BEFORE FIRST USE
Before using the oven for the first time, it must be "burned in" to release any odors that might result from
heating the new surfaces in the chamber.
1. Using a clean damp cloth, wipe the inside of the oven, including the racks.
2. Close the oven doors, push the On / Off / Cool Down switch ON, turn the Thermostat to 300°F (
149°C)
and allow the oven to cycle for 6 to 8 hours before turning the On / Off / Cool Down switch OFF.
USING THE HEC20D OVEN
Preheating
1. Close oven doors. Push On / Off / Cool Down switch to ON position. The HEAT light will come on,
indicating that power to the oven is on.
2. Set THERMOSTAT as desired. Refer to SUGGESTED COOKING GUIDELINES for temperatures
and times for various products.
3. Prepare product and place in suitable pans. When READY light comes on, oven has reached
desired preheat temperature.
Cooking
1. Open doors and load the product into the oven. Place pans in the center of the racks. Close doors.
2. Set COOK temperature and time. Set HOLD temperature and PULSE time, if desired. PULSE time
may not be more than COOK time. PULSE will cycle the fan during the set time at the beginning
of the cooking cycle.
3. Press the START / STOP button to start the cooking cycle.
4. At the end of the cooking cycle, the alarm will sound continuously if the HOLD mode is OFF. If the
HOLD mode is ON, there will be a short beep at the beginning of Second Stage Cooking (oven
temperature will begin to decline to the HOLD temperature), and a long beep (20 seconds) at the
end of the cooking cycle. Refer to COOK AND HOLD OPERATION.
5. When product is done, open doors and carefully remove cooked product from the oven. Wipe up
any spills.
End of Day
1. Push On / Off / Cool Down switch to COOL DOWN. Leave the door ajar while the fan is on to cool
the oven.
