7 Filter element servicing
During servicing, the external surfaces of the filter assembly
must be cleaned to remove any dust deposits.
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.
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.
Refer to Service Parts List (Section 9) 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
(5) at top of filter one and one-half turns.
WARNING:
FAILURE TO DEPRESSURISE THE FILTER
BEFORE SERVICING ELEMENT COULD RESULT
IN EXPLOSIVE LOSS OF FLUID, DAMAGE TO
EQUIPMENT AND POSSIBLE PERSONAL INJURY.
7.2 Open drain plug (5) at the bottom of the bowl and drain
fluid from the bowl into a suitable waste receptacle.
Replace and torque tighten drain plug to 12 ft/lb or 16 Nm.
Unscrew and remove the bowl (2) from head (1) counter-
clockwise when viewed from below.
7.3 Element replacement (UE210 Series): Remove filter
element (8), if already fitted, and carefully inspect the
interior surface (flow through the element is in-to-out) for
visible contamination. Normally no dirt should show, but
visible dirt or particles can be an early warning of system
component failure. Discard both the filter element
and its O-ring. 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.
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.

7.4 DO NOT run the system without a filter element
installed. Check that the O-ring (3) between the bowl (2)
and head (1) is not damaged. Use the replacement filter
as indicated by the part number on the element endcap.
7.5 Lubricate element O-ring with clean system fluid.
Reinstall element in the shell assembly. Lightly lubricate
bowl to head O-ring with clean system fluid and
reassemble the housing until thread bottoms. Tighten to
10-14LBFT (13-19Nm).
7.6 Bleed the filter by filling the filter until all air bleeds
through the vent plug(7), then torque tighten the vent
plug to 12 lb/ft or 16Nm. Check for leaks as per
section 4.8.
7.7 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
again as per section 6.
