Determine the position of the two rails for fixation according to the width and height of the door panel and measure the level with a horizontal tube, and then fix it with M8 × 41㎜ square head screws. Use a tape measure to measure the distance between the horizontal rail and the wall and the two horizontal rails. Use a horizontal ruler to measure the level of the horizontal rail. Then use a small cap screw and a hexagon nut with M6.4 × 14㎜ to connect the horizontal rail connector to the horizontal rail. It is fixedly connected to the track. Make two tripods with eye angle steel, then connect them to the end of the horizontal rail with M6.4 × 14㎜ small cap screws and nuts, and fix them to the ceiling or wall with M8 × 70㎜ expansion bolts.
2, Installation of torsion spring
Place the torsion spring center bracket, nylon rubber ring, fixed flange, torsion spring that matches the weight of the door body, locking flange, reel, and bearing bracket on the galvanized steel pipe in order (distinguish left and right sides), and Pay attention to whether all parts are installed correctly. Use M8 × 41㎜ square head screws to fix the center bracket of the torsion spring to the short wooden board in the middle of the upper part of the opening, and avoid the installation position of the chain box. Use M8 × 40㎜ bolts to connect the torsion spring center bracket, nylon rubber ring, fixed flange and torsion spring, and then connect the torsion spring to the locking flange. Then, the lower end of the bearing bracket is connected and fixed to the horizontal rail connector with M9.5 × 19 large cap screws and nuts, and the upper end of the bearing bracket is fixed to the side wooden frame with M8 × 41㎜ square head screws.
3. Installation of door panels
Place the bottom seal on the bottom of the bottom door panel, and fix it from the back to the door panel with M4 × 16㎜ or M6.4 × 16㎜ self-tapping screws. Place the bottom wheel brackets on the sides of the door panel near the bottom seal. 1 # folds are placed at the top left, middle, and right three positions (the width is less than 10 feet, the middle position is one; the width is 10 feet) To 14 feet, two in the middle position; 15 feet to 18 feet in width, three in the middle position), and fixed with M6.4 × 16㎜ self-tapping screws.

Put each door panel into the established track in order, and connect the hinges and door panels with self-tapping screws of M6.4 × 16 ， to make each door panel into one.
4, the strength of the torsion spring
Wrap one end of the wire rope loop on the hook shaft of the bottom wheel bracket. Energize the torsion spring according to the specified tightening table. Do not exceed or fall a half turn of the specified number of turns. Hold the steel rod and hang the other end of the wire rope on the reel. Tighten the wire rope and lock the reel.

The "∏" bracket is made of angled steel with an eye, the lower end is connected to the motor with M8, and the upper end is fixed to the ceiling with two M8 × 708 expansion bolts. Use M6.4 × 16㎜ self-tapping screws to fix the hook seat to the middle position on the top of the top door panel and connect the hooks. Connect the power supply, observe the operation of the motor, and adjust the up and down stroke.
Use a white sheathed wire of Φ1.0 diameter to lead out from the electric switch terminal at the rear of the motor, and follow the motor hanger to the left of the opening 1.2 M away from the ground, nail a wire clip every 500㎜, and then connect On the manual switch. The wiring should be horizontal and vertical, both beautiful and reasonable.
