Troubles not concerning air conditioner

If any of the following conditions occurs, you air conditioner is in order.
(1) Common protection for compressor.
Protection for compressor you can't start compressor within 3 minutes.
•
Warm air control (cooling and heating type).
Under the HEAT mode, the indoor fan speed is automatically reduced or stopped to prevent a cold draft if the set temperature
of the indoor heat exchanger has not been reached under the following three situations:
Just start heating operation.
Defrosting.
Heating in a low temperature.
• Defrosting (cooling and heating type).
Frost may be generated on Outdoor Heat Exchanger when outdoor temperature is low and humidity is high, It would lower heating
efficiency of the conditioner, The air conditioner would stop heating operation and start defrosting automatically, After finishing the
defrosting, it will restart heating operation.
The fans in both the indoor and the outdoor units will stop running during defrosting operation.
The time of defrosting is different according to the outdoor temperature and frost degree. (For approximately 4~10 minutes).
During defrosting, white smog may be come out from outdoor unit. This is caused by quickly frosted and it's a normal case.
(2) White smog discharged from indoor unit.
When running under "cooling" mode at the place with high humidity, white smog may come into being because of high humidity
•
and high difference in temperature.
When the air conditioner finish the defrosting, it will automatically turn to heating operation, the water produced during defros-
•
ting will change into smog and come out from indoor unit.
(3) Low noise of air conditioner.
• When air conditioner is in "Automatic", "Cooling" ,"Dehumidifying" or "Heating" operating, there may be some "ss" sound cau-
sed by the flowing between indoor and outdoor unit of refrigerant.
• After air conditioner starting or stopping for a short while there may be some "zz" sound caused by natural expansion or shrin-
kage of plastic parts because of the temperature change.
• At the first time to connect the power supply, there may be some noise caused by the louvers turning to its original position.
(4) Dust blowing from indoor unit.
After being left unused for long time the dust may blow out from indoor unit if it is operated again.
•
(5) Odor from indoor unit.
• The indoor unit absorbs odor of room, furniture or cigarette and emanates them during operation.
(6) "Cooling" and "Heating" mode turned to "Fan" (Cooling only type without.
If the indoor temperature falls to set one, the air conditioner controller will stop compressor from running automatically and con-
•
vert to "Fan" mode. When the temperature rises or reduces to a certain value, the compressor will restart and the unit will get right.
(7) Heating capacity (cooling and heating type).
In the heating operation, heat is absorbed from outdoor and released into the room. That is so-called heat pump system.
• When the outdoor temperature is too low, heat absorbed from outdoor reduced and will result in reduced heating capacity (see
the right picture). There is a big difference in temperature between indoor and outdoor, and this will increase the heating load. In this
case, you are recommended to use another heating apparatus in combination with the air conditioner.
(8) Operation mode selection.
• While simultaneously operating both indoor units, the secondary unit can not
be operated in a mode conflicting to that of the primary unit. The unit initially star-
ted should be considered as the primary unit. In the circumstance that the opera-
ble modes are conflicting with each other, the TIMER lamp and DEF lamp located
on the display panel of the secondary unit will flash at a rate of 5 times per second.
This can be rectified through changing the operable mode of the conflicting unit.
