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 an 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 packaging to
be discarded.

General sources of information
3.1
For dimensions, operating parameters,
assembly/element part number, ordering information,
notes, performance data and specifications refer to
datasheet IMUH211EN.
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.

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
(UH211C) or with the filter tube and cover pointing
downwards (UH211H).
4.2
The minimum clearance required for element removal is
as follows:
4.2.1
UH211C series (cover service): 203 mm (8 in)
for length 8, 338 mm (13.3 in) for length 13,
and 508 mm (20 in) for length 20 housings.
4.2.2
UH211H series (head service): 100 mm (3.9 in)
for all lengths.
4.2.3
The UH211 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 30-33 ft/lb or 40-45 Nm. All visual
indicators must be clearly visible
NOTE: The UH211 head is supplied with two machined
differential pressure warning device ports, one fitted with a
bleed plug, the other 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 (HA9000A104Z) AND torque tightened to 40 ft/lb / 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.
4.4
Mount the filter assembly in position using two
7/16"-14 (‘A’ and ‘E’ ports) or M10 x 1.5 (‘C’ and ‘G’
ports) bolts in the holes on the head mounting pads.
Torque bolts to 9-19 ft/lb or 12-26 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.
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.
CAUTION:
Maximum surge flow should not exceed 1.3 times
normal flow.
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.
CAUTION:
Reverse flow through filter element will cause damage.
CAUTION:
Never operate the filter unless both warning device
ports are sealed.
