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 IMUT279EN.
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 should be installed vertically with the cover
pointing upwards.
4.2
The minimum clearance required for element removal is
as follows:
4.2.1 111mm (4.4in) for length 4, 213mm (8.4in) for
length 8, 356mm (14.0in) for length 13 and
518mm (20.4in) for length 20 assemblies.
4.2.2 The UT279 Housing is supplied without a filter
element. For element installation and servicing
procedures, refer to Section 7.
4.3
Pressure gauge or electrical pressure switches, when
fitted, should be hand-tightened plus 1-2 turns with a
wrench. Connection is 1/8” NPT. PTFE sealant tape
should not be used on the threads.
NOTE: The UT279 housing is supplied with one machined
pressure gauge/switch port fitted with a blanking plug and an
air-breather as standard.
4.4
Mount the filter assembly in position using three bolts in
the holes on the head mounting pads. Torque bolts to
12 lb/ft (16.3 Nm). Refer to Figure 3 (Page 47).
4.5
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 electronically
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.
4.6
Connect lines or hoses to housing inlet ports.
Note: Painting of the filter housing is optional. The coating on
the filter housing is a suitable painting base. Cover the
pressure warning device and nameplate if painting of the
housing takes place.
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:
Do not operate the filter unless all warning device
ports are sealed.
