Precautions for using a high pressure steam cooker

Here are the key points for operating a steam boiler safely and effectively:

1. **Operating Pressure**: Ensure the operating pressure does not exceed the rated pressure. For steam boilers without a pressure vessel certificate, the operating pressure must remain below 0.09 MPa.

2. **Steam Addition**: When adding steam, open the steam inlet valve slowly to avoid sudden pressure changes.

3. **Calibration**: Regularly calibrate the safety valves and pressure gauges to ensure they function correctly.

4. **Pressure Monitoring**: During operation, especially with high-pressure boilers, closely monitor the pressure gauge. If the pressure is too high and the safety valve hasn't vented, slowly open the vent valve to release excess pressure.

5. **Empty Boiler Operation**: Never open the steam valve, electric heating power supply, or gas switch when the boiler is empty (without a heat-absorbing medium). This can cause damage to the boiler.

6. **Low Water Levels**: If the boiler's water level is too low and the dry burn protection device activates, slowly open the exhaust valve. Once the pressure gauge returns to "0," open the water inlet valve to add water. After refilling, close all valves and restart the electric heater to continue heating.

7. **Operator Safety**: Be cautious when working in areas with inadequate insulation, such as the upper head, to avoid burns.

8. **Gas Boiler Operation**: After installing the gas pipe, turn on the gas source and connect the gas burner to a 220V power supply. The burner will automatically ignite. Adjust the air intake to control the flame size.

These precautions help ensure the safe and efficient operation of the steam boiler.
