Installation and maintenance should be undertaken
by a competent person. National and local codes of
practice, Environmental regulations and Health &
safety Directives must be adhered to and take
precedence over any stated or implied practices
within this document.
For fluids having low conductivity, there exists the
possibility of the generation of static electricity
during use with all-polymeric components.
This could potentially lead to a static electricity
discharge resulting in the ignition of a potentially
explosive atmosphere where such an atmosphere
is present.
These Pall products are not suitable for use with
such low conductivity fluids in an environment
that includes flammable liquids or a potentially
explosive atmosphere.
Where flammable or reactive fluids are being
processed through a Pall capsule assembly, the
user should ensure that spillages during filling,
venting, depressurizing, draining and capsule
change operations are minimized, contained or
directed to a safe area. In particular, the user should
ensure that flammable fluids are not exposed to
surfaces at a temperature that may ignite the fluid,
and that reactive fluids cannot contact incompatible
materials that may lead to reactions generating
heat, flame or that are otherwise undesirable.
Pall capsule assemblies do not generate heat, but
during the processing of high temperature fluids,
including steam sterilization operations and process
upset conditions, it will take on the temperature of
the fluid being processed. The user should ensure
that this temperature is acceptable for the area in
which the filter is to be operated, or that suitable
protective measures are employed.
When processing flammable fluids, the user should
ensure that any air is fully purged from within the
assembly during filling and subsequent operation to
prevent the formation of a potentially flammable or
explosive vapour/air mixture inside the equipment.
This can be achieved through careful venting of
the assembly or system as detailed in the
user instructions.
To prevent damage or degradation which may
result in leakage of fluids from this equipment it is
imperative that the end user check the suitability of
all materials of construction (including seals on the
connections where appropriate) with the process
fluid and conditions. The user should ensure that
the assembly is regularly inspected for damage and
leaks, which should be promptly corrected, and that
seals (where appropriate) are renewed after every
capsule change.
Leakage of flammable or reactive fluids from this
assembly, arising through incorrect installation or
damage to the equipment (including any seals), may
generate a source of ignition if flammable fluids are
exposed to a heated surface, or if reactive fluids
contact incompatible materials that may lead to
reactions generating heat, flame or that are
otherwise undesirable. The user should ensure that
the assembly is regularly inspected for damage and
leaks, which should be promptly corrected, and that
any seals are renewed after every filter change.
The user should ensure that these products are
protected from foreseeable mechanical damage
that might cause such leakage, including impact
and abrasion.
Regular cleaning with an anti-static material is
required to avoid the build up of dust on the
filter assembly.
Should you have any queries – then please contact
your local PALL office or distributor.
