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.
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 (10) at
top of filter on the cover assembly (5) one and one-half turns.
7.2
Open one or both drain plugs (11) on bottom of filter head and
drain housing. Reinstall and tighten drain plug(s).
7.3
Manually turn filter housing handle counter-clockwise to
remove cover assembly. No tools should be needed or used
to remove the cover assembly.
Note: The UR619/699C series assembly is equipped with an
extraction mechanism within the cover assembly. Turn the cover
handle counterclockwise until handle threads disengage then lift
the cover slightly to pull the element free from its cage. Releasing
the tension on the cover will allow "retraction spring clips"
(located in the cover assembly) to return to their free position.
Cover can now be removed, making the element accessible.
7.4
Remove filter element (8) 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 (6a). 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 (5) 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 (6b)
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.
