Before the high-efficiency filter is installed, it must be unpacked at the installation site for visual inspection, including: filter paper, sealant and frame for damage; side length, diagonal and thickness dimensions meet the requirements; whether the frame is smooth and No rust spots (metal frame); whether there is a product certificate, technical performance meets the design requirements. Then check according to the prescribed method, and the qualified one should be installed immediately.

2. 3. For high-efficiency filters, the installation direction must be correct: when the corrugated plate combination filter is installed vertically, the corrugated plate must be perpendicular to the ground; the connection between the vertical and the frame of the filter is strictly prohibited from leakage, deformation, damage and leakage.
