Table 2.1-1: Application of TANKO-JX (Equipment Group II) in Ex Atmosphere
For the intended use, also observe the additional information of the Ex marking on the nameplate of the
device (see Section 2.5.3 Marking for Explosion Protection).
NOTE ON EXPLOSION PROTECTION
The area of application of the device must always be adapted to the corresponding
operating conditions and the materials in contact with the product. These materials must
be selected so that there are no reactions between them and the cleaning medium or the
substances in the container to be cleaned, which could impair explosion safety.
It must be ensured that no hybrid mixtures can develop in the container or in the
environment (a hybrid mixture is a mixture of air with flammable substances in different
aggregate states, e.g. gas/vapor and dust)
If this is not observed, the explosion protection could be invalidated.
The device was developed, engineered and built exclusively for industrial and commercial use. It must
not be used for private use.
The device is constructed so that it can be operated safely within the specified technical parameters
(see Section 3.3 Technical Data).
In all cases, the operating company must check whether the device is suitable for its application.
Locations for containers in which the device is to be installed are usually closed spaces. In different
setups, the operating company must ensure the protection of the device from harmful weather and
environmental influences while maintaining the specified application limitations/conditions (see
Section 3.3 Technical Data).

2 Safety Translation of the original operating/installation instructions 2021/04 9/149
In the process, the following must always be observed:
 Only operate the device when installed in a closed container.
 Never direct the cleaning jet or torrent from the device at persons.
 Protect the device from freezing (e.g. risk of frost from possible residual water).
 Use a suitable filter system in the supply line for the cleaning medium.
 Operate the device only within the approved parameters (see Section 3.3 Technical Data). If
necessary, appropriate monitoring and limiting systems (e.g. for pressure and temperature) should
be implemented.
 Only cleaning media that are compatible with the materials of the device may be used (see Section
3.4 Cleaning Media).
 The installation position of the device (see Section 5.2.2 Installation Position).
 The device may generate vibrations when cleaning the container. Any other vibrations must be
avoided (see Section 7.4.1 Maintenance Intervals).
WARNING
Danger from incorrect use of materials/media!
The materials/media to be used for the intended operation of the device are procured
and utilized by the operating company of the device.
If unsuitable materials/media are selected, strong chemical reactions could lead to fatal
injury or severe physical injuries.
 The proper selection and treatment of these materials/media is solely the
responsibility of the operating company.
 When selecting the materials/media, make sure that the permitted technical
parameters of the device are NOT exceeded.
 The cleaning agents and media must be approved for all of the materials of the device
(e.g. washers, bushings) and for the substances in the container to be cleaned which
come into contact with them.
 Adhere to the specified chemical limits for use in the material data sheets.
 Adhere to the safety data sheets provided by the manufacturers of the materials and
media, in particular for hazardous substances:
– Comply with the hazard and disposal instructions.
– Set out protective measures and compile operating instructions for hazardous
substances.
– This also applies to hazardous substances that may develop during work processes.
Refer to the order confirmation/parts list from AWH for the materials used in the device.

When using the device, it is necessary to distinguish between the following operating states.
Operating State –Cleaning Process (cleaning > cleaning medium is sprayed and cleaning head rotates)
In this case, flammable gases, vapors, mists or combustible dust may already be present in the
container or are only added by the intended cleaning process in the form of sprayed fluid (aerosol).
Flammable vapors and mists must be expected as soon as flammable fluids with a flash point of 15 K
above the cleaning medium temperature are sprayed, including those permitted in accordance with
Section 3.4 Cleaning Media. For this reason, both the conditions in the container and the type and
temperature of the cleaning medium must be taken into account when defining the following three
process conditions:
A) During cleaning, no potentially explosive mixture is present, nor is it possible for one to develop from
the cleaning medium. (Potentially explosive mixtures consist of flammable gases, vapors, mists or
stirred-up combustible dust and air or another oxidizing agent that reacts to a self-propagating
flame when an ignition source becomes active, generally causing an abrupt increase in temperature
and pressure).
 Pressure in the container: 0 to 0.5 bar (0 to 7.25 psig)
 Temperature of the cleaning medium: +5 °C to +95 °C
 Ambient temperature in the container to be cleaned: +5 °C to +95 °C
 Ambient temperature outside the container to be cleaned: +5 °C to +40 °C
B) There is a potentially explosive atmosphere in the container during cleaning (ATEX conditions).
(A potentially explosive atmosphere is a potentially explosive mixture with air as an oxidizing agent
under atmospheric conditions (ambient temperature of -20 °C to +60 °C and absolute pressure of
0.8 bar a to 1.1 bar a, that is already present before the use of the device, or that develops when
spraying a cleaning medium during the cleaning process)
 Pressure in the container: 0 to 0.1 bar (0 to 1.45 psig)
 Temperature of the NON-flammable cleaning medium: +5 °C to +60 °C
 Temperature of the flammable cleaning medium: +5 °C to flash point T flash point -15 °C
(max. +60 °C)
 Ambient temperature in the container to be cleaned: +5 °C to +60 °C
 Ambient temperature outside the container to be cleaned: +5 °C to +40 °C
C) A potentially explosive mixture is present during cleaning, but there is no potentially explosive
atmosphere.
Cleaning is PROHIBITED! If necessary, the process conditions must be changed before using the
device so that process conditions exist in accordance with A) or B).
For processes that are outside atmospheric conditions, the operating company must make a
differentiated assessment of the effects.
The necessary safety-related parameters must be determined and an additional risk assessment
must be created for explosion hazards in order to separately verify the suitability of the device used.
The cleaning process for the devices is prohibited in operating conditions that lead to potentially
explosive mixtures outside atmospheric conditions (temperature between -20 °C and +60 °C and
absolute pressures of 0.8 bar a to 1.1 bar a) in the container to be cleaned or in the presence of
oxidizing agents other than air.
