2 Safety
Dürr Technik has developed and constructed the
units in such a way that danger is to a large
extent excluded if the units are used as intended.
Nevertheless, residual risks can remain. You
should therefore observe the following notes.
2.1 Intended use
The unit is intended for the compression of
atmospheric air. The unit has been designed for
operation in dry, ventilated rooms. The unit must
not be operated in a damp or wet environment.
Its use in the vicinity of gases or flammable liq-
uids is prohibited. Only operate the units in a sta-
tionary, upright position.

Product description
3 Overview
The unit draws in atmospheric air and com-
presses it. The oil-free compressed air is then
transported to the pressure vessel. The oil-free
and filtered air is made available to the consum-
ers in the pressure vessel.
If compressed air is removed for a consumer, the
pressure in the vessel drops. When the switch-on
pressure is reached, the unit is automatically
switched on again via the pressure switch. When
the cut-off pressure is reached, the unit is auto-
matically switched off. A safety valve prevents the
maximum permissible vessel pressure from being
exceeded.

4.4 Instructions for use for the pressure vessel (explanation by Behälter-
Werk Burgau GmbH)
The pressure vessel must only be used in accordance with the aforementioned intended purpose and in
accordance with the specified technical data. Other forms of use are not permitted for reasons of safety.
The pressure vessel has been designed in accordance with Directive 2014/29/EU and has been manu-
factured as a single component without safety equipment for the application area detailed above.
The unit has been designed for internal pressure loads.
Before commissioning, the vessel must be fitted with the necessary safety equipment such as a pres-
sure gauge and safety equipment designed to protect against overpressure, etc. These parts are not
included in our scope of delivery.
No welding work or heat treatment may be carried out on the pressure-retaining walls of the vessel. It
must be ensured that the internal pressure does not exceed the operating pressure PS specified in the
labelling on the vessel during operation. However, this pressure may be temporarily exceeded by up to
10%. Vibration stress that would be damaging for the pressure vessel and corrosion on the vessel must
be prevented using appropriate measures.
The assembly or installation of the pressure vessel must be carried out in such a way that safe use of
the vessel is ensured (e.g. no rigid connection to the floor or machine base frame without vibration
dampers).
The operating instructions to be provided by the equipment supplier must include the following informa-
tion in accordance with the equipment fitted:
– a) Instructions for draining the condensate
– b) Instructions and information about maintenance to ensure safety of use
The supplier must also specify whether the pressure vessel, when fully equipped for operation, has to
undergo an acceptance test before commissioning. The supplier/owner must observe the laws and reg-
ulations regarding the operation of the pressure vessel that apply in the country of operation.
Load changes and capability of sustained operation (fatigue strength) – see "4.3 Pressure tank" Notes.

Assembly
5 Requirements
5.1 Installation/setup room
The room chosen for set up must fulfil the follow-
ing requirements:
– Closed, dry, well-ventilated room.
– Should not be a purpose-made room (e. g.
boiler room or wet room).
– Set up the unit on a clean, level and sufficiently
stable surface (take the weight of the unit into
account).
– Set up or install the unit so that the type plate
can be easily read and the unit is easily acces-
sible for operation and maintenance.
– Set up the units so that the socket to which
the units is connected is easily accessible.
– Room temperature: +5°C to +40°C.
– Ensure that there is sufficient distance to the
wall so that the air can flow in and out without
any obstruction.
The air is filtered when it is sucked in. This
does not alter the composition of the air.
The source of the air taken in should be
free of any harmful substances (e.g. do
not draw in air from an underground
garage or directly next to a suction
machine).
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.
❯Air must be able to flow in and out
unobstructed.
❯Ventilation openings must be suffi-
ciently large.
❯Installed units may require an inde-
pendent ventilation system in unfavour-
able cases.
The unit must only be operated on a stable, even
base. The unit must not be used as a climbing
aid. Danger of breakage! Place a collector tray
under the condensate drain (14) on the rear of
the unit to collect any condensate that is blown
out.

6 Commissioning
6.1 Remove the packaging
The unit is securely protected with packaging
material to ensure safe transportation.
❯Remove the packaging material.
❯Remove the protective film.
❯Check the unit for damage in transit.
❯Only lift the unit using the transport handles
and/or from the bottom.
6.2 Establishing the compressed
air connection
The unit has a 7.2 mm quick-release coupling on
its outer side. The matching hose nozzle for a
connecting hose with an internal diameter of
6 mm is included in the scope of delivery.
CAUTION
Damage to the quick-release coupling
if the cover of the unit is open
The quick-release coupling can be dam-
aged due to high compressive forces
during connection of the pressure hose.
❯The cover of the unit must be closed
and locked.
Quick-release coupling – operating panel
The compressed-air connection to the
pressure reducer has a constant pressure
(set at the factory) of 0 – 6 bar.
The pressure can be adjusted via the
pressure reducer in the unit – see "7.3
Setting the pressure reducer".
❯Compressed air is extracted at the quick-
release coupling (7.2 mm) via a hose adapter
piece on the operating panel of the unit.
❯Secure the pressure hose to the hose adapter
piece using a hose clip.
❯Connect the hose adapter piece to the quick-
release coupling.
Article 8012100011 - Bulkhead fitting
❯Air is extracted at the bulkhead fitting G 1/4".
Tighten the bulkhead fitting with a maximum
tightening torque of 15 Nm.
6.3 Condensate
When air from the surrounding atmosphere is
compressed, different amounts of condensate
will accumulate in the pressure vessel depending
on the humidity and temperature of the air. This
condensate is collected via the integrated con-
densate separator, which is located between the
pressure vessel and the compressed air connec-
tion. As soon as a certain fill level is reached in
the condensate separator, the condensate is
drained off to the outside via the condensate
drain.
❯Place a collector tray under the condensate
drain.

6.4 Electrical installation
❯Connect the power cord to the mains socket
on the rear of the unit
❯Connect the power cord to a properly installed
mains socket with PE conductor.
❯Route the power cord in such a way that it is
not under any mechanical tension.
❯Before commissioning, verify that the power
supply voltage complies with the voltage speci-
fications of the type plate.

DANGER
Risk of electric shock due to dam-
aged power cord or plug
Electric shocks can cause severe inju-
ries.
❯Do not start up the unit if the power
cord or plug is damaged.
❯Replace the damaged power cord.
6.5 Overtemperature protection
The motors in the units are equipped with a tem-
perature switch that switches the unit off if it
overheats. If this happens, you will first need to
determine the cause of the fault and then remedy
it.
If the unit is switched off via the tempera-
ture switch, the fan of the unit will con-
tinue to run.
NOTICE
Automatic start-up of the unit after
cooling down
❯Allow unit to cool down
6.6 Checking the safety valve
The safety valve must be checked/vented when
the unit is started up for the first time and once
a year after that.
At the factory, the safety valve is set to 10
bar (1 MPa) or 8 bar (0.8 MPa) (depend-
ing on the maximum pressure), inspected
and stamped (see also "4 Technical
data").
DANGER
Risk of explosion of the pressure ves-
sel and
pressure hoses
❯Do not change the safety valve set-
tings.
WARNING
Risk of damage to the safety valve
Risk of explosion of the pressure vessel
and pressure hoses due to a defective
safety valve
❯Do not use the safety valve to vent the
pressure vessel.
❯Switch on the unit at the pressure switch and
fill the pressure vessel to the cut-off pressure.
❯Rotate the cap of the safety valve a few turns
anti-clockwise until the valve begins to blow
off. Only allow the safety valve to blow for a
short period.
❯Turn the cap clockwise as far as it will go.
The valve is closed.
