1. Initial Tests
1.1 Remove the Filter unit from the package in which it was shipped. Examine
closely the packaging for signs of abuse during shipment. Make sure that the
end dust plugs are attached to the unit. If the packaging appears to be abused, or
if the end plugs are not installed, arrange for return following the procedure set
forth in the “SERVICE” Section.
1.2 For Filter units having VCR connections, examine the sealing surface for signs
of abuse. If the sealing surfaces are scratched or otherwise damaged, arrange
for return following the procedure set forth in the “SERVICE” Section.
1.3 Examine the packing slip for the unit(s) ordered. Make certain that the unit(s)
shipped matches the unit ordered as verified by the packing slip.
2. After Installation and Operation
2.1 Filters are considered expendable parts. Over periods of use, to be determined
by the user, it will become necessary to exchange the filter for a new one.
Note: If the pressure drop across the filter exceeds a delta of 50% from the
original value, it may be an indication that the filter needs to be replaced.
2.2 Filters should be leak tested periodically, on a schedule provided by the user
based on experience, for degradation of the seals used in installation by using
one of the methods describe in the “INSTALLATION” Section..
2.3 Filters should be visibly inspected periodically, on a schedule provided by the

V. SAFETY PRECAUTIONS
1. Many Specialty Gases are hazardous in nature. It is important that the user of the
equipment carefully review the hazards associated with the gas to be used with the
Filter unit. Before installing the Filter unit into any system, refer tothe MSDS
that was shipped with the gas or on file in your facility, as to the specific
hazards associated with the gas to be used in the system. Also, refer to all
applicable inserts contained with the equipment for additional precautions
and operating instructions.
2. Before using any Filter unit on toxic, corrosive, pyrophoric, flammable or other
type of hazardous gas, test the leak integrity of the filter using an inert gas.
3. Make certain that the filter purchased is suitable for the application intended. All
Filter units supplied by Matheson, a model number, and a pressure limitation label
and/or stamping. Carefully review this information to establish the filter fit for
service in the desired application.
4. Make certain that the equipment purchased or delivered to the ultimate end user
conforms to the specifications of the user. The user is responsible for selecting
equipment compatible with gases that are to be used, physical parameters of
operation and performance and normal material compatibilities. Selection
information can be found in Matheson Catalogs, Matheson Tech Briefs and in the
Matheson Gas Data Book. In addition, any Matheson representative would be
pleased to aid in the selection of specific equipment.
5. Before installation of the Filter unit into a system, note the direction of the flow
arrow. Make certain that the arrow is in the same direction as the intended flow.
6. For Filter units supplied with NPT connections, use an approved method of pipe
sealing (such as an approved Teflon tape material) on the connection threads and
tighten no more than one and one-half turn past hand tight.
CAUTION: Do not over tighten. Over tightening may crack the fitting
housing and/or the Filter unit
7. For Filter units supplied with compression tube connections, face and deburr the
tubing to which the unit is to be attached. Following the manufacturer of the fittings
recommendations for tightening the compression tube fitting make the connection.
Most manufacturers of compression tube fittings recommend tightening the
locking nut one quarter turn past hand tight.
CAUTION: Do not over tighten. Over tightening may obstruct the flow of
gas through the tubing or the Filter unit.

6
8. For Filter units supplied with VCR type connections, make certain that the
connection in the system will mate to the connections supplied on the Filter unit,
before attempting installation.
CAUTION: Most VCR type connections require the use of an expendable
gasket. This gasket is to be used once. Make sure that the
material of the gasket used is compatible with the gases to be
used.
VI. GENERAL DESCRIPTION
Matheson Filters are designed for specific services. Make certain that the Filter ordered is
compatible with the application and the gases and/or liquids to be filtered.
Filters function as physical barriers to particulates. The filters marketed by Matheson use
two main methods to accomplish this goal. These methods as well as the series numbers to
which they pertain are listed below.
1. DEPTH FILTERS (Model 6124, 6134, 6164, and 6187)
2. MEMBRANE FILTERS (Model 6190)
Depth Filters generally consist of a fibrous wound material. Some may have a binder to
reduce the amount of fibrous shedding occurring during use. Over time, the relative lower
“depths” of the filter become increasingly more efficient as the particulate material is
trapped. Generally these filters are rated for 0.2 micron particle retention.
Membrane Filters employ a flexible and porous membrane as the physical barrier. The
membrane is either a flat single sheet or a pleated structure encasedin a housing. The pore
size of the unit is determined by physical measurement of the pores. The rating of the
filter also takes into consideration the weak physical forces of attraction associated with
this method of filtration. Generally these filters are rated for 0.01 micron particle
retention.
NOTE: Filters are not purifiers. Filters remove only particulate matter from gases
or liquids and do not remove chemical contaminants.

7
VII. INSTALLATION
For maximum performance and service life, the filter should be installed in a clean,
dry atmosphere, relatively free of shock and vibration. Sufficient room for access to
plumbing should be provided to facilitate maintenance. Fitting dust caps should be
removed just prior to installation
1. Gas Connections
1.1 Ensure that the flow in the system in which the Filter unit(s) is/are to be installed
is in the direction of the arrow indicated on the body of the Filter unit(s).
1.2 Matheson supplies the Filter unit(s) with a variety of end connections. Use an
approved method of sealing on the connection.
CAUTION: Do not over tighten. Over tightening may cause damage to the
Filter unit(s).
1.2.1 For Filter units supplied with NPT connections, use an approved method
of pipe sealing (such as an approved Teflon tape material) on the
connection threads and tighten no more than one and one-half turns past
hand tight.
CAUTION: Do not over tighten. Over tightening may crack the fitting
housing and/or the Filter unit(s).
1.2.2 For Filter units supplied with compression tube connections, face and
deburr the tubing to which the unit is to be attached. Following the
manufacturer of the fittings recommendations for tightening the
compression tube fitting make the connection. Most manufacturer
compression tube fittings recommend tightening the locking nut one
quarter turn past hand tight.
CAUTION: Do not over tighten. Over tightening may obstruct the flow of
gas through the tubing or the Filter unit(s).
1.2.3 For Filter units supplied with VCR type connections, make certain that
the connection in the system will mate to the connections supplied on the
Filter unit, before attempting installation.
CAUTION: Most VCR type connections require the use of an expendable
gasket. This gasket is to be used once. Make sure that the
material of the gasket used is compatible with the gases to be
used.

8
1.3 Use only pre-cleaned tubing or pipe and clean, dry (< 1.0 ppm H2O) gases.
1.4 After Filter unit installation prior to the use of the unit, the plumbing system
should be thoroughly leak tested using either an approved soap solution or by
pressurizing the entire system with Helium and using an approved leak detector
and monitor for a leak rate of less than 1 x 10-5 cc/sec He.
NOTE: This step is required by the user when the Filter unit is to be used
in any hazardous material applications, such as but not limited to,
flammable, toxic, corrosive, or pyrophoric applications.
2. Environmental Requirements
Refer to the “SPECIFICATIONS” section for the applicable Series of Filter.
3. Mounting
3.1 The filter units should be supported by some method compatible with the
application and location of the unit in a gas or liquid line.
3.2 The Filter unit should NOT be supported by only the tube or pipe to which it is
attached. This may cause radial or other stress to the connections securing the
unit in the gas or liquid line.
3.3 The Filter unit will function regardless of the physical position of mounting (eg.
horizontal, vertical or anywhere in between).

VIII. OPERATING INSTRUCTIONS
Read the "SAFETY PRECAUTIONS" and "INSTALLATION" sections before
operation of the equipment.
1. After installation in the system and prior to operation, the system should be
thoroughly leak checked (as described in Section VII, 1.4).
2. Begin to apply pressure to the system in acontrolled manner using a regulator or other
approved device for pressure regulation.
3. Within the system note the pressure before the filter in the line and after the filter in
the line. Record this information in a secure place.
NOTE: All Filters experience some pressure drop across the point where they are
installed. This is not uncommon and should be expected.
4. If there is sufficient flow and pressure across the filter, the system is now ready for
operation.
IX. MAINTENANCE
1. Filters are expendable parts. No maintenance is required until the Filter unit exceeds
the parameters listed in the TROUBLE SHOOTING Section. If the parameters are
exceeded, it is time to replace the unit.
2. Filters that are secured in a line with VCR type fittings require additional attention. If
the VCR seals are broken after original installation, the gasket employed is expendable
and must be replaced to ensure leak tight operation.
3. The maintenance period should be established by the user based upon historical
experience in the user's particular application.
