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 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. Use the duct cover supplied to seal the
horizontal discharge openings in the unit. Units installed
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.
MINIMUM COOLING AMBIENT OPERATING TEMPERA-
TURE — For all standard units the minimum ambient operating
temperature is 40°F. With accessory low ambient temperature
kit, units can operate at temperatures down to 0°F.
MINIMUM TEMPERATURE — Air entering the heat exchanger
in heating mode must be a minimum of 50°F continuous and/or
45°F intermittent.
