be discarded.
3 General sources of information
3.1 For dimensions, operating parameters,
assembly/element part number, ordering information,
notes, performance data and specifications refer to
datasheet IMUH319EN.
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 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
(UH319C) or with the filter tube and cover pointing
downwards (UH319H).
4.2 The minimum clearance required for element removal
is as follows:
4.2.1 UH319C series (cover service): 205mm (8.1in)
for length 8, 340mm (13.4in) for length 13,
510mm (20in) for length 20 and 1020mm
(40.2in) for length 40 housings.
4.2.2 UH319H series (head service): 138mm (5.5in)
for all lengths.
4.2.3 The UH319 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 38 ft/lb or 54 Nm. All visual
indicators must be clearly visible.
NOTE: The UH319 head is supplied with two machined
differential pressure warning device ports, one fitted with a
bleed 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 HA9000A104Z) 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 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.
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.
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.

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.
4.8 Bleed the filter
4.8.1 UH319C series (cover service): Bleed the filter by
opening the vent plug (7) at the top of filter one and one
half turns. Jog system and fill filter until all air bleeds
through the plug, then torque tighten the vent plug to
12 ft/lb or 16Nm.
4.8.2 UH319H series (head service): Bleed the filter by opening
the blanking plug (6b) one and one-half turns. Jog system
and fill filter until all air bleeds through the plug, then
torque tighten the blanking plug to 40 ft/lb or 54 Nm.
Pressurize system fully and check for leaks; if leaks occur
refer to section 5.
5 Routine maintenance
5.1 Pall filters do not normally require special attention
except for periodic monitoring of the differential pressure
warning device. Schedule replacement of filter element
every six months or sooner, and have ample supply of
spare elements available.
5.2 If external leakage is noted, replace O-ring at leak. If
leakage persists, check sealing surfaces for scratches or
cracks; replace any defective parts.
5.3 Differential pressure devices actuate when the element
needs changing or because of high fluid viscosity in
'cold start' conditions. If 'cold start' conditions exist, see
Section 6.2 and 6.3.
5.4 A dirty system can quickly plug a new filter element,
especially with Pall high efficiency filter media. It may
require one or two initial element changes to stabilize
element life. If element life is short or differential
pressure is excessive, filter may be undersized; refer to
the sizing and selection section of the product literature
or contact your local Pall representative.
5.5 Make sure element change labels are clean and
undamaged. Replace illegible labels with the appropriate
new labels.
6 Differential pressure devices
Reference should be made to product literature for dimensions,
operating parameters, part numbering, ordering information
and specifications.
6.1 Differential pressure devices actuate when the element
needs changing or because of high fluid viscosity in
'cold start' conditions.
6.2 If visual indicator is fitted and actuates during 'cold start'
(red button extends 5mm, 3/16"), reset by depressing the
button when the normal operating temperature is reached.
If indicator actuates after resetting, replace element.
NOTE: Option 'P' visual indicator has thermal lockout and manual
reset. No signal below 0°C (32°F), signal above 29°C (80°F).
6.3 If the electrical switch actuates (e.g. red light comes on)
during cold start, continue operating until the signal (red
light) goes out as system warms to normal operating
temperature. This feature can be used as 'warm up'
indication in operating procedures. If the warning signal
(red light) remains or appears when system is warm,
replace the filter element.
ENGLISH
6.4 Use of both positive indication (green light) and negative
indication (red light for dirty element) is recommended to
effectively monitor filter element life.

7 Filter element installation / servicing
During servicing, the external surfaces of the filter assembly
must be cleaned to remove any dust deposits.
Servicing must be conducted using suitable tools that do not
present a hazard.
Servicing must not be carried out when a potentially explosive
atmosphere is present.
Refer to Service Parts List (Section 9) for item numbers for
applicable replacement element series. Remove and replace
element as follows:
7.1 Turn off and depressurize the system.
7.1.1 For UH319C series (cover service):
Open vent plug (7) at top of filter one and one-half turns.
Open the blanking plug (6b) partially on the filter head
and drain fluid into waste receptacle.
This sequence may be long for high viscosity fluids.
Replace ad torque tighten drain plug to 12 ft/lb or 16Nm.
Unscrew and remove cover (3) from tube (2) counter-
clockwise when viewed from above. It will be necessary
to use a 1" socket wrench on the hexagon on the cover
(3) to loosen the cover initially.
Note: The UH319C series assembly is equipped with Pall’s
'Auto-Pull' element extraction mechanism to facilitate element
removal. While removing the cap, tabs on the element endcap
lock into hooks in the cap and the element is automatically
pulled from the nipple.
7.1.2 For UH319H series (head service):
Open the drain plug (7) at the bottom of the bowl
assembly (tube and cover) and drain fluid from the bowl
into a suitable waste receptacle. Replace and torque
tighten drain plug to 12 ft/lb or 16Nm. Unscrew and
remove the bowl assembly (2 and 3) from head (1)
counter-clockwise when viewed from below. It will be
necessary to use a 1" socket wrench on the hexagon on
the cover (3) to loosen the cover initially.
7.2 Element replacement (UE319 Series): Remove filter
element (8), if already fitted, and carefully inspect the
interior surface (flow through the element is in-to-out) for
visible contamination. Normally no dirt should show, but
visible dirt or particles can be an early warning of
system component failure. Discard both the filter
element and its O-ring. The filter element is NOT
CLEANABLE. Any attempt to clean the filter element can
cause degradation of the filter medium and allow
contaminated fluid to pass through the filter element.
WARNING:
DO NOT ATTEMPT TO CLEAN OR RE-USE THE
ELEMENT. ONLY USE GENUINE PALL
REPLACEMENT FILTER ELEMENTS.
CAUTION:
Filter elements should be replaced upon indication or
at specified intervals, six months maximum. Failure to
change the element will cause the filter to go on
bypass.
