Position the unit roof opening such that the supply
discharge and exhaust inlet of the unit will line up with
the corresponding ductwork. Be sure to allow for the
recommended service clearances when positioning
opening (see Service Clearances). Do not face the
outdoor air intake of the unit into prevailing wind and
keep the intake away from any other exhaust fans.
Likewise, position the exhaust discharge opening away
from outdoor air intakes of any other equipment.
