1. Before installing the high-efficiency filter in the Dongguan clean room, the clean room must be thoroughly cleaned and cleaned. If dust accumulates inside the air-conditioning system, it should be cleaned and cleaned again to meet the cleaning requirements. If high-efficiency filters are installed in the technical mezzanine or suspended ceiling, the technical mezzanine or suspended ceiling should also be thoroughly cleaned and cleaned.
2. After the dust-free workshop in Dongguan and the purification air-conditioning system meet the cleaning requirements, the purification air-conditioning system must be commissioned. After running continuously for more than 12 hours, install the high-efficiency filter immediately after cleaning and cleaning the dust-free workshop again.
3. The transportation and storage of high-efficiency filters should be set aside in the direction of the manufacturer's logo. Handle with care during transportation to prevent severe vibration and collision.
4. Before installing the high-efficiency filter in Dongguan clean room, the package must be unpacked at the installation site for visual inspection, including whether the filter paper, sealant and frame are damaged; whether the side length, diagonal and thickness dimensions meet the requirements; the frame has No burrs and rust spots (metal frame); whether there is a product certification, whether the technical performance meets the design requirements. Then perform a leak test. Installed immediately after inspection and leak detection. The installation should be reasonably adjusted according to the resistance of each filter. For one-way flow, the difference between the rated resistance and the average resistance of each filter between the same air outlet or the air supply surface should be less than 5%. High-efficiency filters for cleanrooms with a degree rating equal to or higher than 100,
5. The frame where the high-efficiency filter is installed should be flat. The allowable deviation of the flatness of the mounting frame of each high-efficiency filter is not more than 1mm.
6. When the seal between the high-efficiency filter and the frame of the Dongguan clean room uses the gasket, sticker, negative pressure seal, liquid tank seal and double ring seal, etc., the packing surface, filter frame surface and frame surface must be sealed. Wipe clean with liquid tank.
7. When using a gasket, the thickness of the gasket should not exceed 8mm, and the compression rate is 25% to 30%.
8. When the liquid tank is sealed, the height of the liquid surface in the liquid tank must meet the design requirements, and there must be no liquid leakage at each joint of the frame. When using double-ring seals, do not block the holes in the ring cavity when sticking the seals; both double-ring seals and negative pressure seals must keep the negative pressure pipelines open.
