: Press with the unblocking tool on the hose coupling and pull the vacuum tubing out with pliers.
: Push the provided hose (4 in Fig. 2.7.4) into the compressed air distributor and connect it with
the C&P placement head.
: Replace the muffler into the compressed air distributor and bolt you on the cover.

2.8 Technical information for the re-fitting of the
vacuum pump operation.
A water ring vacuum pump can supply maximally four C&P6/12 heads. 2
A modified vacuum generator has been built into the
placement head in the C&P6/12. Thus the
pickup circuit through Venturi nozzles and the latch are carried out by the vacuum pump. 2

During normal operation the vacuum at the vacuum distribution block machine entrance should
not fall under -800 mbar. 2

Mutual influence of several mounting machines on a common pump: 2
Several mounting machines are tied to a vacuum pump; it is therefore advisable for the case of
mainte
nance, to build an additional stop valve into the vacuum inlet before each placement ma-
chine. 2
Only when the nozzles of all switched off mounting mach
ines are perpendicular is there no recip-
rocal effect under the mounting machines connected by the vacuum pump – even without (closed)
stop valv
es. 2
If the placement head is in the waiting position, the star
is between two star positions (half cycle).2
In this intermediate position the holding and pickup circuit are connected by the cross section. If
a placement machin
e is switched off in this parked position, it wastes the vacuum. – The vacuum
pump sucks in false air backwards over the muffler of the pickup circuit. This affects the compo-
nent heads of all attached mounting machines
, if no stop valves are inserted. 2
So that the Venturi pickup circuit maintains the vacuum, all mounting machines must run during
the e
ntire operation. 2
If the vacuum pump is switched off in this position, the
placement head sucks over the holding
circuit humidity and/or water from the vacuum pump. The water acts as a sealing medium for wa-
ter ring vacuum pumps. Therefore a check valve is insert
ed in the series pump with a noise reduc-
tion cover. Additionally an entrance air cleaner prevents a contamination of the vacuum pump.
Desp
ite these measure to prevent any damage to the property do not shut off the vacuum pump
whilst the placement machine is running. 2
