How to Install and Adjust a Global Door Closer R7483
A Global Door Closer R7483 is a commercial door closing device that uses spring power and hydraulics to automatically close the door. It is commonly installed on aluminum storefront doors, hollow metal doors, and commercial wood doors. It provides a safe and smooth closing cycle each time a door is opened. It is also ADA compliant and has adjustable closing and latching speeds controlled by separate regulating valves.
In this article, we will show you how to install and adjust a Global Door Closer R7483 on your door. You will need the following tools and materials:
A Global Door Closer R7483 with a standard arm and a parallel bracket
A drill with a 1/4 inch bit
A Phillips screwdriver
A hex wrench
A tape measure
Mounting screws and hardware
Follow these steps to install and adjust your Global Door Closer R7483:
Determine the mounting position of the door closer. You can install it on the hinge side, the top jamb, or the parallel arm of the door. Refer to the mounting template included with the door closer for the correct dimensions and hole locations.
Drill the holes for the door closer body and the arm bracket according to the template. Use a level to ensure that the holes are aligned.
Attach the door closer body to the door or frame with the mounting screws and hardware. Make sure that the spindle is pointing towards the hinge side of the door.
Attach the arm bracket to the opposite side of the door or frame with the mounting screws and hardware.
Connect the standard arm to the spindle of the door closer body with the hex wrench. Tighten the set screw to secure it.
Connect the parallel bracket to the other end of the standard arm with the hex wrench. Tighten the set screw to secure it.
Adjust the angle of the arm and bracket so that they are parallel to each other and perpendicular to the door when it is closed.
Open and close the door several times to test the operation of the door closer. If necessary, adjust the closing and latching speeds by turning the regulating valves on the side of the door closer body with a Phillips screwdriver. The valve marked \"S\" controls the sweep speed, which is how fast the door closes from fully open to about 10 degrees before latching. The valve marked \"L\" controls the latch speed, which is how fast the door closes from 10 degrees to fully closed. Turn clockwise to slow down or counterclockwise to speed up.
Congratulations! You have successfully installed and adjusted your Global Door Closer R7483. Enjoy your safe and smooth door operation.
