When using the device, it is necessary to distinguish between the following operating states.
Operating state - cleaning process (cleaning > cleaning medium is sprayed and spray head rotates)
In this case, ignitable gases, steams, mists or flammable dusts may already be present in the container
or are only added by the intended cleaning process in the form of sprayed fluid (aerosol).
Ignitable steams and mists must be expected as soon as flammable fluids with a flash point of 15 K
over 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 determining the following three
process conditions:
A) During cleaning, no explosive mixture is present, nor is it possible for one to arise from the cleaning
medium. (Explosive mixtures consist of ignitable gases, steams, mists or stirred up flammable dust
in the air or another oxidizing agent that reacts to a self-propagating flame when an ignition source
becomes active, generally causing a sudden increase in temperature and pressure).
Pressure in the container: 0 to 0.5 bar (0 to 7.25 psi g)
Temperature of the cleaning medium: +5°C to +180°C
Ambient temperature in the container to be cleaned: +5°C to +180°C
B) An explosive atmosphere (ATEX conditions) is present during cleaning.
(An explosive atmosphere is a 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 arises during spraying of a cleaning medium
during the cleaning process)
Pressure in the container: 0 to 0.1 bar (0 to 1.45 psi g)
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
C) An explosive mixture is present during cleaning, but there is no explosive atmosphere.
Cleaning is PROHIBITED! If necessary, the process conditions must be changed before use of 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 demonstrate the suitability of the device used.
The cleaning process with the tank cleaning devices TANKO-EX-S and TANKO-EX-RB is prohibited in
operating conditions that lead to explosive mixtures outside atmospheric conditions (outside

Pressure in the container: Depending on the permissible maximum pressure of the container and
the attached fittings including media supply. The media supply must be closed tightly, the cleaning
device does not have its own shut-off device.
Ambient temperature in the container to be cleaned: -20°C to 180°C
The device was developed, engineered and built exclusively for industrial and commercial use. It must
not be used for private use.
Operation may also be carried out if an explosive dust or gas atmosphere is present, or can develop,
inside the tank that is to be cleaned.
The TANKO-EX-S or TANKO-EX-RB is suitable for use in an explosive Zone 0 or Zone 20 atmosphere.
Please note the additional information on the type plate for the Ex labeling (see Section 2.5.3 Labeling
for Explosion Protection).
In all cases, operating company must check whether the device is suitable for its application.
NOTE ON EXPLOSION PROTECTION
The area of application of the device must always be adjusted to the relevant operating
conditions and the materials in contact with the product. These materials must be
selected to ensure that they do not react with the cleaning medium or the substances in
the container to be cleaned in any way that could impair the explosion protection.
It must be ensured that no hybrid mixtures can occur in the container or the environment
(a hybrid mixture is a mixture of air with combustible substances in different states of
aggregation - e.g. gas/steam and dust).
Non-compliance can result in the loss of explosion protection.
Locations for containers in which the device is to be installed are usually enclosed 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).

In the process, the following must always be observed:
Only operate the device when installed inside an enclosed 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, e.g. pressure and temperature
(see Section 3.3 Technical Data). If necessary, appropriate monitoring and limiting systems
(e.g. for pressure and temperature) should be implemented.
Only cleaning agents which are compatible with the materials of the device (see Section 3.4
Cleaning Media) may be used.
The preferred installation position for the device is vertical with the cleaning head pointing
downwards. Other installation positions are possible.
The device may generate vibrations when cleaning the container. Any vibrations going beyond this
must be avoided (see Section 7.4.1 Maintenance Intervals).
The device is designed for fixed pipe installation only. Installation on a hose is PROHIBITED.
Non-Intended Use
The device is NOT suitable for the following applications:
The device is NOT suitable for private use.
The device is NOT suitable for use outside of containers.
Holding the device with your hand during operation is PROHIBITED.
The device must NOT be immersed in the product of the production process (NOT even partially).
This could cause the product to enter into the device. The spray holes may become blocked. The free
movement of the actuator may be obstructed.
The device must NOT by operated with gases (e.g. air) over a long period, as the cleaning medium is
used for lubrication of the bearings.
The device is intended exclusively for the purpose outlined above. Any other use beyond that described
here or alteration of the device without written approval from the manufacturer is considered
IMPROPER use.
The manufacturer accepts NO liability for damage arising from such use. The operating company is
solely responsible for the risk.
The device must not be put into operation until it has been assured that all the safety devices are fully
functional and the plant in which the device is installed meets the safety requirements of all relevant
European directives (e.g. the Machinery Directive).

2.2 Spare Parts, Replacement Parts and Accessories
WARNING
Risk of damage, malfunction or complete failure of the device!
Incorrect or faulty spare/replacement parts and accessories put the functional safety
and reliability of the device at risk. This can result in failure of components or a device
malfunction, as well as material damage and consequential damage.
There is a risk of death or severe physical injury.
Use only the manufacturer's original spare parts.
We expressly draw attention to the fact that spare parts and accessories NOT supplied by AWH have
NOT been checked or approved by AWH. The installation and/or use of such products could therefore,
under certain circumstances, result in changes with negative results to the properties of the device
specified by its design and the higher-level plant.
AWH is not liable for any damage arising from the use of non-original parts or non-original accessory
parts. Standard parts can be obtained from specialist dealers.
Section 7.5.1 Spare parts includes a list of spare parts.
2.3 Duties of the Operating Company
The device is used in the commercial sector. The operating company is thus subject to the legal
obligations regarding occupational safety.

current valid versions.
Of particular importance in this connection is Directive 2009/104/EC on the minimum specifications
for safety and health protection of employees using work equipment in their work.
NOTE ON EXPLOSION PROTECTION
For applications in the presence of explosive atmospheres, the Directive (1999/92/EC
with Annexes I and II) on minimum requirements for improving the safety and health
protection of workers potentially at risk from explosive atmospheres also applies.
If this is not observed, the explosion protection could be disabled.
As a basic rule, in Germany the Industrial Safety Regulation (BetrSichV) must be observed.
In other countries, the respective national guidelines, statutes and country-specific regulations
regarding occupational safety and accident prevention must be complied with.
