2 Safety
Designated use:
Vacuum fixing devices of series VAC are
used for quick fastening of vibrators to
smooth and, to a limited extent, also to
rough and curved surfaces.
They are used in combination with vibra-
tors for the emptying of transport contain-
ers or drums, for the cleaning of pipes etc.
Vacuum fixing devices are used where
conventional fastening methods for vibra-
tors fail, frequent relocation of vibrators is
required and welding or bolting is not pos-
sible.
Any other use is considered improper use.
There are no built-in safety devices.
Qualification of the personnel:
Assembly, start up, maintenance and
repair of the impactors must be
performed only by authorized qualified
personnel.
Any handling of the pneumatic impactors
lies within the responsibility of the opera-
tor.
Accessories which ensure the correct
operation and safety must provide a
protection type required for the specific
use.
CAUTION
kÉííÉêVibration does not assume liability for damage or injury resulting
from technical modifications to the product or failure to observe the

DANGER
Source of danger:
Faulty hose connections.
Possible consequences of non-observance:
Apressurized hose coming loose can cause se-
vere injury.
Avoiding the danger:
The hose lines must be securely connected. This
must be checked at regular intervals and the
screw connections have to be retightened if nec-
essary.
DANGER
Source of danger:
Vibrators bolted to vacuum fixing devices may
come loose by the effect of vibration.
Possible consequences of non-observance:
Falling parts can cause damage to persons and
material.
Avoiding the danger:

4 Design and Functioning
Vacuum fixing device
A vacuum fixing device mainly consists of a base
plate, a 2/2-way ball valve, a vacuum nozzle and
suction cups. When operating the 2/2-way ball valve
the vacuum nozzle generates a vacuum. By this the
suction cups of the vacuum fixing device adheres to
the mounting surface by suction.
Functional unit
Hose set, vacuum fixing device and vibrator togethe
r
form a functional unit. The vibrator is tightly bolted to
the vacuum fixing device. Vibrator and vacuum fixing
device are supplied with the necessary energy (com-
pressed air or nitrogen) through the hose set.
The hose set is normally available in two different designs:
Hose set "Standard" HG .. N and hose set "Economy Air Supply" HG .. S:
Hose set HG ... N
The vacuum fixing device (opened main valve - cus-
tomer) will always be under pressure, when the
pressure is applied.
The vibrator is switched on and off by actuation of
the manually operated 3/2-way slide valve.
Hose set HG ... S
In addition to the standard function (see hose set
"Standard" HG .. N) the hose set „Economy Air
Supply“ HG .. S has an economy switch position.
With the vibrator switched off the compressed air
consumption can be reduced by approx. 30% in
comparison to the standard version by means of a
throttle. This compressed air reduction makes
sense, because the "holding function" does not re-
quire the totally available compressed air. The total-
ly available compressed air is only needed for op-
eration of the vibrator.
Hose set HG with throttle control valve
Both versions of the hose-sets (N and S) are
available with throttle control valve (DRV) and
recommended by kÉííÉêVibration.
Means of this valve, the pressure which is ap-
plied to the vibrator may be adjusted. Thus, there
is the possibility of the speed of the vibrator and
the impact frequency of the vibrator to adjust.

5 Transport and Storage
IMPORTANT
Check the packaging for possible signs of transport damage. In the event of
damage to the packaging, check that the contents are complete and undamaged.
If there is any damage, inform the shipping agent.
Packaging
The vacuum fixing devices are packaged
ready for commissioning. The type desig-
nation is stamped (8 VAC, VAC 10, VAC
11, VAC 12 and VAC 13) or engraved
(VAC 15 VAC 20 VAC 30 and VAC 40) on
the base plate.
When ordering a vacuum fixing device with
hose set and vibrator these components
are completely assembled, unless other-
wise agreed. Special transport conditions
are not prescribed.
The packaging protects the unit from
transport damages. The packaging materials
have been selected on an environmental
and disposal-friendly basis and are there-
fore recyclable.
Recycling packagings reduces raw material
consumption and waste volume.
Storage
Protect the vacuum fixing devices from
excessive exposure to UV radiation,
weathering and ozone.
The vacuum fixing devices should be
stored in boxes in a dry and clean envi-
ronment. When restocking all openings
must be closed.
The storage temperature should be
between -10 and +25°C. (This does not
apply to the operating temperature).
After 4 years of storage all plastic and sili-
cone components must be replaced before
using.

6 Installation
CAUTION
Make sure the compressed air supply is
switched off during installation or any other
work on vacuum fixing devices, vibrator or air
supply lines.
Complete vacuum fixing devices with hose
set and vibrator are directly ready for oper-
ation after connection to compressed air.
If ordered separately, hose set and vibrator
must first be assembled.

DANGER
Not every pneumatic vibrator is suitable for the vacuum fixing device. With drill pat-
terns different to the ones for the above listed units the internal pilot bores may be
damaged. The above mentioned combinations (fixing device/vibrator) have been
tested and can be used without any limitations.
When choosing a different vibrator a prior consultation is required.
Use screw retentions and nuts to fasten the vibrator. Use a liquid screw retention
agent (e.g. Loctite) against loosening. (If you use a VAC with a PKL, it must be
mounted with the prescribed NBS fixing kit!)
Use tightening torques according to the following table.
Higher tightening torques may cause fracture of screws or tearing of threads. In-
adequate screw connections may cause loosening of units by vibration.
This can cause damage to persons and material!

15
Recommended mean tightening torques for screws of quality 8.8
(screws as supplied, without additional lubrication):

M 8 23 M 16 190
M 10 48 M 20 380
IMPORTANT Vibrators must be cautiously and properly fastened. The fastening screws for the
vibrator must be retightened or checked after 1 operating hour.
VAC 8, VAC 10, VAC 11 and VAC 12
Installation of the Vibrator:
In order to mount vibrators
NCT two tapped blind holes
must be drilled.
If a compressed air operated
piston vibrator of series NTS
or NTK is to be mounted, we
recommend the use of an
adapter plate.
Alternatively one hole must be
drilled into the suction cup and
the tapped hole sealed with a
suitable sealing agent.
For the size Xrefer to the op-
erating instructions for the re-
spective vibrator.
IMPORTANT
When drilling blind holes make sure not to drill through the suction cup (rubber).
However, if this should happen, you must seal the tapped holes with a suitable seal-
ing agent, as otherwise no vacuum can be generated.

screws acc. to DIN 7991 are required. The
assembly can be performed as follows:
1. Unscrew the suction cups.
2. Determine and mark the necessary bore
holes (commonly used bore pitches
have already been marked with a centre
punch, see template VAC 15 and VAC
20).
3. Drill through-holes (diameter depending
on type of vibrator - see operating in-
structions for vibrator).
Countersink bores from bottom side of
base plate (side of suction cup) acc. to
DIN 74-Bf....
4. Fasten the vibrator using the specified
socket head cap screws. For this pur-
pose use common screw retentions.
5. Assemble the suction cups in the correct
position.
