its cage (shell) assembly (3). Reset the visual indicator, if
fitted, before refitting cover. Lightly lubricate cover O-ring
with clean system fluid, apply anti sieze (Loctite #39901
or equal) to tube threads to prevent galling and refit cover
assembly onto the tube. HAND TIGHTEN cover until
cover assembly and tube are bottomed together. O-ring
sealing is not improved by over tightening. USE A TOOL
(SOCKET OR BOX WRENCH NOT A PIPE WRENCH)
TO TIGHTEN COVER USING THE HEX TO PROPER
TORQUE OF 50-60 LBFT (68-81 Nm).

This allows clean pressurized fluid to fill the housing and
bleed off air.
7.8 Close vent plug on appearance of clear fluid. Check for
leaks.
7.9 After element change ENSURE DIFFERENTIAL
PRESSURE DEVICE IS RESET. Brass visual and
electrical and stainless steel electrical switches reset
automatically. When system reaches normal operating
temperature, check that the electrical switch and/or
visual warning button/flag has not actuated. If visual
indicator actuates due to a cold start condition, reset

Filter element servicing
During servicing, the external surfaces of the filter assembly
must be cleaned to remove any dust deposits including the
threads of the tube and cover.
Servicing must be conducted using suitable tools that do not
present a hazard.
Servicing must not be carried out when a potentially explosive
atmosphere is present.
Refer to Service Parts List (Section 10) for item numbers for
applicable replacement element series. Remove and replace
element as follows:
7.1 Turn off and depressurize the system. Open vent plug (9)
at top of filter on the cover assembly (4) one and one-
half turns.
7.2 Open one or both drain plugs (10) on bottom of filter head
and drain housing. Reinstall and tighten drain plug(s).
7.3 A tool (socket or box wrench not a pipe wrench) should
be used to remove the cover assembly by turning
counter clockwise.
NOTE: The UR610/690 series assembly is equipped with an
extraction mechanism within the cover assembly. Turn the
cover counterclockwise until cover threads disengage then lift
the cover to pull the element free from its cage. Cover can now
be removed, making the element accessible.
7.4 Remove filter element (7) and carefully inspect the
surface for visible contamination. Normally no dirt
should show, but visible dirt or particles can be an
early warning of system component breakdown and
can indicate potential failure. Discard both the filter
element and its O-ring (5a). The filter element is NOT
CLEANABLE. Any attempt to clean the filter element
can cause degradation of the filter medium and allow
contaminated fluid to pass through the filter element.
7.5 Inspect filter cover assembly (4) including threads for
possible damage or malfunction. Replace any damaged
parts. Remove any accumulated dirt. DO NOT run the
system without a filter element installed. Check that the
O-ring on the cover (5b) assembly is not damaged. Use
replacement filter element part number called for on
assembly nameplate.
WARNING:
FAILURE TO DEPRESSURISE THE FILTER
BEFORE SERVICING ELEMENT COULD RESULT
IN EXPLOSIVE LOSS OF FLUID, DAMAGE TO
EQUIPMENT AND POSSIBLE PERSONAL INJURY.
WARNING:
DO NOT ATTEMPT TO CLEAN OR RE-USE THE
ELEMENT.
ONLY USE GENUINE PALL REPLACEMENT FILTER
ELEMENTS. USE OF SUBSTITUTE ELEMENTS MAY
INVALIDATE PRODUCT WARRANTY.
CAUTION:
Filter elements should be replaced upon indication or
at specified intervals, six months maximum. Failure to
change the element will cause the filter to go on bypass.
WARNING:
FAILURE TO REPLACE DAMAGED PARTS IN FILTER
CAN CAUSE COMPONENTS IN THE SYSTEM TO FAIL
OR DEGRADE IN THEIR PERFORMANCE.
