Operation The sanitizing pump operates when the fresh water enters the machine during final rinse. The water is treated at 50 PPM (parts per million). The pressure regulator is adjusted to 20-PSI. This allows 0.8 (CMA-66L), or 0.94 (CMA-66H) gallons of water to enter the machine each time a rack is washed. It is recommended that the 5-1/2% chemical solution be standardized to allow uniform dispensing of the sanitizing solution into the flow of rinse water as the machine operates.
