6. Operating Instructions (Adjustment)
The Hörmann HDC35-1 door closer allows for adjustment of its closing force and speed to suit different door types and user preferences. The closing force is adjustable within the EN 3-5 range.
Adjusting Closing Force and Speed:
- The door closer typically features adjustment valves or screws located on the main body. These control the hydraulic fluid flow, thereby regulating the closing speed and latching speed.
- Closing Speed (Sweep Speed): This controls the speed at which the door closes from its fully open position until approximately 10-15 degrees from the frame. Turn the designated screw clockwise to decrease speed (slower closing) and counter-clockwise to increase speed (faster closing).
- Latching Speed (Latching Action): This controls the final closing speed, from approximately 10-15 degrees to the fully closed and latched position. Adjust this to ensure the door closes firmly into the latch without slamming. Turn the designated screw clockwise for slower latching and counter-clockwise for faster latching.
- Backcheck (if applicable): Some models may have a backcheck function, which provides resistance when the door is opened forcefully beyond a certain point, protecting the door and frame. Adjust this according to your needs.
Iṣọra: Make small adjustments at a time (e.g., a quarter turn) and test the door's operation after each adjustment. Over-tightening adjustment screws can damage the hydraulic system.

However, if the sliding rail or pivot points show signs of friction, a small amount of silicone-based lubricant can be applied. Avoid oil-based lubricants that can attract dust.
- Ṣayẹwo iṣẹ ṣiṣe: Periodically test the door closer's operation to ensure it closes smoothly and at the desired speed. Readjust if necessary.
