1 General information
1.1 Function
The DUNOS O50 F - Ex and O90 F - Ex Target Jet Cleaners are orbital target jet cleaners.
They are driven by the cleaning medium. The machines are designed with little dead space
and are produced from certified materials in Germany. The surfaces and their roughness
are constantly monitored during production.
The cleaning medium, filtered according to the relevant regulations, is fed into the target jet
cleaner. The target jet cleaner is either placed directly on the tank flange or placed in the
tank via a support tube or lance. The connections are variable, standard connections are
described in the chapter on “Technical data”. The inflowing medium is fed to a turbine, which
generates an output speed of 10 to 14 min−1 with the downstream gearbox. The target jet
cleaner is driven via a drive shaft. Due to the design of the orbital driven target jet cleaner,
the outflowing jet of cleaning agent is applied to the container wall in the form of a horizontal
eight with high impact. Depending on the type of coating to be cleaned, a user-defined
amount of chemicals must be added to the cleaning medium.
Important: Onlypart of the cleaning medium passes through thegear unit. The main volume
flow is routed via a bypass to the target jet head with the nozzles. This minimises pressure
loss and ensures maximum volume flow for the nozzles.
The target jet cleaners can be operated with various nozzle diameters.
This enables the devices to be perfectly adapted to the cleaning task at hand.
1.2 Proper use
The target jet cleaners may only be operated in closed containers. Operation
outside of a container can lead to severe injury from the high impact of the
emerging liquid jets. The cleaning agent would additionally be widely dis-
persed into the environment.

1.2.1 ATEX zone
In potentially explosive areas of zone 0, 1, 2 & 20, 21, 22, only appliances may be imple-
mented for the application purposes of the design and certified, authorised and designated
by ATEX.
The DO 50 F-Ex and DO 90 F-Ex target jet cleaners are designed for use in the ATEX zones
described and are therefore suitable for gas and dust environments.
The personnel for commissioning and inspection must be appropriately qualified for work in
hazardous areas. Furthermore, the operator must ensure that the contents of the operating
manual are fully understood by all persons involved in the installation, commissioning and
operation of the target jet cleaners described.
Conversions, as well as modifications, to the target jet cleaners are forbidden
and will always lead to the termination of ATEX approval.
Another or derived usage is not deemed to be approved usage and AquaDuna
GmbH & Co. KG is not liable for the arising damage.
The Ex target jet cleaners have been constructed according to the state of
the art and are safe to operate. From faulty operation or improper installation,
hazards to life and limb of persons can arise, to the EX target jet cleaners
themselves and to the operator’s equipment.
1.2.2 Component marking
EX target jet cleaners are marked as equipment according to:
II 1 G Ex h IIB T6…T4 Ga
II 1 D Ex h IIIC T85°C…T135°C Da
the marking is engraved on the Ex target jet cleaner.
The EU type examination certificate number is: TPS 19 ATEX 051981 0018 X

1.2.3 Operating conditions
The following conditions must be observed in order to use the Ex target jet
cleaners in accordance with their intended purpose:
The prevention of ignition sources caused by the cleaning process is the responsibility
of the operator. (TRGS 727)
The Ex target jet cleaners must be integrated into the local equipotential bonding
system. All conductive parts must be earthed or connected to other conductive parts.
The leakage resistance must be lower than 106Ω.
After exchange of the Ex target jet cleaner or the mounting for the supporting pipe
(lance), the leakage resistance must be measured and a value of 106Ω must not be
exceeded.
The assembly instructions (point 4) must be observed!
When installing the Ex target jet cleaner inside a container, e.g. a tank, it should be
observed that the distance of the Ex target jet cleaner to the wall of the container or
fittings is sufficient, so that any contact may be excluded.
The cleaning agent, used for operating the Ex target jet cleaner, must attain at most
80% of its ignition temperature.
If the Ex target jet cleaner is operated in a dust explosive atmosphere, then a maximum
of 2/3 of the minimum ignition temperature of the dust cloud should ever be attained.
The minimum conductivity value of the cleaning agent must not be below 1000 pS/m.
The Ex target jet cleaner must not be powered by gas or steam, as otherwise a
hazardous electrostatic charge within the Ex target jet cleaner can potentially arise. In
order to exclude operation with gas also with the start-up of the pump, the shut-off
device should be situated directly before the Ex target jet cleaner. The piping volume
between the shut-off device and theEx target jet cleaner should be assmall as possible.
All piping should be ventilated.
The Ex target jet cleaner should be operated with a 500 µm prefilter.
The maximum permissible ambient temperature for the operation of the EX target jet
cleaners is 135°C.
The maximum permissible medium temperature is 97°C.
The operator is responsible for observance of the conditions.

1.2.4 Hazards
Ex target jet cleaners are operated with high pressures. We therefore ex-
pressly point out that the instructions in this operating manual must be ob-
served. Damages resulting from non-compliance will not be acknowledged
by the manufacturer.
The target jet cleaner may only be operated in the intended environment. Op-
eration is only permitted in closed containers / rooms. Hazards due to rotating
parts must be observed.
Danger of jamming between the nozzles and the unit body!
Assembly and operation of the Ex target jet cleaners may only be carried out
by instructed, authorised persons.
The target jet cleaner must not be twisted by force at the machine head or the
nozzle disc. This can lead to destruction of the drive. → Image below.
