mented after studying section 4 thoroughly.
Avoid the dismantling of any factory-mounted parts, sin-
ce it impedes the commissioning of the equipment.
All electrical installations must be carried out by an
authorised electrician.
1.1 Danger
Explosive media – the HVU is not suitable for the extra-
ction of aluminium dust, flour, textile dust nor sawdust or
other media, which is connected with danger of explosi-
on, without specific approval from Geovent A/S. Please
ensure not to extract any of the above mentioned media,
since an explosion could be deadly dangerous.
Dismantling parts on the HVU whilst in operation could
be deadly dangerous.
Always disconnect the HVU from the mains, when
mounting parts or servicing the Unit.

The sound level depends on several factors; For examp-
le where the High Vacuum Unit is placed (indoors/out-
doors), the size of the room, the temperature of the
surroundings, the acoustics and also the connection
(hose><pipe) of the Unit has an effect on the sound le-
vel.

2.0 Installation
The HVU should be installed indoors, for example in an
engineering room with good ventilation in order to secure
perfect operation. For outdoor installation, always pla-
ce in an open shed as a minimum. THE SURFACE
TREATMENT OF THE HVU IS NOT SUITABLE FOR
OUTDOOR APPLICATION, SINCE THE RISK OF WA-
TER PENETRATING THE CYCLONE IS INCREASED
AND FURTHERMORE, THE ELECTRONICS COMPO-
NENTS MAY NOT FUNCTION IN FROSTY WEATHER.
The HVU is supplied in complete/assembled condition
and it has been pre-programmed, ready for connection
to the mains.
Before mounting, please make sure that the optimum
installation area is selected. Should it be placed indoors
or outdoors? Is there space enough for the satisfactory
installation and service of the HVU? What about opti-
mum connection possibilities for piping and automatics?
If at all possible, please avoid bends just before the inlet
and after the outlet, since otherwise it could reduce the
capacity of the HVU. For outdoor mounting, please take
the following aspects into consideration: Any noise nu-
isance for the neighbours, defects due to frost and keep
the engine out of heavy showers. Therefore, we recom-
mend building a shed around the HVU in order to protect

it from the weather and to shield against noise.
Example: Below a noise shield has been built around the
HVU and a protection roof against heavy showers.
The following installation should only be carried out by
a trained fitter.
Procedure:
1. The HVU is placed on a solid foundation (e.g. on a
concrete floor), where there is no danger of vibration
transmission. Also, please ensure that the filter can
be exchanged (i.e. as a minimum a free height of 800
mm is required).
2. Connect the piping to the HVU. On the inlet side, the
pipe may be fixed by means of a spring lock system.
Remember to seal the connection with filler and/or
tape!
3. In order to secure free mixing, the outlet should be
taken two metres up above the roof top (up in the air)
with an air velocity of 8 m/s as a minimum.
4. The whole plant/piping system should always be tho-
roughly checked for leaks, which should be sealed.
The plant may not be taken into operation for 24 hours.
Connection of the fan to the mains:
5. The connection of the electric components of the
HVU should only be carried out by an authorised ele-
ctrician.
Connecting the compressed air:
1. Connect the clean and dry compressed air. There
must be a pressure regulator. We recommend you to
install a water separator just before the HVU.
2.1 Mounting of optional equipment
Mounting of frequency converter
It is possible for us to deliver with frequency converter
and / or pressure control. See for external manual pres-
sure control.
For setting options for external frequency converter,
please refer to the supplied, separate manual.
Automatic start/stop
External start/stop (e.g. micro switch by the quick-action
coupling/connection or on/off-button on the Energy Arm)
There is a timer an manuel, which makes HVU’en to
swits off automatically after 30 minutes.
2.2 Trial run – exact adjustment
When the installation has been completed, please check
whether there is any vibration or noise nuisance from
the HVU. Please control that the complete plant is totally
tight. If any creaking noises are emitted, please locate
the leakage and seal it with filler. Furthermore, we re-
commend checking whether the HVU supplies the volu-
me of air, for which the equipment has been dimensio-
ned. Measure the air volume and ensure that it does not
exceed the amperage of the engine.
Vacuum security
The vacuum secury is adjustment from factory. We re-
commend that you readjust the vacuum securit subse-
quently.
Adjustment of the Vacuum security
Adjusted so that the valve does not open during normal
running, but opens at blocking.
1. Adjust to loosen or tighten the spring.
2. Then buckles to lock nut to secure the the spring po-
sition.

3.0 Application – user instruction
The HVU may not be in operation for longer periods of
time (more than 45 min.) without opening the connec-
tions in the Channel Duct System, since otherwise the
pump will superheat and break down. Optionally, use
the built-in start/stop function.
Use
When you are finished using the unit, keep the flap open
in 1-5 seconds so that the particles are sucked away
from the vertical pipe, so that it does not fall into the
head of the operator, the next time the system is in use.
4.0 Maintenance
At least once annually, the whole point suction plant
should be overhauled by an authorised serviceman.
Periodic maintenance:
• All electric parts should be checked annually.
• In principle, the vacuum pump/engine is main-
tenance-free due to the factory-mounted com-
pletely closed special ball bearings, which do
not require any maintenance. Exchange of worn
bearings should only be carried out by an elec-
tro-company.
4.1 Exchange of filter medium
The collection bucket should be emptied when approx.
two thirds of it is full, since otherwise it may further load
the filter medium. The filter medium should be exchan-
ged after approx. 4,000-8,000 hours of operation or max.
4 years. Partly, this depends on the load on the filter, for
example whether it has been used in connection with
welding or grinding, etc.
Procedure:
1. Disconnect the Unit on the repair switch. Please en-
sure that the switch cannot be activated during the
service operation.
2. Disconnect/dismantle the compressed air connecti-
on.
3. Before dismantling the dusty filter, it is important that
the service technician is equipped with the necessary
personal safety outfit, i.e. breathing mask and gloves,
which comply with the rules of the Working Environ-
ment Service regarding work with polluted dust.
4. Subsequently, the collection bucket is dismantled by
means of the fixed spring locks. Now, with care the
bucket may be taken out. The contents of the bucket
are now to be destroyed in an environmentally sound
manner in accordance with the current rules.
5. The bucket is returned and fixed under the cyclone.
6. The top/lid of the cyclone is dismantled by uncoupling
the spring lock, and then the lid with the compressed
air tank is removed. Make sure first to disconnect the
supply of compressed air and the power supply and
not to damage the compressed air tank, when it is put
aside.
7. Subsequently, with a 17 mm box spanner remove the
three M10 bolts, which attach the filter medium to the
Unit.
8. The polluted filter medium is carefully lifted up and
placed in a large rubbish bag, which is then properly
sealed up.
9. The new filter medium is inserted and fixed to the
Unit with three 10 mm bolts.
10.The top/lid is carefully returned and fixed with a spring
lock. (Remember to connect to power and compres-
sed air again!).
11.Subsequently, the polluted filter medium is sent to
destruction at the nearest waste disposal plant.
4.2 Trouble shooting
In case of problems with reduced pressure or volume of
air, the points mentioned below may be followed when
attempts are made to solve the problems:
The volume of air or the pressure has fallen to below
the indicated volume/pressure.
• Wrong direction of rotation of the fan wheel. May be
caused by wrong electrical installation. Please doub-
le check the direction of rotation. Change two pha-
ses.
• The channel system is not tight.
• Poor inlet/outlet options close to the vacuum pump
may reduce the capacity (e.g. 90° bend just before
the inlet).
• Damaged wheel.
• The rate of rotation has been set to a lower level.
• If the temperature deviates substantially from the la-
boratory measurements, where the temperature was
20°C with an atmospherical pressure of 101.4 kPa.
• The dampers have not been properly adjusted.
• The channel or the Unit has been blocked by a
screwdriver, for instance.
Vibrations and noise.
• The foundation is not level/stable.
• Elements coming from outside have penetrated the
Unit/channel system.
• Damaged wheel or engine.
• The wheel is loose.
• The wheel is running in the wrong direction.

5.1 Pipes and fittings
Start by loosening the 2 bolts so you can easy connect
the pipe. Do NOT, under any circumstance, lubricate the
pipes or rubber with any type of oil or grease.
Metal flap valve type ø50 - ø50 is secured by inserting it
into the pipe and then tightened by tapping it in. As show
in the picture below.
We recommend that you fasten the valve with a small
screw through the pipe and the valve.
Basically, the flap valve is for mounting in pipes.
It is in many cases possible to mount it in branch pipes,
bends and by filing the tube on the inside. Then it is pos-
sible to tap in the flap valve.
This may not always be possible.
