The compressor unit draws in atmospheric air and compresses it without oil. It then transports the oil-
free compressed air to the membrane drying unit. The cooler and the membrane dryer extract moisture
from the compressed air. The oil-free, hygienic and dry air is stored in the pressure tank ready for use in
connected devices.
All of the measurement data for the unit comes together in the control (e.g. pressure in the pressure
tank, temperature of the motor windings), where it is then evaluated. Likewise, various settings (e.g.
switch-on/cut-off pressure) can be adjusted, or the unit can be connected via the network to monitoring
software.

5.2 Start-up behaviour
On compressors with an electronic controller, the
compressor units are switched on with a time
delay. The time delay depends on the operating
mode selected on the controller.
Operating mode:
– Eco: 180 s
– Balanced: 60 s
– Boost: 10 s
Alternating control:
The compressor unit with the shortest operating
time since the compressor was connected to
voltage is started. This distributes the operating
time more or less uniformly between the com-
pressor units. If the compressor is disconnected
from the voltage and is then reconnected to the
power supply, compressor unit 1 will start first
again.

Assembly
6 Requirements
The unit must not be set up or operated
within the vicinity of the patients (within a
radius of 1.5 m).
The unit can be installed either at the same level
as the surgery room or on a floor below (e.g. cel-
lar).
Due of the amount of noise generated, we rec-
ommend that the unit is installed in an adjoining
room.
The pipes provided on-site must at least meet
the country-specific requirements for drinking
water.
The compressed air network to which the unit is
connected must be designed for the maximum
pressure of the unit (10 bar).
Further information can be found in our
separate planning information leaflet for
compressed air.
6.1 Installation/setup room
The room chosen for set up must fulfil the follow-
ing requirements:
– Closed, dry, well-ventilated room
– Should not be a room made for another pur-
pose (e. g. boiler room or wet cell)
– If the unit is installed in a machine room, e.g. in
an adjoining room or cellar, the requirements
set out in ISO‑TS 22595 must be complied
with.
NOTICE
Risk of overheating due to insufficient
ventilation
The units generates heat. Possibility of
heat damage and/or reduced service life
of the unit.
❯Do not cover the unit.
❯Install a fan for auxiliary ventilation in
rooms where ambient temperatures
exceed ³40 °C while the unit is in
operation.
≥ 40 °C
6.2 Setup
The following conditions must be taken into
account for installation:
The air is filtered when it is sucked in. This
does not alter the composition of the air.
For this reason it is important to keep the
sucked-in air free of harmful substances
(e.g. do not suck in exhaust gases or
contaminated exhaust air).
– Clean, level and sufficiently stable subsurface
(note the weight of the unit).
– Type plate easy to read.
– Unit easy to access for operation and mainte-
nance.
– Easy-to-access power outlet to which the unit
is connected.
– Maintain sufficient distance to the wall (at least
20 cm).
– The compressed air pipe should be routed as
closely as possible to the place of installation
(note the length of the hose supplied).
6.3 Information about electrical
connections
❯Ensure that the electrical connections to the
mains power supply are established in accord-
ance with current valid national and local regu-
lations and standards governing the installation
of low voltage units in medical facilities.
❯Observe the current consumption of the devi-
ces that are to be connected.

7 Transport
WARNING
Risk of explosion of the pressure tank
and pressure hoses
❯The pressure tank and the pressure
hoses must be vented before they are
stored or transported.
❯Protect the unit against moisture, dirt and
extreme temperatures during transport ("4
Technical data").
❯Always make sure that the condensate collec-
tor chamber is empty before transporting the
unit ("15 Taking out of use").
❯Always transport the unit in an upright position.
❯Only transport the unit using the transport han-
dles provided.
❯Check the unit for transport damage.
8 Installation
8.1 Remove the transport locks
The transport locks only need to be
removed on the Duo Tandem, as the
compressor units are delivered separately
for the Quattro Tandem.
For safe transport, the appliance is securely pro-
tected with two foam blocks and a retaining
strap.
❯Cut and remove the retaining strap.
❯Remove the foam blocks.
❯Check the unit for transport damage.
8.2 Installing the compressor unit
The compressor units only need to be
installed on the Quattro Tandem.
❯Screw the vibration reducers with short threa-
ded bolts into the retaining plate.
