1.1 FILTER HOUSING
Construction
The filter housings are designed
in accordance with international
regulations. The two sections of the
filter housing with screw-on cover
plates are connected by means of a
ball change-over valve.
Standard equipment:
connections for venting and draining z
connection for a clogging indicator z
from size DN 80 the filters are fitted z
with a pressure equalisation line and
a ball shut-off valve
with bypass valve z

1.10 IMPORTANT INFORMATION
Filter housing must be earthed z
When using electrical clogging z
indicators, the electrical power supply
to the system must be switched off
before removing the clogging indicator
connector
Filters must be flexibly mounted and z
not fixed rigidly to the floor or used as
a pipe support.
When used with W/HC and P/HC- z
elements, please follow the sizing
recommendation under Point 3.3!
