Filter installation
The filters are supplied in a ready to operate condition and can be installed
directly into the pipe system. To prevent transport damage, any ordered options
come separately packed. These accessories must be fitted to the filter before
commissioning and in accordance with the respective instructions supplied.
Also heed the information provided in the ancillary documents coming with the
accessories when installing ATEX-compliant accessories!
The control of electronic accessories for ATEX-compliant filters must be
intrinsically safe.
Requirements and preparatory activities
As a rule, the filters should always be used in the pipe system at the point
with the lowest temperature.
Ensure that the pipeline system is free of any contamination and clean it
before installing the filter, if necessary.
To ensure larger particles are safely trapped, a suitable strainer filter must be
installed upstream of any C, CF or CSF filter element.
A safety device for maintaining the maximum working pressure and the
permissible gas temperature must be available. This safety device must
prevent that limit values are exceeded.
A suitable pressure relief device and a condensate drain must be installed for
the filter. This safety device must prevent critical gas from escaping into the
atmosphere.
Danger due to release of a critical gas!
The release of a critical (explosive, flammable, poisonous) gas from the
network can constitute a considerable risk for man and environment.
Therefore heed the following before working on filters for critical gases
— flush the pipe section in question with inert gas
— have the notes on hazardous substances for the used gas ready
— take appropriate protection measures
— verify the absence of an explosive atmosphere
Installation
►
Before installing the filter:
—
flush the pipe section in question with inert gas if necessary
—
and depressurise the system.
►
Check filter for possible transport damage. Do not fit a damaged filter.
►
If necessary, fit a bracket or pipe support. Construct the support device such
that it can bear the weight of a filter completely filled with liquid.
►
Heed the flow direction when installing the filter in the pipeline! The gas must
flow through the filter in the direction of the arrow on the upper housing only.
