Adjusting the Door Height 1. For a single slide door, set the door in the closed position and adjust the door height so the Sweep Gasket lightly touches the floor and the door lines 431524 Just Touching up with the side frames. See Figure 9. To adjust Adjust Proper Bi-Part Door the height, loosen both the top and bottom Jam Door Alignment Adjustment Nuts and raise or lower the door with the welded Figure 9 nut on the Adjuster Rod. See Figure 7. 2. For a bi-parting door, set the doors in the closed position and adjust the door height so the Sweep Gasket lightly touches the floor. Use the Adjuster Rod to align the two door sections for a proper seal where the doors come together. Begin by adjusting the door height to produce a slight gap (approximately 1⬙) at the top of the doors, when the bottom of the doors are just touching. This should allow the doors to seal completely from top to bottom, when fully closed. Readjust as necessary to achieve a uniform seal. See Figure 9. To adjust the height, loosen both the top and bottom Jam Nuts and raise or lower the door with the Adjuster Rod. Tighten the Jam Nuts to lock the door in position. See Figure 7. © IMI 2001

Pull Cord Installation There are many types of devices used to control door operator. The most common are pull cord switches or stations, three button stations (i.e. open, close, stop) and radio–control. All three may be used separately, in combination, or all together. Our descriptions will deal with separate devices only. However, to use more than one type of device, you need only follow the direction for each type of device used. The control circuit is 24 VAC. Consult local electrical codes before proceeding with permanent installation.
Locate the Switches 1. Do not mount the pull cord switch in the air flow of the coils. If the pull cord switch must be mounted in front of the coils, provide an air baffle (by others) to prevent icing of the switch. (Icing of the switch in the open position will cause the door to run constantly.) The air baffle must be of adequate size to protect the pull cord itself, but not obstruct function of the coils. Air flow will move the cord and activate the switch. Consult the cold storage contractor. See Figure 20.
