OR NH3P PURIFICATION MATERIALS.

Note: Purier models PG2400 and PG11000 containing these materials
have an aluminized label afxed to the housing which states “WARNING:
Possible Burn Hazard, For Use With Substantially Oxygen-Free Process
Gases Only!”
• Do not puncture the housing (or remove plug from ll port, models
PG2400 and PG11000). Modication of the purier assembly could
result in contact with chemicals that may cause severe burns to the
eyes and irritation of the skin (Reference Safety Data Sheets, SDS,
supplied with assembly).
• Hazardous gas should never be introduced into the purier or
associated piping until a eld leak test demonstrates the system is
ready for service (see step 12 of this installation procedure). Pall
Corporation assumes no liability for damage or injury resulting from
improper installation or operation of the Gaskleen®purier assembly.
The user is ultimately responsible for equipment integrity and to
comply with any applicable safety standards.

INSTALLATION PROCEDURE:
Figure 1: Flow Schematics
The schematics above show a suggested tubing arrangement
for a Pall Gaskleen®Bulk Gas Purier or Pall Gaskleen®Bulk Gas
Purier with bypass manifold. The PG550 and PG2400 models
come without shut-off valves. The PG11000 model comes
mounted on a panel with shut-off valves. Puriers with bypass
manifolds come with all the valves shown in the schematic.
Additional gas lines and valves are necessary if the purication
material requires conditioning before use (see Step 5 below).

Puriers are supplied with an over-temperature indicator, which
should be checked during installation. If the indicator turns
black, contact Pall Corporation SLS for technical assistance.
INSTALLATION AND SAFETY NOTES:
• Only trained personnel should install, operate, and maintain gas control
equipment.
• All compressed gases are potentially hazardous and must be handled
only by trained personnel. Incorrect execution of operations can cause
re, explosion, atmospheric release of hazardous gas, or costly
contamination of process equipment.
• Safety Data Sheets (SDS) for all gases and purication materials used
in the facility should be available for consultation by all concerned
personnel. These data sheets are obtainable from gas suppliers and
Pall Corporation.
• An upstream process gas pressure regulator and pressure relief device
must be installed when a potential exists for overpressurization (i.e.
pressure surge beyond MAWP of assembly).
• For in-line puriers (PG550 and PG2400 models) the inlet tting must
be installed nger-tight with inert gas purge ow introduced within
one minute after removal of the protective cap. Delay may result in
degradation of the purication material.
• For puriers that are a part of a bypass manifold systems and the
PG11000, do not at any time prior to purier installation attempt to
open manual valves or otherwise allow air to contact the purication
material bed. Valves must remain closed until installation is complete
and all equipment has been suitably leak tested and purged.
• Before starting a job, all personnel responsible for equipment installation
or operation must fully understand the specic procedures to be
accomplished and all pertinent safety considerations.

Table 3: Installation Information
1. SITE PREPARATION
• When working with components that contact process or purge gases
(for example, gasket-seal connection gaskets) always wear new, clean
latex gloves to prevent ngerprint contamination.
• Inspect all gasket-seal connector sealing surfaces for dirt, scratches,
dents, pitting, or corrosion before assembly. Clean or replace affected
connectors before assembly.
• Perform helium leak test on all affected process gas connections to
ensure system is leak free prior to installing purier. A spool piece with
appropriate end connections can be used in place of the purier for this
test. If the leak test is failed, locate and repair the leak and repeat the
test. Leak testing procedures are documented in SEMI F1, ASTM E
498, or ASTM E 499.
• Prior to installing purier, purge all tubing, ttings, and components in
the installation zone with inert gas (nitrogen or argon).

2. PURIFIER INSTALLATION
• Attach the purier in a vertical orientation to a suitable interior wall or
other architecturally stable element with suitable fasteners in accordance
with Uniform Building Code (UBC) requirements. See product datasheet
or drawings for bolting pattern. Most puriers are not intended for
exterior installation; however, bulk puriers are often installed outdoors.
Contact Pall Corporation SLS for technical assistance.
• User installation of bypass valve and piping is recommended to enable
direct purging of the process gas line. When the manifold option is
selected no additional piping is needed.
3. PROCESS GAS INLET AND OUTLET CONNECTIONS
• Do not remove purier or manifold inlet and outlet gasket-seal
connector terminators until immediately prior to equipment installation.
• When a purier is used for hazardous gas purication, it must be
installed within a suitable, exhausted enclosure. All connections external
to the enclosure must be welded and supported in accordance with
pertinent safety ordinances and regulations. Dual containment lines
may be mandated for certain hazardous gases.
• Retain the inlet and outlet gasket-seal connection terminators for future
use when disconnecting the purier.
• Damage to the sealing surface may result if the gasket seal connector
is over-tightened or installed without a gasket. New gaskets must be
installed for each connection made (supplied with the purier).
PG550, PG2400, and PG11000:
1. Start inert gas purge ow (Ref. Table 3, middle column) to the installation
zone by opening an upstream valve. MAINTAIN purge gas ow until
the installation of the assembly is complete.

2. If necessary, remove and dispose of existing component (or spool
piece) by disconnecting ttings upstream and downstream of the
component, removing the component and gaskets, and capping the
component end connections. Use safety precautions appropriate for
the type of process gas being puried.
3. Inspect sealing surface(s) of the gas line ttings. If damage exists,
replace the ttings.
4. Attach the supplied gas-specic sticker to the aluminized label on
purier assembly (if applicable).
5. With purge gas owing from the inlet line, remove the protective cap
from the inlet of the purier (or inlet valve for the PG11000) and
immediately install the inlet gas line on the unit using a new gasket
(supplied with the purier). Tighten the nuts until nger tight.
6. Gasket seating begins when there is sudden resistance to nut rotation.
Using an appropriate open-end wrench on the purier and on the
connection nut (Ref. Table 3, last column), tighten per connection make
up instructions provided by the gasket seal supplier.
Note: Gasket suppliers typically recommend that the connection nut be
rotated an additional 45 degrees (⅛turn) from the nger tight position
for nickel, silver-plated nickel, or stainless steel gaskets.
7. For PG11000, slowly open inlet valve. Allow purier to come to
equilibrium with upstream gas supply pressure by introducing purge
gas into the unit (Pall recommends setting the purge gas supply
pressure between 30 – 60 psig, 0.21 – 0.41 MPa). Do not exceed
MAWP for purier. Once equilibrated (this may take up to 10 minutes)
partially open outlet valve.

8. Remove the protective cap from the outlet end of the purier.
9. If purge gas ow is not detected from the outlet end of the unit, increase
gas pressure or ow rate until gas is detected (for the PG11000, opening
the outlet valve more may be necessary to initiate purge gas ow).
10. Connect the outlet end of the purier to the process gas delivery line
leading to the equipment using a new gasket (supplied with the purier).
Tighten the nuts until nger tight and tighten the tting as in Steps 5
and 6.
11. Open the isolation valve downstream of installation zone. Ensure the
gas ow path in the outlet gas line is open to vent or scrubber.
12. Continue the ow of inert gas for 5 – 10 minutes.
13. Unit is now ready for helium leak testing.
PG550-MAN, PG2400-MAN, PG11000, and PG11000-MAN:
1. Start inert gas purge ow (Ref. Table 3, middle column) to the installation
zone by opening an upstream valve. MAINTAIN purge gas ow until
the installation of assembly is complete.
2. If necessary, remove and dispose of existing component (or spool
piece) by disconnecting ttings upstream and downstream of the
component, removing the component and gaskets, and capping the
component end connections. Use appropriate safety precautions for
the type of process gas being puried.
3. Inspect sealing surface(s) of the gas line ttings. If damage exists,
replace the ttings.
4. Attach the supplied gas specic sticker to the aluminized label on
purier assembly (if applicable).

5. With purge gas owing from the inlet line, remove the protective caps
from the inlet and outlet valves on the purier manifold and immediately
install the inlet supply gas line on the unit using a new gasket (supplied
with the purier). Then, install the outlet of the unit to the process gas
delivery line leading to the equipment using a new gasket (supplied
with the purier). Tighten the nuts until nger tight.
6. Gasket seating begins when there is sudden resistance to nut rotation.
Using an appropriate open-end wrench on the purier and on the
connection nut (Ref. Table 3, last column), tighten per connection
make up instructions provided by the gasket seal supplier.
Note: Gasket suppliers typically recommend that the connection nut
be rotated an additional 45 degrees (⅛turn) from the nger tight
position for nickel, silver-plated nickel, or stainless steel gaskets.
7. Open the isolation valve downstream of installation zone. Ensure the
gas ow path in the outlet gas line is open to vent or scrubber.
8. Open bypass valve and ow gas through bypass line.
9. Close bypass valve, wait for 2 seconds, and then open bypass valve
again. Repeat this procedure at least 10 times. These alternate
pressurization and venting cycles will reduce impurities (atmospheric
air and moisture) at the purier inlet valve connection. This process
works best if there is a ow check valve downstream of the purier.
10. Close downstream isolation valve, then close bypass valve.
11. Open the manifold inlet valve then slowly open the purier inlet valve.
Allow purier to come to equilibrium with upstream gas supply pressure
by introducing purge gas into the unit (Pall recommends setting the
purge gas supply pressure between 30 – 60 psig, 0.21 – 0.41 MPa).
Do not exceed pressure rating, MAWP, for purier. Equilibration
process may take up to 10 minutes.

12. Once equilibrated, open the purier outlet valve, the manifold outlet
valve, and then the downstream isolation valve. This will initiate purge
gas ow through the unit. Ensure the gas ow path in the outlet gas
line is open to vent or scrubber.
13. If purge gas ow is not detected from the outlet end of the unit,
increase gas pressure or ow rate until gas is detected.
14. Continue the ow of inert gas for 5 – 10 minutes.
15. Unit is now ready for helium leak testing.
4. HELIUM LEAK TESTING
Shut off system isolation valve downstream of the purier (part of the
process gas delivery line leading to the equipment), and then shut off
purge gas source (via upstream isolation valve).
Testing in-line purifiers (PG550 and PG2400):
1. Supply puried helium gas to the installation zone.
2. Open upstream isolation valve at purier.
3. Pressurize purier with helium up to maximum rated pressure (MAWP)
of unit.
4. Perform an outboard helium leak test on the purier at the inlet and
outlet gasket seal connections using a sniffer probe.
5. Should leakage be detected, contact Pall Corporation SLS for technical
assistance. Do not attempt to repair purier or valves in assembly.
6. Close upstream isolation valve at purier.
Testing manifolded purifiers (PG550-MAN, PG2400-MAN, PG11000,
and PG11000-MAN):
1. Shut off upstream and downstream isolation valves on the purier
manifold.

2. Supply puried helium gas to the installation zone.
3. Open by-pass valve (red handled) and pressurize manifold header with
helium up to the maximum rated pressure (MAWP) of the unit.
4. Perform an outboard helium leak test on the valves and the inlet and
outlet gasket seal connections using a sniffer probe.
5. Should leakage be detected, contact Pall Corporation SLS for technical
assistance. Do not attempt to repair purier or valves in assembly.
6. Close by-pass valve and then open upstream and downstream isolation
valves on the purier. Note: manifolded puriers require opening of four
valves (blue handled).
7. Pressurize purier and the remainder of the manifold with helium up to
maximum rated pressure (MAWP) of unit.
8. Perform an outboard helium leak test on the purier, valves, and
gasket seal connections using a sniffer probe.
9. Should leakage be detected, contact Pall Corporation SLS for technical
assistance. Do not attempt to repair purier or valves in assembly.
10. Close upstream and downstream isolation valves on the purier
manifold.
CAUTION: Inboard helium leak testing of the purier is not recommended
because of the possibility of contaminating the AresKleen purication
material by air inltration when returning from vacuum. Also, as shipped,
Pall Gaskleen®Bulk Gas Puriers contain trace amounts of helium due to
standard manufacturing processes. A spool-piece can be used to perform
an inboard helium leak test on the process lines prior to installation of the
purier. If inboard helium leak testing of the purier is required contact
Pall Corporation SLS for technical assistance.

Following helium leak test:
1. Shut off puried helium supply and resume purge gas source (ensure
that the purier remains pressurized).
2. Depressurize the purier of helium by opening downstream isolation
valve(s) on the purier and then system isolation valve downstream of
the purier.
3. Before the purier reaches atmospheric pressure, open upstream
isolation valve(s) on the purier.
4. Post-purge the purier assembly and gas line by owing inert gas at
the installation purge ow rate (ref. Table 3, middle column) for 5 – 10
minutes to displace remaining helium.
After completion of the above procedure, the purier is ready for conditioning.
5. CONDITIONING
The purpose of the conditioning procedures is to displace inert
gas used during installation of the purier and either generate or
activate certain functional groups that are chemically bonded to
the AresKleen purication material. Any stray contaminants
introduced during the installation procedure are also removed
during the conditioning process.
WARNING:
Conditioning of purication material with reactive or corrosive gases is
usually an exothermic (heat-producing) reaction. When conditioning is
improperly executed, personal injury from re or hazardous gas
emissions can result. To preclude atmospheric pollution and to avoid
contamination of process lines and process tool, efuent gases exiting
the purier during conditioning should be directed to a suitable scrubber.
Should questions arise during conditioning, immediately interrupt
process gas ow by closing the inlet and outlet valves on the purier,
then contact Pall Corporation SLS for technical assistance.

• When the purication material is initially exposed to some process
gases, substantial amount of process gas may react or be adsorbed
on the purication material, resulting in initially unstable purier perform-
ance. For best results, such purication material must be conditioned
with intended process gas before start up.
• The specic conditioning procedure required depends upon the nature
of the process gas and the type of purication material used. Carefully
follow the procedure that is provided. In particular, do not exceed the
recommended process gas ow rate as overheating and damage to
the purication material could result.
• Conditioning should be done after purier installation. Conditioning is
also recommended if a purier has been out of service for two weeks
or longer (especially for Intended Process Gases within Group IV). When
the process gas consists of a blend of two or more gases, conditioning
is recommended if the purier has been out of service for three days or
longer. Conditioning ensures that the relative percentage of the
constituents remains unchanged upon passage through the purier.
• Once the purication material is conditioned with the process gas, it
should be kept under positive pressure of that process gas at all times.
Should purging with an inert gas ever be required, the purication
material will require conditioning again before returning to service.
Consult with Pall Corporation SLS for technical assistance and
recommendations.
• DO NOT subject previously conditioned purication material to a vacuum.
Any hazardous gas physically adsorbed on the purication material
surface may be released when the material is subjected to a vacuum.
Contact Pall Corporation SLS for technical assistance with sub-
atmospheric operation of purier.

• Purication material on-site conditioning typically requires a process
gas ow control and monitoring device, such as a delivery line throttling
valve and a ow meter. Such components are not provided as standard
equipment. The purchaser is solely responsible for obtaining and
installing these components.
For conditioning, a minimum volume, V (liters), of the process gas is
required. If a pure process gas (100% concentration) is used at a ow rate
of F (slpm), the minimum time for gas ow, T minutes, during conditioning
is given by:
T minutes = V/F
If a carrier gas is being used to dilute the process gas, then a longer
conditioning time is required; the time increases proportional to the inverse
of the dilution percentage (A% – percentage of active ingredient). For
example, if the gas is actually a blend containing A% of the process gas,
then the minimum time, T minutes, is given by:
T minutes = V/((A%/100) F)
Select the appropriate gas group by active ingredient (see following pages).
Generally, the active ingredient is the Intended Process Gas as specied
in the Part number of the purier. Contact Pall Corporation SLS for
technical assistance.

Table 4: Conditioning
Note: Contact Pall Corporation SLS for technical assistance with
conditioning of any Gaskleen®Purier for service in gases not listed
below.
WARNING:
A purier that has been conditioned for a particular process gas must
be used for that process gas only. The AresKleen purication material
is gas specic. Without prior authorization from Pall Corporation,
Gaskleen®Bulk Gas Purier assemblies purchased for one gas must
not be used for any other gas.

With the exception of puriers containing AresKleen HCLP, HBRP or CDAP
material, all puriers are supplied with an over-temperature indicator afxed
to the housing. This indicator should be monitored during conditioning. If the
indicator turns black discontinue conditioning by stopping ow of condition-
ing gas and initiating ow of inert gas, then contact Pall Corporation SLS for
technical assistance. For puriers containing HCLP, HBRP or CDAP material,
the indicator is shipped in the purier’s original packaging but it is not afxed
to the housing. During normal conditioning for service in HCl, HBr or CDA
the temperature of the purier may increase enough to cause the indicator
to turn black. Therefore, Pall recommends that the indicator be afxed to the
purier after completion of the conditioning process.
Note: Before conditioning, verify that system is leak free and check that
the contents of the gas cylinder / gas source match the intended process
gas for use in the purier (as per the product part #). If the no leaks are
found and the cylinder contents are correct, then proceed with
conditioning process.

blends of these constituent gases.
Refer to Table 4, columns A and D, for the minimum volume of process gas
to ow through purier and the maximum ow rate not to be exceeded
during conditioning. As an example, condition a Gaskleen®PG2400 Purier
for H2service by owing 5.0 slpm (10.6 scfh) of 100% process gas through
the unit for 100 minutes.
