Only connect test and calibration installations once the system has been
depressurised!
Never perform functional tests with compressed or medical air. This can
damage instruments with low pressure ranges.
The connection to the low-pressure controller is made via a 6.6 x 11 mm pressure connec-
tion. The hose diameter should be 6 mm.
