The units were designed for residential, light commercial and commercial applications. They can easily be installed on a roof curb, slab, roof jack or frame.
All units are
The units are available in cooling only, and cooling with gas heat. Electric heaters are available as
Both bottom and side duct connections are available without having to swap panels. The installer simply removes the duct covers for the desired configuration. Economizers may be used on either bottom and side duct applications with no modifications required.

FEATURES
COMMON FOOTPRINT/COMMON CABINET - All model sizes and configurations share a common cabinet and a com- mon roof curb. The installer has the flexibility of setting one curb and placing the proper tonnage unit on that curb after the internal load has been determined. He can even decide between gas or electric heat after the curb has been set.
HIGH EFFICIENCY - Units have a high cooling efficiency of as high as 13.2 SEER and gas / electric models have a mini- mum AFUE of 80.3%. All efficiencies exceed legislated mini- mum levels and provide low operating costs.
CONVERTIBLE AIRFLOW DESIGN - Both the side and bot- tom duct openings are covered when they leave the factory. If a side supply / side return is desired, you simply remove the two side duct covers from the outside of the unit and discard them. If a bottom supply / bottom return is desired, you simply remove the two knockout panels from the base of the unit and discard them. No panel cutting or swapping is required! Con- vertible airflow design allows maximum field flexibility and minimum inventory.
damper and economizers simply slide in, and electrical con- nections are made by modular plugs. Electric heaters mount easily, and knockouts are provided in the internal partitions to connect the elements to the control box single point kit.
The motorized air damper includes a
The manual outdoor damper provides 0% through 35% or 0% through 100% of return air opening (field adjustable). Designed for duct mounted side or bottom supply/return applications. Includes rain hood assembly and filter.
The 14" high roof curb is shipped knocked down. An insu- lated deck is not required because the bottom of the unit is insulated.
Low ambient controls are available to provide stable unit operation at outdoor temperatures down to 0F.
Propane, high altitude and low NOx kits are also available to cover all gas heating applications.
WIDE RANGE OF INDOOR AIRFLOWS - All models operate over a wide range of design conditions with the use of
FULL PERIMETER BASE RAILS - The permanently attached base rails provide a solid foundation for the entire unit and protect the unit during shipment. The rails provide fork lift access from 3 sides, and rigging holes are also provided so that an overhead crane can be used to place the units on a roof.
SYSTEM PROTECTION - Internal overload protection is standard on all compressors. Every unit has a liquid line filter-
UTILITY CONNECTIONS MADE EASY - Gas and electric utility knockouts are provided in the unit base as well as the side of the unit. A clearly identified location is provided to mount a field supplied electrical disconnect switch. Utility connections can be made quickly and with a minimum amount of field labor.
SIMPLE CONTROL CIRCUIT - A low voltage printed circuit board contains a compressor lockout indicator light and a low voltage terminal strip. An additional set of pin connectors is also provided to simplify the field interface of external con- trols.
