation
Do not attempt to install the air conditioner by yourself.
Consult the service shop or a qualified technician.
Incorrect work will result in water leakage, electric shocks or fire. For installation, consult the service
shop where you bought the unit or a qualified technician.
WARNING
The air conditioner must be earthed.
Incomplete earthing may result in electric
shocks.
Do not connect the earth line to a gas pipe,
water pipe, lightening rod, or a telephone
earth line.
Do not install the air conditioner in places
where flammable gas may leak.
If leaked gas should accumulate near the unit,
fire may occur.
Depending on the environment, an earth
leakage breaker must be installed.
Lack of an earth leakage breaker may result in
electric shocks.
Arrange the drain hose to ensure smooth
drainage.
Incomplete drainage may cause wetting of the
building, furniture etc.
CAUTION
Installation site
■ To install the air conditioner in the following types of
environments, consult the shop.
Places with an oily ambient or where steam or soot occurs.
Salty environment such as coastal areas.
Places where sulfide gas occurs such as hot springs.
Places where snow may block the outdoor unit.
The drain from the outdoor unit must be discharged to a place
of good drainage.
Consider nuisance to your neighbours from noises.
■ For installation, choose a place as described below.
A place solid enough to bear the weight of the unit which does not amplify the operation noise or vibration.
A place from where the air discharged from the outdoor unit or the operation noise will not annoy your neighbours.
Electrical work
For power supply, be sure to use a separate power circuit dedicated to the air conditioner.
System relocation
Relocating the air conditioner requires specialized knowledge and skills. Please consult the shop where you bought the air
conditioner if relocation is necessary for moving or remodeling.
