2000 series convertible package rooftop models have two
independent refrigerant circuits for efficient part load operation.
Although the units are primarily designed for curb mounting on a roof,
they can also be slab-mounted at ground level or set on steel beams
above a finished roof.
Cooling only, cooling with gas heat and cooling with electric heat
models are available with wide variety of factory-mounted options
and field-installed accessories to make them suitable for almost
every application.
All units are self-contained and assembled on full perimeter base
rails with holes in the four corners for overhead rigging.
Every unit is completely piped, wired, charged and tested at the fac-
tory to simplify the field installation and to provide years of depend-
able operation. Powder paint cabinets provide an exceptionally
durable finish with the 750 hour salt spray process per ASTM-B117
test standard.
All models (including those with an economizer) are suitable for
either bottom or horizontal duct connections. Models with power
exhaust are suitable for bottom duct connections only. For bottom
duct, remove the sheet metal panels from the supply and return air
openings through the base of the unit. For horizontal duct, replace
the supply and return air panels on the rear of the unit with a side
duct flange accessory.
All models are available with three different outdoor air damper
options:
•
Single enthalpy economizer
•
Single enthalpy economizer with power exhaust
•
Motorized outdoor air damper
The enthalpy system contains one sensor that monitors the outdoor
air and determines when the air is cool enough and dry enough to
provide "free" cooling.
The rainhood is painted to match the basic unit and must be field-
assembled before installing.
Power exhaust is not available as a field installed option.
