To start unit

If your air conditioner is installed and plugged into a
properly grounded re cep ta cle, it is ready to op er ate.
Mode control
This dial allows you to select cooling at three different
speeds, as well as Fan Only.
Off- turns the unit off.
Hi Cool- for quick cooling.
Med Cool- to maintain a de sired temperature.
Lo Cool- when demand is low.
Sleep Setting- for night time use, or when demand is low.
Fan Only- will circulate air in the room without the
compressor coming on.
This setting can also be used with the EXHAUST air set ting
to remove stale air or smoke from the room; or it can be
used with the FRESH AIR setting to bring outside air into
the room. This is especially useful in the spring and fall
when cooling may not be nec es sary. The FRESH AIR and
EXHAUST controls are in the upper air discharge area.
The center po si tion of this control is the normal, or closed
position, which recirculates air for maximum performance
in the cool ing mode.

Temperature control

This dial is the thermostat. Turn it clock wise for cooler
temperature and counterclockwise for warmer.
Money Saver ® switch
This rocker switch can be depressed to ei ther Yes or No.
The Yes position provide the most economical op er a tion.
Both the fan and compressor will cycle on and off together,
main tain ing the selected temperature at a more constant
level and reducing the humidity more effi ciently. This
control will only operate when the unit is in a Cool mode.
In the No position, the fan will run constantly as long as the
unit is in the cooling mode.
