- Drill Holes: Drill the necessary holes for mounting the closer body to the door.
- Secure the Closer Body: Attach the closer body using the provided screws and ensure it is level and secure.
Installing the Closer Arm
The closer arm connects the closer body to the door frame and is responsible for transferring the closing force. The installation process for the arm typically involves:
- Position the Arm: Align the arm with the closer body and the door frame.
- Secure the Arm: Attach the arm to the closer body and the frame using the appropriate mounting hardware.
- Adjust the Arm Length: Adjust the arm length as needed to ensure proper operation of the door closer.
Final Adjustments and Testing
After the closer is mounted, several adjustments and tests are necessary to ensure optimal performance:
- Adjust Closing Force and Speed: Use the provided adjustment mechanisms to customize the closing force and speed based on the door’s requirements.
- Test the Closer: Open and close the door to test the closer’s performance. Make any necessary adjustments to achieve the desired operation.
Application-Specific Considerations
