Mechanical Specification Options
GGeenneerraall
The Outdoor Units are fully charged from the factory for up to 15 feet of piping. This unit is
designed to operate at outdoor ambient temperatures as high as 115°F. Cooling capacities are
matched with a wide selection of air handlers and furnace coils that are AHRI certified. The unit is
certified to UL 1995. Exterior is designed for outdoor application.
CCaassiinngg
Unit casing is constructed of heavy gauge, galvanized steel and painted with a weather-resistant
powder paint finish on all louvered panels and the fan top panel. The corner panels are
prepainted. All panels are subjected to our 1,000 hour salt spray test . The base is made of a
CMBP-G30 weatherproof material to resist corrosion.
RReeffrriiggeerraanntt CCoonnttrroollss
Refrigeration system controls include condenser fan, compressor contactor and high pressure
switch. High and low pressure controls are inherent to the compressor. A factory supplied liquid
line drier is standard. Some models may require field installation.
CCoommpprreessssoorr
The compressor features internal over temperature, pressure protection and total dipped
hermetic motor. Other features include: Centrifugal oil pump and low vibration and noise.
CCoonnddeennsseerr CCooiill
The outdoor coil provides low airflow resistance and efficient heat transfer. The coil is protected
on all four sides by louvered panels.
LLooww AAmmbbiieenntt CCoooolliinngg
As manufactured, this system has a cooling capacity to 55°F. The addition of an evaporator
defrost control permits operation to 40°F. The addition of an evaporator defrost control with TXV
permits low ambient cooling to 30°F.
TThheerrmmoossttaattss—Cooling only and heat/cooling (manual and automatic change over). Sub-base to
match thermostat and locking thermostat cover.
EEvvaappoorraattoorr DDeeffrroosstt CCoonnttrrooll — See Low Ambient Cooling.
