Safety Information

Installation
The Harrison RM4000-1616 door closer is designed for surface-mounted installation and can be mounted on the door or the frame. Follow these steps for proper installation:
- Prepare the Door/Frame: Determine the mounting location on the door or door frame. Ensure the surface is clean, flat, and strong enough to support the door closer and the forces it will exert.
- Mark Drilling Points: Use the provided template (if included, otherwise measure carefully) to mark the drilling points for the main body of the door closer and the arm assembly.
- Drill Pilot Holes: Drill pilot holes at the marked points. Ensure the drill bit size is appropriate for the provided installation screws.
- Mount the Main Body: Secure the main body of the door closer to the door or frame using the installation screws. Ensure it is firmly attached and level.
- Attach the Arm Assembly: Connect the arm assembly to the main body of the door closer. The arm typically consists of two parts that connect and then attach to the door frame (for door mounting) or the door (for frame mounting).
- Secure the Arm: Attach the other end of the arm assembly to the door frame or door using the remaining screws. Ensure the arm is positioned correctly to allow full door movement.
- Initial Adjustment: After installation, perform an initial check of the door's closing and opening action. The door should close smoothly without slamming.
Note: For specific mounting configurations (e.g., parallel arm, top jamb), refer to the detailed diagrams that may be included with your product packaging.
Operation and Adjustment
The RM4000-1616 features double speed adjustment, allowing you to control both the initial closing speed and the latching speed (final closing speed).
- Initial Closing Speed Adjustment: Locate the first adjustment valve (often marked '1' or 'C1') on the door closer body. Turning this valve clockwise will decrease the closing speed (slower), and turning it counter-clockwise will increase the closing speed (faster). Adjust this to control how quickly the door moves from its open position to approximately 10-15 degrees from closed.
- Latching Speed Adjustment: Locate the second adjustment valve (often marked '2' or 'C2'). This valve controls the speed of the final 10-15 degrees of closing, ensuring the door latches securely without slamming. Adjust this valve similarly: clockwise for slower, counter-clockwise for faster.
Important: Make small adjustments (quarter turns) at a time and test the door's action after each adjustment. Over-tightening or loosening the valves excessively can damage the door closer or cause hydraulic fluid leakage.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your door closer.
- Cleaning: Periodically wipe the door closer body and arm with a soft, damp cloth to remove dust and dirt. Avoid abrasive cleaners or solvents.
- Inspection: Annually inspect all mounting screws to ensure they are tight. Check the arm assembly for any signs of wear or damage.
- Functionality Check: Regularly test the door's closing action to ensure it operates smoothly and at the desired speed. Re-adjust the speed valves if necessary.
- Lubrication: The internal components are factory-lubricated and generally do not require additional lubrication. If you notice squeaking or stiffness, consult a professional.
Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| Door slams shut | Closing speed (C1 or C2) is too fast. | Turn the relevant adjustment valve (C1 for initial, C2 for latching) clockwise in small increments to slow down the speed. |
| Door closes too slowly or doesn't close fully | Closing speed (C1 or C2) is too slow; insufficient power. | Turn the relevant adjustment valve (C1 or C2) counter-clockwise in small increments to increase the speed. Ensure the door closer is rated for the door's weight. |
| Door closer leaks oil | Damaged seals; valves overtightened/loosened. | Stop using the door closer immediately. Contact Harrison customer support for assistance. Do not attempt to repair yourself. |
| Door closer makes excessive noise | Loose mounting screws; worn internal components. | Check and tighten all mounting screws. If noise persists, contact customer support. |
