field supplied.
1” (25 mm) MIN.
2” (51 mm) MIN.

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 downflow openings. Removal
of the inserts is similar to removing an electrical knock--out. Leave
on 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 — Minimum cooling airflow is 350
cfm per ton for standard cooling modes. Airflow can be lower in
certain modes when humidity removal is an issue.
Minimum cooling operating outdoor air temperature — All
standard units have a minimum outdoor operating temperature of
55_F (13_C). With accessory low ambient temperature kit, units
can operate at temperatures down to 0_F (--17_C).
Maximum cooling operating outdoor air temperature —
Maximum outdoor operating air temperature is 125_F (52_C).
