Notes on fi lter operation
◊ Do not perform any unapproved conversions and modifi cations on the fi lters.
Non-approved modifi cations will endanger the operational safety and may cause
damage or personal injury.
For ATEX-compliant fi lters:
— Filters for explosive gases as per ATEX must be earthed. Establish an
appropriate local equipotential bonding. Test and document the conduc-
tivity.
— For installation under explosion group IIC:
Make sure when attaching decals or other markings that the area they
cover does not exceed a total contiguous area of 20 cm2!
— Make sure when painting that the permissible coat thickness does not
exceed the limits stipulated for the area of application.
— The control of electronic accessories for ATEX-compliant fi lters must
be intrinsically safe.
◊ Avoid sudden pressure fl uctuations on pressure build-up and de-pressurization.
If the pressure builds up or drops, too quickly, this may cause damage to the
fi lter.
◊ When using accessories with an external power supply, there is a hazard from
electrical voltage. Heed the notes given in the operating instructions for the ac-
cessories. Work on electrical components only when they are deenergised.
Notes on maintenance
◊ Always maintain the prescribed service intervals. If these are not complied with,
the fi lter may not function correctly and the manufacturer does not accept any
liability whatever for any possible consequences.
◊ Repairs and maintenance should be carried out by specialist personnel only.
Use only suitable tools when working in an explosive environment.
Notes on disassembly and disposal
◊ Flush the entire system, including the fi lter, with inert gas before disassembling
fi lters used for fi ltering critical gases. Depressurise and disassemble the fi lter
only then.
◊ The fi lter housing and elements might be contaminated by substances held back
in the fi lter. Filters used for the fi ltering of critical gases might contain explosive,
fl ammable or poisonous substances. Therefore always read the material safety
data sheet of the respective gas. Dispose of all components of the fi lter accord-
ing to the applicable statutory regulations.
