Air Evacuation
NOTE : 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 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. 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. For the R290
refrigerant models, no refrigerant can be added. The additional refrigerant to
be charged can be calculated using the following formula:

· Active Clean function(some units)
— The Active Clean Technology washes away dust when it adheres to the heat
exchanger by automatically freezing and then rapidly thawing the frost. A “pi-
pi” sound will be heard. The Active clean operation is used to produce more
condensed water to improve the cleaning effect, and the cold air will blow
out. After cleaning, the internal wind wheel then keeps operating with hot air
to blow-dry the evaporator, thus keeping the inside clean.
— When this function is turned on, the indoor unit display window appears “CL
” , after 20 to 130 minutes, the unit will turn off automatically and cancel
Active Clean function.
— For some units, the system will start hightemperature cleaning process, and
the temperature of air outlet is very high. Please keep away from it. And this
would lead to the rising of the room temperature .
Louver Angle Memory
When turning on your unit, the louver will automatically resume its former
angle.
Refrigerant Leakage Detection
The indoor unit will automatically display “EC” or “EL0C”or flash LEDS (model
dependent ) when it detects refrigerant leakage.

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.
The indoor unit emits white mist
Both the indoor and outdoor units emit white mist
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.
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.
Low hissing sound during operation: This is normal and is caused by refrigerant gas flowing through both indoor and outdoor units.
Both the indoor unit and outdoor unit make noises
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
