F55 Series Particulate Filter
IS-F55
Installation
Before installing, blow out pipe line to remove scale and other
foreign matter. This unit has DRYSEAL pipe threads; use pipe
compound or tape sparingly to male threads only. Install units in
pipe line so that flow is in direction indicated by arrows on faces
of body. Install as near as possible to equipment being serviced.
Maintenance
To maintain maximum filtering efficiency, and to avoid excessive
pressure drop, the filter must be kept clean. On standard filters,
open drain cock (turn clockwise) periodically and drain off any
bowl accumulation before it reaches level of lower baffle. Bowl
drainage is automatic in the “Auto Drain” model; however, manual
draining can also be done. A visible coating of dirt or condensate
on the filter element surface, or an excessive pressure drop, is
an indication that cleaning is necessary.

Cleaning
To clean, it is not necessary to remove filter from the line.
Disassembly is simple and does not require tools. Use the
drawing on the reverse side of this sheet as a guide. Before
disassembly, shut off air supply and depressurize filter. Clean
all parts, except plastic bowl, with alcohol and blow out filter
body before reassembly. Wash filter element in alcohol and
blow out from the inside. Plastic bowls must be cleaned with
household soap only.
“Auto Drain” Operation
Auto Drain filters are equipped with a float actuated device
which automatically ejects liquid contaminants. If supplied in Kit
Form, Part No. RK602MD, the Auto Drain can be installed by
simply removing the bowl and then the bowl draincock. Insert
the Auto Drain in place of the removed draincock and reassemble
the unit in reverse order.
