APPLICATION DATA
Condensate trap A 2-in. condensate trap must be eld
supplied.
Ductwork Secure downow discharge ductwork to roof
curb. For horizontal discharge applications, attach
ductwork to unit with anges.
To convert a unit to downow discharge Units are
equipped with factory-installed inserts in the down-ow
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 airow To minimize the possibility
of condensate blow-off from the evaporator, airow
through the units should not exceed 450 cfm per ton.
Minimum cooling airow The minimum cooling
airow 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.
