Use hoses of the recommended diameters.
A hose with insufficient internal diameter on the
74
74
62
pressure side will prevent the unit from receiving the
amount of compressed air necessary for optimum
performance.
A hose with insufficient internal diameter on the
vacuum side will cause excessive flow resistance
along the wall of the hose, with negative effects on the
Vacuum
suction capacity and thus on the evacuation times. On
6

the other hand, a hose whose internal diameter is too
large will have a large internal volume and will thus
6

also result in longer evacuation times.

Hoses should be kept as short as possible in order to
reduce the reaction times to a minimum.
Take care that the hoses are not kinked or pinched.

After all pneumatic connections have been made, the
compressed-air supply can be turned on.
