Items with this warning sign concerning the product's safety and the personal security
must be performed strictly.
Items with this forbidding sign refer to absolutely forbidden behaviors. If not, they may
cause machine damage or endanger operator's personal safety.
Clean the lter regularly.
Cooling or heating performance will be degraded
if the lter is blocked, resulting in large power
consumption, failure, and water dripping
at freezing.
Regulating Wind Direction:
It is recommended not to make the wind
deector downwards for a long time to avoid
condensation at air outlet port during refrigerating
or dehumidifying.
Water dropping might appear at the air outlet port
in refrigerating or dehumidifying mode.
The machine operation must be controlled by the
control.
Avoid cold wind from blowing out.
During heating running, the fan of indoor units
will not rotate immediately as to prevent cold wind
from blowing out.
Don't touch the outlet while the ap is moving.
Don't put anything in the grid in case danger may
occur.
Defrosting:
During heating running, the air conditioner would
defrost automatically if there is frost on heat
exchanger of outdoor units.
Do not rotate fans of both indoor units and
outdoor units during defrosting.
After nishing defrosting, the air conditioner will
resume running automatically.
Hints:
As air conditioners absorb heat from the
environment and release it to the room, heating
effects will be inuenced by the temperature in
and out of the room.
Changing Wind Speeds:
In the state of refrigerating, with automatic blowing
mode, the wind speed automatically decreases
when the room temperature approaches the
setting.
In the state of heating, when the room
temperature reaches the setting temperature the
compressor stops working and the fan turns to low
wind or stops. Wind speed changes automatically
in the dehumidifying mode.
