4.1 Installation
Installation in the vertical or horizontal position, or
sometimes upside down, preferably with vertical dia-
phragm.
If installed in a vertical position, the switching point p
S
will correspond to the scale value SK set on the hand
wheel. If installed in another position, the switch-
ing point p
S
will change and no longer correspond to
the scale value SK set on the hand wheel. Switching
point p
S
must be checked.

The housing must not be in contact with masonry. Mini-
mum clearance 25 mm (1").
Continuous operation at high temperatures (e.g. maxi-
mum ambient temperature) accelerates the ageing
of elastomer materials and reduces the service life
(please contact manufacturer). Ozone concentrations
exceeding 200 µg/m

or gases containing more than
0.1 %-by-vol. H

S accelerate the ageing of elastomer
materials and reduce the service life.
Vapours containing silicone can adversely affect the
functioning of electrical contacts. When using silicone
tubes, only use silicone tubes which have been suffi-
ciently cured.
Condensation must not be allowed to get into the
housing (if possible, install pipework with an ascending
gradient). Otherwise, there is a risk of icing of conden-
sation at subzero temperatures, the switching point
shifting or corrosion in the device which can lead to
malfunctions.
When installing outdoors, place the pressure switch
in a roofed area and protect from direct sunlight (even
IP 65 version).
In case of highly fluctuating pressures, install a restric-
tor orifice, see page 17 (Restrictor orifice).
