Installation and Normal Operation

Normal Operation

Cleaning Media
Use only media compatible with Stainless Steel AISI 316L, PEEK and EPDM. Please note that PEEK
is not resistant to concentrated sulfuric acid. 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 you are in doubt, contact
your local Alfa Laval Tank Equipment sales office.
Temperature
The machine is designed to operate with cleaning media at temperatures up to 95°C (203°F). However,
it stands temperatures up to 150 °C (304 °F) inside the tank, and it is possible to steam the tank
through the machines, 121°C (250°F) at steam sterilisation.
Tanks with capacities greater than 100 m
Warning:
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.
In potentially explosive atmospheres, the temperature must not exceed the maximum
Warning:
surface temperature according to the temperature class for the combustible gas or
liquid.
Pressure
Please make sure that the connections are correctly mounted before opening of the washing valve. Put
on pressure gradually in order to avoid hydraulic shocks, which might stress mechanical parts in the
Toftejorg SaniMidget Retractor cleaner. Max. pressure is 5.0 bar.
After-Use Cleaning
After use flush the machine with fresh water. Cleaning media should never be allowed to dry or set-up
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
Hot chemicals and steam under pressure may be used for cleaning and sterilising.
Warning:
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.
