First, remove the door leaf from the wood grain of the door frame; Fold down the aluminum strip connected below the door frame, and turn the fixing pieces on both sides of the door frame to the position suitable for installation; Push the door frame into the door opening from the front of the door opening to determine the front and rear positions of the door frame; Special attention must be paid to the flatness and verticality of the door frame, and the opening distance of the door leaf between the door lock frame and the door hinge frame must be adjusted with a spirit level; After confirming that there is no problem in adjusting the size, fix the door frame fixture on the wall; Reinsert the door leaf into the half hinge of the door frame, and check whether the door leaf opens smoothly and firmly. Precautions for installation of single-opening copper doors: When installing single-opening copper doors, attention should be paid to the assembly quality, the joints should be smooth, and the assembled frame fan should not be split and fall off; Surface pollution bite color, do not pay attention to the protection of finished products during construction, not cleaned up in time; Scratches on the surface should be strictly prevented from cleaning the dirt on the flat surface with hard objects; The glass cutting size is not well grasped, and the size is not measured according to the physical object. Do not meet the installation requirements after cutting, too large or too small; Mortar and sundries in the notch are not cleaned, so they should be cleaned carefully, and glass shall not be installed without inspection; If the nylon strip and rubber strip are lost or the length is not in place, the sealing material should be selected according to the design requirements, and it should be replenished in time after being lost.
Please do not put the copper sheet of the product directly on the ground or collide or rub with hard objects during installation. This may damage the protective layer on the surface of the copper door, affect the appearance, and make the surface of the copper door more prone to oxidation. 3. When installing, please make sure that the door frame is installed firmly, with four corners vertical and horizontal and perpendicular to the wall. It is very important to ensure that the door and switch will not become loose after hanging. If the installation is not firm, it may lead to the dislocation of the door leaf, which may affect the normal switch or make it impossible to switch. Wear to the upper and lower door frames will damage the surface of the copper door, affect the appearance, and make the surface of the copper door easier to oxidize. It may also lead to accidents that endanger personal safety.
