1.1 FILTER HOUSING
Construction
The lter housings are designed
in accordance with international
regulations. They consist of a lter
housing and a threaded cover plate.
Standard equipment:
with bypass valve in the element. For
RF 450/580 the bypass valve is built
into the cover plate as standard.

to the system must be switched off
before removing the clogging indicator
connector.
Filters must be exibly mounted and
not xed rigidly to the oor or used as
a pipe support.
