Common Issues
The following problems are not a malfunction and in most situations will not require repairs.
Issue
Unit does not turn on when pressing ON/OFF button
Possible Causes
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.
Cooling and Heating Models: If the Operation light and PRE-DEF (Pre-heating/
Defrost) indicators are lit up, or the Operation light is lit up and the LCD
screen display “dF”, the outdoor temperature is too cold and the unit’s anti-
cold wind is activated in order to defrost the unit.
The unit changes from COOL mode to FAN mode
The indoor unit emits white mist Both the indoor and outdoor units emit white
mist
The indoor unit makes noises
Both the indoor unit and outdoor unit make noises
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 from the defrosting process.
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.
A squeaking sound may occur after running the unit in HEAT mode due to
expansion and contraction of the unit’s plastic parts.
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.
Page 15
Troubleshooting
Issue 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
Possible Causes
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.
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.

Note on Adding Refrigerant
Some systems require additional charging depending on pipe lengths. The
standard pipe length varies according to local regulations. For example, in
North America, the standard pipe length is 7.5m (25′). 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
R22 (orifice tube in the indoor unit):
6.35(1/4″)
9.52(3/8″)
12.7(1/2″)
(Total pipe length standard pipe length)x 30g (0.32oZ)/m(ft)
(Total pipe length standard pipe length)x 65g(0.69oZ)/m(ft)
(Total pipe length standard pipe length)x 115g(1.23oZ)/m(ft)
R22 (orifice tube in the outdoor unit):
(Total pipe length standard pipe length) x15g(0.16oZ)/m(ft)
(Total pipe length standard pipe length) x30(0.32oZ)/m(ft)
(Total pipe length standard pipe length) x60g(0.64oZ)/m(ft)
R410A: (orifice tube in the indoor unit):
(Total pipe length standard pipe length) x30g(0.32oZ)/m(ft)
(Total pipe length standard pipe length) x65g(0.69oZ)/m(ft)
(Total pipe length standard pipe length) x115g(1.23oZ)/m(ft)
R410A: (orifice tube in the outdoor unit):
R32 :
(Total pipe length standard pipe length) x15g(0.16oZ)/m(ft)
(Total pipe length standard pipe length) x30g(0.32oZ)/m(ft)
(Total pipe length standard pipe length) x65g(0.69oZ)/m(ft)
(Total pipe length standard pipe length)x 12g(0.13oZ)/m(ft)
(Total pipe length standard pipe length)x 24g(0.26oZ)/m(ft)
(Total pipe length standard pipe length)x 40g(0.42oZ)/m(ft)
CAUTION DO NOT mix refrigerant types.
Only for Australia models : · This unit contains factory charged refrigerant
covering 20m of refrigerant piping and additional
refrigerant charge on the installation site is not required for an
installation with up to 20m refrigerant piping. When refrigerant piping
exceeds 20m, additionally charge an amount calculated from the pipe length and
the above table for the portion in excess of 20m. · If an existing pipe system
is used, a required refrigerant charge volume will vary depending on the
liquid pipe size. Formula to calculate the volume of additional refrigerant
required Additional charge volume (kg) = { Main length (m) Factory charged
volume 20(m) } × 0.03(kg/m) · Make sure to remove the additional refrigerant
amount according to the nameplate rated charge (under 5m refrigerant piping )
under market or government verification testing .
