Do not operate the MBC... below 0 °C in liquid gas systems. Only suit-
able for gaseous liquid gas, liquid hydrocarbons destroy the sealing
materials.
MBC... ont été conçus pour être utilisés avec des GPL à l‘état gazeux

Negli impianti a gas liquido, non si dovrà far funzionare il MBC... al di sotto
di 0 °C. Esso è adatto soltanto per gas liquido gassoso, gli idrocarburi
liquidi distruggono i materiali delle guarnizioni.
