Operating Instructions 
 
1. Scraping and Pre-rinse
 
Remove remaining food from utensils. Scrape by hand or by using a cleaning tool such as a sponge or 
rubber spatula. For protection of the hands, wear gloves. 
 
Use a pre-rinse hose for wet scraping to remove small particles of soil not removed by the hand scraping 
operation. The purpose is to keep excessive garbage from going into the dishwashing machine. 
 
HAND SCRAPING
WET SCRAPING
DON’T PILE DISHES!!
 
 
 For flatware, it is recommended that they be pre-soaked in a deep pan, generally a bus pan, using a 
presoak detergent. This will prevent drying or adhering of soil on flatware and reduce tarnishing. A 
presoak detergent is especially useful for the removal of protein soil such as egg, syrup, etc. Allot 
approximately 30 minutes for presoaking if possible for better results. 
 
2. Sorting and Racking
Properly placing the utensils in the rack is one of the most important jobs the operator must perform. 
Sort out different utensils, separating dishes, bowls, cups, glassware and flatware. 
3. Racking dishes
PROPER RACKING
 
Note in the illustration that the 
plates are racked without 
overlapping and that the sprays 
from the top spray arm will strike 
the food contact surfaces of the 
dishes (face of the dishes) 
 
Rack all the same sized plates together row by row. The dish rack will hold them just right for proper 
washing. The entire surface of the soiled dish must be covered by the spray arm to provide sufficient 
scrubbing action when the detergent solution is being sprayed on that dish. 
 
 Stacking dishes will not save time because the dishes will not be cleaned during the wash cycle and will 
require sorting and rewashing.
