Cause 1: The oil fume purifier has too much oil on the electrode plate of the electric field, and there are sundries or electric field deformation in the electric field, resulting in electric field discharge. At this time, the effect of the oil fume purifier is reduced or not.

解決方案：取下電場以進行清洗，拆下電場去除雜質或恢復變形的電場。

Solution: remove the electric field for cleaning, remove the electric field to remove impurities or restore the deformed electric field.

原因二：油煙凈化器匹配過大或者過小。設備風量匹配過大，廚房油煙通過設備的速度過快，在沒有處理的情況下就通過了凈化器，效果就會變差;設備風量過小，因廚房油煙量大，超過了設備的處理極限，會在排風口處出現(xiàn)白煙。

The second reason is that the matching of oil fume purifier is too large or too small. The air volume of the equipment is too large to match, and the kitchen oil smoke passes through the equipment too fast. If it passes through the purifier without treatment, the effect will become worse; The air volume of the equipment is too small. Due to the large amount of cooking fume in the kitchen, which exceeds the treatment limit of the equipment, white smoke will appear at the exhaust outlet.

解決方法：重配合適風量的油煙凈化器。

Solution: Refit the oil fume purifier with appropriate air volume.

原因三：風機功率不匹配。風機作為廚房油煙凈化器的輔助設備同樣具有十分重要的作用，風機功率過大會導致管道內風速過快，風扇功率過小則會導致管道風速過慢，這些都會起到凈化的反作用。

Cause 3: fan power mismatch. As the auxiliary equipment of the kitchen oil fume purifier, the fan also plays a very important role. Too much fan power will lead to too fast wind speed in the pipeline, and too little fan power will lead to too slow wind speed in the pipeline, which will play a negative role in purification.

解決方法：重配一臺適當功率的風機。

Solution: Refit a fan with appropriate power.

原因四：管道里有雜物;若管道內有雜物，如安裝管道時不慎在內部的雜物等，將增加管道阻力，影響管道風速，從而降低凈化效率。

Cause 4: There are sundries in the pipeline; If there are sundries in the pipeline, such as the sundries left inside carelessly when installing the pipeline, it will increase the pipeline resistance, affect the pipeline wind speed, and reduce the purification efficiency.

解決方法：及時將管道內雜物進行清潔，保持管道整潔。

Solution: clean the sundries in the pipeline in time to keep the pipeline clean.

原因五：在不合理的安裝情況下，它會導致排氣中的白色煙霧。安裝不合理、進出風口沒有安裝均風網、管道間隔短彎頭多、變徑口不合理等原因，都會造成排煙口出煙。

Cause 5: under unreasonable installation, it will cause white smoke in the exhaust. Unreasonable installation, lack of air distribution network at the air inlet and outlet, short pipe spacing, many elbows, and unreasonable diameter change openings will all cause smoke from the smoke exhaust outlet.

解決方案：按照正確的事宜將安裝工作一一完成并檢查，防止因安裝問題而導致的凈化效率低的問題。

Solution: Complete and check the installation work one by one according to the correct matters to prevent the low purification efficiency caused by installation problems.
