OPERATING
Condor pressureswitches were built according to the relative and approved regulations of the time period
when they were developed and produced and are considered to be safe during operation. However, this
device can present risks if it is used by personnel without specialist training, or is used inappropriately or in
an unapproved manner. The safety data sheet and the local legal regulations are to be strictly observed.
The pressure switches serve the surveillance
compressors in dependence on the prevailing pressure.
*1
•1: If air out of the tank is released through the release
valve after shutting Off the switch, the non-return valve
on the compressor is to be checked.
•2: The pressure values shown on the label are the
factory settings set by Condor. These can be adjusted.
See the pressure setting diagram.
