Caution!
Handle the unprotected membrane with the
utmost care: it can be easily damaged.
– Do not remove the packaging and protective cap until
shortly before installation, so that the membrane
remains undamaged. Retain the protective cap.
– After disassembly, place the protective cap back over
the membranes immediately.
– Do not use force when installing the sensor, so as not
to cause damage to the device or the system.
