3. Installation
Pre-installation work
•
Make sure that the planned installation location is suitable for the operation of the GEA
explosion protected bag filter. This comprises the following:
– The classification of the installation site as a hazard zone according to RL 1999/92/EG
– Availability of a company internal document on explosion risk protection in accordance
with RL1999/92/EG and the occupational safety codes and regulations.
•
Remove the GEA explosion protected bag filter Multisack G85 EX from its packaging outside
the explosion risk zone:
– Handle the bag filter with care and do not damage the filter medium
– Inspect the bag filter for any external damage and check if the grounding set is complete
(operation manual and explosion protection label); if the filter is damaged or the grounding
set is missing - the filter may not be mounted.
Installation
•
Loosen the old grounding set from the unit.
•
Remove the old bag filter including the grounding set.
•
Carry out all necessary cleaning of the unit.
•
Insert the new GEA explosion protected bag filter Multisack G85 EX in the unit and secure
the filter using filter retainers.
•
Screw the grounding electric cable with a ring tongue lug to grounded unit component
together (e.g. filter retainer, slide in frame, monoblock etc.) in such a way that self or
accidental removal without a tool is impossible.
9
An electrically conducting connection between air filter frame and unit component must be
ensured!
•
Check the ring tongue lug for secure seat.
•
Check electric resistance between filter frame and unit component using an ohmmeter – no
matter where the measuring point is - electric resistance may not exceed 1 M
Ω
(
Mega-Ohm).
4. Operating Life/Durability of the GEA Explosion Protected Bag Filter Multisack G85 EX
The characteristics and features of the GEA explosion protected bag filter Multisack G85 EX are
the same as with conventional bag filters of the same type and same configuration.
•
Replace the bag filter when the maximum allowed end pressure difference is reached. It can
be assumed that the maximum allowed end pressure difference amounts to a standard value
with initial pressure difference plus 100 Pascal of pressure drop increase. Refer to section
"1. Technical Data" for the effective maximum allowed end pressure difference.
•
Moreover, consider the recommendations of the hygiene directive SWKI 2003-5 and VDI
6022 in terms of the maximum service life.
