Hobart ML-130021 Dishwasher User Manual


 
– 11 –
Use only commercial-grade detergents recommended by your chemical professional. Do not use
detergents formulated for residential dishwashers.
Chemical dispensing pumps (if so equipped) are factory set to provide proper concentration of
each chemical. If adjustments are required, contact your local Hobart Service Office.
When the door is opened, the cycle light will come on during a brief reset period. When the light
goes off (approximately 9 seconds), close the door, at which time the wash cycle will begin
(indicatated by the cycle light).
When the cycle light goes off, the cycle is completed. Open the door and remove the rack of clean
dishes; after the reset period (9 seconds), the dishwasher is ready for a repeat operation.
Thermometers (Figs. 2 and 3 on page 10) are provided for convenience in checking the wash and
incoming rinse water temperatures. These temperaures should be monitored occasionally
during a cycle to make sure that the dishwasher is operating at or above the proper minimum
temperatures.
CHEMICAL DISPENSING PUMPS
The chemical sensing module will alert the operator when the supply of sanitizer has been
depleted by a flashing indicator light and a periodic audible alarm. The sanitizer MUST be
replenished immediately.
After replacing the sanitizer, the dishwasher must be operated through nine complete cycles
(without dishes) to recharge the delivery system. Use the same procedure for priming of optional
detergent and rinse pumps. For further details on the chemical sensing module and its start-up
procedures, refer to page 16.
