Condensate Drains
Make drain connection to the 1” N.P.T. drain coupling
provided on unit.
Note - The drain pan is made with a glass reinforced
engineered plastic capable of withstanding typical joint
torque but can be damaged with excessive force. Tighten
pipe nipple hand tight and turn an additional quarter turn.
A trap must be installed between drain connection and an
open vent for proper condensate removal. See figure 3 or
4. It is sometimes acceptable to drain condensate onto
the roof or grade; however, a tee should be fitted to the
trap to direct condensate downward. The condensate line
must be vented. Check local codes concerning
condensate disposal. Refer to pages 2 and 3 for
condensate drain location.
Units are shipped with the drain coupling facing the front
of the unit. Condensate can be drained from the back or
bottom of the unit with the following modifications. The
unit can be installed in either downflow or horizontal air
discharge regardless of condensate drain location.
