The primary function of a soot purifier is to filter the fumes generated in the kitchen, thereby reducing air pollution. Over time, these devices accumulate oil deposits inside, which can significantly reduce their efficiency. If not cleaned regularly, the purifier may fail to properly filter smoke, leading to poor indoor air quality and potential fire hazards. In severe cases, the buildup of grease can cause the unit to overheat or even catch fire. Therefore, it's crucial to perform regular maintenance on your soot purifier to ensure both safety and optimal performance.
**Step 1: Power Off and Discharge**
Before beginning any maintenance, make sure to turn off the main power switch outside the device. Even if the unit’s power is turned off, there may still be residual electricity in the power box. Never work on the equipment while it is live—this could lead to serious injury. Once the power is off, open the access panel and discharge any remaining charge from the electric field. Use an insulated screwdriver to short-circuit the cathode and anode of one of the electric fields, ensuring all residual energy is released. At the same time, clean any internal oil buildup to prevent fire risks.
**Step 2: Remove the Electric Field**
After confirming the power is disconnected, unscrew the bolts securing the electric field. Open the maintenance door and carefully pull the electric field out from both sides. Be cautious during removal—hold the end firmly to avoid sudden drops that might damage the components. Always lift the electric field gently; never squeeze or drop it.
**Step 3: Disassemble Components for Cleaning**
To clean the cathode and anode plates, remove the insulators first. This is important because water can cause electrical leakage. Carefully take apart the components and set them aside for thorough cleaning.
**Step 4: Clean the Electric Field**
Place the electric field into a large stainless steel or plastic container. Wrap the unit to protect the floor from spills. Prepare a solution of caustic soda and hot water in a 1:20 ratio. Soak the electric field according to the level of oil buildup. After soaking, use a high-pressure water gun to rinse thoroughly. Allow it to dry in a clean, well-ventilated area before proceeding.
**Step 5: Inspect and Clean the Insulators**
Check the insulators for signs of damage such as burns or cracks. Replace them if necessary. Clean the insulators with alcohol and dry them with a clean cloth. Ensure they are completely dry before reassembling.
**Step 6: Reassemble and Check Alignment**
Once the electric field is dry, inspect the positive and negative plates for any foreign objects. Make sure they are aligned correctly and do not touch each other, which could cause a short circuit. If any misalignment is found, use tools like tongs or screwdrivers to gently adjust them back into place.
**Step 7: Test the Equipment**
Reinstall the electric field and restore power. The power indicator should remain steady, indicating normal operation. If the light flashes or you hear a “click†sound, remove the electric field and check the cathode alignment. If the plates are uneven or discharges are inconsistent, adjust them again. If the issue persists, stop the process and contact the manufacturer or dealer for further assistance.
Regular maintenance not only extends the life of your soot purifier but also ensures a safer and cleaner kitchen environment. Don’t neglect this important task—your health and safety depend on it.
