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.
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
For UR310 series (cover service):
Open vent plug (7) at the top of the filter one and
one-half turns.
Open drain plug (7b) on the filter head and drain fluid
into a suitable waste receptacle. Replace and torque
tighten drain plug to 12ft/lb or 16Nm. Unscrew and
remove cover (3) from tube (2) counter-clockwise when
viewed from above. It may be necessary to use a 1"
socket wrench on the hexagon on the cover (3) to
loosen the cover initially.
NOTE: The UR310 series assembly is equipped with Pall's
'Auto-Pull' element extraction mechanism to facilitate element
removal. While removing the cap, tabs on the element endcap
lock into hooks in the cap and the element is automatically
pulled from the nipple.
7.3
For UR310H series (head service):
Open drain plug (7) at the bottom of the bowl assembly
(tube and cover) 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 assembly (2 and 3) from head (1) counter-clockwise
when viewed from below. It may be necessary to use a 1"
socket wrench on the hexagon on the cover (3) to loosen
the cover initially.
7.4
Element replacement (UE310 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.
