2 Safety The VAC are used for quick attachment of vibrators to smooth or, within
limitation, convex surfaces. Among other applications, the VAC can be
used in combination with vibrators for emptying transport containers or
cleaning tubes and hoppers.
The VAC are used where there are otherwise no conventional mounting
options for vibrators, where frequent relocation is necessary and where
welding or screwing is not possible.
VAC can also be used outdoors as well as in dump environments. The
VAC may not be submerged in bulk materials or in liquids.
Any other use is considered improper.
Installation, commissioning, maintenance and troubleshooting of the VAC
may only be performed by authorised qualified personnel.
All handling of the VAC is the responsibility of the operator.
WARNING
Falling parts
The VAC can come loose with small component cross sections and in the
event of an unexpected pressure drop.
The vibrators screwed to the VAC can be loosened by vibration
Pneumatic vibrators at full power can cause the VAC to slide.
Falling parts can cause severe personal injuries.
➢All VAC except VAC 8 and VAC 10 are equipped with an adjustable
safety cable. Choose a secure attachment point (such as an eye) for
the safety cable on the container or system. Adjust the cable with the
cable clamps as short as possible so that the VAC can never fall into a
loose cable.
➢VAC 8 and VAC 10 have to be secured against dropping down by the
customer.
➢If you attach the VAC to round components, then the specified mini-
mum diameters given in Ch. Technical data (cf. page 8; "Parameters")
must be observed.
➢For the first start-up, set the frequency of the vibrator by means of a
throttle check valve (e.g. on the hose set HG ... with DRV) so that slid-
ing of the VAC is prevented.

WARNING
Compressed air
A loosened hose which is under pressure can lead to personal injuries.
➢Screw the hose lines on carefully.
➢Check the hose lines and connections after one hour of operation and
thereafter regularly (generally monthly).
➢Retighten the hose lines, if necessary.
➢Ensure that the compressed air is disconnected from the supply lines
during all work on the VAC.
➢Prevent the VAC from being switched back on during all work.
WARNING
Sound level
Depending on the VAC and vibrator used, the sound pres-
sure level may exceed 80 dB(A) in the vicinity of the con-
structions connected to the VAC. The human ear can be
permanently damaged by the high sound level.
➢When working in the noise area, use ear protection if
80 dB(A) is exceeded.
➢Depending on the design and combination of VAC and
vibrator, take additional noise protection measures.
WARNING
Risk of injury while handling heavy parts
Risk of serious injury due to weight during transport and installation of the
VAC.
➢Observe the weight information in Chapter Technical data, from page 8
on.
➢Only qualified personnel may transport and install the VAC.
➢Use suitable load handling devices and slinging equipment.
➢Wear suitable personal protective equipment.
NOTICE
Only use approved combinations of VAC and vibrator. The applicable vi-
brators can be found in Ch. Technical data, page 9.
When using other vibrators, the operator is responsible for checking safety
and functionality.

NOTICE
If VAC and vibrator are ordered separately, the vibrator must first be
mounted on the VAC, then the VAC on the container.
NOTICE
Operation of the VAC with silencers is mandatory.
Silencers reduce the noise level and protect the VAC from contamination
entering.
NOTICE
The VAC may only be operated on clean and dustless surfaces free from
grease.

the internal control bores is possible with drilling patterns other than the
templates (see Ch. Installation, from page 17 on). The above combinations
of VAC and vibrator are tested and can be used without restrictions except
those marked with */**.
When using other vibrators, the operator is responsible for checking safety
and functionality.
Depending on the vibrator used, the VAC ought to be used with the follow-
ing hose sets:

VAC mainly consist of a ground plate with suction cup(s) (1), a 2/2-way
ball valve (3) and a vacuum nozzle (4). By actuating the 2/2-way valve (3)
a vacuum is generated with the vacuum nozzle (4). As a result, the VAC
attaches itself with the suction cup(s) (1) to the mounting surface.

When the compressed air supply line is open, the VAC is permanently
supplied with compressed air through the hose set.
The vibrator is switched on and off by actuating the 3/2-way manual slide
valve (3).
The hose set HG ... N with DRV is equipped with a throttle check valve (2).
By using the throttle check valve, it is possible to set the pressure applied
to the vibrator and thereby the frequency of the vibrator.

In addition to the standard version N the hose set HG ... S has an econo-
my switch position. With the vibrator switched off the compressed air con-
sumption can be reduced by approx. 30 % in comparison to the standard
version by means of a throttle screw (5). This compressed air reduction is
possible, because the "holding function" does not require the totally avail-
able compressed air. For operating the vibrator, the totally available com-
pressed air is needed and released by the hose set HG ... S.

5 Transport and storage
Observe the safety instructions in Ch. Safety, from page 5 on.
Special conditions of transport are not required.
Due to its own weight, the VAC 40 may only be lifted with a suitable load
handling device. In case it has to be lifted, the VAC 40 is equipped with an
M16 eye bolt.
The VAC are packed and ready for assembly. VAC together with hose set
and vibrator are delivered completely, unless otherwise agreed.
The packaging protects the VAC from transport damage. The packaging
material has been selected from an environmentally safe and technically
disposable point of view and is therefore recyclable.
The return of packaging to the material cycle conserves raw materials and
reduces the amount of waste.
•Store the VAC in a dry and clean environment.
•Protect the VAC from UV-exposures, weather and ozone.
•The storage temperature is between -20 °C and +60 °C.
•Close all openings when re-storing.
•Replace aged, brittle suction cups before renewed start-up.
