To "dry out" the Hot Plate, set the thermostat dial at 250°F and turn on the power switch. Allow unit to cycle at least 15 minutes at this heat level. Reset the thermostat to 350°F allowing the same time. Then reset the thermostat to 450°F allowing the same time. Continue doing this until you reach 850° then allow the unit to maintain this temperature for a minimum of 4 hours. More time may be required if the unit has to operate in a moist environment.
If the unit is out of use for three or more days, a one-hour preheat schedule should be used, especially when exposed to high humidity and/or cool temperatures.
