Installation and maintenance precautions of meltblown fabric heater

I. Precautions for Installation and Use of Meltblown Fabric Heaters

1. The meltblown fabric heater control cabinet should be installed in a dry, ventilated area with easy access.

2. When installing the meltblown fabric heater and external piping, pay attention to the inlet and outlet orientation.

3. Before use, the insulation resistance between the power input terminal and the metal casing must be measured and must not be less than 2MΩ. The relative humidity in the operating environment should not exceed 85%.

4. It is strictly forbidden to use three-phase power without a neutral wire. Be careful not to use a ground wire in place of the neutral wire. The heater operating voltage must be 220V. Do not directly use 380V. Use a three-phase, four-wire connection.

5. The normal operating pressure of the meltblown fabric heater must be within 0.3 kg.

6. It is strictly forbidden to use the meltblown fabric heater with cold water inlet at the top and hot water outlet at the bottom.

7. During installation and use, do not allow water to splash onto the meltblown fabric heater. Ensure the inlet and outlet joints are leak-proof. If water accidentally leaks onto the meltblown fabric heater, dry it or air it out before use. Otherwise, it may spark or break. Always check it.

II. Meltblown Fabric Heater Maintenance

1. Meltblown fabric heaters should be inspected annually.

2. Meltblown fabric heaters should be inspected before being put back into service.

3. Observe the operating status of the meltblown fabric heater at all times during operation. If any abnormality is detected, shut off the power supply and address it immediately.
