General Precautions and Warnings
WARNING
To avoid risk of personal injury or death due to electrical shock,disconnect electrical power to unit
before attempting to service the unit.
WARNING
To avoid risk of personal injury or death due to electrical shock,DO NOT,under any circumstances,alter
the grounding plug .Air conditioner must be grounded at all times.Do not remove warning tag from power
cord.If a two-prong (non-grounding) wall receptacle is encountered,contact a qualified electrician and
have the receptacle replaced with a properly grounder wall receptacle in accordance with the National
Electrical Code.
WARNING
To avoid risk of personal injury or death due to electrical shock,grounding wires and wires colored like
grounding wires are NOT to be used as current carrying conductors.The standard accepted color coding
for ground wires is green or green with a yellow stripe.Electrical components such as the compressor
and fan motor are grounded through an individual wire attached to the electrical component and to
another part of the air conditioner.Grounding wires should not to be removed from individual components
while servicing,unless the component is to be removed and replaced.It is extremely important to replace
all removed grounding wires before completing service.
WARNING
To avoid risk of heat exposure,which may cause death or severe illness,air conditioner must be
monitored when malfunctions or shuts down.

Is the air filter dirty? Normally it should be
cleaned every 15 days.
Are there any obstacles before inlet and outlet?
Is temperature set correctly?
Are there some doors or windows left open?
Is there any direct sunlight through the
window during the cooling operation?(Use
curtain)
Are there too much heat sources or too many
people in the room during cooling operation?
Cause or check points
Phenomenon
The system does not restart
immediately.
Noise is heard:
Smells are generated.
Mist or steam are blown out.
Does not work at all.
Multiple
check
Normal
Performance
inspection
Poor cooling
Before asking for service, check the following first.
When unit is stopped, it won't restart
immediately until 3 minutes have elapsed
to protect the system.
When the electric plug is pulled out and
reinserted, the protection circuit will work
for 3 minutes to protect the air conditioner.
During unit operation or at stop, a swishing
or gurgling noise may be heard. At first 2-3
minutes after unit start, this noise is more
noticeable. (This noise is generated by
refrigerant flowing in the system.)
During unit operation, a cracking noise may
be heard. This noise is generated by the
casing expanding or shrinking because of
temperature changes.
Should there be a big noise from air flow in
unit operation, air filter may be too dirty.
This is because the system circulates smells
from the interior air such as the smell of
furniture, cigarettes.
During COOL or DRY operation, indoor unit
may blow out mist. This is due to the sudden
cooling of indoor air.
Is power plug inserted?
Is there a power failure?
Is fuse blown out?
