NOTE: · Where strong drafts exist, increase spring power as needed. · 351 Style door closers normally leave the factory with spring adjustment set at eight (8) turns. 5/8" Spring Adjustment Nut Figure 4 Maximum Width of Door Interior Only 2' 8" Clockwise Turns of Adjusting Nut 8 3' 0" 8 3' 6" 12 4' 0" 16 Max adjustment is approx 20 turns. Do not forcibly extend adjustment beyond limits. Adjustment Instructions (Figure 5) Minimum recommended door closing time is 6 seconds for doors opened to 90 degrees. Using 1/8" hex wrench, turn valve screw clockwise to slow down or counter clockwise to speed up door movement. Turn backcheck valve clockwise to increase intensity of backcheck action or counter clockwise to decrease checking (as desired). CAUTION: Set backcheck valve for a slight cushioning effect. It is damaging to the closer if the checking action is too abrupt. Backcheck should never be used as a door stop. Always use a door stop to stop the door.

This adjustment is done using a cam on spindle opposite from where arm mounts. Switch Roller Set Screw (2 Places) Figure 8 Adjustment Instructions IMPORTANT 1. CAUTION: Disconnect all input power beginning installation to prevent electrical shock and equipment damage. 2. Installer must be a trained, experienced service person. 3. All wiring must comply with applicable local electrical codes, ordinances and regulations. CAM IN DOOR OPEN POSITION Cam Approx 1/32" INSTALLATION 1. Mount closer/holder per instruction sheet provided. 2. Locate switch roller and cam and loosen both set screws in cam. (Figure 8) 3. Open door to desired holding position and hold open with door stop. Rotate cam until switch roller is on lower section of cam and approximately 1/32" from bottom of incline. (Figure 9) Cam should be positioned so when door closes, roller on switch will ride up incline of cam operating the switch. Tighten on set screw in cam with hex key and pull door closed. 4. Pull door open to desired hold open position. When switch roller travels down to bottom of incline, door closer will function as a standard multi-point holder. (Figure 10) Depending on door size and closer fall back, cam may need to be adjusted so that switch roller is positioned further from base of incline. When cam is positioned properly for desired door operation, tighten both set screws firmly. 1-800-727-5477 · www.sargentlock.com Copyright © 2005, 2008, 2011, 2021, SARGENT Manufacturing Company.
