Installation and Normal Operation
(continued)
It is recommended to install a filter with mesh size 250 µm (0.01”) in the supply line in order to avoid
particles, scale etc. from clogging the inside of the cleaner. It is essential to avoid fine solid particles,
such as fine sand, in the cleaning fluid as they will increase wear considerably, and may cause slower
rotation speed or stoppage. This is particular important in case of recirculation.
Before installation, all supply lines and valves must be thoroughly flushed to remove remains of
welding electrodes, grinding dust, scale and other foreign matter.
During handling and installation handle the machine with care in order not to damage the fine surface
of the machine.
The Toftejorg SaniMidget Retractor machine has been tested at the factory before shipping, in
accordance with the Test Specifications .
Note: The machine shall be installed in accordance with national regulations for safety and other
relevant regulations and standards. In EU-countries the complete system must fulfil the EU-Machine
Directive and depending of application, the EU-Pressure Equipment Directive, the EU-ATEX Directive
and other relevant Directives.
Safety Precautions
The Toftejorg SaniMidget Retractor is intended for use inside a tank only, and must not be operated in
open air or when the tank is open.
Warning: Precautions shall be made to prevent starting of the cleaning operation, while personnel
are inside the tank or otherwise can be hit by jets from the cleaner head
Warning: If the machine is used in potential explosive atmospheres, tapes or joint sealing
compounds, which are electrical insulators, must not be used on joints, if this may
violate the grounding of the machine to the tank. Resistance between nozzles and tank
must not exceed 20.000
Ω
. The intended installation with standard clamp connections
will ensure this. In addition, connecting pipe work, must be electrically conductive and
earthed to the tank structure.
This is essential to avoid the build-up of static electricity on the nozzles and the
machine. For further information see CENELEC R044-001 Safety of Machinery,
guidance and recommendations for the avoidance of hazards due to static electricity.
Electrical equipment such as magnetic valves and electric actuators must not be installed in Ex-zones
without type approval and marking, corresponding to the EX-class in question. Magnetic cylinder
sensors shall be EX-approved.
