(See Figure 26)
FILTER ALERT light will come on after 250 hours of use. Touch
FILTER ALERT to reset.
TO SET MODE OF OPERATION
When unit is first turned on, it will be in the COOL mode (light
on), with constant fan.
Touch MONEYSAVER (light on) to activate the MoneySaver
feature. (MoneySaver is a feature that cycles the fan with the
compressor so that the fan does not run all the time. This
saves energy and improves dehumidification.) If customer
prefers a constant fan for more air movement, touch
MONEYSAVER again and unit will return to constant fan.
Touch FAN ONLY (light on) and only the fan will run. This
feature may be used in conjunction with the FRESH AIR/
EXHAUST lever to bring outside air into a room, or to exhaust
stale air.

TO ADJUST TEMPERATURE

TO ACTIVATE SMART FAN
Touch SMART FAN (light on). Smart Fan will adjust the fan
speed automatically to maintain the desired comfort level. For
example, if the outside doors in the home are open for an
extended period of time, or more people enter a room, Smart
Fan may adjust to a higher fan speed to compensate for the

speed on your own, or from having to change the desired
temperature you have selected. Smart Fan will also run to
test temperature if the off cycle is long.
