The primary purpose of a soot purifier is to filter the smoke and grease particles generated in the kitchen, thereby reducing environmental pollution. Over time, these devices tend to accumulate oil deposits inside, which can lead to reduced efficiency. If not cleaned regularly, the purifier may fail to effectively remove soot, causing it to build up in the kitchen and potentially leading to fire hazards. Therefore, regular cleaning of the soot purifier is essential for both performance and safety.
**Step 1: Power Off and Discharge**
Before starting any maintenance, ensure the power supply to the device is completely turned off. Even if the main switch is off, there might still be residual electricity in the power box. Always turn off the main power switch outside the equipment to prevent electrical shocks. Never perform any work while the system is live—safety should always come first.
Once the power is off, open the access panel and discharge any remaining electric charge. Use an insulated screwdriver to short-circuit the cathode and anode of one of the electric fields. This helps eliminate any stored energy that could pose a risk during cleaning. At the same time, clean the internal components thoroughly to remove oil buildup, which can be a fire hazard.
**Step 2: Remove the Electric Field**
After confirming the power is disconnected, unscrew the bolts securing the electric field. Open the maintenance door (refer to Figure 2), then carefully pull out the electric field from both sides (see Figure 3). Be cautious when removing it—hold the end firmly to avoid sudden drops or damage. Remember, never squeeze or drop the electric field; lift it gently.
**Step 3: Disassemble Parts for Cleaning**
To prevent electrical leakage, remove the insulators before cleaning the cathode and anode plates. These parts must be handled with care, as water exposure can cause short circuits. Set them aside for separate cleaning (as shown in Figure 4).
**Step 4: Clean the Electric Field**
Use a large stainless steel or plastic container to soak the electric field. Place it in a bag to avoid spilling. 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, rinse thoroughly using a high-pressure water gun. Allow it to air dry in a clean, well-ventilated area (as seen in Figure 5).
**Step 5: Inspect and Clean the Insulators**
Check the insulators for signs of burning, cracks, or dirt. Replace any damaged ones immediately. Clean the insulators with rubbing alcohol and dry them with a clean cloth. Make sure they are completely dry before reassembly (as shown in Figure 6).
**Step 6: Reassemble and Check Alignment**
Once the electric field is dry, inspect the space between the anode and cathode plates for any foreign objects. Ensure there is no contact that could cause a short circuit. If any plates are misaligned, use pliers or a screwdriver to gently adjust them back into place (Figure 7). Then, clean the core of the purifier and check for any misalignment in the plates.
If any deviation is found, place the electric field on a flat surface and use a cathode deviation detector to ensure each needle is properly aligned. Only after this check should the electric field be reinstalled.
**Step 7: Test and Adjust the System**
After reassembling, turn the power back on. The indicator light should remain steady, indicating normal operation. If the light flashes or a "click" sound is heard, the electric field may need to be removed and checked again. If the cathode plates are misaligned or discharges are uneven, a "pop" sound may occur. In such cases, adjust the plates accordingly.
If the issue persists, stop the process and contact the manufacturer or dealer for further assistance. Regular maintenance ensures the longevity and safe operation of your soot purifier.
