11PRODUCTIVE MAINTENANCE"Productive Maintenance" is defined as a means of keeping the appliance as efficient and productiveafter years of service as it was when new.CLEANINGCleaning the appliance on a regular basis will assure years of efficient performance andmaintain the gleaming appearance it has when new.Clean the exterior of the oven using a mild soap and water solution. Rinse with clear waterand a damp rag.Do not use a pressure washer of any kind to clean the appliance exterior or interior.CAUTIONThe oven interior must be cleaned with a cleaner that states it is "Safe onAluminum". Use of any other cleaner will severely damage the coating on theinside of the oven and it can not be repaired.Pay particular attention around the door opening, door edges and at the bottom of the doorso the door continues to close tightly. Should the paint around the door opening begin towear off, it can be recoated using a high temperature silver paint found in any hardwarestore.THERMOSTAT CALIBRATIONAll thermostats are factory calibrated and are extremely reliable mechanical devices.Thermostat calibration should be attempted only when continued experience indicatesinaccurate cooking temperatures and then only after the calibration of the thermostat hasbeen thoroughly checked.However, as the appliance becomes older the thermostat should be checked once a year inorder to make minor adjustments to the calibration.CALIBRATION CHECK PROCEDURELocate an oven thermometer or thermocouple in the center of the oven cavity.Set the thermostat to 350°F degrees, the upper element 3-Heat switch to "Low", and thelower element 3-Heat switch to "High".Allow the oven to heat for at least one hour before attempting any calibration check.Watch the red indicator lamp below the thermostat dial. When the lamp comes on the ovenelements are "cycling on", when the indicator lamp goes out the elements are "cycling off".After the oven has heated of an hour record the temperature of the oven when the indicatorlamp "cycles on".Allow the oven to continue heating and record the temperature when the indicator lamp"cycles off".Continue taking the "cycle on" and "cycle off" readings three times.After 3 complete "cycles" average the six temperature readings (add them up and divide by6). The average temperature should be within 25 degrees, plus or minus, of 350°F degrees.
