APPLICATION DATA
Condensate trap — A 2-in. condensate trap must be field
supplied.
Ductwork — Secure downflow discharge ductwork to roof
curb. For horizontal discharge applications, attach
ductwork to unit with flanges.
To convert a unit to downflow discharge — Units are
equipped with factory-installed inserts in the down-flow
openings. Removal of the inserts is similar to removing an
electrical knock-out. The unit is factory equipped with duct
covers to seal the horizontal discharge openings in the
unit. Units installed in horizontal discharge orientation do
not require duct covers.
Maximum cooling airflow — To minimize the possibility
of condensate blow-off from the evaporator, airflow
through the units should not exceed 450 cfm per ton.
Minimum cooling airflow — The minimum cooling
airflow is 350 cfm per ton.
Minimum cooling ambient operating temperature — All
standard units have a minimum cooling ambient operating
temperature of 55°F. With accessory low ambient
temperature kit, units can operate at temperatures down to
0°F.
Maximum operating outdoor air temperature — for
cooling is 125°F.
