Safety notice for maintenance
For all devices
WARNING
This device is designed to operate with high pressure and / or hazardous media. For this reason, repair and maintenance
work performed on this device with connected supply lines can result in the leakage of hazardous substances from these
lines.
Therefore you must ensure that substances cannot leak prior to opening or dismantling the device, e.g. block the line or
separate the line from the device.
WARNING
If you are unable to eliminate faults, place the device out of service and protect it against inadvertent commissioning.
CAUTION
If the membrane of the pressure connection is cleaned with pointed or hard objects, you can destroy the membrane.
Therefore, do not use pointed or hard objects to clean the membrane.
NOTICE
Depending on the use of the device and certain empirical values, determine a maintenance interval for the tests to be
carried out repeatedly.
The maintenance interval is also influenced by the corrosion resistance depending on the site of use.
General explosion protection
WARNING
An explosion hazard exists when the device is repaired or serviced in explosive atmospheres.
Before opening the device, ensure that the surrounding atmosphere is not potentially explosive.
WARNING
So as to ensure the safety of the explosion protection, the device may be repaired only by repair shops authorized by the
manufacturer.
