Refrigeration System
Condensate Drain Connections
All condensate drain connections must be connected to the
evaporator drain connections.
A condensate trap must be installed due to the drain
connection being on the “negative pressure” side of the
fan. Install the P-Traps at the unit using the guidelines in
Figure 22.

Female Connection
Pitch the drain lines at least 1/2 inch for every 10 feet of
horizontal run to assure proper condensate flow. Do not
allow the horizontal run to sag causing a possible double-
trap condition which could result in condensate backup due
to “air lock”.
