2. Setup and Installation
Proper installation is crucial for the optimal performance and longevity of your door closer. This section outlines the general steps for standard arm mounting. Refer to the included template for precise drilling locations.
2.1. Tools Required
- Drill
- Drill bits (appropriate for door/frame material)
- Screwdriver (Phillips and/or flathead)
- Measuring tape
- Pencil
- Level
- Wrench (for arm adjustments)
2.2. Mounting Options
The TDC 85-DA-AL supports various mounting configurations. The most common is standard arm mounting on the pull side of the door. Other options may include top jamb or parallel arm mounting, each requiring specific templates and arm configurations.
2.3. Installation Steps (Standard Arm Mounting)
- Prepare the Door and Frame: Ensure the door and frame surfaces are clean and free of obstructions. Determine the desired mounting location based on the door's swing and traffic.
- Apply Template: Securely tape the provided mounting template to the door and frame at the chosen location. Ensure it is level and correctly aligned.
- Drill Pilot Holes: Using the template as a guide, drill pilot holes for the closer body and the arm shoe. Use appropriate drill bits for your door and frame material (wood, metal, etc.).
- Mount Closer Body: Attach the main closer body to the door using the provided mounting hardware. Ensure it is securely fastened and level.
- Install Arm Assembly:
- Attach the main arm to the closer's spindle.
- Attach the forearm (shoe arm) to the frame using the arm shoe and mounting hardware.
- Connect the main arm and forearm using the connecting screw.
- Adjust Arm Length: Adjust the length of the arm assembly so that the forearm is perpendicular to the door frame when the door is closed. This is critical for proper operation.
- Install Cover: Once the closer is mounted and the arm is adjusted, place the cover over the closer body.
Note: For detailed diagrams and specific measurements, always refer to the official installation template included with your product.
3. Operating and Adjustment
The TownSteel TDC 85-DA-AL door closer offers several adjustment valves to control the door's closing speed and latching action.
3.1. Speed Adjustment Valves
The closer typically has two or three adjustment valves, usually located on the side of the closer body. These valves control different phases of the door's closing cycle:
- Closing Speed (Sweep Speed): Controls the speed of the door from its fully open position (e.g., 90° or 180°) down to approximately 15° from the closed position. Turn the valve clockwise to decrease speed (slower), and counter-clockwise to increase speed (faster).
- Latching Speed: Controls the speed of the door for the final 10-15° of closing, ensuring the door latches securely. Adjust similarly to the closing speed valve.
- Delayed Action: This specific model features delayed action, which holds the door open for an extended period before the closing cycle begins. This is useful for allowing passage of equipment or multiple people. The duration of the delay can often be adjusted via a dedicated valve.
Caution: Do not turn adjustment valves more than two full turns counter-clockwise from their factory-set position, as this may cause fluid leakage and damage the closer. Make small adjustments (quarter turns) and test the door's action after each adjustment.
3.2. Spring Power Adjustment
The spring power of the TDC 85-DA-AL is adjustable from size 1 to 6. This adjustment controls the force required to open the door and the closing force. A higher spring size means more closing force.
- To increase spring power, turn the spring adjustment nut (usually located at the end of the closer body) clockwise.
- To decrease spring power, turn the spring adjustment nut counter-clockwise.
Note: Ensure the door meets ADA compliance requirements for opening force after adjustment, if applicable.
4. Maintenance
Regular maintenance ensures the continued smooth operation and extends the lifespan of your door closer.
- Periodic Inspection: Annually inspect the closer for any signs of fluid leakage, loose screws, or worn components. Check the arm assembly for bends or damage.
- Cleaning: Wipe down the closer body and arm with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
- Lubrication: The internal components are factory-lubricated and sealed. No additional lubrication is typically required. If the arm pivots become stiff, a small amount of silicone spray can be applied to the pivot points, avoiding contact with the closer body.
- Re-adjustment: If the door's closing speed or latching action changes over time, re-adjust the speed valves as described in Section 3.
Important: Do not attempt to disassemble the closer body. It contains pressurized hydraulic fluid. Any internal issues require professional service or replacement.
5. Troubleshooting
This section addresses common issues you might encounter with your door closer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Door slams shut | Closing speed or latching speed set too fast. | Turn the respective speed adjustment valves clockwise (slower). |
| Door closes too slowly or doesn't close fully | Closing speed or latching speed set too slow; insufficient spring power; air leakage. | Turn speed adjustment valves counter-clockwise (faster). Increase spring power. Check for fluid leaks; if leaking, replace closer. |
| Door does not latch | Latching speed too slow; insufficient spring power; arm not properly adjusted. | Increase latching speed. Increase spring power. Re-adjust arm length. |
| Fluid leakage from closer body | Damaged seals; over-adjustment of valves. | This indicates internal damage. The closer needs to be replaced. Do not attempt to repair. |
| Door difficult to open | Spring power set too high. | Decrease spring power. Ensure compliance with ADA opening force requirements. |
