Check that the pump has been working for the enough time. The final
vacuum level is directly related with the time of performance. The time
must be according to the volume to be evacuated.
Check that there is no leak in the connection or in the system to be
evacuated. Switch off the pump and check that the vacuum level re-
mains.
Check that all the connections and the equipment used are the appro-
priate ones.

Check that the pump sucks in air. If the pump sucks in air, it is possible
that the vacuum gauge is damaged. If the pump does not suck in air, it
is possible that the non-return solenoid valve is blocked.
