1. The water used in the electric steam boiler must be softened and treated with standard water. The power must be cut off when repairing and maintaining the boiler, and pressure must be relieved.

2. The boiler must be drained every day to ensure the water quality in the boiler is clean.

3. Always check the operation status of key components such as transmission lines, feed pumps, control boxes, pressure switches and safety valves, and find out the causes and timely inspections.

4. The electric steam boiler must conduct internal cleaning and descaling work every six months or one year to ensure boiler efficiency and service life.

5. The water level gauge should be kept clean at all times and rinsed once a day to ensure that the water level is clearly visible. The safety valve moves the valve handle once a day to prevent rust failure.

6. When the electric steam boiler stops running for a long time, the power should be cut off, and the water in the boiler and pipeline should be drained to prevent freezing and rusting.

7. Do a good job of normal maintenance of the control box by listening, smelling, watching, and touching. If abnormalities are found, immediately turn off the power and repair.

8. Regularly tighten the connecting screws on the heating pipe and the nuts on the flange.

9, the heating pipe is easy to scale in the steam furnace, especially the water is harder and more likely to scale. The heating tube should be disassembled for about six months to remove scale. Re-heat the tube, pay attention to the restoration of the connection, tighten the screws on the flange, and tighten it repeatedly to avoid water leakage.

10, usually do not use the boiler, cut off the power supply, open the control box, check all the electrical components of the leakage circuit breaker, contactor and other connected nuts, the loose should be tightened to prevent poor contact with fired burnt wire And electrical devices.

11. The electric control box must not be filled with water or steam and flammable and explosive gas. When the boiler is running, the electric control box door is closed.
