IMPORTANT SAFETY PRECAUTIONS
Improper handling can cause serious damage or injury. Please read the following safety
information in its entirety.
Operation, Cleaning, and Maintenance Safety Precautions
• Children and people with reduced physical, sensory, or mental capabilities, or lack of
experience and knowledge, should only use this air conditioner if they are given supervision or
instructions concerning use of the air conditioner in a safe way and understand the hazards
involved.
• Children should not play with the air conditioner.
• Never stick fingers or any other body parts into the air conditioner openings. The internal fan
may be rotating at high speeds, and may result in injury.
• After removing the filter, do not touch the fins in order to avoid injury.
• Maintenance must be performed by qualified professionals. Otherwise, you may experience
personal injury or damage to the air conditioner and surrounding property.
• Do not repair the air conditioner by yourself. It may cause electric shock or damage. Please
contact a qualified service representative when you need to repair the air conditioner.
• Do not block the air outlet or air inlet. This could cause a malfunction.
• Do not spill water on the remote control as this can permanently damage the remote.
• If the below problems occur, please turn off the air conditioner and disconnect power at the
circuit breaker immediately. Then contact your dealer or a qualified professional for service.
• The power cord is overheating or damaged.
• There is an abnormal sound during operation.
• The circuit breaker trips frequently.
• The air conditioner gives off a burning smell.
• The indoor unit is leaking.
• If the air conditioner operates under abnormal conditions, it may cause malfunctions, electric
shock, or fire hazard.

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 changes from
COOL/HEAT mode to
FAN mode
The indoor unit emits
white mist
Both the indoor and
outdoor units emit
white mist
The indoor unit makes
noises
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 off.
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 off the compressor. The unit will continue operating when the
temperature fluctuates again.
In humid regions, a large temperature difference between the room’s
air and the conditioned air can cause white mist.
When the unit restarts in HEAT mode after defrosting, white mist may
be emitted due to moisture generated during the defrosting process.
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.
DURASTAR.COM

Page 20
ISSUE POSSIBLE CAUSES
Both the indoor unit
and outdoor unit make
noises
The outdoor unit
makes noises
Dust is emitted from
either the indoor or
outdoor unit
The unit emits a bad
odor
The fan of the outdoor
unit does not operate
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.
The unit will make different sounds based on its current operating
mode.
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 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.
During operation, the fan speed is controlled to optimize product
operation.
Operation is erratic,
unpredictable, or unit is
unresponsive
NOTE
If problem persists, contact a local dealer or your nearest customer service center.
Provide them with a detailed description of the unit malfunction as well as your model
number.
