The actual operating conditions should be checked by the 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 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 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 IMUR610EN.

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.

4.2 

 The minimum clearance required for element removal of is  

as follows: 

 

4.2.1   443mm or 17.5” for length 20 and 951mm or 37.5” for 

length 40 assemblies.

 

4.2.2  The UR6xx Housings are 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: Each UR620 housing is supplied with two machined 

differential pressure warning device ports, one fitted with a bleed 

plug, the other with a plastic shipping plug. For UR640, UR660 

and UR680 duplexes, only the inner most housing has 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-P8-Kit Z) 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 using the four 14.3 mm diameter 

holes in the manifold assembly.

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.

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 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:

Reverse flow through filter element will cause damage.

CAUTION:

Never operate the filter unless both warning device 

ports

 

are sealed.
