7.4 DO NOT run the system without a filter element
installed. Check that the O-ring 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
head-to-bowl O-ring with clean system fluid and
reassemble the housing until thread bottoms.
The bowl should be torque tightened using a suitable
socket wrench to 74 ft/lb or 100 Nm.
O-ring sealing is not improved by over tightening
7.6 Bleed the system and check for leaks as per section 5.2.
7.7 After element change ENSURE DIFFERENTIAL
PRESSURE DEVICE IS RESET BY PUSHING IN THE
RED BUTTON; electrical switches reset automatically.
When system reaches normal operating temperature,
check that the electrical switch has not actuated and/or
the visual warning button has remained depressed. If
visual indicator rises due to a cold start condition, reset
again as per section 6.
8 Fluid Sampling
Optimum sampling to verify fluid condition can be achieved
by the use of sampling adaptors installed in place of or in
combination with the differential pressure device. For more
information consult Pall or your local Pall Distributor.
Pall offers a fluid contamination analysis service – consult the

7 Filter element installation / 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.
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.
7.2 Unscrew and remove the filter bowl assembly (2) from
head (1) counter-clockwise when viewed from below. It
will be necessary to use a 1" socket wrench on the
hexagon on the bowl to initially loosen the bowl.
7.3 Element replacement (UE209 Series): Remove filter
element (5), 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:
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.
