Vent Control   
The vent control is located above the control knobs. The operation method is different on different models (see 
the following figures). 
For maximum cooling efficiency, CLOSE the vent. This will allow internal air circulation.   
OPEN the vent to discharge stale air.

Vertical airflow adjustment 
For the units with AUTO SWING feature (automatically)(on some models): 
                                               
When the AUTO SWING switch is turned to ON position, the vertical louvers 
automatically oscillate right and left sweeping the cold air alternately to obtain 
comfortable cooling. The vertical louvers may be stopped at any position when the 
AUTO SWING switch is turned “OFF”. 
 
For the units without AUTO SWING feature (manually): 
To adjust vertical airflow direction, move the lever gently to the left or right by hand 
until the desired horizontal airflow direction is obtained. 
NOTE: Only For the units with hand-operating lever. 
 
 
  Horizontal air flow adjustment (manually) 
To adjust vertical air flow direction of the up or low horizontal louvers, adjust 
any one of the up or low horizontal louver blades. 
 
 
 
 
To open the vent, set the lever to the right position. 
To close it, set the lever in the left position.
