Fan Cycle Switch
The Fan Cycle Switch is located under the control panel
behind the front grille. This switch is set to CONT at the
factory to provide continuous fan operation in cool or
heat modes. Leaving the switch at the CONT setting
allows continuous circulation of room air and will keep
the room temperature at stable condition. If you want the
fan to cycle on and off with the compressor or electrical
heater, set the switch to CYCLE.

Freeze Protection
Freeze Protection helps prevent plumbing damage due to
sub-freezing temperatures — even if you have turned the
mode selector switch to OFF. The unit automatically turns
on the heater and fan if the room temperature falls to
about 46°F.
You do not have to do anything to activate the Freeze
Protection. It will work as long as power to the unit has
not been interrupted.
Care and Cleaning
Turn off the air conditioner before cleaning.
Air Filters
The air filters should be cleaned at least once every two
weeks. Clogged filters reduce cooling, heating and air
flow.
Keeping these filters clean will:
• Decrease cost of operation.
• Save energy.
• Prevent clogged heat exchanger coils.
• Reduce costly compressor problems.
To remove the air filters:
Pull up
2 air filters
Front
To clean the air filters:
• Vacuum off heavy dirt.
• Run water through the filters.
• Dry thoroughly before replacing.
To reinstall the air filters:
Push
down
Do not operate the air conditioner without the filters in
place. If a filter becomes torn or damaged it should be
replaced immediately. Operating the unit without the fil-
ters in place or with damaged filters will allow dirt and
dust to reach the indoor coil and reduce the efficiency of
the unit.
Replacement filters (STK01AF) are available from the deal-
er or installer.
