1. Before installing the first to be installed to ensure that the ceiling space WeiChu no leaking, no cracks, water, electricity and other facilities to ensure that the appropriate completed have been laid. Mounting surface and then also test it if there is enough strength, if reinforcement measures should be taken to meet the requirements; according to the desired height to calculate the electrical pre-installed after the ceiling height of the remaining space in the room, so that the line in the corner installation. 2, in the case of the top of the tiles, while the wall to take a little off the ground 230-240cm tall, with transparent pipes fixed on the other side of the wall and bounced coincidence point line, after a good punch position drill with diamond head holes. If the height of the ceiling tiles can be used to determine the height of the case, you can use wood length 3cm * wall thickness, with the nail strips of wood fixed on the top of the wall tiles, according to the mounting height determined by the fountain pop up on wood horizontal installation revenue side bar. 3, first of all, a good amount of size on the ceiling, the drilling screw screwed into the expansion tube, and ensure that the interlayer height between the ceiling and the roof is not less than 25cm (Note: the attachment screw with the ceiling as a reference the entire ceiling of the installation, the screw must be perpendicular to the ceiling, and firmly fixed, must remain parallel to each screw. Top general case only six of the screw, you can make the whole ceiling is very strong.) Then, without affecting the electrical installation of the case, take an average of six ceiling points and then hammer drilling. 4, the first is connected with the large install the main keel hanging pieces, and the main card in the major keel hanging pieces, according to space and select the desired main keel interception. Main keel card loaded into the main keel should check whether the parallel, if not parallel should be adjusted. Followed by a triangular keel and keel are connected to the main root of the number of main keel, the triangle keel hanging pieces set into the triangle, the triangle hanging pieces in turn fixed to the main keel, and pay attention to the spacing between 300mm raised triangular keel after fixation . 5, the first pinch off the edges of the film, but not completely removed, so there is easy to install in accordance with the direction of the arrow film. Installation should be wearing a good pinch of white gloves. First-breasted front panel installation should consider the possibility to do the cutting, consider the overall appearance and symmetry on both sides as much as possible when cutting, cut side against the wall with a knife, in consideration of the flatness of the wall, and called around pinch should be smaller than the actual size of 1mm. Cutting method: with a knife and straightedge portray more than 5 times, 18mm high hem cut with scissors cuts a 90 ° angle, repeatedly folded hands 3-5 times can be. Stuck in the triangle keel, notched face frame on the income side of the bar and pull the card close to the corners of the board buckle tight. So to complete the installation of the first row of the pinch. Be sure to control the gap between first-breasted board, because the future depends on the first row of the whole installation pinch installation. Installation should be done pinch pinch spacing is 0, pinch the corners of a "ten" shape, pinch surface height should be consistent.
