Horizontal drainage pipes must be inclined so that air could escape from
UA
D and that debris is flushed
toward
UA
D (left). When horizontal drainge pipes are long, venting should be built (right).
If if the bottom connection is used, the height of
the upper connection must be lower than the
lowest point of the condensate level. Upper
unused connection must be properly sealed
(pluged).
Use upper connection to mount venting line back
to pressure equipment (e.g. pressure vessel).
Venting line prevents creation of air bubbles
assuring constant flow of condensate into the
drain.
Venting is made by T-piece.
The T-piece should be located just infront of valve
so that path from the
UA
D tank to the venting
piece is as short as possible to prevent
compressed air from being trapped in the tank.
Venting with T-piece can only be used with
upper inlet connection.
Venting is made through auxiliary inlet.
UA
D has provisions for building an auxiliary inlet
where venting could be connected. This auxuliary
inlet is not implemented in the standard
UA
D.
Conntact manufacturer for more
information about
UA
D with the auxiliary inlet.
