Bryant 582A manual Application Data

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.
