Operation 3. Operation 3.1. Initial Setup 3.1.1. Auto Fill Timer/ Auto Re- Fill Timer Both timers for the CMA-44 are set at the factory. When the power button is activated, the machine should fill until it begins to overflow into the scrap tray, at which point it should stop filling. If necessary, adjust the time set on the Auto Fill Timer to allow an appropriate amount of water flow to properly fill the Dishmachine. After the auto-fill is timed out the refill system is energized w

Operation pressure regulator is adjusted to 20-PSI. This allows 0.8 (CMA-44L), or 0.94 (CMA-44H) 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. At this level, maximum shelf life is available. Inside the control box is a labeled power block for the sanitizer and rinse aid, which is powered
