7.2. Cleaning/replacing: aluminium mesh filter and droplet separator
● Open the service door (see chapter 2.1).
● Detach the grounding cable of the mesh filter and the mist eliminator (see chapter 2.1) from the
housing wall. Therefore detach the protective grid, if necessary (see chapter 2.1).
● Pull the mesh filter and the mist eliminator out of the guide rail. The cleaning can be carried out
with a steam ejector.
If one of the filter elements is too heavily contaminated, it must be replaced
(see list of spare parts). We recommend having filter elements in stock.
● Push the mesh filter and the mist eliminator back into the guide rail.
On reinserting, the grounding cables must be installed again! The
earthing labels indicate where the grounding cables must be connected. Finally, the filter
elements must be checked for electrical grounding at the housing.
● Close the service door.
7.3. Cleaning the mud container
Release the water before cleaning the mud container. In order to reduce the consumption of additives
such as defoamer or especially antifreeze agents (when the wet cyclone separator is placed outside),
the water supply and water outlet should be connected in order to form a closed circuit.
WARNING
Explosion hazard.
The constitution of the shovel must not lead to the production of sparks or to damages at the
surface of the mud container.
During the cleaning operation, there must not be any effective sources of ignition in the
vicinity of the mud container. The maintenance personnel must ensure that static discharges
are avoided during work at the unit. It is also necessary to ensure that there is adequate
ventilation.
● Open the drain cock at the wastewater connection (see chapter 2.1).
● If the deposed mud agglutinates or clumps, the ball valve can choke from time to time.
Therefore it is advisable to control if the ball valve is free in using an appropriate object (e.g. a
stick) before you open the door.
● Open the cleaning flap (see chapter 2.1).
● Remove the remaining mud from the mud container with the help of a shovel.
● The interior of the container is cleaned with the help of an appropriate jet vapour. Please
respect the regulations according to the protection of the environment when cleaning the
container.
