INTRODUCTION

The CRL Jackson® 1000 Series Ultimate Overhead Conealed Door Closer is designed for use with larger and heavier doors weighing up to 1,000 pounds (453 kg). It features an adjustable multi-sizing spring force range of 1 through 6 to allow control of a wide range of door weights and sizes. These 180º degree swing, double acting, non-handed closers are available in dual 90º/ 120º hold-open or non hold open models.

Center-Hung and Offset accessories available include interchangeable extension spindles, center-hung and offset arm and slide-track assemblies, bottom pivots, cover plates, and multiple accessories for use with wood, metal or glass doors.

The rapidly changing technology within the architectural aluminum products industry demands that C.R. Laurence/U.S. Aluminum reserve the right to revise, discontinue, or change any product line, specification, or electronic media without prior written notice.

11. Secure the clamping block to the end-load arm with (2) 5/16-18 x 1" socket head screws.

SIDE-LOAD ARM INSTALLATION

12. To center the door it must be open to 90 degrees to access the Centering Screws, each centering screw must be fully extended to the inside of the door rail by tightening one and loosening the other, to prevent the arm from spinning. NOTE: Over-expanding the centering screws can permanently bulge the door rail. Adjust the door's vertical alignment by loosining the Holding Screw, adjust the Vertical Adjustment Screw. When the door is correctly positioned, tighten the Holding Screw down firmly.

END-LOAD ARM INSTALLATION

13. To center the door it must be open to 90 degrees to access the centering screws, each centering screw must be fully extended to the inside of the door rail by tightening one and loosening the other, to prevent the arm from spinning. NOTE: Over-expanding the centering screws can permanently bulge the door rail.

OFFSET ARM INSTALLATION

14. Mount the arm on spindle and secure it with 1/4-20 x 7/8" socket head cap screw.

OFFSET BOTTOM PIVOT INSTALLATION

15. Secure the bottom pivot to the door rail with (4) 1/4-20 x 3/4" flat head machine screws.

16. Secure the bottom pivot to the door jamb with (4) 1/4-20 x 3/4" flat head machine screws.

SLIDE CHANNEL INSTALLATION

17. Mount the slide channel and secure it with (3) 8-32 x 3/8" flat head machine screws.

OFFSET ARM TO SLIDE CHANNEL INSTALLATION

18. Lift the door onto the offset bottom pivot and swing the door in the open position and slip the arm over the slide pin and secure it with the pin retainer.

CLOSER ADJUSTMENT

• 1. Check that the door returns to the center closed position. Adjust the center position of the door by using the Centering Adjustment Gears on either side of the closer mechanism. (See Page 03)
• 2. Adjust the speed control nut to control a smooth closing speed of approximately 5 to 7 seconds from a 90° degree open position.
• 3. The 1000 Series UOHC Closer features a spring power range of size 1-6. The Chart on the right shows the approximate amount of the full turns required to advance from '0' thought the spring power range up to size '6'. The standard factory setting is at approximately mid-range, size '3', so to increase to size '4' will require three additional full clockwise turns or to decrease to size '2', two full counter-clockwise turns.

4. Oversize doors may require an increase in the backcheck resistance. Adjust the larger hex nut clockwise to increase the power of the spring or counter-clockwise to decrease the power.

5. Attach the Dress Cover Plate when all adjustments are completed.

NOTE: Although the 1000 Series UOHC Closers feature adjustable spring power that allows these closers to be set to comply with A.D.A. specified opening forces, they may not provide adequate spring force to control and close the door due to minimized closing force, varying site conditions, and door size.
