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 duct-
work to unit with flanges.
To convert a unit to downflow discharge or horizon-
tal discharge — Units are equipped with factory-installed
duct covers on both the downflow and horizontal openings.
Remove appropriate duct panel covers for intended dis-
charge application. Units with downflow option do not re-
quire duct panel cover removal.
Airflow — Units are draw-thru on cooling and blow-thru
on heating.
Maximum cooling airflow — To minimize the possibility
of condensate blow-off from evaporator, airflow through units
should not exceed 450 cfm/ton.
Minimum cooling airflow is 350 cfm/ton.
Minimum ambient operating temperature in cooling
for all standard units is 40 F. With accessory low ambient
temperature kit, units can operate at temperatures down to
0° F.
