1. Turn the power switch ON and ensure that the water supply valve is OPEN then press the Rinse START
button. The Fill Indicator LIGHT will illuminate indicating the RINSE CYCLE has started and the Dry Acid
Dissolution Unit is in the first FILL Operation (Figure 19).
2. Once the 25-Gallon Sensor is reached, the control panel will automatically step to the first RECIRCULATE
Operation (Figure 20). With your safety glasses on, lift the Access lid and check for correct spray ball
operation. See figure 4 on page 12, for the illustration of correct or incorrect spray ball operation.
