How to install the door closer

Door closer installation
a. Installation method of door closer

The most commonly used door closers are exterior door closers, and their installation methods are as follows:

The most common standard usage is to install the door closer to the hinge side and the open side of the door. When installed in this way, the arms of the door closer protrude outwards at approximately 90° to the door frame.

In the second usage, the door closer is installed on the side opposite to the hinge side where the door is closed. Usually an additional bracket provided with the door closer is mounted on the arm parallel to the door frame. This usage is usually for unwilling to install door closers on exterior doors that open outwards outside the building.

The door closer body is in turn mounted on the door frame instead of the door, and the door closer is on the opposite side of the door hinge. This usage can also be used for exterior doors that open outwards, especially those with only a narrow upper edge and no enough space to accommodate the door closer body.

In the third usage, the vertical door closer (built-in vertical door closer) is invisible upright on the inner side of the shaft of the door leaf. No screws and parts can be seen from the outside. It can be integrated with the door and can be opened and closed unidirectionally. The construction is simple.

b. Installation steps of door closer:

Generally, the installation manual provided with the door closer has an installation template, so read the manual first, and determine the installation position according to the door opening direction, the size of the door closing force, and the installation dimensions between the door closer body, connecting seat, and door hinge.

2) According to the requirements of the door closing force, the door closing force can be changed by inverting the connecting base by 180° or changing the connection position between the connecting rod and the connecting base. The greater the distance between the connecting rod and the center line of the door hinge, the smaller the closing force of the door closer, and vice versa.

3) Determine the position of the mounting screw according to the position indication on the installation template, and then drill and tap.

4) Install the door closer body with screws.

5) Install a fixed connection seat.

6) Install the driver board with screws.

7) Adjust the adjustment lever to 90° with the door frame, and then connect the connecting rod with the drive board.

8) Don’t forget to install the plastic cover, which can be used to catch the hydraulic oil leaked from the door closer.

9) After the installation is completed, check whether the fixing screws are tight, and there should be no looseness or looseness. Open the door to the maximum door opening position and check whether the hinged arm of the door closer collides with or rubs against the door or door frame.
