AIR CONDITIONER FEATURES (CONTINUED)
Additional things you should know
Now that you have mastered the operating procedure, here are more features in your control that 
you should become familiar with.
 The Cool circuit has an automatic 3 minute time delayed start if the unit is turned off and on
 quickly. This prevents overheating of the compressor and possible circuit breaker tripping.
 The fan will continue to run during this time.
 The control will maintain any set temperature within 2 F, between 60 F and 90 F degrees.
 The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius.
 To convert from one to the other, press and hold the UP and DOWN Temp/Timer buttons at the 
 same time, for 3 seconds.
Exhaust Control
 This Exhaust Control allows the air conditioner to either circulate inside air (Closed) or exhaust
 air to the outside (Open).
 The Closed position is used when maximum cooling is desired. It may also be used for air re-
 circulation without cooling when the air conditioner is set in any FAN position.
 The Open position removes stale air from the room and exhausts it to the outside. Fresh air is
 drawn in through normal passages in the home.
4-Way Louvers
 The 4-Way air directional louvers allow you to
 direct air flow up or down, left or right throughout
 the room as needed. To adjust the air directional 
 louvers side-to-side, use the center handle as 
 you move it side-to-side.
