• Protective Valves: Standard pressure relief valves for both opening and closing cycles protect the door and frame from damage.
• Secure Arm Engagement: 1/2" arm engagement over a 7/16" square spindle ensures a wear-resistant, tight joint.
• Included Hardware: Machine screws, self-tapping screws, and wood screws (for wood doors without through bolts) are provided.

3. Setup and Installation

The Sargent 351 O door closer offers multiple installation configurations. Refer to the specific template provided with your product for precise hole drilling and mounting instructions for standard, top jamb, parallel, or track installations.

1. Prepare the Door and Frame: Ensure the door and frame surfaces are clean and free of obstructions. Mark drilling locations according to the chosen mounting template.
2. Drill Holes: Carefully drill pilot holes as indicated by the template. Use appropriate drill bits for the door and frame material.
3. Mount the Closer Body: Secure the closer body to the door or frame using the provided machine screws, self-tapping screws, or wood screws as applicable. Ensure the body is level and firmly attached.
4. Attach the Arm Assembly: Connect the main arm to the closer spindle, ensuring the 1/2" arm engagement over the 7/16" square spindle is secure. Attach the shoe to the door frame or door, depending on the mounting type.
5. Initial Adjustment: Perform initial adjustments as described in Section 4 to ensure the door closes smoothly and at the desired speed.

4. Operating and Adjustment

The Sargent 351 O door closer features adjustable spring power and hydraulic valves to control closing speed and latching action.

4.1. Spring Power Adjustment

The spring power is adjustable, allowing the closer to be set for door sizes 1 through 6. The unit is factory-set to size 3. To adjust, locate the spring adjustment nut (typically at the end of the closer body). Turning the nut clockwise increases closing force (for heavier doors or higher wind loads), and counter-clockwise decreases it.

4.2. Closing Speed Adjustment

Two independent valves control the closing speed:

• Main Closing Speed Valve: Controls the speed of the door from its full open position to approximately 15 degrees from closed. Turn clockwise for slower speed, counter-clockwise for faster speed.
• Latching Speed Valve: Controls the speed of the door for the final 10-15 degrees of closing, ensuring proper latch engagement. Turn clockwise for slower latching, counter-clockwise for faster latching.

Important: Make small adjustments (quarter-turns) at a time and test the door's operation after each adjustment. Over-tightening valves can damage the closer. The pressure relief valves protect the door and frame from damage during both opening and closing cycles.

5. Maintenance

Regular maintenance ensures optimal performance and extends the lifespan of your Sargent 351 O door closer.

• Periodic Inspection: Annually inspect the closer body, arm assembly, and mounting screws for any signs of wear, damage, or looseness.
• Tighten Fasteners: Ensure all mounting screws and arm assembly fasteners are securely tightened. Do not overtighten.
• Clean Surfaces: Wipe down the closer body and arm with a soft, damp cloth to remove dust and grime. Avoid abrasive cleaners.
• Check for Leaks: Inspect for any signs of hydraulic fluid leakage around the closer body or valves. If leaks are detected, contact customer support.
• Re-adjust as Needed: If door operation changes (e.g., speed becomes too fast or slow), re-adjust the closing and latching speeds as described in Section 4.

6. Troubleshooting

This section addresses common issues you might encounter with your door closer.

• Door Slams Shut: The closing speed is too fast. Adjust the main closing speed valve (and possibly the latching speed valve) clockwise to slow down the door.
• Door Closes Too Slowly: The closing speed is too slow. Adjust the main closing speed valve (and possibly the latching speed valve) counter-clockwise to speed up the door.
• Door Does Not Latch: The latching speed is too slow or the spring power is insufficient. Adjust the latching speed valve counter-clockwise or increase spring power by turning the spring adjustment nut clockwise.
• Door is Hard to Open: Spring power may be set too high. Decrease spring power by turning the spring adjustment nut counter-clockwise.
• Oil Leakage: Indicates a potential seal failure. This usually requires professional service or replacement of the closer. Contact customer support.
