8.Heating operation (heat pump type )
During the heating operation ,the heat pump airconditioner operates with the princ iple of
absorbing heat from outdoor and release heat into indoor. When the outdoor temperature falls,
the heating capacity decrease accordingly because the heat absorbed from outdoor decreases
(See the figure on the right).At the same time, the
temperature difference between indoors and outdoors
is enlarged, so that the heating load increase accordingly.
If the air-conditioner can not reach a satisfactory effect,
it is recommended that other heating devices beused
together.

7.If you select the cooling operation in a relatively damp environment (relative humidity is higher
than 80%),dew may be formed over the surface of indoor unit and drop. In such a case, please
adjust the vertical wind vanes to its maximum ventilation Position and choose
high to reduce
the dew.
2.White steam comes out from the indoor unit
The fan of the indoor and outdoor unit will stop under frost dissolving operation.
The time for frost dissolving varies in range of 4 to 10 minutes according to the out-door
temperature and the frost extent.
It is normal phenomenon that there may be steam coming out from the outdoor unit during
the frost dissolving operation.
During the cooling operation ,under high relative humidity indoors, white steam may come out
due to the high humidity and temperature difference of air inlet and outlet. The air-conditioner
convert to heating operation after the frost dissolving, the moisture due to frost dissolving is
discharged in form of steam.
3.High noise during operation
4.Dust is blown out from the indoor unit
5.The peculiar smell emanates from indoor unit
6.Cooling /Heating (not for cold wind type) operation converts to only wind mode.
When the air-conditioner uses the first time after being left unused for a long time,the dust
inside the indoor unit will be blown out.
The s ell which absorbed from room, furniture, clothing or cigarette emanates during the
air-conditioner is operating. m
When the indoor unit reaches the stip lated temperature, the air-conditioner will stop the
operation of compressor and convert to only wind mode. The compressor will restart cooling
or heating after the room temperature rise or drop to a certain degree. u
When the compressor is operating or just stops running, fizzle may be heard because of the
refrigerant flow or stop flowing.
After the air-conditioner operates or stops for a while, crackle from the naturel expansion and
contraction of the plastic components may be heard because of temperature variation.
When the air-conditioner is energized for the first time, sound from friction may be heard
because of the reposition rotating of wind wave.
