Installing A Hydraulic Door Closer

Door closers are common in commercial properties, but can also be installed in residences. Door closers help reduce energy costs by ensuring that doors are always fully closed, which is especially necessary in extremely hot or cold climates.

There are many types of door closers on the market, but in general they perform the same function and have similar installation procedures.

The most common method of door closer installation is called regular arm installation. This is where the closer is installed on the hinge side of an in-swinging door.

1. Select the door opening and mark four (4) holes in the door for the door closer body and two (2) holes in the door frame for the door closer arm .

2. Drill pilot holes in the door and door frame for the supplied universal screws, or drill or tap holes for the supplied machine screws.

3. Attach the front arm/arm shoe assembly to the door frame using the screws provided with the door closer.

4. Mount the door closer to the door using the screws provided. The speed adjustment valve must be positioned towards the edge of the hinge.

5. Install the main arm onto the top pinion shaft, perpendicular to the door, as shown below. Secure tightly with the arm screw/washer assembly provided.

6. Adjust the length of the front arm so that the front arm is perpendicular to the frame when assembled to the preloaded main arm. Secure the front arm to the main arm with the provided screw/washer assembly.

7. Snap the pinion cover onto the shaft at the bottom of the door closer.

8. Adjust the closing speed of the door (see below).
