4 Installation
4.1 General Description
The Alfa Laval Toftejorg SaniMxxxx SB series are tank cleaning machines intended for industrial use in closed tanks, vessels
and containers under typical CIP procedures. They have a broad range of application areas within pharmaceutical, food,
dairy and chemical industries.
The Alfa Laval Toftejorg SaniMxxxx SB is a sanitary cleaning device of the rotating fan spray type for permanent installation
that provides either a 270° upward cleaning pattern or a 360° cleaning pattern. The machine is designed to be completely
self-cleaning as proven by the EHEDG test method. If Installed according to the description on page 11, the Alfa Laval Toftejorg
SaniMxxxx SB is completely self-draining in the shown position and completely inspectable. All product contact surfaces are
AISI 316L stainless steel or polymer material that conforms to FDA21CFR§177 and EU 10/2011. For the Alfa Laval Toftejorg
SaniMxxxx SB plastic material that meets the requirements of 3-A Sanitary Standard 20-25 is used. For the Alfa Laval Toftejorg
SaniMidget SB/UltraPure a USP Class VI plastic material is used.
The unique design is totally free of weldings, threads, screws and press-fits to facilitate self-cleanability. The cleaning device
is lubricated by the cleaning media. No oil, grease or other lubricants are used.
The Alfa Laval Toftejorg SaniMxxxx SB is designed for use in pharmaceutical, biotechnological, food and dairy processing
applications. It may be used in reactors, mixing/processing tanks, spray dryers and other process equipment with a volume
from 7.5-220 m³ (2-60,000 US gallons)*. For larger volumes, multiple Alfa Laval Toftejorg SaniMxxxx SB’s may be applied.
* to comply with EU 10/2011 the minimum batch size should be considered. For more information see Declaration of
EU 10/2011 conformance page 34.
Application assistance and recommendations for optimal position is available.
4.2 Functioning
The flow of cleaning media comes through the down-pipe, flushes the connector and exists through the bearing surfaces, slots
and leakage passages. This causes the head of the Alfa Laval Toftejorg SaniMxxxx SB to rotate, with fans of water laid out in a
swirling pattern on the entire perimeter exposed to the spray pattern. This generates a vibrating impact in the impact pattern
and a dynamic cascading flow that covers all internal surfaces of the tank, vessel or reactor.
The Alfa Laval Toftejorg SaniMxxxx SB is (as the rest of the UltraPure and Sani portfolio) designed according to GMP – compliant
materials, self-cleaning and drainable. The self-cleaning featureofthedeviceisduetotheuniquedesignthatincludescleaning
of the downpipe. The device is designed with no hindrance to gravity draining. The patented easy assembly and disassembly of
the device allows for only one clip to be used and without any press fits. Upon removing the clip this ensures that no parts can
fall into the tank (the Alfa Laval Toftejorg SaniMxxxx SB must be held in one hand and the clip in the other hand).

4.3 General Installation Instructions
It is recommended to install a filter with mesh size 250 µm (0.01”) in the supply line to avoid particles, scale etc. from clogging
the inside of the cleaner. However, particles up to 0.8 mm can pass the cleaning slots in the rotor.
Before installation, all supply lines and valves must be thoroughly flushed to remove remains from welding, 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.
Randomly selected Alfa Laval Toftejorg SaniMxxxx SB machines are tested at the factory before shipping, in accordance
with “Test Requirements for SaniMxxxx SB”.
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-Machinery Directive and depending of application, the
EU-Pressure Equipment Directive, the EU-ATEX Directive and other relevant Directives.

Important
information:
Recommended installation position:
The Rotary Spray Head tank cleaning machine should be installed in vertical position (upright or upside
down). If the machine is installed in any angle to vertical, the life time may vary. If installing at an angle to
vertical, ensure that the clip cannot fall out by gravity. To maintain drainability, the device should not be
tilted more than 25° to vertical.
ATEX 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 til IEC/TS 60079-32-1:2013, guidance and recommendations for the avoidance of
hazards due to static electricity.

5Operation
5.1 Normal Operation
Cleaning Media
Use only media compatible with Stainless Steel AISI 316L and PEEK. Normal detergents, moderate solutions of acids and
alkalics are acceptable. Aggressive chemicals, excessive concentrations of chemicals at elevated temperatures, as well as
certain solvents hydrochlorides should be avoided. If in doubt, contact your local Alfa Laval sales office.
Note: PEEK is not resistant to concentrated sulphuric acid.
Temperature:
The machine is designed to operate with cleaning media at temperatures up to 95°C (203°F). However, it withstands
temperatures up to 150°C (304°F) inside the tank.
ATEX Warning: Atmosphere/surface temperature:
In potentially explosive atmospheres, the temperature must not exceed the maximum surface temperature
according to the temperature class for the combustible gas or liquid.
ATEX Warning: Steam cleaning
Tanks with capacities greater than 100 m3that could contain a flammable atmosphere should not be steam
cleaned, as steam issuing from a nozzle could contain charged droplets.
Tanks smaller than this may be steam cleaned providing that: the steam nozzles and other metal parts of
the system are reliably earthed and grounded to the tank structure.
Pressure:
Please make sure that the connections are correctly mounted before opening of the washing valve. Apply pressure gradually in
order to avoid hydraulic shocks, which might stress mechanical parts in the Alfa Laval Toftejorg SaniMxxxx SB cleaner. Max.
pressure difference is 4.0 bar. Ideally, use a frequency controlled pump with gradually increase of pumping speed.
ATEX Warning: Steam cleaning pressure
If stream cleaning is done through the machine, the steam pressure must not cause the machine to rotate.
ATEX Warning: Draining
If the machine is drained using compressed air, then the compressed air pressure must not cause the
machine to rotate.
After-use cleaning:
After use flush the machine with fresh water. Cleaning media should never allow to dry or settle in the system due to possible
"salting out" or "scaling" of the cleaning media. If cleaning media contains volatile chloride solvents, it is recommended not to
flushwithwa
ter after use, as this might create hydrochloric acid.
Warning: Hot chemicals and steam under pressure may be used for cleaning and sterilising. Protect against scalding
and burning. Never tamper with or try to open clamps or other connections while system is in operation.
Make sure that system is de-pressurised and drained before disassembly.

6 Maintenance
In order to keep the tank cleaning machine servicing as an efficient tool in the tank cleaning operations, it is essential to
maintain its high performance by following a simple preventive maintenance programme, which will help keep the tank cleaning
machine in good condition
Good maintenance is careful and regular attention!
6.1 Recommended Service Intervals
The design of the Alfa Laval Toftejorg SaniMxxxx SB asks for little maintenance, as there are no rotating parts in direct contact
with stationary parts. It is recommended that inspection is performed after each 500 running hours.
For continuous surveillance of the Alfa Laval Toftejorg SaniMxxxx SB, monitor and log the volumetric flow rate. If the volumetric
flow rate increases or decreases by more than 15% over time this could be a sign of wear or blockage of the flow path in certain
parts of the machine and the machine should be inspected.
A service consists of:
0. At a pressure of 0.3 bar open a hatch in the tank to verify rotation and liquid fans are emerging from all slots. ATTENTION:
Use only pure water at normal temperature for safety reasons.
If needed proceed to 1).
1. Un-install the machine (as described on the following pages).
2. Visual inspection for foreign objects. Remove any objects and clean before rotation verification.
3. Visual inspect the bearing surfaces, the holes for the clip-on connection and the width of the slots in the rotor.
4. In case of machine wear, the parts worn down are to be replaced.
5. Look for wear of the slots in the spray head. Recommendation: Replace rotor if slot width (slot at equator on rotor) exceeds
SaniMidget SB: 1.2 mm, SaniMagnum SB: 3.2 mm, SaniMega SB 4.2 mm and SaniMega SB high flow version 5.2 mm, as
throw length decreases and flow rate increases.
6. Reinstall machine.
7. Fill in the Service Log.
Lists of parts included in the machines are provided on page 28.
