6. There is a water separator and pressure reduction
built into the unit.
Control panel
Before putting into service:
During transportation, the control panel is exposed to
vibrations etc. In addition, dust may enter the cabinet.
During installation and commissioning, dust may also
enter the cabinet.
Therefore, before the control panel (and the installation
it is part of)
part of) is put into use, all components should be checked
for dust, which should be removed.
The checklist below can be used:
1. Visual inspection.
2. Clean/vacuum the control panel if necessary. Do not
blow compressed air into the control panel.
3. Check/tighten the electrical connections with the cor-
rect torque according to the manufacturer’s instructi-
ons.

5.3 Checking and testing the system
After installation, check if there is any vibration or sound
disturbance.
Check that the whole system is completely tight. In case
of squeaking, the leakage should be localized and sea-
led with sealant.
It is recommended to check whether the HVU delivers
the air volume for which the system is dimensioned.
Therefore, measure the air flow and make sure that it
6.1 After installation
Check the installation according to chapter 5.3.
7.0 Control, test and maintenance
7.1 Control
Check the installation according to chapter 5.3.
7.2 Maintenance
The entire system should be inspected at least once a
year by a qualified service technician.
For all work on electrical installations, the safety switch
MUST be disconnected and locked BEFORE starting
work.
Periodic maintenance:
• All electrical parts should be checked annually.
• The side channel blower is in principle maintenance
free due to the factory sealed special ball bearings.
Replacement of worn bearings should only be carried
out by a qualified service technician.
Control panel
Periodic check:
The control panel should be subjected to a control panel
test at least once a year.
The checklist below can be used:
1. The control panel MUST be voltage free BEFORE
starting any maintenance work.
2. Visual inspection, both internally and externally.
3. Clean the control panel, both inside and out, being
careful, especially around vents and  lters.
4. Inspect the electrical connections for discoloration
due to high temperature. (May occur as a result of
increased resistance due to a poor/loose connection)
If discoloration is found, clean the contact points and
make the connection correctly. Replace the compo-
nent if necessary.
5. Check/tighten the electrical connections with the cor-
rect torque according to the manufacturer’s instruc-
tions.
6. Tighten the mechanical connections.
7. Inspect for damage to the paint and repair if neces-
does not exceed the motor’s ampere rating.
Vacuum protection
The valve is roughly adjusted at the factory.
The valve must be readjusted at the installation.
Adjusting the Vacuum fuse
Adjust so that the valve does not open during normal
operation, but opens when blocked.
Adjust to loosen or tighten the spring.
6.0 Commissioning
The HVU must not run for longer periods (max. 15-30
min.) without open outlets in the duct system, otherwise
the side channel blower will overheat and break down.
If necessary, use the built-in start/stop function.
After use, it is recommended to keep a fl ap open for 1-5
seconds, so that particles are sucked away from the ver-
tical piece, and thus do not fall down the next time the
system is used.

sary.
8. Check switches and circuit breakers.
9. Maintain adequate IP rating: Inspect gaskets for dam-
age and replace it if necessary.
10. In general, each component should be maintained
according to the manufacturer’s instructions.
11. Verication. Perform measurements and tests ac-
cording to EN60 204-1, chapter 18.
12. SRP/CS: Check all safety-related parts of the control
system. Note: SRP/CS should be checked more of-
ten than once a year.
13. If components that are part of the SRP/CS have
exceeded their expected lifetime, they must be re-
placed - regardless of their condition.
14. If the control panel has been exposed to extreme
conditions (e.g. due to lightning, re, water dam-
age), all defective material must be replaced and the
above procedure performed.
7.3 Replacing filter
7.3.1 Emptying of bucket
Emptying of the collection bucket should be done when
it is approx. 2/3 full, otherwise it can strain the filter me-
dium.
If the bucket contains sharp or very heavy items, the bag
may tear before it is full. Change it in good time so that
the bag does not tear when the bucket is emptied.
Procedure:
1. Disconnect the power at the breaker switch. It should
be ensured that the curcuit breaker cannot be acti-
vated during service.
2. Disconnect/remove the compressed air connection.
3. Wait 5 minutes for the dust to settle in the bucket.
4. Before dismantling the dusty filter or emptying the
bucket, it is important that the service technician wears
the necessary personal safety measures, such as re-
spiratory protection and gloves that comply with rele-
vant regulations for working with contaminated dust.
5. Take the ramp down.
6. Lift up the handle and pull the bucket out of the cabi-
net.
7. Empty the bucket, then seal the bag securely.
8. Insert a new bag. Slide the bucket back under the
cyclone, press the handle down to lift the bucket up
under the cyclone again.
7.2.2 Replacing the lter media
The filter media should be replaced after approx. 4,000-
8,000 hours of operation or max. 4 years. This depends,
for example, on the load on the filter.
1. Disconnect the power at the repair switch. Ensure that
the switch cannot be activated during service.
2. Before dismantling the filter cartridge, it is important
that the service technician wears the necessary per-
sonal safety measures, such as a respirator and glo-
