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 Corporation or approved
distributor if further information is required.

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 the packaging that will 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 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 for
UR229C version and downwards for UR229H version.
4.2 The minimum clearance required for element removal of
is as follows:
4.2.1
UR229C series (cover service): 429mm (16.9in)
for length 08, 563mm (22.2in) for length 13,
734mm (28.9in) for length 20 and 1242mm
(48.9in) for length 40.
4.3 Threaded differential pressure devices, when fitted, must
be torque tightened to 40-43 ft/lb or 54-58 Nm. All visual
indicators must be clearly visible.
NOTE: Head has a machined port for a differential pressure
warning device. The port may be sealed with a port plug
kit. Never place the port plug kit in this port without first
installing uniform size -014 Oring in lower O-ring groove,
otherwise a small bypass flow will result,
allowing contaminant downstream of the filter element.
4.4 Mount the filter assembly using the four .50-13x.75 deep
threaded holes in the valve body assembly.
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 users earthling system. This filter assembly
must be earthed by connecting the users earthing system to
one of the inlet/outlet connections.
4.5 Lines or hoses can be connected to the following
housing inlet and outlet port options.
Port Type

F20
1.25 Dia. w/4xM10x1.5-6H
Mounting Holes
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 the housing.
4.6 Commission filter assembly as follows:
(a) Ensure that plugs are closed.
(b) Open left hand bleed plug one and one half turns.
(c) Position change-over valve to direct flow through left
hand housing.
CAUTION:
Maximum surge flow should not exceed 1.3 times
normal flow.
CAUTION:
Reverse flow through filter element will cause damage.
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.
