Installation and Normal Operation
General Installation Instructions
The tank cleaning machine should be installed in vertical position (upright or upside down). It is
recommended to install a filter in the supply line in order to avoid large particles, scale etc.- to clog
inside the machine. It is essential to
avoid fine solid particles, such as fine sand, in cleaning fluid as
they will increase wear considerably.
In general a filter with 3 mm holes is recommended in the supply line. In case of fine solid particles
below 500
μ
m in the cleaning fluid, choose filter size accordingly.
It is recommended that the fluid valve fitted is of a type that
prevents hydraulic shocks, which may
cause severe damage to the entire installation.
Before connecting the machine onto the system,
all supply lines and valves should be flushed in order
to remove foreign particles.
The machine should be screwed tightly onto its supporting supply line using a 36 mm flat jawed
spanner (tool No. TE81B040) and the flats machined on the inlet Cone.
For devices with tapered thread connections to the down pipe, it is recommended that you secure the
connection in a manner appropriate for the application. Subject to the intended use environment and
any inhouse user requirements or policies, an adhesive such as Loctite No. 243 or equivalent could be
used. Other methods could be acceptable and subject to customer preference.
Warning:
If the machine is used in potential explosive atmospheres, tapes or joint sealing
compounds which are electrical insulators must not be used on threads or joints, unless
an electrical connection is otherwise established to ensure an effective earthing. In
addition, connecting pipe work, must be electrically conductive and earthed to the tank
structure. The resistance between the nozzles and the tank structure should not exceed
20,000 Ohm. This is essential to avoid the build-up of static electricity on the machine.
For further information see CENELEC R044-001 Safety of Machinery, guidance and
recommendations for the avoidance of hazards due to static electricity.
Note : The machine shall be installed in accordance with national regulations for safety and other
relevant regulations and standards.
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 nozzles.
In EU-countries the complete system must fulfil the EU-machine directive and shall be CE-marked.
The machine has been tested at the factory before shipping. Check that the machine is in operating
condition by inserting Screwdriver in top of Turbine shaft and easily turn Turbine shaft anti-clockwise. If
any resistance is recognised, the machine should be disassembled in order to localise the cause.
