4. Setup and Installation
The Cal-Royal CRN900PBF door closer is designed for versatile, non-handed installation, accommodating standard, top-jamb, or parallel arm configurations. Proper installation is critical for optimal performance and safety.
4.1. Before Installation:
- Inspect Components: Verify that all components are present, including the door closer body, main arm, forearm, parallel arm bracket (if required for your installation type), and all necessary mounting hardware (screws, bolts).
- Review Template: Carefully review the provided installation template (typically included with the product) for precise hole placement and mounting instructions specific to your chosen configuration.
- Door and Frame Integrity: Ensure the door and door frame are structurally sound and capable of supporting the weight and operational forces of the door closer.
- Tools Required: Gather necessary tools such as a drill, drill bits, screwdriver, measuring tape, level, and pencil.
4.2. Installation Steps:
- Select Mounting Configuration: Determine the appropriate mounting configuration (standard, top-jamb, or parallel arm) based on your door's swing direction, frame type, and desired aesthetics.
- Position Template: Affix the installation template to the door and/or frame according to the chosen configuration. Use a level to ensure it is straight and accurate. Mark all drilling points clearly.
- Drill Pilot Holes: Using the appropriate drill bit size as specified in the template, drill pilot holes at all marked locations.
- Mount Closer Body: Securely attach the door closer body to the door or frame using the provided screws or bolts. Ensure it is firmly seated and level.
- Attach Main Arm: Connect the main arm to the closer's spindle. Ensure it is properly aligned and tightened.
- Attach Forearm: Connect the forearm to the main arm. Then, attach the other end of the forearm to the door frame (for standard/top-jamb mount) or to the parallel arm bracket (for parallel arm mount).
- Secure All Connections: Double-check that all screws, bolts, and arm connections are tightened to the manufacturer's specifications.
5. Operation and Adjustment
The Cal-Royal CRN900PBF door closer allows for precise adjustment of closing speed, latching speed, and back-check to meet specific operational requirements and user preferences.
5.1. Adjustment Valves:
- Closing Speed Valve (Valve 1): This valve controls the speed at which the door closes from its fully open position until it reaches approximately 10-15 degrees from the closed position.
- Latching Speed Valve (Valve 2): This valve controls the speed of the door for the final 10-15 degrees of its closing cycle. Proper adjustment ensures the door latch engages smoothly without slamming.
- Back-Check Valve (Valve 3): This valve provides hydraulic resistance to slow down the door's opening swing, typically engaging after 70-80 degrees of opening. It helps prevent damage to the door or frame from forceful opening.
5.2. Adjustment Procedure:
- Identify Valves: Locate the adjustment valves on the door closer body. Refer to the product diagram or manufacturer's template for exact positions.
- Adjust Speed: Use an appropriate tool (e.g., a flathead screwdriver) to turn the adjustment valves.
- Turning the valve clockwise will decrease the speed (slow down the door).
- Turning the valve counter-clockwise will increase the speed (speed up the door).
- Test and Refine: Make small adjustments (typically quarter-turns) and test the door's operation after each adjustment.
- Start by adjusting the closing speed (Valve 1) to achieve the desired general closing pace.
- Next, adjust the latching speed (Valve 2) to ensure the door latches securely without slamming or failing to close completely.
- Finally, adjust the back-check (Valve 3) if the door is opening too quickly or forcefully.
- Do Not Overtighten: Never overtighten the adjustment valves, as this can damage the seals and lead to fluid leakage.
6. Maintenance
Regular maintenance helps ensure the continued smooth operation and extends the lifespan of your Cal-Royal door closer.
- Periodic Inspection: At least once every six months, inspect the door closer and its arm assembly for any signs of wear, damage, or loose fasteners. Pay close attention to the arm joints and mounting screws.
- Cleaning: Clean the exterior of the closer body and arm with a soft, damp cloth. Avoid using abrasive cleaners, solvents, or harsh chemicals, as these can damage the finish or internal components.
- Tighten Fasteners: Re-tighten any loose screws or bolts found during inspection. Do not overtighten.
- Operational Check: Observe the door closer's operation. It should close smoothly and consistently without excessive noise, grinding, or resistance. If unusual behavior is noted, refer to the troubleshooting section.
- No Internal Lubrication: The door closer is a factory-sealed hydraulic unit and does not require internal lubrication. Do not attempt to open the closer body.
- Fluid Leaks: If any hydraulic fluid leakage is observed, the closer is likely damaged and should be replaced. Contact Cal-Royal support for assistance.
7. Troubleshooting
This section provides solutions to common issues you might encounter with your door closer.
| Problem | Possible Cause | Solution |
|---|---|---|
| Door closes too fast | Closing speed valve (Valve 1) is set too open (counter-clockwise). | Turn closing speed valve clockwise in small increments to slow down the door. |
| Door closes too slow | Closing speed valve (Valve 1) is set too closed (clockwise). | Turn closing speed valve counter-clockwise in small increments to speed up the door. |
| Door does not latch completely | Latching speed valve (Valve 2) is set too slow, or closing speed is too fast. | Increase latching speed (counter-clockwise) or slightly decrease closing speed (clockwise). |
| Door slams shut at the end of the cycle | Latching speed valve (Valve 2) is set too fast. | Turn latching speed valve clockwise in small increments to slow down the final closing. |
| Door opens too far or violently | Back-check function is not engaged or set too low (Valve 3). | Adjust the back-check valve to increase hydraulic resistance during opening. |
| Oil leakage from closer body | Internal seals are damaged, or the closer body is compromised. | This indicates a damaged unit. The closer cannot be repaired and must be replaced. Contact Cal-Royal support. |
| Door closer makes grinding noise | Internal mechanical issue or lack of fluid. | The closer is likely damaged. Replacement is recommended. Contact Cal-Royal support. |
