1.3.2 Exhaust
QThe exhaust can be moved to the left or
bottom of the motor silencer (55) by
swapping the exhaust cover (17) and the
exhaust port (56). Fig. 1.
QThe usage of the bottom exhaust port
should be avoided if possible, otherwise
it may not leave enough space for suction
and compressed air lines.
QThe exhaust hose (socket/pipe) Fig. 8 is
used to route the exhaust air from the
suction system to the installed piping. The
exhaust hose can additionally be used as
an extension or flexible intermediate piece
in the suction or exhaust air line. Item
number: 752/3481
QWe recommend to guide the exhaust air
to the outside. If the length of the duct
exceeds 10m, Ø 110mm pipe should be
installed.
QFor an exhaust into the room, we offer
a diffuser (Fig.9), which reduces the air
velocity and outflow noise. This can be
installed in a suitable position and can also
be connected via a Ø75mm pipe.
Dimensions: 450x300x300 mm

1.3.3 Compressed air
QPlug the enclosed 8mm compressed air
hose firmly into the swivelling connector
on the pressure reducer, Fig.10, take care
to overcome the pressure point of the
sealing.
QNow the quick connector (7mm) can be
plugged into a suitable quick coupling in
the laboratory.

1.4.3 Connecting the control units
QThe AP601 port openers must be connec-
ted to the suction unit via a data bus (Fig.14).
QTherefore use the 3m network cable,
which comes with the AP601.
QThe AP601 is equipped with two RJ45
network sockets, which are used for
interconnection (daisy chaining).
QThe suction unit is also equipped with two
RJ45 network sockets, which only have to
be used both, if there are workstations on
both sides of the suction unit.
It is recommended to route the network
cable parallel to the suction line.
QIf the distance between two neighbouring
AP601 or between an AP601 and the suc-
tion unit is greater than 3m, longer network
cables are required, which are also available
from the Zubler accessory list.

2.3.1 Vacuum levels
QAs long as the power limit of the suction
motor is not reached (depending on
the number of simultaneously opened
workstations), the following volume flows
can be achieved approximately with the 5
factory set vacuum levels:
QVacuum level 5 is the maximum motor
power (no volume control).
QThe specified air volumes are determined
by the attached vacuum and refer to
the port valve diameter of the AP601
automatic port opener.
2.3 Basic functions
QThe suction power of the vacuum levels

QOnce there are AP601 port openers con-
nected, button T4 () on the suction
unit is blocked. Starting the suction is only
possible via the AP601 port openers.
2.3.3 Multi-user vacuum level
QThe multi-user vacuum level is factory set
to level 2. If more than one workstation is
opened, vacuum level 2 is applied.
QThe multi-user vacuum level can be
adjusted with the T1 (-) and T2 (+) keys
and can be saved by pressing T3 (Enter).
2.3.4 Central vacuum level mode
QUsually the vacuum level is defined by the
AP601 port openers. However, under some
circumstances a central vacuum level mode
may be required. With this mode all work-
stations use the same vacuum level regard-
less of the vacuum levels of the AP601
port openers.
QThe central vacuum level can be adjusted
with the T1 (-) and T2 (+) keys and can
be saved by pressing T4 ( ). LED L6 is
lighted. Press T4 ( ) again to disable the

3.1.1 Checking the fill level
QOnce the timer for the dust container has
expired, the LEDs L4 (dust container) and
L5 (service) start flashing. Next time the
suction unit is switched ON, the unit stops
working and the dust container (31) must
be checked as follows:
QLeave the suction unit switched ON
QRemove the door (18) as described in
section 1.2 and lower the clamping lever
(38). The LED L5 (dust container) stops
flashing and is permanently lit.
QPull out the dust container and empty it if
necessary, according to section 3.1.3.
QSlide the dust container back into the
suction unit until limit stop and pull the
clamping lever upwards.
QThe LEDs L4 and L5 are blanked and the
timer is reset.
3.1.2 Adjusting the container timer
QThe dust container timer is factory set to
40h motor running time. Initially you may
have to check the filling of the dust con-
tainer dayly or weekly to evaluate the
expected amount of dust.
QIf the dust container is already filled more
than half after one week, the interval
should be shortened.
QIf the container timer is too short, we re-
commend adjusting it only, if the dust
container is less than 1/3 full of dust once
the timer has expired.
