A high back pressure in exhaust channel 3/5 will impair
the functioning of the vacuum generator.
Make sure that there is optimal exhausting.

sub−bases (in channel 3/5) can influence the vacuum gen
eration.
In this case, separate exhaust channel 3/5 between the
·
vacuum generator plates and the valve sub−bases by
means of the separator plate with Ident. code S.
Connect the work lines to the vacuum generator plate:

·
Seal work connection 2 with a blind plug.
·
Vacuum valve sub−base with Ident. code E:
