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.
7.2
Unscrew and remove filter bowl (2) from head assembly
(1), anti-clockwise when viewed from below. It maybe
necessary to use a 1" socket wrench on the hexagon to
loosen the bowl initially.
7.3
Drain fluid from the bowl into a suitable waste container.
7.4
Element replacement (UE209 Series): Remove filter
element (5) by turning clockwise (when viewed from
below) and gently pulling the element from the filter
head (1). 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.
7.5
DO NOT run the system without a filter element
installed. Check that the O-ring (3) between the head (1)
and bowl (2) is not damaged. Use the replacement filter
as indicated by the part number on the element endcap.
7.6
Lubricate element O-ring with clean system fluid.
Reinstall element in the filter head (1) by engaging
element and turning anti-clockwise until the element
tabs lock into the filter head. Lightly lubricate head-to
bowl O-ring with clean system fluid and reassemble the
until thread bottoms. Hand tighten only. O-ring sealing is
not improved by over tightening
7.7
Bleed the system and check for leaks as per
section 4.8.
7.8
After element change, ENSURE VISUAL INDICATOR IS
RESET BY PUSHING IN THE RED BUTTON. Electrical
differential pressure devices will reset automatically.
When system reaches normal operating temperature,
check that the 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.

Fluid sampling
Optimum sampling to verify fluid condition can be achieved by
the use of sampling adaptors installed on the hydraulic system
itself. For more information consult Pall or your local Pall
distributor. Pall offers a fluid contamination analysis service -
consult the Pall sales office.
