However, in order to minimize the door open as well, so as not to affect the thermostat. Especially when operating above 200 ℃, it is possible to open the door so that the door glass quench cracking. 7. blast oven, and the temperature of the heating process must be the blower is turned on, or affect the temperature uniformity of the chamber and damage the heating elements. 8. After the work is completed in a timely manner should cut off the power supply to ensure safety. 9. To keep the oven clean inside and outside. 10. use, the temperature should not exceed the maximum operating temperature of the oven. 11. When you use a special tool to prevent burns, the test to take place.
