The actual operating conditions should be checked by the user to ensure
that the element, housing and all seals are compatible with the fluid and
application, and are within local safety codes. Please contact Pall or
approved distributor if further information is required.
CAUTION:
Maximum surge flow should not exceed 1.3 times
normal flow.
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 IMUR329EN.
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.
4.2 The minimum clearance required for element removal is
as follows:
4.2.1 530 mm or 21" for length 20 and 1040 mm or 41"
for length 40 assemblies.
4.2.2 The UR329 filter 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 ft/lb or 54 Nm. All visual indicators must be
clearly visible.
NOTE: Each head in the UR329 housing is supplied with two machined ports,
one drain port and one differential pressure warning device port. The drain
port is fitted with a drain plug and the differential pressure port 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-P8-Kit Z). The indicator or blanking plug shall be torque
tightened to 40 ft/lb 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 both warning device ports
are sealed.
4.4 Mount the filter assembly using the four 14.3 mm (0.563")
diameter holes in the manifold assembly.
4.5 Use a check valve downstream of the filter if there is a possibility
of reverse flow.
CAUTION:
Reverse flow through filter element will cause damage.
4.6 Install the filter housing using additional piping/valving to allow
complete filter assembly bypass if filter maintenance is required
without system shutdown.
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 electrically isolated from the user's earthing system. This filter assembly
must be earthed by connecting the user's 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.
