An incorrectly installed or improperly adjusted door closer can cause property damage or personal injury. These instructions should be followed to avoid the possibility of misapplication or misadiustment.

• With or without suffix "DA" (Delayed Action) closing.

Note:

The closing force for series 7500 door closer is adjustable from a size 1 to a size 6, as outlined in ANSI Standard A156.4. When this series of door closer is installed and adjusted to conform to ADA reduced opening force requirements (5 lbs max.) for interior doors, it may not have adequate closing force to reliably close and latch the door. Power adjustments charted on pages 3,4 and 5 are recommended where possible, to ensure proper door control.

For Special Applications a separate door and frame preparation template is packed with these instructions. Use this instruction sheet for installation sequence and closer adjustments only.

Closer mounts on hinge (pull) side of door.

Top Jamb Installation

Closer mounts on frame face on opposite to hinge (push) side of door.

Parallel Arm Installation

  • It is recommended that the door, on which the door closer will be installed, be hung on ball bearing hinges. Door must swing freely.
  • A separate door stop, supplied by others, is recommended to prevent damage to the door closer, closer arm; or to the door, frame or adjacent walls.
  • Door and Frame must be properly reinforced, or use of special fasteners employed, to prevent the mounting screws from pulling out.
  • All dimensions are given in inches with corresponding metric dimensions (millimeters) in parentheses.
  • Door closer should never be installed on the exterior of a building.
