Factory Environment

1. For indoor use

2. Environmental temperature is within ±5-45℃ 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 initially using or resuming use after a long period of disuse, an electric furnace must be seasoned to prevent the furnace chamber from cracking.

2. Keep clean regularly and check the electrical furnace wiring for good contact periodically.

3. Do not exceed the rated temperature when using the electric furnace to prevent damaging the heating elements. It is prohibited to pour any flammable liquids or molten 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, the furnace is cold and requires a significant amount of heat absorption.

After-sales service

1. We commit to resolving any technical inquiries from our clients within 1 hour.

2. We promise to provide a test result 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 of 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 for extended periods at the rated temperature 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 shortages or omissions.

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

Cooling rate should not exceed 5℃/min.

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

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

Equipment operates with voltage but no current.
