INSTALLATION INSTRUCTIONS
Your air conditioner is designed to install in standard double hung windows with opening widths of
22 to 36 inches(559mm to 914mm) (See Fig.1).
Lower sash must open sufficiently to allow a clear vertical
opening of 14-1/2 inches (368mm). Side louvers and the rear
of the AC must have clear air space to allow enough airflow
through the condenser, for heat removal. The rear of the unit
must be outdoors, not inside a building or garage.
NOTE: Save Carton and these Installation Instructions
for future reference. The carton is the best way to store unit
during winter, or when not in use.
