4. Setup and Installation

The Harrison RM4000-1618 door closer is designed for hassle-free installation with versatile door and frame mounting options. Detailed installation instructions and templates are typically included with the product packaging. Please refer to these specific documents for step-by-step guidance tailored to your installation type.

General Installation Notes:

• Identify the correct mounting position on your door or frame based on the door's swing direction and desired opening angle.
• Use the provided screws and hardware for secure attachment.
• Ensure the door closer is level and aligned correctly to prevent undue stress on the door and closer mechanism.
• Test the door's operation immediately after installation to verify proper closing and opening speeds.

5. Operating Instructions

Once installed, the Harrison RM4000-1618 automatically controls the door's closing motion. The double speed adjustment feature allows you to fine-tune the closing cycle to your preference.

Speed Adjustment:

The door closer features two independent speed adjustment valves, typically located on the body of the closer. These valves control the initial closing speed and the latching speed (the final few degrees of closing).

• Initial Closing Speed: Adjust this valve to control how quickly the door closes from its fully open position until it reaches the latching point.
• Latching Speed: Adjust this valve to control the speed of the door for the last few degrees of closing, ensuring it latches securely without slamming.

To adjust, use a screwdriver to turn the respective valve. Turn clockwise to decrease speed (slower closing) and counter-clockwise to increase speed (faster closing). Make small adjustments and test the door's operation after each adjustment until the desired speed is achieved.

Door Opening Angle:

This door closer allows for a door opening angle of up to 180 degrees, depending on the door and frame configuration. Ensure there are no obstructions that would prevent the door from opening to its full intended extent.

6. Maintenance

Regular maintenance ensures the longevity and optimal performance of your Harrison RM4000-1618 door closer.

• Cleaning: Wipe the exterior of the door closer with a soft, damp cloth to remove dust and grime. Avoid using abrasive cleaners or solvents.
• Inspection: Periodically check all mounting screws and fasteners to ensure they are tight. Inspect the closer body and arm for any signs of damage, leaks, or excessive wear.
• Lubrication: The internal mechanism is factory-lubricated and generally does not require additional lubrication. If you notice unusual noises or stiffness, consult a professional.
• Speed Check: Occasionally verify that the closing and latching speeds are still set to your preference and adjust if necessary.

7. Troubleshooting

If you encounter issues with your door closer, refer to the following common problems and solutions:

• Door closes too fast/slow: Adjust the speed control valves as described in the 'Operating Instructions' section.
• Door does not close completely: Check for obstructions around the door frame. Ensure the latching speed is set appropriately. Verify that the door closer is correctly aligned and securely mounted.
• Door slams shut: Decrease the latching speed by turning the corresponding valve clockwise.
• Oil leakage: If you observe oil leaking from the closer body, this indicates a seal failure. The unit may need to be replaced. Contact customer support.
• Excessive noise: Check all mounting screws for tightness. Ensure the door closer arm is not rubbing against the door or frame.

If problems persist after attempting these solutions, contact Harrison customer support for assistance.
