EACH IS CORROSIVE It can and will damage components of the machine causing premature wear and metal corrosion GENERALPURPOSECLEANERS General purpose cleaners do not have the ability to remove milkstone Milkstone will become a problem if not remedied with additional products and procedures THEUSE OF CHLORINE TEST STRIPS Test strips are used to determine concentrations of active chlorine in sanitizing solutions To use the strips tear off a small portion and submerge it into the sanitizing solution Then compare the color change to the color key on the side of the test strip dispenser to determine the approximate chlorine concentration The ideal concentration of chlorine needs to be 100 ppm as stated by the FDA NOTE Follow the directions on the container for proper concentration There are two main factors that contribute to falling chlorine concentrations in a sanitizing solution 1 PRODUCT USE As the chlorine in the solution is being used chlorine concentrations fall 2 As time passes small amounts of chlorine evaporate from the solution Thatis why you can smell it Sanitizing solutions should notbe allowed to fall below 100 ppm chlorine New solutions should be mixed once old solutions become ineffective 3 4 DISASSEMBLY OF FREEZER PARTS Moving machinery can grab mangle and dis member Place the ON OFF toggle switch in the OFF position before disassembling for cleaning or servi
