Oven

1. Scope of use
This product is widely used in industrial and agricultural production, scientific research, PCB board drying, medical and health and other unit laboratories for drying, heat treatment and heating of test samples, but it is not suitable for volatile, flammable and explosive items to avoid Cause an explosion.

2. Principle and structure 
The lower part of the working room of this product is equipped with a heating wire, and the left side is equipped with a blowing device. The temperature controller controls the constant high and low temperature. During operation, the air flows in from the air inlet at the bottom of the box, passes through the heating wire, and then flows into the working room through the blower device. Then it is discharged through the exhaust hole on the top of the box.

3. How to use 
1. Before powering on, please make sure the switch is set to the "off" position and check for open circuit or leakage. 
2. Since there will be a slight smoking process during the first heating, it is recommended not to put the sample before formal use, close the door, unscrew the exhaust cover on the top of the box, turn on the electric heating switch, the blower switch, and the indicator light will turn on. Set the heating switch to the "slow" position and set the temperature controller to 100°C. At this time, the temperature in the box begins to rise. When it reaches 100°C, the temperature controller automatically maintains the temperature. After that, the power can be cut off and the door of the box can be opened for cooling and cooling. Scatter the smoke. 
3. For formal use, first place the sample on the shelf, close the door, unscrew the exhaust cover on the top of the box, connect the power supply, and turn on the electric heating switch and air blast switch. You can choose fast or slow heating during use. Then set the temperature controller to the required temperature. At this time, the temperature inside the box begins to heat up. When the temperature is constant, the heating gear should be set to the "slow" gear to ensure constant temperature fluctuation and uniform temperature inside the box.

4. Precautions 
1. When using, the samples should not be placed too crowded to avoid affecting the convection in the box. When placing the box, please ensure that the box is effectively grounded to ensure safety. Do not touch the electrical circuit on the left side of the box with your hands or wet cloth when powering on; 
2. When heating up, please do not splash water on the observation window of the box door to avoid the glass from being cold and prone to bursting; 
3. This series of drying ovens are non-explosion-proof products; 
4. Please do not put volatile, flammable and explosive items in the box for heating to prevent explosion.
