3 FUNCTION
Function Description
OPERATING EFFICIENCY All units provide high operating efciencies and have a minimum EER of 8 or above.
ON SITE FLEXIBILITY
The series of model are divided into several sizes, which approximate tons share a common,
compact design cabinet with a single footprint. The installer has the exibility of setting one curb
and placing the proper tonnage unit on that curb after the standard load has been determined.
CONVERTIBLE
AIRFLOW DESIGN
The Bottom duct openings are covered when they leave the factory ready to be used for a
side supply / side return application. If a bottom supply / bottom return application is desired,
you simply remove the two panels from the bottom of the unit and place them in the side
supply / side return duct openings. No panel cutting is required and no accessory panel is
necessary. Convertible airow design allows maximum eld exibility and minimum inventory.
EXCLUSIVE COIL DESIGN Grooved copper tubes and enhanced aluminum n construction
improves heat transfer for maximum efciency and durability.
TOP DISCHARGE
The top discharge condenser fan does not disrupt neighboring areas and does not dry-out
vegetation surrounding the unit. The warm air from the top mounted fan is blown up away from
the structure and any landscaping. This allows compact location on multi-unit applications.
LOW OPERATING
SOUND LEVEL
The upward air ow carries the normal operating noise up and away from
the living area. The rigid and unique shock absorption structure greatly
reduces the vibration and effectively isolates motor sound.
SPACE SAVING With compact and unitary structure, the unit can be connected and assembled at
eld, which is in favor of transport and installation and saves indoor space.
