B. Piping
1. Before installing, blow out pipe line to remove scale
and other foreign matter.
2. Mounting (Grades A, B, C, E, F) - mount so that inlet
and outlet connections are horizontal (filter bowl
vertical) to ensure proper liquid drainage.
3. Flow Direction - install so that the air flow is in the
direction indicated on filter.
NOTE: Grade D flows from outside to inside of element.
All other grades flow from inside to outside. Observe
flow arrows on unit.
4. Isolation valves and by-pass piping - For ease of
service, isolation and by-pass valves are desirable. In
critical applications, two filters installed in parallel may
be necessary to avoid interruption of air supply.
C. Drain Provisions (Grades A, B, C, E, F) - The bottom of
the pressure vessel is provided with a drain plug for
shipping purposes. Provision for manual or automatic
draining is necessary for proper operation.
Do not attempt to remove drain plug if
the unit is pressurized.
1. Manual Drain - When draining is performed manually
on a regular, periodic basis, a simple (open/shut) valve
may be used to drain the vessel. When draining
manually, the valve should be opened slowly to avoid
rapid depressurization and possible element damage.
2. Automatic Drain - Where regular manual draining is
not performed, an automatic condensate drain
should be used. A variety of drains is available from
the manufacturer.
