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. 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 when the final rinse trip switch is activated. The detergent power block is also labeled and provides power when the conveyor and pump motors are operational.

3.3.Regular Service and Maintenance Checklist

1.Upon entering the facility, make a preliminary check of the flatware and glasses, especially the stemware. This will give you a quick indication of how the machine is functioning.

2.With the circuit breaker providing power to the machine turned off, open the door and check the interior condition of the machine.

a.The stainless steel on the inside of the machine should be clean and shiny, no dull look or buildup of white lime scale.

b.Check the condition of the strainer trays for excessive garbage. The machine operator should be cleaning the machine—explain proper cleaning procedures.

c.Open the drains and check to make sure they are all working properly.

3.Once the machine has drained, remove both end curtains and remove all the strainer trays from the machine.

a.Check all spray arms and jets - clean as necessary. Explain cleaning procedures to the operators.

b.Check the drain openings making sure they are free and clear of debris.

4.Close the drains, turn the power on and fill the machine.

a.Check the fill vacuum breaker for leaks.

b.This is the time to check the water hardness. Check the water at the fill while it is coming into the machine.

c.Using a rod or something long to avoid contact with the rinse water, actuate the final rinse trip switch and observe the spray pattern on the final rinse jets. (It is easier to see while the pressure is lower.) If you have any clogged rinse jets, clean them using a paper clip or similar wire.

5.Verify that the heater is working. If the temperature is below 140° check the thermostat setting. Also, check that the heater contactor has activated (toggle the heater switch and listen for the contactor pulling in and dropping out). Check that the float switch is working properly (this will also cause the heater contactor to pull in and drop out when actuated).
