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.

ASSA ABLOY

The closing force for series 8381 & 8581 door closers is adjustable from a size 1 to a size 6, as outlined in ANSI Standard A156.4. When these series of door closers are installed and adjusted to conform to ADA reduced opening force requirements (5 lbs max.) for interior doors, they may not have adequate closing force to reliably close and latch the door. Power adjustments charted on page 4 are recommended where possible, to ensure proper door control.

Installation Instructions Regular Arm

Installation Sequence

• Select door opening angle. Using template dimensions mark 4 holes on door for closer or 4 holes ( ) for 8146 Drop Plate and 2 holes on frame for arm shoe.
• Prepare for fasteners See "Fasteners Chart", this page.
• Remove forearm screw from arm assembly and fasten the arm shoe assembly to the frame face. (Slot facing down.)
• Mount closer body to door. Place end with 2 regulating valves toward hinge edge of door. NOTE: If using full metal cover, cover mounting clips must be slipped under ends of closer when closer is being mounted.
• Install main arm on top of pinion shaft. Align the pinion flat with the letter "S" (See Figure 1). Fasten with arm screw.

Installation Sequence

• Select door opening angle. Using template dimensions mark 4 holes on door for closer body or 4 holes (*) For 8148/8158 Drop Plate and 4 holes on frame soffit for soffit plate.
• Prepare for fasteners – See "Fasteners Chart" at bottom of page 2.
• · Mount soffit plate to frame.

Install main arm on top of pinion shaft. Rotate pinion 45° toward hinge edge of door and align the pinion flat with arm mark:

"2" for left hand door

"3" for right hand door

(See figure 2 below) Fasten with arm screw.

• Fasten arm tube to soffit plate with soffit plate screw.
• Assemble arm. Open door slightly and insert rod into arm tube. Close door and adjust forearm length so that the arm elbow is 1-1/2" (38mm) from door surface. Install and tighten forearm screw.
• · Adjust Closer See Page 4.
• · Install Pinion Cap and/or Cover. See Page 4

NOTE: Architectural Covers CAN NOT be used for doors swinging over 120° using parallel mount.

*3400A and 3400MA Covers cannot be used when door swings beyond 120°.

Unit Adjustment

Closing Speed Controls (Figure 4.)

• Valve "S" Controls Sweep Range.
• Valve "L" Controls Latch Range.
• Valve "D" (Optional for all models) Controls Delay Range.

Opening Cycle

• "Backcheck" valve controls the strength of cushioning in Backcheck Range. NEVER close this valve completely – it is not to provide a positive stop. (see Figure 5 and Figure 6).
