■ Includes an energy efficient GE

ECM

Motor, which in

most applications, enhances the SEER rating of the out-

door unit. It also slowly ramps its speed up for quiet oper-

ation 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.

Airflow Performance Airflow performance data is based on cooling performance with a coil and no filter in place. Select performance table for appropriate unit size, voltage and number of electric heaters to be used. Make sure external static applied to unit allows operation within the minimum and maximum limits shown in table below for both cooling and electric heat operation. For optimum blower performance, operate the unit in the .1 [2.54 mm] to 1.00 inches [25.4 mm] W.C. external static range.
