if the air conditioner is subject to abnormal  inter-
ference or frequent switch of functions. To resume 
normal  operation,  just pull out the power and reinsert 
it properly.

  Check, if remote controller is damaged. 

Water leaks from indoor unit. 

 Air 

humidity 

is 

too 

high. 

 Condensing 

water 

overflows. 

  Joint of indoor unit drain pipe is loose. 

Water leaks from outdoor unit. 

  Under cooling mode, water might condense 

  on pipe or pipe joint due to cooling. 

 Defrosted 

water 

flows

or 

defrost 

(auto defrost) mode. 

  Under cooling mode, water attached on heat 

exchanger will drip. 

No air blows out from indoor unit. 

  When the temperature of indoor heat exchanger is 

low during heating process, the indoor  unit will stop 
air blowing to prevent blowing of cold air (within 3 
minutes). 

  In HEAT mode: when outdoor temperature is low or 

humidity is high and much frost on the heat 
exchanger has developed, unit switches into 
automatic defrost mode. Indoor unit stops blowing air 
for 3-12 min. During this water may flow out or steam 
will appear 

  Under dehumidify  mode, the fan of  indoor unit might 

be stopped sometimes to prevent evaporation of 
condensing water and inhibit the rise of temperature 

Moisture exists on outlet grill. 
 

  lf the air conditioning is long running under high 

humidity, moisture might condense on the grill and
