Installation Instructions

• Select angle of opening and use dimensions shown on Page 4 and Dimension Chart below to locate 4 holes on door for closer body (or 4 holes for 7788 Drop Plate, Page 5, only if required) and 5 holes on stop/rabbet for Soffit Plate (or 4 holes on frame transom for 2019L bracket, only if required). For applications not covered in these instructions, a separate template will be required.
• Prepare door and frame for fasteners using "Preparation for Fasteners" chart on Page 2.
• Install closer body to door, or 7788 Drop Plate, with power adjustment shaft away from hinge edge of door and adjustment valves:

Down for Left Hand Up for Right Hand

Mount 7788 Drop Plate to door ... only if used (see Page 5).

Install Main Arm: Close valves ('S/D' or 'S') and 'L' , then using a wrench, rotate the pinion shaft at least 50° to permit alignment of the Pinion Flat with the proper arm mark:

'Z' for Left Hand 'Y' for Right Hand

• Reopen valves ('S/D' or 'S') and 'L', that were closed in previous step.
• With door closed, align soffit plate with holes in frame and fasten to frame with screws. Use 2019S and/or 6891 spacer blocks or 6890 reinforcing bracket as required.
• 7500 Series Closers only: Closer is shipped from factory set at mid-range. Using "Power Adjustment" chart below, rotate power adjustment shaft with 1/8" allen wrench supplied: Turn CLOCKWISE to increase power. Turn COUNTER-CLOCKWISE to decrease power See Page 6 for the illustration of this step.
• Make adjustments to closer before installing cover. See Page 6 for closer adjustment instructions.

CAUTION: Do Not back valves out of closer body or a fluid leak will result.

Install closer per instructions with the proper pre-load applied to the arm then adjust spring power. The power adjustment will not work properly if the closer spring is not pre-loaded. To increase power, use 11/16" wrench to turn power adjustment nut clockwise. To decrease power turn nut counter clockwise.

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 4 and Figure 5).

Friction Hold-Open Feature

Hold door open to opening angle desired and tighten holderadjustment-nut (wrench supplied) or use 1" Box or Open End wrench.

Thumbturn Hold-Open Feature

The Thumbturn Hold-Open feature is controlled by the knob located on the arm of the unit. Turning this knob clockwise will engage the Hold-Open mechanism and increase the Hold-Open force. Turning this knob counterclockwise will reduce the Hold-Open force and disengage the Hold-Open mechanism. DECREASE - - INCREASE
