all components with a clean 

wash cloth in the hot water 

and sanitizer solution. Use 

a clean, soft bristle brush 

as needed for the smaller 

components and tight ar-

eas. Do not immerse hop-

per lids. Use a commercial 

sanitizer that has 100 ppm 

of available chlorine with 

a concentration level of at 

least 3% available chlorine 

(KAY-5 Sanitizer). Follow the 

sanitizer’s mixing instruc-

tions to ensure 100 ppm of

NOTE – Although most parts are dishwasher safe, they may be affected by the chemicals in some commercial sanitizing agents. Do not 

place the hopper nor hopper lids in a dishwasher. Rinse thoroughly before assembly.
