APPLICATION DATA

Condensate trap — A 2-in. (51 mm) condensate trap must be field supplied.

1” (25mm) MIN.

TRAP OUTLET

2” (50mm) MIN.

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. Remove the inserts similar to removing an electrical knock-out. Leave on duct covers to seal the horizontal discharge openings in the unit. Units installed in horizontal discharge orientation do not require duct cov- ers.

Minimum cooling ambient operating temperature — All stan- dard units have a minimum ambient operating temperature of 55°F (12.7°C). With low-ambient cooling enabled at the UI, units can op- erate at temperatures down to 0°F (-17.7°C).

Maximum operating outdoor air temperature — Maximum out- door operating air temperature for cooling is 125°F (51.6°C).
