Safety Instructions

Pressure switches are precision devices
which are calibrated in the factory. For this
reason, never open the device and do not
change the adjustment of the varnished
calibration screws.

Prevent excessive vibrations from reaching
the pressure switch, e.g., with mechanical
isolation or other vibration damping
measures.

Heavily contaminated media can clog the
sensor and cause errors and/or
malfunction. If the equipment is to be used
for this purpose, suitable chemical seals
must be connected.

Pressure switches and chemical seals form
a functional unit and must not be
disconnected from each other in the field.

Before disassembly (removing the
pressure switch from the system), the
device must be disconnected from the
power supply and the system must be
emptied. Observe the Accident Prevention
Regulations.

Never use the pressure switches as a
climbing aid.

Honeywell GmbH accepts no liability for
non-compliance.
