AIR HANDLERS

RHKL- SERIES

featuring Industry Standard
R-410A Refrigerant

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.

■ On-demand dehumidification terminal that adjusts airflow

to help control humidity for unsurpassed comfort in cool­ing mode.

■ External filter required.
