element part number, ordering information, notes,
performance data, and specifications refer to datasheet.
3.2 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 for
UR229C version and downwards for UR229H version.
4.2 The minimum clearance required for element removal of
is as follows:
4.2.1 UR229C series (cover service): 429mm (16.9in)
4.3 Threaded differential pressure devices, when fitted, must
NOTE: Head has a machined port for a differential pressure
warning device. The port may be sealed with a port plug
kit. Never place the port plug kit in this port without first
installing uniform size -014 Oring 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 .50-13x.75 deep
threaded holes in the valve body assembly.
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 electrically
isolated from the users earthling system. This filter assembly
must be earthed by connecting the users earthing system to
one of the inlet/outlet connections.
CAUTION:
Reverse flow through filter element will cause damage.

Refer to section 5.2.
(i) On completion of commissioning, position change-over
valve to select on-line side of housing.
CAUTION:
Failure to bleed the filter housing adequately will
increase the dissolved air content of the system fluid
which will shorten fluid life and may cause other
problems in the system.
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.
6 Differential pressure devices (optional)
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 a 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 at normal operating temperature, replace
the 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.
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.
Electrical connections and ratings for all differential
pressure switch options:
110 VAC = 4A (inductive),
220 VAC = 4A (inductive),
28 VDC = 3A (inductive),
48 VDC = 1A (inductive),
125 VDC = 0.25A (inductive),
Maximum inrush - 24 amps.
Underwriter’s lab. Inc. listed ratings of pressure switch
(Microswitch) options are:
4 amps at 250 VAC
0.25 amp resistive at 220 VDC

7 Filter element 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. Do not service when a potentially explosive
atmosphere is present.
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 into bypass.
Refer to Pall Product Literature for item numbers for applicable
replacement element series. Remove and replace element as
follows:
