4.1. Checking u on recei t
• When the g ds are delivered, make sure that all parts listed n
the delivery n te are in perfect c nditi n and have suffered n damage
during shipping.
• Make sure the vacuum pump has its identificati n plate affixed n
the fr nt c ver. Pumps with ut such identificati n are t be c nsidered
an nym us and p tentially danger us: in such an event, they must n t
be used, therwise the manufacturer will be deemed free fr m any
liability whats ever.
4.2. Checking u on recei t
• When the g ds are delivered, make sure that all parts listed n
the delivery n te are in perfect c nditi n and have suffered n damage
during shipping.
• Rem ve the parts f the packaging that can be danger us if
sucked by the c mpress r.
• Make sure the c mpress r has its identificati n plate affixed n
the fr nt gearb x. Pumps with ut such identificati n are t be
c nsidered an nym us and p tentially danger us: in such an event,
they must n t be used, therwise the manufacturer will be deemed free
fr m any liability whats ever.
4.3. Mounting
• The m unted aspirat r must be accessible f r maintenance and
firmly fixed n a frame r angled base with a 3° max inclinati n n x
and y axes (see Fig. 4.1). The structure must be fit t av id flexi ns r
vibrati ns.
• Make sure that there is en ugh free r m ar und the pump f r a
c rrect air c ling circulati n and pr tect the pump fr m the exp sure
t dirt and debris.
• Prepare the necessary space f r an easy access t the lubricati n
check-p ints (tank level and gear b x, ilers) and t the il tank filling
p rt, the f ur-way manif ld handle, and the vane wear inspecti n p rts.
4.4. Vacuum - ressure line
• T av id accidental sucti n f liquids inside the pump, install a
primary (p s. 1) and a sec ndary fl w shut ffs (p s. 2). If necessary,
install als a sucti n filter (p s. 4) t pr tect fr m s lids infiltrati n.
• The exhaust silencer (p s. 6) is designed t reduce the n ise level
and t separate the il mist c ming ut fr m the pump utlet p rt. The
separat r must be peri dically drained fr m il and c ndensate
accumulated in the separat r during the n rmal pump functi ning.
• The diameter f the vacuum/pressure line pipes must be pr perly
dimensi ned t the pump fl w and, in any case, larger than the
diameter f the p rts.
• The pipes weight must n t s licit the b dy f the pump. Use high
temperature resistant rubber c nnecti ns.
• Bef re m unting the vacuum line t the pump, rem ve the p rt
pr tecti ns. Pipes and all line c mp nents must be clean.
• Av id restricti ns and tight curves as much as p ssible if n t
strictly necessary.
• Exhaust pipes can reach high temperatures. Hence, they must be
pr perly is lated.
