13. CLEANING

13.1 INTERNAL

ATTENTION

Do not scrape the ice from the walls with pointed tools, the surfaces will be ruined. Do no use high pressure appliances (e.g. steam generators).

1. Remove the product contained in the refrigerated compartment and place it immediately in a special refrigerator conservative to ensure proper storage.

2. Turn off the equipment.

3. Remove accessories manually removable (e.g.. Sliding, grills, ice cream containers, etc).

4. Wait at least 4 to 6 hours, until the ice on the evaporator has melted completely, before proceeding with cleaning operations. We suggest in this regard, you wait for the next day to make sure that the defrosting is completely done. Do not use mechanical devices or other means to accelerate the defrosting process, other than those recommended by the manufacturer.

5. Remove (if present) the drain plug of the tank bottom to drain the defrost water.

6. Clean the side panels and the bottom of the tank using a mild detergent, warm water and a cloth or sponge. Do not use sharp tools. Rinse thoroughly and dry with an absorbent cloth.

7. If the equipment was joined to a ﬂ oor drain, slide lukewarm water containing a sanitizing solution suited to the speciﬁ c application. The amount of solution to be used should be such as to ensure a perfect removal of any residual product and proper sanitation along the entire path of the drainage.

8. If the equipment is not joined to a ﬂ oor drain, follow the procedure referred to above. The rinse water collected in the tank will be positioned inside the base of the apparatus. Clean and disinfect the collection tray.

9. Fit the accessories that were removed (step 3).
