ATTENTION:

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

• For special applications, a separate door and frame preparation template is packed with these instructions. Use these instructions for installation sequence and closer adjustments only.
• 7500 Series closing force is adjustable from 1-6 as outlined in ANSI Standard A156.4. When closer is 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 door. Charted power adjustments in instructions are recommended where possible, to ensure proper door control.
• Adjust closing time speed between 3 7 seconds from 90° 0°.
• These door closers should NOT be installed on exposed side (weather side) of exterior doors.

• Minimum top rail of door with frame stop for PULL Side mount is 3-1/2" (89mm) without drop plate; 2-5/8" (67) with 7786JP drop plate. Minimum top rail of door with frame stop for PUSH Side mount is 6" (152mm) without drop plate; 2-5/8" (67) with 7786JP drop plate.
• Doors should be hung on ball bearing or anti-friction hinges.
• A separate door stop is recommended.
• Always consult door/frame manufacturer for fastener compatibility.
• Door and frame must be properly reinforced.
• Dimensions are given in inches (millimeters).

Door Opening Angle and/or Hold Open Angle (Figure 5)

Remove 9/64" hex drive socket head screw from arm. Open door to desired angle and install hex-drive socket head screw into hole in adjusting rod that is aligned with hole in adjusting tube.

On/Off Hold Open Feature (Figure 6)

Slotted screw, accessible through hole in face of track, engages or disengages hold open feature with 1/4 turn of screw. Hold open units are not permitted in fire door assemblies.

Hold Open Power Adjustment (Figure 6)

If more hold open power is required, power may be increased by turning adjustment screw in end of the track nearest hinges. Use 9/64" hex wrench provided and rotate adjustment screw clockwise to increase holding power.

Closing Power

7500ST Models are fully adjustable for proper sizing. (Figure 7)

To adjust closer power, install closer per instructions with proper pre-load applied to arm then adjust spring power.

NOTE: Power adjustment will not work properly if closer spring is not pre-loaded.
