Element burst pressure:
UE310 element 10 bard (150 psid) differential minimum
Operating temperature range:
-29°C to 120°C (-20°F to 250°F) with fluorocarbon seals for
petroleum based and specified synthetic fluids
60°C (140°F) maximum in HWCF, water-oil emulsion or
water glycol
Bypass valve setting options:
4.5 ± 0.5 bard (65 ± 7 psid) cracking pressure
CAUTION:
Maximum surge flow should not exceed 1.3 times
normal flow.
Seals:
Fluorocarbon
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 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.
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.

UH310 Series
s e r v i c e i n s t r u c t i o n s
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 (UH310)
or with the filter tube and cover pointing downwards
(UH310H).
4.2
The minimum clearance required for element removal
is as follows:
4.2.1
UH310 series (cover service): 248mm (9.8in)
for length 8, 383mm (15.1in) for length 13,
553mm (21.8in) for length 20 and 1061mm
(41.8in) for length 40 housings.
4.2.2
UH310 series (head service): 143mm (5.8in)
for all lengths.
4.2.3
The UH310 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 UH310 head is supplied with a machined differential
pressure warning device ports, fitted 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 HA9000A104Z) and torque tightened to 40 lbft /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.
CAUTION:
Never operate the filter unless warning device port is
sealed.
4.4
Mount the filter assembly in position using four
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.
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.
