7.6.1. Feeding the precoat via a FVS (TEKA spark pre-separator)
This chapter is only relevant if the filter unit is equipped with a FVS (TEKA spark pre-separator).
A FVS is a water separator installed in the suction pipe of the filter unit.
When using a FVS it is important to have the precoat sucked in via the FVS.
If the precoat is sucked in via a capture point located in the airflow before the FVS,
the precoat would be bound in the water of the FVS. The precoat would then not reach the filter
cartridges.
● Open the door (A) of the FVS.
The door must be opened wide so that it does not slam due to the suction
when the filter unit is switched on.
● Switch on the filter unit.
● Add the precoat inside the FVS. As the point of entry (B), use the transition to the connecting
pipe leading to the filter unit
● Now switch off the filter unit - before closing the door of the FVS again.
Otherwise, when the filter unit is switched on, the door is suddenly sucked
in. Risk of injury.
● Close the door of the FVS.
