APPLICATION DATA
1. CONDENSATE TRAP —A 2-in. condensate trap must be
field supplied.
2. DUCTWORK —Secure downflow discharge ductwork to
roof curb. For horizontal discharge applications, attach
ductwork to unit with flanges.
3. TO CONVERT A UNIT TO DOWNFLOW DISCHARGE —
Units are equipped with factory-installed inserts in the
down-flow openings. Remove the inserts similar to remov-
ing an electrical knock-out. Use an accessory duct cover to
seal the horizontal discharge openings in the unit. Units
installed in horizontal discharge orientation do not require
duct covers.
4. AIRFLOW —Units are draw-thru in the Cooling mode and
blow-thru in the Heating mode.
5. 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.
6. MINIMUM COOLING AIRFLOW —The minimum cooling
airflow is 350 cfm per ton.
7. MINIMUM AMBIENT COOLING OPERATION
TEMPERATURE
—For all standard units the minimum
ambient operating temperature is 55°F. With accessory low
ambient temperature kit, units can operate at temperatures
down to 0°F.
8. MINIMUM TEMPERATURE —Air entering the heat
exchanger in heating mode must be a minimum of 50°F
continuous and/or 45°F intermittent.
