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.
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.
Draining using compressed air
If the machine is drained using compressed air, then the compressed air pressure must not cause the machine to rotate.
Draining should always be done inside the tank.
See paragraph 4.4 Specific conditions for safe use in accordance with ATEX/IECEx certification (page 16).
Steam cleaning
If stream cleaning is done through the machine, the steam pressure must not cause the machine to rotate.
See paragraph 4.4 Specific conditions for safe use in accordance with ATEX/IECEx certification (page 16).
Temperature
The machine is designed to operate with cleaning media at temperatures up to 95°C (203°F). However, it withstands
temperatures up to 140°C (284°F) inside the tank.
See paragraph 4.4 Specific conditions for safe use in accordance with ATEX/IECEx certification (page 16).
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
flush with water after use, as this might create hydrochloric acid.
