Care and maintenance work surface with a soft cloth to wipe the oven) on a clean surface to keep the oven clean laboratory oven, to prevent stripping affect the appearance of the surface. 2) in the oven should be kept clean, so as not to adhere to the interior of corrosive substances, affecting the life of the oven. 3) The temperature must not exceed the specified baking temperature of this machine. 4) must not be blocked duct and wind hole, in order to ensure normal supply duct. 5) hear abnormal sounds in the baking process should immediately stop working, check the motor and wind wheel, so as not to burn out the motor. 6) high-temperature oven after baking items, can not immediately turn off the main switch, fan switch should be opened to let the heat dissipate only after the shutdown, in order to avoid local heating oven deformation. Drying oven factory production cycle mode of operation, a variety series hot air circulation oven, for health units and other departments do laboratory drying, baking, heat treatment and other heating widely used. The operating temperature of the oven, at room temperature can rise 20 ℃ until the maximum temperature only, in accordance with the work within this range may require non-standard electric oven, arbitrarily selected operating temperature, selected after a reliable automatic thermostat temperature controller box, temperature sensitive instrument control, high precision, welcomed by users. The oven does not apply with volatility, using explosive items, to avoid danger. Non-standard blast oven | Longkou experimental furnace (certified) | oven experiment by Longkou Furnace.
