Condensate Drains
Remove cap and make drain connection to the 1”
N.P.T. drain coupling provided on unit. A trap must be
installed between drain connection and an open vent
for proper condensate removal. See figure 3. 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, 3 and 4 for
condensate drain location.
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.
