INSTALLATION AND REPLACEMENT INSTRUCTIONS:
Warning: It is the installer’s responsibility to comply with appropriate safety
procedures for working with gases under pressure and for toxic and other hazardous
gases. If installer is unsure of proper procedures, appropriate authority must be
consulted prior to beginning installation and/or removal of a filter.
Caution: GasShield GasketFilters are preconditioned with clean, dry nitrogen.

Extreme care should be taken to minimize the time which elapses between the
removal of the packaging and the installation of the filter to minimize contamination
of the filter.

Caution: Like any VCR compatible gasket, the GasShield GasketFilter is intended for
one-time use. Re-use of the GasketFilter could result in system leaks.
1.

Close valves upstream and downstream of the filter.

2.

Perform cycle purge to the gas system to get the component to be removed,
inerted and depressurized.

3.

Disassemble the connection and remove the used filter or gasket.

4.

Inspect all sealing surfaces and clean or replace as needed.

5.

In order to avoid contamination of the filter media, do not handle the
