When replacing some high-efficiency filters in the clean area, clean the static pressure box of the high-efficiency air filter with a clean cloth. Then, open the packing inside the high-efficiency air filter, paste the sealing strip on the air inlet side of the high-efficiency air filter, and place the filter in the static pressure box smoothly. When handling, pay attention to handle it lightly, and record the specifications, types, numbers and installation positions of the filter. When the filter is in the middle of the static pressure box, the distance between the filter and the surrounding of the static pressure box is equal. Fixed parts should be fixed at an angle to prevent uneven force or damage to the filter. Fixed nuts in the static pressure box should be tightened to make the connection between the filter and the static pressure box coincide and seal. Then open the air conditioning unit, after ventilating the system, open the packaging in the filter and replace it according to the above steps.
After installing the high-efficiency air filter, the operating system checks whether there is air leakage. When air leakage is found, the following treatment should be done: fastening fixtures or replacing sealing strips and re-installing. If the high-efficiency air filter itself leaks, a new high-efficiency air filter should be replaced. Next, install the panel of the high-efficiency air filter. When installing, install the panel in the direction marked before, and minimize the emptiness at the connection between the panel and the ceiling. Clearance, prevent dust accumulation. After installation of the high-efficiency air filter, the environment should be re-examined and verified to provide a reliable basis for the next determination of the abandonment of the high-efficiency air filter.
