IMPORTANT! Before replacing the membrane, verify the compliance of the Consumable storage requirements
described in Section 4.4 in the membrane to be installed or call your supplier for the acquisition of a new membrane.

11.4 Tank cleaning and disinfection

The tank must be emptied, cleaned and disinfected:
-
At least once a year (recommended: at least 2 times a year)

After prolonged stops.
Cleaning the tank eliminates the contamination attached to the tank walls. It is recommended to clean the tank with a jet
of water under pressure or by rubbing the tank walls.
A small dose of neutral detergent can be used during the cleaning. After cleaning, the detergent must be completely
removed. To remove it, thoroughly rinse the tank with water.
After cleaning and disinfecting the tank, thoroughly rinse the tank with tap water, and use purified water for a final rinse.
