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.
NEVER: 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 in position using the mounting
bracket kit (12) (if provided). Brackets require four .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.
CAUTION:
Reverse flow through filter element will cause damage.
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.
