Troubleshooting
Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue Possible Causes
Unit does not turn
on when pressing
ON/OFF button
The Unit has a 3-minute protection feature that prevents the unit from overloading.
The unit cannot be restarted within three minutes of being turned o.
The unit may change its setting to prevent frost from forming on the unit.
Once the temperature increases, the unit will start operating in the
previously selected mode again.
The set temperature has been reached, at which point the unit turns o the
compressor. The unit will continue operating when the temperature
fluctuates again.
The indoor unit
emits white mist
In humid regions, a large temperature dierence between the room’s air
and the conditioned air can cause white mist.
Both the indoor and
outdoor units emit
white mist
When the unit restarts in HEAT mode after defrosting, white mist may be
emitted due to moisture generated from the defrosting process.
Troubleshooting
The unit changes from
COOL/HEAT mode to
FAN mode
The indoor unit makes
noises
A rushing air sound may occur when the louver resets its position.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
Both the indoor unit
and outdoor unit make
noises
Low hissing sound during operation: This is normal and is caused by refrigerant
gas flowing through both indoor and outdoor units.
Low hissing sound when the system starts, has just stopped running, or is
defrosting: This noise is normal and is caused by the refrigerant gas stopping or
changing direction.
Squeaking sound: Normal expansion and contraction of plastic and metal parts
caused by temperature changes during operation can cause squeaking noises.
SAFETY PRECAUTIONS
If any of the following conditions occurs, turn o your unit immediately!
• The power cord is damaged or abnormally warm
• You smell a burning odor
• The unit emits loud or abnormal sounds
• A power fuse blows or the circuit breaker frequently trips
• Water or other objects fall into or out of the unit
DO NOT ATTEMPT TO FIX THESE YOURSELF! CONTACT AN AUTHORIZED
SERVICE PROVIDER IMMEDIATELY!
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, the outdoor temperature is too cold and the unit’s
anti-cold wind is activated in order to defrost the unit.
In Cooling-only Models: If the “Fan Only” indicator is lit up, the outdoor
temperature is too cold and the unit’s anti-freeze protection is activated in
order to defrost the unit.
A squeaking sound is heard when the system is OFF or in COOL mode. The
noise is also heard when the drain pump (optional) is in operation.
Page 13
Troubleshooting
Issue Possible Causes
The outdoor unit
makes noises
The unit will make dierent sounds based on its current operating mode.
Dust is emitted from
either the indoor or
outdoor unit
The unit may accumulate dust during extended periods of non-use, which will be
emitted when the unit is turned on. This can be mitigated by covering the unit during
long periods of inactivity.
The unit emits a
bad odor
The unit may absorb odors from the environment (such as furniture, cooking,
cigarettes, etc.) which will be emitted during operations.
The unit’s filters have become moldy and should be cleaned.
The fan of the outdoor
unit does not operate
During operation, the fan speed is controlled to optimize product operation.

Step 8: Connect drain hose
The drainpipe is used to drain water away from
the unit. Improper installation may cause unit
and property damage.
CAUTION
• Insulate all piping to prevent condensation,
which could lead to water damage.
• If the drainpipe is bent or installed
incorrectly, water may leak and cause a
water-level switch malfunction.
• In HEAT mode, the outdoor unit will
discharge water. Ensure that the drain hose
is placed in an appropriate area to avoid
water damage and slippage.
• DO NOT pull the drainpipe forcefully. This
could disconnect it.

NOTE ON DRAINPIPE INSTALLATION
• When using an extended drainpipe,
tightenthe indoor connection with an
additionalprotection tube. This prevents
it from pulling loose.
• The drainpipe should slope downward at a
gradient of at least 1/100 to prevent water
from flowing back into the air conditioner.
• To prevent the pipe from sagging, space
hanging wires every 1-1.5m (39-59”).
• If the outlet of the drainpipe is higher than
the body’s pump joint, use a lift pipe for
the indoor unit’s exhaust outlet. The lift
pipe must be installed no higher than
55cm (21.7”) from the ceiling board. The
distance between the unit and the lift pipe
must be less than 20cm (7.9”). Incorrect
installation could cause water to ow back
into the unit and ood.
NOTE: When connecting multiple drainpipes,
install the pipes as illustrated.
•
To prevent air bubbles, keep the drain
hose level or slightly tiled up (<75mm / 3”).

Preparations and Precautions
Air and foreign matter in the refrigerant circuit can
cause abnormal rises in pressure, which can damage
the air conditioner, reduce its efficiency, and cause
injury. Use a vacuum pump and manifold gauge to
evacuate the refrigerant circuit, removing any
non-condensable gas and moisture from the system.
Evacuation should be performed upon initial
installation and when unit is relocated.
BEFORE PERFORMING EVACUATION
Check to make sure the connective pipes
between the indoor and outdoor units
are connected properly .
Check to make sure all wiring is connected
properly.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The standard pipe length varies
according to local regulations. In other areas, the standard pipe length is 5m (16‘). The refrigerant
should be charged from the service
port
on the outdoor unit’s low pressure valve.
The additional
refrigerant to be charged can be calculated using the following formula:
Liquid Side Diameter
R-32 : (Total pipe length -
standard pipe length)x
12g(0.13oZ)/m(ft)
(Total pipe length -
standard pipe length)x
24g(0.26oZ)/m(ft)
