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).
