The standard connection is ¼”, which can be
changed to ½” with the adapter provided.
The pressure pipe screw connection should be
made as gas-tight as possible.
The required switch-on and switch-off pressure
is achieved by turning the pressure adjustment
nut or the differential pressure adjustment
screw.
For this, the device must be installed ready for
operation and switched on by pulling the red
knob on the housing cover.
Fig. 1.1
The setting can only be changed in operation
and under pressure, by turning the pressure
adjustment nut in +/- direction. For switch-on
and switch-off pressure, see diagram.

Before making the electrical connection, the
locking screw on the housing cover must be
removed together with the hood.
The power supply connection is firmly screwed to

terminals (pump or compressor).
The protective conductor is attached to the metal studs
on the side.
Then push the protection against accidental contact
(VBG4) over the insulator.
Mount the hood in the correct position and fix with
the fixing screw on the housing cover.
