11 3.3 IMPORTANT INFORMATION REGARDING CLEANING AND SANITIZING Soft serve and shake freezers require special consideration when it comes to food safety and proper cleaning and sanitizing. The following information specifically covers issues for cleaning and sanitizing frozen dessert freezers.
12 As a recommended cleaner and sanitizer for your frozen dessert machine, STERA-SHEEN has proven to be one of the best daily maintenance products for: · CLEANING – Thorough removal of all solids including butterfat and milk fat. · MILKSTONE REMOVAL – Complete removal of milkstone.

14 3.7 CLEANING THE FREEZER CAUTION Risk of Product Damage Do not use acid cleaners, strong caustic compounds or abrasive materials to clean any part of the freezer exterior or plastic parts. The exterior should be kept clean at all times to preserve the lustre of the stainless steel.
15 H. Install the spigots through the bottom of the front door ( see Figure 18). Figure 18. Front Door Assembly I . Assemble the air bleed valve O-ring onto the air bleed valves. Position the O-ring in groove close to the wide part. Apply a thin film of sanitary lubricant to the O-rings.
