This procedure should only be carried out by persons trained by Marco
Beverage Systems or their approved distributors.
The operation of higienization/sterilization has to be carried out every time the
refrigerator is installed and:
- every 6 months when it is used.
- every time the water filter is changed.
- after an inoperative period of one or more weeks.
If the refrigerator is installed in Hospitals, Schools, Elderly
people’s homes, or
Clinics, it is recommended to sterilize it every 3 months.
Use a suitable product that is both a detergent and a sanitizer, to be mixed
with water in the proportions recommended by the manufacturer. Marco
Beverage Systems recommend Bioguard Internal Water Cooler Sanitiser. We
suggest to change the product type on a regular basis too, to prevent resistant
bacteria from becoming established.
Never exceed the contact times and maximum dosage concentrations
recommended by the manufacturer. Once the sanitizing fluid has flowed
through and cleaned the lines, they must be thoroughly rinsed with mains
water until all the sanitizer has been completely eliminated. Check the pH of
the outlet water is the same as the pH of the inlet water (use litmus paper or a
pH meter).
4.3.4 SANITIZING:
CAUTION
Before carrying out the following operations, carefully read the instructions given
by the sanitization product manufacturer and make sure all personal protective
equipment (gloves, masks, etc.) is worn correctly. The sanitization of the product
lines must only be carried out by specialized technical service personnel. During the
sanitization operations, attach a warning sign to the tower concerned, to inform
any other personnel that this operation is in progress, and that it is forbidden to
dispense beverages.
