1. Select the matching fan air volume, which generally does not exceed 5% of the air volume handled by the purifier. (This data is for reference only. It depends on the site situation. If the selected fan air volume is greater than the maximum treatment air volume of the purifier, the purification effect of the purifier will be affected. );

2. The treatment air volume of each cooker per meter of hood is about 2000m3/h, and the total treatment air volume is determined according to the number of cookers, the length of hood and the installation position, and the specifications and models of corresponding purifiers are selected;

3. The distance between the purifier and the air outlet of the range hood is at least 3 meters to ensure fire safety and purification effect; The distance between the purifier and the fan is more than 2 meters;

4. Before the machine is installed, Zizhu environmental protection suggests that it is best to power on for a period of time to check whether the electrodes of the machine will shift during transportation or handling;

5. The air inlet and air outlet of the machine can be interchanged at will, and there must be a filter screen in the direction of the air inlet;
