ADDITIONAL THINGS YOU SHOULD KNOW
Now that you understand the basic operation functions, here are more control features with which you should become
familiar.
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 the set temperature within 2 degrees Fahrenheit, between 60F and 90F degrees.
The control is capable of displaying temperature in degrees Fahrenheit or degrees Celsius. To convert from one to the
other and back, press and hold both the “TEMP/TIMER” Up( ) and Down ( ) buttons for 3 seconds.
When the unit is turned off in cool or energy saver mode, it will run in energy saver mode when it is turned on again, but
the setting of temperature and fan speed will remain.
Models with a key hole overflow drain hole can use drain kit 5304481680 to connect a 1/2 inch drain hose for safe
disposal of excess system water. This part can be ordered at www.SearsPartsDirect.com.
There is a 2-Second delay for the compressor shutting down when selecting FAN ONLY. This is to cover the possibility
of having to roll through to select another mode.
