2 Receipt of equipment
The filter housing, and any optional equipment, are packed
individually for assembly by the customer. Unpack carefully
and ensure optional items are not mislaid in packaging to be
discarded.
3 General sources of information
3.1 For dimensions, operating parameters, assembly/
element part number, ordering information, notes,
performance data and specifications refer to datasheet.
3.2 This equipment has been assessed in accordance with
the guidelines laid down in the European Pressure
Directive 97/23/EC and has been classified within sound
engineering practice S.E.P. We hereby declare the
equipment meets the requirements of article 3, section
3, thus meeting the directive requirements. Under the
provisions of this directive the filter assembly is suitable
for use with group 2 fluids only.
3.3 Where under reasonably foreseeable conditions,
including external fires, the allowable limits could be
exceeded, suitable protective devices must be installed
by the customer within the connecting fluid system.
4 Installation of housing
4.1 The filter can be installed in any attitude, but for ease of
servicing, it is recommended that it be installed vertically
with the filter tube and cover pointing upwards (UR310) or
with the filter tube and cover pointing downwards (UR310H).
4.2 The minimum clearance required for element removal is
as follows:
4.2.1 UR310 series (cover service): 248mm (9.8") for
length 8, 383mm (15.1") for length 13, 553mm
(21.8") for length 20 and 1061mm (41.8") for
length 40 housings.
4.2.2 UR310H series (head service): 140.97mm (5.55")
for all lengths.
4.2.3 The UR310 Housing is supplied without a filter
element. For element installation and servicing
procedures, refer to Section 7.
4.3 Threaded differential pressure devices, when fitted,
must be torque tightened to 40 lbft or 54 Nm. All visual
indicators must be clearly visible.
NOTE: The UR310 head is supplied with a machined differential
pressure warning device port, fitted with a plastic shipping plug.
If no differential pressure warning device is ordered, the shipping
plug must be removed and replaced with a ‘B’ type blanking plug
(P/N HA9000-A104Z) and torque tightened to 40 lbft or 54 Nm.
NOTE: Never place the port plug in this port without first
installing uniform size -014 O-ring in lower O-ring groove,
otherwise a small bypass flow will result, allowing contaminant
downstream of the filter element.
CAUTION:
Never operate the filter unless a warning device port
is sealed.
4.4 Mount the filter assembly in position using 1/2" - 20UNF
- 2B (A or D ports) or M12 x 1.75 - 6H (C or F ports)
bolts in the holes on the head mounting pads. Torque
bolts to 20 - 25 lbft or 27 - 34 Nm.
4.5 Use a check valve downstream of the filter if there is a
possibility of reverse flow.
4.6 Install the filter housing using additional piping/valving to
allow complete filter assembly bypass if filter maintenance
is required without system shutdown. This series is not
available in a duplex or service bypass configuration.
CAUTION:
Reverse flow through filter element will cause damage.
NOTE: Piping supports should be provided as close as is
practicable to the port connections in order to minimize
external loads. This filter assembly must not be electronically
isolated from the users earthing system. This filter assembly
must be earthed by connecting the users earthing system to
one of the inlet/outlet connections.
4.7 Connect lines or hoses to housing inlet and outlet ports.
WARNING:
USE FITTINGS OR ADAPTORS COMPATIBLE WITH
PORTS SUPPLIED AS SHOWN BY PART NUMBER
ON NAMEPLATE AND NOTED IN DATA SHEETS:
USE OF INCORRECT FITTINGS OR ADAPTORS CAN
CAUSE FILTER HOUSING OR MANIFOLD FAILURE
RESULTING IN LOSS OF PRESSURE AND POSSIBLE
SYSTEM FAILURE OR PERSONAL INJURY.

NOTE: Painting of the filter housing is optional. The coating
on the filter housing is a suitable painting base. Cover the
differential pressure warning device and nameplate if painting
of the housing takes place.
4.8 Bleed the filter
4.8.1 UR310 (cover service): Bleed the filter by opening the
vent plug (7) at the top of filter one and one-half turns.
Jog system and fill filter until all air bleeds through the
plug, then torque tighten plug to 12 ft/lb or 16 Nm.
4.8.2 UR310H (head service): Bleed the filter by opening the
vent plug (7b) on the head one and one-half turns. Jog
system and fill filter until all air bleeds through the plug,
then torque tighten plug to 12 ft/lb or 16 Nm.
Pressurize system fully and check for leaks; if leaks occur
refer to section 5.
CAUTION:
Failure to bleed the filter housing adequately will
increase the dissolved air content of the system fluid
which will shorten fluid life and may cause other
problems in the system.
5 Routine maintenance
5.1 Pall filters do not normally require special attention
except for periodic monitoring of the differential pressure
warning device. Schedule replacement of filter element
every six months or sooner, and have ample supply of
spare elements available.
5.2 If external leakage is noted, replace O-ring at leak. If
leakage persists, check sealing surfaces for scratches or
cracks; replace any defective parts.
5.3 Differential pressure devices actuate when the element
needs changing or because of high fluid viscosity in
‘cold start’ conditions. If ‘cold start’ conditions exist, see
Section 6.2 and 6.3.
5.4 A dirty system can quickly plug a new filter element,
especially with Pall high efficiency filter media. It may
require one or two initial element changes to stabilize
element life. If element life is short or differential
pressure is excessive, filter may be undersized; refer to
the sizing and selection section of the product literature
or contact your local Pall representative.
5.5 Make sure element change labels are clean and
undamaged. Replace illegible labels with the appropriate
new labels.
6 Differential pressure devices
Reference should be made to product literature for dimensions,
operating parameters, part numbering, ordering information
and specifications.
6.1 Differential pressure devices actuate when the element
needs changing or because of high fluid viscosity in
‘cold start’ conditions.
6.2 If stainless steel visual indicator is fitted and actuates
during ‘cold start’ (red button extends 5mm, 3/16"), reset
by depressing the button when the normal operating
temperature is reached. If indicator actuates after
resetting, replace element. If brass visual indicator
is fitted and actuates during ‘cold start’ (flag inside
indicator changes to red), it will automatically reset when
normal operating temperature is reached. If indicator
is still actuated after normal operating temperature is
reached, replace element.
NOTE: Option ‘P’ visual indicator has thermal lockout and
manual reset. No signal below 0° C (32° F), signal above
29° C (80° F).
3
6.3 Use of both positive indication (green light) and negative
indication (red light for dirty element) is recommended to
effectively monitor filter element life.
6.4 If the electrical switch actuates (e.g. red light comes on)
during cold start, continue operating until the signal (red
light) goes out as system warms to normal operating
temperature. This feature can be used as ‘warm up’
indication in operating procedures. If the warning signal
(red light) remains or appears when system is warm,
replace the filter element.
Electrical connections and ratings are dependent on
indicator chosen. Typical values only are shown below:
110 VAC = 4A (inductive),
220 VAC = 4A (inductive),
28 VDC = 3A (inductive),
48 VDC = 1A (inductive),
125 VDC = 0.25A (inductive),
Maximum inrush - 24 amps.
Underwriter’s lab. Inc. listed ratings of pressure switch
When preset differential pressure is exceeded continuity
switches from Normally Closed (NC) - Common to Normally
Open (NO) - Common.
When differential pressure decreases below pre-set value,
continuity returns to Normally Open (NO) - Common to

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.
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.
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.
7.5 DO NOT run the system without a filter element installed.
For UR310 series: check that the O-ring (4) between the
cover (3) and tube (2) is not damaged.
For UR310H series: check that the O-ring (5) between
the tube (2) and head (1) 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 shell assembly. Lightly lubricate
cover-to-head or tube-to-head (as applicable) O-ring
with clean system fluid and reassemble the housing until
thread bottoms. Hand tighten only.
7.7 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.
7.8 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.
