1. Introduction
The Scanjet BIO 25 is a highly versatile machine for use in hygienic applications as
well as other industrial applications. Its unique design makes it easy to install, use
and maintain as well as reduces the pressure drop through the machine.
The BIO 25 is per standard delivered with two or four nozzles in different nozzle
sizes, between Ø5mm and Ø18mm.
A special nozzle configuration with two extra nozzles cleaning the outside of the
machine provides unmatched self cleaning capability.
This manual has been prepared as a guide for persons who will be operating and
maintaining the tank cleaning machine. The key for long machine life will always
be carefully planned maintenance. If this is properly executed the Scanjet BIO 25
till keep servicing you for years.

2. Safety Instructions
• If the machine is used in potentially explosive atmospheres then 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 grounding. In addition, connection pipe work must be
electrically conductive and grounded to the tank structure. The resistance
between the nozzle and the tank structure should not exceed 20 000
Ohm. This is important in order to avoid any build up of static electricity
in the machine. For further information see CENELEC R044-001 Safety of
Machinery, guidance and recommendations for the avoidance of hazards
due to static electricity.
• When the equipment is operating in potentially explosive atmospheres,
measures have to be taken to verify that the tank is inert at all times during
cleaning operation. This is to avoid sparks and possible explosions since fluids
moving at high velocities through air causes electrostatic build up in the
media. As an extra precaution the cleaning media could be made conductive.
• The machine should be installed in accordance with national regulations for
safety and other relevant regulations and standards.
• Precautions should be made to prevent starting of the tank cleaning
operation, while personnel are inside the tank or otherwise can be hit by
jets by the jets.
• In EU-countries the complete system have to comply with EU-machine
directive and should be CE-marked. In North America consult Underwriters
Laboratory for any specific regulatory needs relative to the entire CIP (Clean
In Place) System.
• Ear protection should always be used when operating machine.
• Be careful not to drop the tank cleaning machine/equipment when lifting
and/or carrying. Dropping the machine could cause serious injuries. Never
stand underneath the machine during mounting or operation.
• The equipment may only be used for tank cleaning operations as described
in this manual.
• The equipment has not been assessed as a safety related device as referred
to in directive 94/9EC Annex II, clause 1.5
Always follow these instructions before taking the BIO 25 into service!

3. General Description
The Scanjet Bio 25 is a media driven and lubricated tank cleaning machine. No
lubrication substances such as oil, grease etc. are used. All materials in contact
with the machine meet the general standards for hygienic process. Ceramic
and tungsten bearings are standard for an extra long service life. The unique
design of the Scanjet BIO 25 makes it completely self-cleaning and self-cleaning.
There are no interior pockets where water and dirt can accumulate, making this
machine one of the best choices for hygenic applications.
Functional Principle
When cleaning media enters the machine it first passes through a turbine and a
worm gearbox, then a nozzle housing leading it out through the nozzles and into
the tank. The turbines rotation drives the worm gearbox, making the machine
rotate around its own axle and at the same time, the nozzle housing is forced to
rotate clockwise.
A combined motion of the machines body and nozzle housing creates a criss-
cross cleaning pattern inside the tank. After 6 1/8 rotation of the nozzle housing,
a first course pattern has been created. This process is repeated 8 times, each
time indexed from each other until a full cleaning pattern has been created.
When this is finalized, after 47 rotations of the machine body, or 49 rotations of
the nozzle housing, the first cycle will be repeated.
Cleaning of tanks is a process depending on a number of factors; soilage, distance
between nozzles and tank walls, cleaning media, temperature etc. All of these
factors need to be considered before a proper cleaning can be accomplished.
The rotation speed of the machine idepends on flow rate through the machine.
Higher flow rate makes the turbine spin faster and because of this the machine is
equipped with different turbines according to nozzle size and intended operating
parameters.

5. Performance Data
Under performance data Scanjet presents Effective Jet Length.
Effective Jet Length is defined as the distance between the nozzle and the tank
surface where the jet achieves 250 mm water column (50lbs/sqr.ft) impact force
at tank surface. The Effective Jet Length is measured at horizontal and static
conditions.
The Jet Length is affected by a lot of different factors such as rotation speed of
the machine (velocity of the jet at the tank surface), temperature of the cleaning
media, cleaning agent used and so on.
The vertical jet length can be estimated to be approximately 1/3 less than the
horizontal jet length.
The following graphs show the flow, effective jet length (radius) and complete
cleaning time for each combination of inlet pressure and nozzle diameter. Other
nozzle diameters and maximum jet lengths are available upon request.
Please note that when equipped with non-return check valve, the flow will
decrease an estimated 10%.
Flow vs Pressure
The inlet pressure has been measured at the machine inlet. In order to achieve
the same performance as indicated in these curves the pressure drop in the
supply line must be taken into consideration.

6. Installation Instructions
General Installation Instructions: The Scanjet BIO 25 cleaning machine is
designed to be installed in a vertical upright or inverted position, however, the
machien may operate horizontally or in any other desired position.
Filtration: It is recommended to install a 100 micron filter in the supply line in
order to avoid large particles lodging inside the machine. All supply lines should
be flushed to remove dirt and particles before connecting the machine to the
system.
Cleaning Media: Only media compatible with the materials listed on the
reference list of parts for your model should be used. See “4. Technical Data”
on page 7.
After Use Cleaning: Depending on the type of cleaning that has been
performed and the type of cleaning media used, a procedure for after use
flushing of the cleaning system should be developed for your application. In
general, a fresh water flush is recommended after each cleaning process.
Pressure: Hydraulic shocks may damage the system. In order to avoid shocks
increase pressure gradually from 0 to maximum operating pressure over 5-7
seconds. Do not exceed 14 Bar (200 PSI) inlet pressure! Higher pressure in
combination with higher flow rates will increase consumption of wear parts and
could result in major leakage.
Warning! If the machine is used in potentially explosive
atmospheres then 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
grounding. In addition, connection pipe work must be electrically
conductive and grounded to the tank structure. This is important in
order to avoid any build up of static electricity in the machine.
NOTE! The machine is only self-draining if installed in a vertical
position, upright or inverted.

#Bio25 11 – 140813 Page 13 of 40
6.1. Connecting to Supply Line
Never attach the Scanjet BIO 25 by grabbing the nozzle housing! Always use
proper tools, and turn on the threaded connection as shown in the picture below.
When threading the inlet connection of the tank cleaning machine to the
cleaning media connection, Scanjet recommends that Food Grade Teflon tape
or any other appropriate food grade anti-seizing compound is used to avoid
metal galling. (Galling means that threads clamp together and cannot easily be
loosened.)
Following anti-seize compounds is recommended for use with food
industry, “FDA approved”

7. Maintenance
7.1. Preventive maintenance
In order to keep your Scanjet tank cleaning machine servicing you as an efficient
tool in your tank cleaning operations, it is essential to care for maintenance.
Following a simple preventive maintenance program will keep your tank cleaning
machine in good condition and the machine will maintain its high performance.
The following recommended, preventive maintenance program is based on tank
cleaning machines working in average conditions. However, a cleaning machine,
which has a rough and dirty job to do, will need more frequent attention than
one working in ideal conditions. It is recommended that the maintenance
program is adjusted to suit such a situation.
Only use proper tools when servicing the machine; see chapter “16. Tool Kit” for
Scanjet standard tool kit. Never use excessive force or hammer components
together or apart. Always follow all assembly/disassembly steps in the order
described in this manual. Never assemble components without previous cleaning;
this is especially important at all mating surfaces. Work only in a clear well lighted
working area.
Good maintenance is careful and regular attention!
NOTE! Timely replacement of bearings will prevent costly damages to
the gears. However, all bearing bushes, made from high performance
PEEK (PolyEtherEtherKetone) material, are mounted with a press-fit
and should not be removed unless they need to be replaced.
Using any other than Scanjet original parts will invalidate
the warranty.

#Bio25 11 – 140813 Page 15 of 40
7.2. Service kits
Tank cleaning machines are mostly installed and operated in extremely rough
conditions. In order to ensure continued safe operation of the Scanjet tank
cleaning machines it is advised to follow given service instructions.
Scanjet has identified components which should been checked at regular
intervals and replaced if necessary, because of wear or damage. This is important
in order to avoid unplanned stops or breakdowns and to assure safe, smooth
and trouble free operation of the tank cleaning machines. The components that
may be subject to wear and need replacement have been included in service kits,
naturally optimized for each specific model and type of Scanjet tank cleaning
machine.
Service intervals are described on the following page. Note that the intervals
may be more frequesnt for machines installed in any other position than vertical,
upright or inverted.
