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.
WARNING
● 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 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 dealer
where you bought the air conditioner.
WARNING
Failure to follow a warning is very likely
to result in such grave consequences as
death or serious injury.
CAUTION
Failure to follow a caution may result in
serious injury or property damage, and
in certain conditions, may result in a
grave consequence.
If anything abnormal such as a burning smell occurs, stop the operation immediately and turn the breaker OFF.
●
Continued abnormal operation will cause troubles, electric shocks, fire etc. If anything is
abnormal, consult the dealer 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 accompany 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.
CAUTION
● 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.
● Do not operate the air conditioner with a wet hand.
It may cause an electric shock.
● 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.
● 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.
● 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 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 pull at the conduit or hang anything on it.
Otherwise it will cause fire or electric shock.

● 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 : during cooling operation, condensation may drip from the piping connections.
● 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 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 expose plants or animals directly to the air flow.
It may cause adverse effects on the plant or the animal.
● Do not block air inlets nor outlets.
Impaired air flow may result in insufficient performance or troubles.
● Do not allow children to mount on the outdoor unit or avoid placing any object on it.
Falling or tumbling may result in injury.
● Depending on the usage environment, water may leak from the air conditioner.
If this happens, contact your Trane Dealer.
Installation
WARNING
● Do not attempt to install the air conditioner by yourself.
Consult the dealer or a qualified technician.
Incorrect work will result in water leakage, electric shocks or fire. For installation, consult the
dealer where you bought the unit or a qualified technician.
● The air conditioner must be grounded.
Incomplete grounding may result in electric shocks. Do not connect the ground line to a gas pipe,
water pipe, lightning rod, or a telephone ground line.
CAUTION
● Depending on the environment, a ground fault interrupter might be installed.
Lack of a ground fault interrupter might result in electric shocks.
● Do not install the air conditioner in places where flammable gas may leak.
If leaked gas should accumulate near the unit, fire may occur.
● Arrange the drain hose to ensure smooth drainage.
Incomplete drainage may cause wetting of the building, furniture etc.
● Do not connect the air conditioner to a power supply different from the specification.
It may cause trouble or fire.

Installation site
■ To install the air conditioner in the following types of environments, consult the dealer.
● 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 dealer
where you bought the air conditioner if relocation is necessary for moving or remodeling.
