       PERFORMANCE

Three-minute protection feature

A  protection  feature  prevents  the  air  conditioner  from  being 

activated for approximately 3 minutes when it restarts immedi-

ately after operation.

with the power again. Push the ON/OFF button on the remote 

controller to restart operation.

4.    HINTS FOR ECONOMICAL OPERATION

Adjust the air flow direction properly to avoid winding toward 

your body.

Adjust the room temperature properly to get a comfortable 

situation and to avoid supercooling and superheat.

 

In cooling, close the curtains to avoid direct sunlight.

To keep cool or warm air in the room, never open doors or 

windows more often than necessary.

Set the timer for the desired operating time.

Never put obstructions near the air outlet or the air inlet. Or it 

will cause lower efficiency, even a sudden stop.

The following should be noticed to ensure an economical operation. 

(Refer to corresponding chapterfor details)

If you don't plan to use the unit for a long time, please discon-

nect power and remove the batteries from the remote control-

ler. When the power switch is connected, some energy will be 

consumed,  even  if  the  air  conditioner  isn't  in  operation.  So 

please  disconnect  the  power  to  save  energy.  And  please 

switch  the  power  on  12  hours  before  you  restart  the  unit  to 

ensure a smooth operation.

A  clogged  air  filter  will  reduce  cooling  or  heating  efficiency, 

please clean it once two weeks.
