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 downflow
openings. Remove the inserts 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/ton.
Minimum cooling airflow — The minimum airflow is 350
cfm/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. With accessory low ambient temperature
kit, units can operate at temperatures down to 0°F.
Maximum cooling operating outdoor air temperature —
Maximum outdoor operating air temperature is 125°F.
