How to service the filter
Interval
Replace the filter when the pressure loss exceeds recommended end pressure, see the
table.
The intervals are dependent on the concentration of dust in the air passing through the filter.
Use the following ways to determine if the filter needs to be replaced:
•
Use a filter monitor (if fitted) giving a signal with a lamp or another electrical device
when the filter is to be replaced
•
Use a pressure difference manometer which shows the filter pressure drop, see the
table
If no mechanical equipment is available to check the pressure loss, the filter should be
replaced when estimated necessary.
Before you start
No special tools are required for the service inspection.
Caution!
Remember to switch off the main power supply to the unit and its parts before starting
the service inspection!
