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 Lite is supplied in complete/assembled condi-
tion and it has been pre-programmed, ready for conne-
ction 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 nuisance for the neighbou-
rs, defects due to frost and keep the engine out of hea-
vy showers. Therefore, we recommend building a shed
around the HVU in order to protect it from the weather
and to shield against noise.
The following installation should only be carried out by
a trained fitter.
Procedure:
1. The HVU Lite 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 Lite. 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 electrician.
6.For connection options, please refer to the diagram on
page 6.

Måltabel
2.0 Installation
HVU Lite’en bør installeres indendørs i f.eks.
teknikrum med god ventilation for fejlfri drift.
OVERFLADEBEHANDLINGEN PÅ HVU LITE’EN
ER IKKE EGNET TIL UDENDØRS PLACERING,
DA RISIKOEN FOR VAND I CYKLONEN ØGES,
RISIKO FOR RUST PÅ UNIT, SAMT AT
ELEKTRONIK-KOMPONENTERNE IKKE
FUNGERE I FROSTVEJR.
Inden montering, overvej da først det optimale
installationsområde. Er der plads til at der kan
udføres tilfredsstillende installation/ service af
HVU-Lite´en? Er der optimale tilslutningsmulig-
heder for rørføring og automatik? Undgå for så
vidt muligt bøjninger umiddelbart før indsuget og
efter afkastet, idet dette ellers vil nedsætte
ydeevnen for HVU Lite. Ved udendørs montering
skal der tages højde for evt. støjgener hos
naboer, fejl grundet frost og for at motoren undgår
regn. Derfor bør der opbygges skur omkring HVU-
Lite der skærmer mod støj, vejr og vind.
Følgende installation bør kun ske af uddannet
montør.
Fremgangsmåde:
1. HVU-Lite’en placeres på et solidt fundament
(f.eks. cement gulv), hvor der ikke er
mulighed for at vibrationer overføres. Der
skal desuden tages højde for om man kan
foretage filterskift (dvs. at der minimum er
800 mm frihøjde.)
2. Rørføringen tilsluttes HVU-Lite’en. På
indløbssiden kan røret f.eks. fastgøres ved
hjælp af et snaplåsesystem. Husk at tætne
samlingen med fugemasse og/eller tape!

2.1 Mounting of optional equipment
Mounting of a repair switch
A repair switch must be connected in order to comply
with the EN 60 204-1 standard, according to which a
manual switch must be fitted. Typically, the switch will be
placed 2 – 3 metres from the Unit and it must be clearly
visible.
Mounting of control panel, with build in frequency
inverter and PID regulation
Please see separate manuals for specific details.
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 lea-
kage and seal it with filler.
Furthermore, we recommend checking whether the HVU
supplies the volume of air, for which the equipment has
been dimensioned. Measure the air volume and ensure
that it does not exceed the amperage of the engine.
3.0 Application – user instruction
The HVU should not be in operation for longer periods of
time (more than 15-30 min.) without opening the valves.
There is a built in vacuum safety valve, which should en-
sure the motor from meltdown, but we don’t recommend
testing it for longer periods of time, in case the unit is
placed in a warm location.
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 maintenan-
ce-free due to the factory-mounted completely closed
special ball bearings, which do not require any mainten-
ance. Exchange of worn bearings should only be carried
out by an electro-company.
• The bin should be changed when ever it is full. The bin
sensor should give an alarm signal to the control panel.
Once annually this procedure should be tested for fun-
ctionality.
• We recommend that the cleaning cycle is activated at
least once a day, in order to ensure longer living time on
the filters.
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 ser-
vice operation.
2. Disconnect/dismantle the compressed air connection.
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 Environment
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 man-
ner in accordance with the current rules.
5. The bucket is returned and fixed under the cyclone.
