1. When going to work, turn on the water curtain of the water curtain fan for 10-15 minutes, and then turn on the negative pressure fan after the water curtain is wet; It is forbidden to open the fan first, then open the water curtain, or open the fan water curtain at the same time; The purpose of this operation is: to avoid the phenomenon of "flying water" before the water film is formed on the wet pad;
2. When getting off work, close the water curtain for 10-30 minutes, and then turn off the fan; It is forbidden to turn off the fan first, and then close the water curtain, or close the fan and water curtain at the same time; The purpose of this operation is to let the water curtain fan drain the residual water on the wet curtain, and try to keep the dryness of the wet curtain in a non-working state to ensure the service life of the water curtain.
3. When the dust in the air is working in the water curtain, it flows into the water storage tower through the backwater pipeline, which causes the water quality of the water storage tower to become dirty, and the water in the water storage tower should be replaced once every 7-10 days to ensure the cleanliness of the water quality.
4. Remove scale and algae on the surface of the wet curtain of the water curtain fan: after the wet curtain is thoroughly dried, brush up and down with a soft brush to avoid horizontal brushing. (You can brush a part of it first to check whether the wet curtain can withstand brushing.) Then just start the water supply and rinse the surface of the pad with scale and algae. (Avoid rinsing the pads with steam or high-pressure water)
