Kurt Zubler
Managing Director
Dear Customer,
We are pleased that you have decided in
favour of a Zubler central extraction
system and do hope you enjoy using it.
Ongoing development of our technology
is based on collaboration with experienced
dental technicians. The focus is on our aim
to make extraction equipment quieter and
more user-friendly. Excellent performance
and cost-effectiveness are essential.
To ensure smooth operation you should
read the operating instructions carefully.
his extraction system is solely
designed for dry dust.
These operating instructions do not
include a detailed description of
installation. It is assumed that the
extraction system has already been
installed in your laboratory by the
technical staff and that the suction
units have been connected up.
No liability claims will be accepted on
the basis of the illustrations or technical
information. We reserve the right to
make modifications, without updating
these instructions.

* The filtered air from the central dust extraction systems must not be returned to the laboratory rooms.
The separation capacity indicated by dust class "M" of the main filter only serves as information concerning
the quality of exit air discharged into the open air.
1.2. Method of operation:
The dust produced at source in the
laboratory passes into the central extraction
system through the piping connected to
the intake port (31). The dust is separated
off in the dust filter cartridge (24). The
dust filter cartridge is attached to the
inside of the filter housing (9). The filtered
air passes via the blower (26), which is
located in the motor housing (7), into the
exit air pipe connected to the air outlet
(29). The air is discharged into the open
air via a noise damper.

2.2. Method of Operation
Some of the laboratory work spaces are
connected to this filter unit via a separate
piping system. A connection is made to
the suction machine via extraction nozzle
68. Owing to this so-called dual-circuit
system it is possible to segregate types
of dust. The EF 5 filter systems can be
used either for pure dirt or for mixtures
of dust containing precious metals. The
aim is to reduce separation costs by
disposing of the main bulk of laboratory
dirt directly and ensuring that dust
containing precious metals has a higher
level of concentration.

3. Operation
3.1 Connecting Up the Suction Machine
Installation of the machine and connection
to the piping system are normally performed
by specialised fitters when the extraction
system is installed. Connect the extraction
pipes coming from the laboratory to the
intake nozzles, item 31 (on the left and
right). Connect the exit air piping system
to the nozzle, item 29. Use the flexible
380 V, 16A connecting cable enclosed in
order to make the electrical connections
between the extraction system and your
building power supply. Plug the coupling
with plug (2) on the extraction side and
the cable connector into the socket of
the 380V building power supply.
Press the connection nipple (18) with the
compressed-air hose (17) into the couling

3.2 Switching On the Suction Machine
Put the Central Extraction System into
operation by turning on at the ON/OFF
power switch (5). Beforehand check to
make sure there is a supply of compressed
air in the extraction system and in the
laboratory. If the compressor system is
only started up at the same time as the
suction machine, the suction units in the
laboratory will be open because the
network is not pressurised. In addition,
make sure the dust container is positioned
correctly and the lever (11) is in a vertical
position. Only then is the extraction
system sealed tight. Before switching on,
please also check to make sure the vacuum
hose (14) is firmly inside the push-fit
coupling of the dust container (12).
Important: The seal (sealing lip) of the
dust filter cartridge is compressed
the first time it is screwed tight. On
account of "settling" the pressure
exerted decreases after a few days.
Therefore, 4 weeks after putting into
operation or changing the filter check
the star grip nut (see section 7.4 on
page 19) to make sure it is firmly in
place, and tighten up if necessary.
(20) of the compressed air network (21)
(5-8 bar). When disconnecting, hold the
connection nipple tightly and retract the
locking mechanism (19) in the direction
of the arrow.
The system must not be operated without
being connected to the compressed air
supply or else the dust filter cartridge
cannot be subjected to automatic
compressed-air dedusting.
To prevent the filter cartridge from
becoming clogged, the compressed air
from your compressed air system must
be oil and water-free. Modern cold air
dryers meet the requirements for
industrial compressed air in accordance
with ISO 8573.1
Filter dedusting start-up delay:
After switching on the extraction system
it takes approx. 5 min for the suction
motor to start up. The purpose of the
time delay is to ensure efficient filter
dedusting without any suction being
applied. During the first few minutes
before dedusting it also ensures that the
laboratory compressor can build up the
required air pressure. After three
dedusting surges the motor starts up and
the extraction system is ready
Note:
This function is not available on all
machines. Particular suction systems
e.g. for schools and universities,
with smaller dust accumulation, are
equipped with different control
systems. Page

4.1 Filter Material
The extraction systems are fitted with
cartridge filters. The filter material used is
certified for dust class M. The permeability
for dust class "M" as per DIN EN 60335-
2-69 is less than 0.1%. A filter certificate
is available on request. The filter material
used is registered under test certificate
no.: 9101201/6210.
Functional Description and
Adjustment of the Suction Machine
Only dry dust may be extracted. Any
liquids which get it inside the
extraction system can damage the
dust filter cartridge beyond repair!
4.2 Dedusting System
To prevent the pores of the dust filter
cartridge (24) from becoming clogged
there is a dedusting system (25) (rotary
air nozzle) inside the dust filter cartridge.
The filter surface is automatically subjected
to compressed air by the rotating
dedusting system at fixed intervals. The
interval is set to 10 minutes by default
but it can be changed by our Customer
4.3 Maximum Mode for Laboratory Cleaning and Pipework Maintenance
You can switch off the automatic control
system by pressing the Maximum button
(8) for maintenance work, which is loca-
ted on the front of your extraction
system and can also be connected to
your laboratory rooms on request. Then
the blower runs up to maximum speed,
and hence maximum suction, for a fixed
period of time (the default is 15 minutes).
If you press the Maximum button again,
the system resumes automatic control
mode. Maximum suction is required
when cleaning laboratory rooms or the
main pipes. For maintenance work
(cleaning the main pipes) read more in
section 7.5 on page 25.
Service on the timer (37). The timer
actuates the valve (36). A compressed-air
cylinder (34) is necessary for the filter
dedusting system. The compressed-air
cylinder is fitted with a pressure-reducing
valve (39), which restricts laboratory
compressed air to 3 bar, and a safety
valve (38) (set to 3.5 bar).
