To check that the vacuum unit is
sealed, a vacuum cycle should be
run. If the cycle finishes in the spec-
ified time and with the preset pres-
sure (approx. 10 mbar), the vacuum
unit is sealed.
However, if the preset time is ex-
ceeded or the pressure not reached,
the vacuum unit has a leak, which
must be addressed.
