Features
■ Includes an energy efficient GE
®
ECM®Motor, which in
most applications, enhances the SEER rating of the outdoor unit. It also slowly ramps its speed up for quiet operation and enhanced customer satisfaction.
■ Versatile 4-way convertible design for upflow, downflow,
horizontal left and horizontal right applications.
■ Nominal airflow up to 1.0" external static pressure.
■ Factory-installed high efficiency indoor coil.
■ Sturdy cabinet construction with 1.0 inch [25.4 mm] of
foil faced insulation for excellent sound and insulating
characteristics.
■ Field-installed auxiliary electric heater kits provide exact
heat for indoor comfort. Kits include circuit breakers which
meet U.L. and cUL requirements for service disconnect.
■ Dip switch settings for selectable, customized cooling air-
flow over a wide variety of applications.
