OPERATION

OPERATION SUMMARY

Action Result

1. Push the On/Off power switch “UP” to the ON position. Dishwasher fills automatically.

2. Wait approximately 10 minutes for the wash tank heater to heat the water. Then, check the reading on the wash water temperature gauge.

3. Prescrap and load the ware into the dishrack.

4. Open the doors. Insert a dishrack of soiled ware. Fully close the doors.

Opening the doors anytime during the automatic cycle stops the dishwasher. Closing the doors will resume the cycle where it left off.

5. Check the final rinse temperature gauge reading during the 14 second final rinse cycle.

1. The power indicator light illuminates. The wash tank heater and the booster tank heater begin to heat.

2. The wash water temperature gauge should indicate a minimum of 150°F/66°C for MH60,MH-6N and 120°F/60°C for MH-6L.

3. Ware should be placed edgewise in the peg rack. Cups and bowls should be placed upside down in the flat rack. Silverware should be spread evenly in a single layer in the flat rack.

4. In-cycle light illuminates as the dishwasher begins a 60 second automatic cycle. The cycle times are listed below:

Wash = 45 seconds Dwell = 1 second

Final rinse = 14 seconds

5. The final rinse temperature gauge should indicate a minimum of 180°F/82°C for MH-60/ 6N. The optimum final rinse temperature range is between 180-195°F/82-90°C for MH60/6N. MH-6L optimum is 140°F/60°C.

6. Check the incoming water pressure during the 10 second final rinse cycle.

7. The 60 second automatic cycle ends.

8. Open the doors. Remove the clean rack. Insert another rack of soiled ware. Fully close the doors.

9. Turn power OFF at the dishwasher. Remove the drain-overflow assembly. Clean the scrap screens. Clean the dishwasher after each meal period or every two hours of operation.

6. The water pressure gauge should indicate a flowing pressure of 20-22 PSI/138-151.8 kPa. A pressure reducing valve (PRV) is required if flow pressure exceeds 20-22 PSI/138-151.8 kPa.

7. The in-cycle light goes out.

8. The 60 second automatic cycle begins again.

9. Dishwasher wash tank drains completely. Periodic cleaning reduces detergent consumption and improves washing results.
