Revolving doors reduce the amount of heat, or air cooled by an air conditioning system, that is able to escape from a building while maintaining the potential for a constant flow of people. The installation of a revolving door is therefore an effective method of reducing energy bills in an environmentally friendly manner. Revolving door installation requires the clearing and drilling of a location prior to assembly of the door frame, however; so pedestrian traffic can be affected for several days during construction.
You Will Need
Clear the area where the door is to be installed, removing any existing doors and any furniture surrounding the doorway. Consult the documentation provided with your revolving door, to determine the placement of the door’s center lines. Mark the center lines on the floor using chalk.
Lay the door’s installation template on the floor with the center lines on the template aligned with the chalk markings. Fit a 1/2-inch diameter drill bit to the hammer drill. Drill a 2 1/2-inch deep hole in the floor at the center and anchor marks on the template, using the hammer drill.
Unclip and remove the canopy cover from the canopy section of the revolving door frame. Locate the speed control in the top of the door frame. Open the speed control. Fill the speed control with the oil that came with the revolving door. Close the speed control. Lift the canopy to the top of the door frame. Screw the canopy in place using the screws provided with the revolving door.
Lay out the vertical posts on the ground, with the number on each post visible. Line up the numbered posts up with the corresponding numbered position on the canopy. Screw the posts to the ceiling through the canopy, using the bolts and screws provided with the revolving door. Screw the inner base sections to the bottom of the vertical posts using the machine screws provided.
Attach anchor bolts to the bottom of the posts, to anchor the posts to the holes you drilled in the floor. Prepare a batch of cement from one part cement, three parts sand and one part water. Pour the cement into the anchor holes, surrounding the anchor bolts. Wait 72 hours for the cement to set fully before continuing.
Draw a circle 5 5/16-inches in diameter in the middle of a piece of flooring that will sit under the middle of the revolving door. Draw a line straight across the flooring using a ruler, bisecting the circle you drew. Cut the Flooring in half along the line, using a tile cutter or jigsaw, depending on which is more appropriate for the flooring. Cut out the semicircles from both halves of the flooring.
Screw the pivot bearing together. It will be provided in two pieces, which must be fastened together before use. Lay the two halves of flooring above the pilot hole you drilled in the center of the chalked center lines. Stand the pivot bearing in the circular hole in the floor pieces. Cut shims and place these under the pivot so it sits 1/8-inches from the floor. Fill the gap between the floor and the bearing with cement.
Unscrew the bolts on the end of each hanger on the disc on the top of the center shaft. Remove the hangers from the disc. Lift off the plate at the top of the shaft with the serial number on it. Unscrew and remove the set screw under the plate. Push the shaft back into the disc.
Sit the bottom of the shaft in the hole in the pivot bearing. Extend the shaft upward so the top of the disc at the top of the shaft sits in the square opening in the underside of the speed control. Screw the set screw back in place. Replace the serial number plate.
Apply grease to each of the hangers you removed. Screw the hangers back in place on the disc at the top of the center shaft. Each hanger is numbered and must be screwed back into the correspondingly-numbered slot. Check the numbers on each door, or “wing”. Align the wings with the correspondingly numbered hangers. Slide the wings onto the hangers. Screw the wings in position using the screws provided with the door.
