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
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
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

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.
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 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.
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.

REFRIGERANT PIPING CONNECTION

When connecting refrigerant piping, do not let substances or gases other than the specified refrigerant enter the unit. The presence of other gases or substances will lower the unit’s capacity, and can cause abnormally high pressure in the refrigeration cycle. This can cause explosion and injury.
Note on Pipe Length
The length of refrigerant piping will affect the performance and energy efficiency of the unit. Nominal efficiency is tested on units with a pipe length of 5 meters (16.5ft)( In North America, the standard pipe length is 7.5m (25′)). A minimum pipe run of 3 metres is required to minimise vibration & excessive noise. For the R290 refrigerant models, no refrigerant can be added and the maximum length of refrigerant pipe should not exceed 5 meters(16.5ft). Refer to the table below for specifications on the maximum length and drop height of piping.

AIR EVACUATION

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 noncondensable 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.

8. If there is a change in system pressure, refer to Gas Leak Check section for information on how to check for leaks. If there is no change in system pressure, unscrew the cap from the packed valve (high pressure valve).
9. Insert hexagonal wrench into the packed valve (high pressure valve) and open the valve by turning the wrench in a 1/4 counterclockwise turn. Listen for gas to exit the system, then close the valve after 5 seconds.
10. Watch the Pressure Gauge for one minute to make sure that there is no change in pressure. The Pressure Gauge should read slightly higher than atmospheric pressure.
11. Remove the charge hose from the service port.
