6.Pour 2 quarts (2 L) of hot water into the water pan and turn the cycle control to “CLEAN.” This step warms up the system and allows the cleaning solution to be more effective. Allow to circulate 5 minutes. Turn switch to “OFF’ and drain.
Prepare the cleaning solution by thoroughly mixing 6 oz. (170 gm) of powdered citric acid or phosphoric acid into 2 quarts (2 L) of hot water. Commer- cial ice machine cleaners are also available in liquid form and should be mixed according to instructions on the label.
7.Pour cleaning solution into water pan and turn switch to “CLEAN.” If solution foams while pouring, stop until foaming sub- sides, then add balance of solution. Allow solution to circulate until scale has dissolved. The circulating solution may not contact scale on the side flanges of the freezing plate. To remove this scale, wear rubber gloves and use a stainless steel sponge or pad dipped in cleaning solution to scrub the side flanges until scale is removed. Generally scale will be dissolved in 15 to 30 minutes. Severe scale formation may require repeating the cleaning process with a fresh quantity of solution if the scale has not dissolved after 30 minutes.
8.Turn switch to “OFF’ and drain.
9.Follow cleaning with two fresh water rinses, circulating each rinse for 5 minutes, and drain.
10.This completes the “inplace” cleaning and sanitizing of the water system and freezing plate. Other interior components must also be cleaned and sanitized.
