Factory environment

1. Indoor use;

2. Environmental temperature: ±5 to 45°C range.

3. The relative humidity of the surrounding environment does not exceed 85%.

4. No conductive dust, explosive gases, or gases that can severely damage metals and cause insulation corrosion are present around the stove.

Safety Protection

1. When using an electric furnace for the first time or after a long period of disuse, it is necessary to dry the furnace to prevent cracking of the furnace chamber.

2. Keep the equipment clean and regularly inspect the electrical furnace wiring for secure connections.

3. When using the electric furnace, the temperature must not exceed the rated temperature to prevent damage to the heating elements. It is prohibited to pour various flammable liquids or melted metals into the furnace.

4. During the process, the temperature should generally not exceed 300℃ and the rate of temperature increase should be moderate. This is because, at the beginning of the heating process, the furnace is cold and requires a significant amount of heat to be absorbed.

After-Sales Service

1. We promise to address any technical inquiries from our clients within 1 hour.

2. We promise to issue the test results within 1 working day for equipment returned for repair, complete the repair within 3 working days, and handle special materials as needed.

3. Within one week after returning the equipment to the customer, conduct a follow-up visit with the user and provide free technical consultation.

Friendly Reminder

Do not operate the equipment at the rated temperature for extended periods to ensure its normal service life.

2. Carefully count and verify the quantity of goods and accessories upon receipt to avoid any inconvenience caused by under-shipping or missing items.

3. To extend the lifespan of the instrument, we recommend that the heating and cooling rates do not exceed 10℃/min.

4. The cooling rate should not exceed 5°C/min.

5. This furnace does not have a vacuum-sealed structure, thus it is not suitable for introducing flammable or explosive gases.

6. After some use, the furnace chamber may develop minor cracks, which is a normal occurrence and will not affect operation. These can be repaired using an alumina coating.

Equipment operates with voltage but no current.
