FILTER
Before installing filter, check operating temperature and pres-
sure conditions to verify that they are within the specified
ranges. (See Operating Conditions on page 1). Also verify
that system flow rate corresponds to the rated capacity of
the filter. Operating at flows above rated capacity will result
in increased pressure drop.
Locate Filter at the point of lowest operating temperature to
ensure that water and oil vapor do not condense downstream
of the filter. Filter should be installed close to the point of
use to minimize the risk of pipe scale, dirt, etc. recontaminat-
ing the compressed air. This is particularly important when
installing a new filter on an existing system that has not had
proper filtration.
Install filter vertically. Provide required minimum clearance
below filter to allow for replacement of element.
(See Element Removal Clearance on page 2).
Protect filter from reverse flow conditions. Do not install filter
downstream of quick opening valves.
Remove filter head from the bowl by turning bowl counter-
clockwise. Pull element from locator. Set bowl and element
aside for use later.
Install inlet and outlet shutoff valves to facilitate replacement
of element. Bypass piping is recommended (See Figure 1A
and 1B). MAKE SURE VALVES ARE CLOSED BEFORE
PROCEEDING.
Connect filter head into piping. Avoid reducers or bushings to
match inlet size. The resulting restriction will increase pressure
drop. Make sure head is installed with flow arrows pointing
in proper direction. Use pipe thread compound as required.

IMPORTANT
INSTALL FILTER HEAD INTO THE PIPING WITH AR-
ROWS POINTING IN THE PROPER DIRECTION TO
ENSURE PROPER OPERATION. (SEE FLOW DIREC-
TION DIAGRAM BELOW).
Install element by pushing onto element locator on filter head.
Check to make sure that the o-ring in the head is in the proper
position. Thread filter bowl into filter head and tighten either
by hand (models F200-15 through 55) or with strap wrench
(models F200-85 through 1250). Do not over tighten. Overtight-
ening could damage filter bowl or make it difficult to remove.
Make sure drain valve on bottom of filter is closed. On filters
equipped with ADM2-2 auto drain, provide a drain line to
remove accumulated water and oil.
Pressurize system and slowly open inlet and outlet shutoff
valves.
Check piping for leaks. Depressurize system and repair leaks
as needed.
Re-pressurize system and slowly open inlet and outlet shutoff
valves. Close bypass valve if provided.
Filter is now in service.
