This image displays the Corbin Russwin DC6000 Series door closer, featuring a silver-colored cast iron body and a parallel arm assembly. The main body of the closer is rectangular, and the arm extends from one end, designed for parallel arm mounting applications.
Setup and Installation
The DC6000 Series door closer is designed for screw-in installation and supports parallel arm mounting. Detailed templates and instructions are provided with the product packaging for specific door and frame types. Professional installation is recommended to ensure proper function and compliance with safety standards.
Key Installation Steps:
- Determine Mounting Location: Identify the correct mounting position on the door or frame based on the provided template for parallel arm installation.
- Prepare Mounting Surface: Drill pilot holes as indicated by the template. For through-bolt applications, use the provided sex nuts and bolts for secure fastening.
- Mount Closer Body: Secure the closer body to the door or frame using the self-drilling screws or sex nuts and bolts.
- Attach Arm Assembly: Connect the main arm to the closer spindle and the parallel arm bracket to the door frame. Ensure all connections are tight and secure.
- Initial Adjustments: Perform initial spring power and closing speed adjustments as described in the 'Operating Instructions' section.
- Retrofit Plates: If replacing an existing closer, utilize retrofit plates as necessary to match previous mounting hole patterns.
Operating Instructions and Adjustments
The DC6000 Series door closer features adjustable closing speed and latching speed, as well as a spring adjustment mechanism to control closing force.
Adjusting Closing Speed:
- Locate the two captured adjustment valves on the closer body. These typically control the main closing sweep and the latching speed.
- Turn the valve clockwise to decrease speed (slower closing) and counter-clockwise to increase speed (faster closing). Make small adjustments (quarter turns) and test the door's operation after each adjustment.
- The first valve usually controls the main sweep from the open position to approximately 15 degrees from closed. The second valve controls the latching speed for the final 15 degrees of closing.
Adjusting Spring Power:
- The spring adjustment mechanism allows for varying the closing force, which is crucial for ADA compliance and door size/weight.
- Use the appropriate tool (e.g., an Allen wrench) to turn the spring adjustment screw. Turning clockwise increases closing force; counter-clockwise decreases it.
- Ensure the door closes reliably and smoothly without excessive force. For ADA compliance, the opening force should not exceed specified limits.
Maintenance
Regular maintenance ensures optimal performance and extends the lifespan of your Corbin Russwin DC6000 Series door closer.
- Periodic Inspection: Annually inspect all mounting screws and arm connections for tightness. Tighten any loose fasteners.
- Check for Leaks: Inspect the closer body for any signs of fluid leakage. The robust spring tube design and double O-rings are designed for longevity, but any leakage indicates a need for professional service or replacement.
- Cleanliness: Keep the closer body and arm assembly clean from dust and debris. Use a soft, damp cloth for cleaning. Avoid abrasive cleaners.
- Functionality Test: Periodically test the door's closing and latching action. Readjust speeds or spring power if the door is not operating as desired.
Troubleshooting
Refer to the following common issues and solutions for the DC6000 Series door closer:
| Problem | Possible Cause | Solution |
|---|---|---|
| Door closes too fast/slow | Improper adjustment of closing/latching speed valves. | Adjust the appropriate speed valves (see 'Operating Instructions'). |
| Door does not close completely or latches weakly | Insufficient spring power or latching speed. | Increase spring power or latching speed (see 'Operating Instructions'). Check for obstructions or door/frame misalignment. |
| Door is difficult to open | Excessive spring power. | Decrease spring power (see 'Operating Instructions'). Ensure compliance with ADA opening force requirements. |
| Oil leakage from closer body | Internal seal failure or damage. | Contact a qualified technician for service or consider replacement. |
