8. USE OF SYSTEM
Before using the system, make sure that it does not cause any danger to
persons or the environment.
8.1. Precautions
Before using the filter, make sure that the filter bowls are properly closed and all
connections tightly fastened.
8.2. General use of the filter
Do not exceed specified pressure limits.
Check the differential pressure over the filter at regular intervals.
In normal operation one chamber is filtrating and the other chamber is on idle.
It is also possible to use both chambers for filtrating. In this case the spool should be in the
middle position (the arrow head of the handle pointing downwards).
IMPORTANT NOTICE! Pressure measuring connections in the filter
housing above the spool ARE NOT WORKING in middle position. If the
middle position will be used, filter pressure drop indication have to be
carried out by the means of external indication devices.
