Safety Precautions
Below are listed four kinds of Safety Cautions and Suggestions:
Be sure to conform with the following important Safety Cautions.
The Safety Cautions should be at hand so that they can be checked at any time when needed.
If the air conditoner is transferred to the new user, this manual should be as well transferred to
the new user.
Incorrect operations may result in severe consequences of death or serious injures.
WARNING:
Incorrect operations may result in injures or machine damages; in some cases may
cause serious consequences.
CAUTION :
: It must be strictly prohibited where marked with ì Prohibited î, otherwise may result in
machine damages or endanger the userípersonal safety.
This information can ensure the correct operation of the machine.
INSTRUCTION:
Carefully read the following information in order to operate the air conditioner correctly.
WARNING
If any abnormal phenomena are found (e.g.
smell of firing),please cut off the power supply
immediately, and contact the dealer to find outí
the handling method.
When need maintenance and
repair,call dealer to handle it.
Donít put figures or any other
things into the inlet/outlet and
swing louver while the conditi-
oner is in operation
Call the dealer to take measures to prevent the
refrigerant from leaking.
Switch
off
In such case,to continue using
the air conditioner will damage
the conditioner,and may cause
electrical shock or fire hazard.
Incorrect maintenance and
repair may cause water leak,
electrical shock and fire hazard.
Because the high-speed fan
is very dangerous and may
cause injures.
The leaked refrigerant over certain density may
cause oxygen deficient.If the air conditioner is
installed in a small room be sure to take measure
in order to prevent suffocation accident even in
case of refrigerant leakage
When air conditioner is removed and reinstalled
dealer should be responsible for them.
Incorrect installation may cause water leaking,
electrical shock and fire hazard.
Donít dismantle the outlet of the outdoor unit.
The exposure of fan is very
dangerous witch may harm
human beings.
After a long time use of air conditioner the base
should be checked for any damages.
If the damaged base is not
repaired, the unit may fall
down and cause accidents.
15

Earthing wire should not be
connected to the gas pipe,
water pipe,lightning rod or
phone line,incorrect earthing
may cause shock.
Use discharge pipe correctly to
ensure efficient discharge.
In correct pipe usage may cause water
leaking.
Air conditioner canít be be installed in
the environment with inflammable gases.
The inflammable gases near to air conditioner
may cause fire hazard.
Installed electrical-leaking circuit breaker.
When use the fumigating insecticide
donít operate air conditioner.
Otherwise the poisonous chemicals
may settle in air conditioner,
which harm the health of
chemical-allergic people.

Water flowing sound is heard
When the air conditoner is started, when the
compressor starts or stops during operation
or when the air conditioner is stopped,it som-
etimes sounds ì Bi- Bi-î or ìGodo-Godoî. It is
the flowing sound of the refrigerant , not a
malfunction.
Cracking sound is heard
It smells.
This is caused by heat expansion or contra-
ction of plastics
Air blown out from the indoor unit sometimes
smells. The smell results from smells of
furniture, paint , tobacco absorbed by indoor
unit.
During operation, white fog comes out of
indoor unit.
When in COOL or DRY mode, a thin water
fog can be seen blown out of unit ,this is the
condensed fog because the suddenly cooled
indoor air is blown out.

indoor unit heat exchanger, it sometimes auto-
matically switched into the FAN mode,but it will
soon back to the cooling mode.

after it stops.
Air conditioner does not start?
