6. Functional description
The V-Suction units (4) are used with dry suction systems. The advantage is that the suction units
can be installed in any suitable room without paying attention to the arrangement of the wiring (also
in upper floor or basement). The necessary air flow and vacuum requirements are achieved using
the by-pass duct compression principle.
A condensation trap (3) is fitted to the vacuum side of the V-Suction unit (V 250 special accessory),
which collects any condensation that accumulates in the pipe system and removes this externally.
An air-bleed (5) in the condensation trap (only types V 600, V 900, V 1200) protects the V-Suction
unit from over-heating and provides for constant suction performance.
If one of the units has a loss in suction then ca. 300 l air/min. is sucked in via the suction channels.
The speed at entry into the channel is ca. 50 m/s. In the suction pipes the speed of flow is reduced
to 15-20 m/s. This speed is enough to guarantee reliable transport of all dirt particles.
In the hose manifold (2) is a fine filter which retains all larger particles. In the separator unit (1) there
is a reliable removal of all remaining dirt components. By this means only air with no fluid or
particles is transported from the separator to the suction motor. The secretions in the separator unit
flow automatically through the drainage hose into the drainage system of the treatment unit.

Installation
7. Set-up
7.1 Installation room
• The room temperature must not fall below +
10 ° C in winter and in the summer must not
rise above + 40 ° C.
• Installation in special-purpose rooms, e.g. in
heating rooms, must be checked concerning
building regulations beforehand.
• Installation in wet or damp rooms is
1
2
prohibited.
• When installing in a cupboard or similar,
check that there is sufficient ventilation, i.e.
check that air vents are present in the
cupboard. If air flow is insufficient then a fan
should be installed
7.2 Set-up alternatives
A great advantage of dry suction systems is
that the suction unit may be installed in any
suitable room (also in upper floor or
basement) without worrying about the
available plumbing.
• Installation of the suction unit directly onto
the floor (depending on type).
• Installation of the suction unit onto a special
frame and then onto the floor.
• From the wall on a special wall mounting
bracket.
For reasons of hygiene and in order to
avoid both smell and problems of heat
we recommend the exhaust air to be
fed outside the building and to fit a
sterile filter
14
7.3 Condensation trap
Where a condensation trap is present, this
should be fitted first before installation of the
suction unit. Where the suction unit is to be
fitted on the top floor of the building then the
condensation trap, should be fitted at the
lowest point of any plumbing.
Installation instructions for the condensation
trap are delivered together with that unit.
3
7.4 Plumbing materials
Only the following materials may be used
for the pipe system:
Vacuum-sealed HT-drain pipe made from
polypropylene (PP, polypropen), chlorinated
polyvinyl-chloride (PVC-C), unplasticized
polyvinyl-chloride (PVC-U) or polyethylene
(PEh).
The following materials may NOT be
used:
Acrylnitril-Butadien-Styrol (ABS)
and Styrol-Copolymer-Blends
(SAN+PVC)
7.5 Hose material
Only flexible spiral hoses of PVC with spiral
fittings or hoses of this quality should be used
for the drainage and suction systems.
The following materials may NOT be
used:
Hoses which are not capable of
withstanding the dental
disinfectants and chemicals used,
or hoses which are of rubber or full
PVC tubes which are not sufficiently
flexible.
7.6 Pipe installation
• Drainage pipes, e.g. after the condensation
trap, must be installed according to the local
rules and regulations.
The connection between the plumbing
system and the inlet to the suction unit
should be kept as small as possible
and as straigt as possible with no
bends using the flexible hose
supplied. This will avoid unnecessary
vibration on the plumbing system.
8. Electrical Connection
Before commissioning check that the electrical
supply conforms with that on the appliance
label.
Electrical connection to the power supply must
be carried out by inserting into the circuit a
universal circuit breaker (universal switch or
universal line safety switch (fuse)) with >3mm
contact gap.
The suction unit may be connected via the
control system to an external junction box.
Fuse rating: 16 AT

Care
10. Disinfecting and cleaning suction units
After every treatment
should be sucked through the system; through
both the small and the large suction hoses,
even if only the saliva suction hose was used
during treatment.
The cleaning effect is increased
considerably by using the larger
suction hose.
a glass of cold water
11. Maintenance
The V-Suction unit itself requires no
maintenance.
The exhaust from the suction unit contains
bacteria. As the separation techniques within
the suction unit are only designed to remove
fluids and particles, germs which are present
are sucked through the system. For this
reason we recommend that a sterile filter be
fitted into the exhaust sytem and that this filter
be changed at least once a year.
Before midday break and at the end of the
day
a non-aggressive and non-foaming
cleaning and disinfecting agent (e.g. Orotol
Plus) should be used to clean and disinfect
the suction system.
Do not use a foaming cleaning
agent, as this can damage the
suction unit.
The suction unit may not be used to
extract solvents such as Acetone or
anything similar. These agents
attack the plastic and rubber parts
of the unit.
Further information can be found in the
instruction booklets "Disinfection and Cleaning
of Suction Units“, order number 9000-605-10
and in "Cleaning Instructions for contaminated
Suction Units", order number P007-235-01.
Disposal
12. Appliance disposal
The machine may be contaminated.
Please inform the waste disposal
contractors in order that they can take
the appropriate safety measures.
Non-contaminated plastic parts of the
suction unit can be disposed of for
recycling.
The control units, electronic PCB and other
components should be disposed of as electric
waste. The remaining metal parts (e. g. turbine
housing) should be disposed of as metallic
waste.
If returning the appliance, e.g. to your local
Depot or to Dürr Dental, make sure that all
connections are closed.
