Fema DCM Series Assembly And Operating Instructions Manual page 30

8. 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.
9. Prevent excessive vibrations from reaching the pressure switch, e.g. with mechanical
isolation or other vibration damping measures.
10. Heavily contaminated media can clog the sensor and cause errors and/or malfunction.
If the equipment is to be used for this purpose, suitable pressure mediators must be
connected.
11. Pressure switches and pressure mediators form a functional unit and must not be
disconnected from each other in the field.
12. 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.
13. Never use the pressure switches as a climbing aid.
14. Honeywell GmbH accepts no liability for non-compliance.
