Please observe the following:
Test connection for pressure check:
To check the system pressure
(e.g. during inspection of the
machine), a test manometer
can be screwed onto the ¼”

24.2. Flow rate check
A flow rate check may become necessary during a machine in-
spection.
For checking, an adapter 1” must be build in between pump and
pressure hose. Flow rate checking unit must be adapted to this
1” adapter. (see also functional diagram)
After completion of the test, the fittings must be restored to their
original state, ensuring that there are no leaks.
