The device was developed, engineered and built exclusively for industrial and commercial use (food,
chemical and pharmaceutical industries and low-germ processes). It must not be used for private
purposes.
The device is constructed so that it can be operated safely within the specified technical parameters
(see
Section 3.3 Technical Data ).
The TANKO-RT and TANKO-RTS retractor system is suitable for use in Zone 0 or Zone 20 (in the
container) and Zone 1 or Zone 21 (outside the container / actuator unit) explosive atmospheres.
Please note the additional information on the type plate for the Ex labeling (see Section 2.5.3 Identification
for Explosion Protection ).
The owner must always check whether the device is suitable for his application.
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 disabled.
Locations for containers in which the device is to be installed are usually closed rooms. If the set-up
is different, the owner is responsible for ensuring the device is protected against harmful weather
and environmental influences in compliance with the specified operational limits / conditions
(see
Section 3.3 Technical Data ).
