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.
3.2 This equipment has been assessed in accordance with
the guidelines laid down in the European Pressure
Equipment Directive 2014/68/EU and has been classified
within sound engineering practice S.E.P. We hereby
declare the equipment meets the requirements of Article
4 paragraph 3 thus meeting the directive requirements.
Under the provisions of the 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.
4.2 The minimum clearance required for element removal is
as follows:
4.2.1 552mm or 21.7" for length 20 and 1060mm or
41.7" for length 40 assemblies.
4.2.2 The UR610/UR690 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 UR610/UR690 housing is supplied with two
machined differential pressure warning device ports, one fitted
with a blanking 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 (P/N HA9000-A104Z) 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 the mounting
bracket kit (12) (if provided). Brackets require four 0.375"
(10mm) bolts each.
4.4.1 UR610/UR690 - Four additional mounting holes
with 1/2"-13UNC threads (for A and D ports)
or M12x1.75-6H threads (for C and F ports)
are provided at the inlet port for mounting the
assembly, using the appropriate gasket, to the top
of a reservoir or manifold.
4.4.2 Torque bolts to: 16 lbft (22 Nm) minimum for
0.375" (10mm) size bolts and 20-25 lbft (27-34
Nm) for 1/2" - 13 UNC or M12x1.75-6H bolts.
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.
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.
CAUTION:
Never operate the filter unless both warning device
ports are sealed.
CAUTION:
Reverse flow through filter element will cause damage.
