Ductwork Ð Secure down¯ow discharge ductwork to roof curb. For horizontal discharge applications, attach duct- work to unit with ¯anges.

To convert a unit to down¯ow discharge or horizon- tal discharge Ð Units are equipped with factory-installed duct covers on both the down¯ow and horizontal openings. Remove appropriate duct panel covers for intended dis- charge application. Units with down¯ow option do not re- quire duct panel cover removal.

Air¯ow Ð Units are draw-thru on cooling and blow-thru on heating.

Maximum cooling air¯ow Ð To minimize the possibility of condensate blow-off from evaporator, air¯ow through units should not exceed 450 cfm/ton.

Minimum cooling air¯ow is 350 cfm/ton.

Minimum ambient operating temperature in cooling for all standard units is 40 F. With accessory low ambient temperature kit, units can operate at temperatures down to 0° F.
