Beforeuse,checkifthesealmaterialisresistantagainstthemedium,

theprocesspressureandtheprocesstemperature.

ClosealldrainconnectionsbeforethesetupofVEGAMAG81.Check

ifallconnectionsofVEGAMAG81aretight.

Amountedbypasspipemustalsowithstandanypressuretestthat
