3. Installation
Follow these general steps for installing the door closer. Always refer to the specific installation template provided with your unit for precise measurements and drilling locations.
- Prepare the Door and Frame: Determine the mounting location (regular arm, top jamb, or parallel arm) based on door swing and clearance. Clean the mounting surfaces.
- Apply Template: Securely tape the provided installation template to the door and/or frame. Ensure it is level and correctly positioned.
- Drill Pilot Holes: Using the template as a guide, drill pilot holes for the closer body and arm shoe bracket. Use appropriate drill bits for the door and frame material.
- Mount Closer Body: Attach the door closer body to the door or frame using the provided mounting screws. Do not overtighten.
- Assemble and Attach Arm: Attach the main arm to the closer spindle. Then, attach the forearm/shoe bracket to the door frame (for regular or top jamb mount) or to the door (for parallel arm mount). Connect the main arm to the forearm.
- Check Operation: Gently open and close the door to ensure smooth movement and proper engagement of the closer arm.
4. Adjustment
The DC3210 A1 689 M54 Door Closer features independent valves for precise control over closing speed, latching speed, and backcheck. Adjustments should be made in small increments.
- Closing Speed (Main Speed Valve): Controls the speed of the door from its fully open position to approximately 15 degrees from closed. Turn the valve clockwise to decrease speed (slower), counter-clockwise to increase speed (faster).
- Latching Speed (Latching Valve): Controls the speed of the door for the final 10-15 degrees of closing. This ensures the door latches securely. Turn the valve clockwise to decrease speed, counter-clockwise to increase speed.
- Backcheck (Backcheck Valve): Provides hydraulic resistance when the door is opened beyond a certain point (typically 70-80 degrees), preventing the door from slamming into the wall or frame. Turn clockwise to increase backcheck resistance, counter-clockwise to decrease. Note: Do not completely close this valve.
After each adjustment, test the door's operation to ensure desired performance and compliance with accessibility standards (e.g., ADA).
5. Maintenance
Regular maintenance ensures the longevity and optimal performance of your Corbin Russwin door closer.
- Periodic Inspection: Annually inspect all mounting screws and fasteners for tightness. Tighten any loose screws.
- Check for Leaks: Inspect the closer body for any signs of oil leakage. A leaking closer should be replaced.
- Clean: Wipe down the closer body and arm with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
- Arm Assembly: Ensure the arm assembly moves freely and is not bent or damaged.
