SECTION III - MECHANICAL DISHWASHING PROCEDURES
MIL-HDBK-740
A. Operations. - Two and one-half to three and one-half ounces of machine dishwashing compound, FSN 7930-205-1387, should be added to each
10 gallons of wash solution. NEVER USE HAND
DISHWASHING COMPOUND, SOAP,
OR DETERGENT (HAND OR LIQUID) IN THE DISHWASHING MACHINE. When the dish-
washer is equipped the an automatic detergent dispenser, the dispenser should be set to maintain a concentration of 0.20 to 0.25 percent which is about
2.6 to 3.6 ounces per 10 gallons of wash solution. A detergent test kit, FSN 7320-144-6081, should be used to determine the specific detergent con- centration. When a dishwasher is not equipped with a detergent dispenser, the standard dishwashing compound should be added directly to the dishwasher in measured amounts to maintain a uniform concentration. For the average wash tank (single/multiple), two and one-half to three and one-half ounces
of machine dishwashing compound (1/2 of a small chinaware cup or 1/3 of a large white chinaware cup) should be added every ten minutes when automatic dispensers are not available or operable. If the dishwashing machine is equipped with a detergent concentration meter, add machine dishwashing compound, FSN 7930-205-1387, using the detergent test kit, make up the washing solution to a concentration of 0.20 percent, adjust temperature to
150°F and set needle on meter to 12 o'clock. The meter should be read after the doors have been closed and the water has been well circulated. When a rinse aid injector has been installed on a dishwasher, a rinse additive,
FSN 7930-619-9575, in one gallon bottles should be used. To figure tank
capacity when it is not given, multiply the length of the tank by the width of the tank by the height of the overflow level (in inches) and divide by
231. This will give the approximate capacity of the tank in gallons. The supervisory mess personnel should post the correct quantity of the standard dishwashing compound for the equipment on or near the dishwashing machine for use by subsequent operators.
