3 Mounting the supply pressure
regulator
Î To prevent excessive amounts of con-
densed water from collecting, keep the
distance between the compressor and
supply pressure regulator as short as
possible.
Î Make sure the drain plug faces down-
wards in versions with a lter receptacle.
3.1 Compact supply pressure
regulator
The supply pressure regulator can either be
mounted directly in the pipeline of the air
supply or on rails or brackets using the cor-
responding mounting parts (see accessories
in section8.2).
Observe the direction of ow of the supply
air. An arrow on the nameplate indicates the
direction.
