gned for commercial dishwashers available for this pur-
pose, please consult your detergent supplier.

corrosion. Product must be kept free of limescale for
proper operation. Please contact your chemical sup-
plier. Only use approved non-chlorinated, non-foa-
ming commercial dishwasher chemicals. Always
