Installation and Normal Operation
(continued)
Normal Operation
Cleaning Media
Use only cleaning fluids compatible with Stainless Steel AISI 316/316L, PTFE, Tefzel, PVDF, Carbon,
PEEK and Teflon, TFM. Please note that PEEK is not resistant to concentrated sulfuric acid. Normal
detergents, moderate solutions of acids and alkalics will be acceptable. Aggressive chemicals,
excessive concentrations of chemicals at elevated temperatures, as well as certain hypochlorids
should be avoided. If you are in doubt, contact your local Alfa Laval Tank Equipment sales office.
After Use Cleaning
After use flush the machine with fresh water. Cleaning solutions should never be allowed to dry or set-
up in the system due to possible "salting out" or "scaling" of the cleaning ingredient. If cleaning media
contains volatile chloride solvents, it is recommended not to flush with water after use, in case this can
create hydrochloric acid.
Pressure
Avoid Hydraulic shocks. Put on pressure gradually. Do not exceed 12 bar inlet pressure.
Recommended inlet pressure appears from Technical Data (page 8-9). High pressure in combination
with high flow rate will increase consumption of wear parts.
ATEX
Warning:
If stream cleaning is done through the machine, the steam pressure must not cause
the machine to rotate.
ATEX
Warning:
If the machine is drained using compressed air, then the compressed air pressure
must not cause the machine to rotate.
