Condensate Drain Lines - Goodman AVPTC 14 Series Installation & Operating Instructions Manual

NOTE: In situations where the TXV must be removed and
replaced or re-installed into the system, the TXV should be
hand tightened first and then apply a half turn to fully set the
TXV. No more than 20 ft-lb torque should be applied to the
joints of the TXV.

8 Condensate Drain Lines

The coil drain pan has a primary and a secondary drain with
3/4" NPT female connections. The connectors required are
3/4" NPT male, either PVC or metal pipe, and should be hand
tightened to a torque of no more than 37 in-lbs. to prevent
damage to the drain pan connection. An insertion depth of
approximately 3/8" to 1/2" (3-5 turns) should be expected at
this torque.
1. Ensure drain pan hole is not obstructed.
2. To prevent potential sweating and dripping on to fin-
ished space, it may be necessary to insulate the con-
densate drain line located inside the building. Use Ar-
maflex or similar material.
®
A secondary condensate drain connection has been
provided for areas where the building codes require it.
Pitch all drain lines a minimum of 1/4" per foot to provide
free drainage. Provide required support to the drain line to
prevent bowing. If the secondary drain line is required, run
the line separately from the primary drain and end it where
condensate discharge can be easily seen.
