Installation Sequence

• Read Front Page.

Installation ground rules and components identification are on this page.

Match hardware to opening.

Follow "Template Information" on Page 2.

· Mark mounting holes location.

Use dimensions for hold-open or door stop angle desired. Mark position of 4 holes on door for closer (or drop plate) and 6 holes on frame for soffit plate (or 4 for 2019L angle bracket).

· Prepare holes for fasteners.

See chart below.

· Mount closer to door.

Drop plate first, if used. Place spring tube end toward the hinge edge of the door; closer with valves up for right hand door, with valves down for left hand door.

Mount arm to frame.

Fasten soffit plate (or angle bracket if flush partition) to frame. Mount 6190 bracket or 6191 clamps to hold soffit plate flat.

• Install arm on pinion top.

Close valve "S". Rotate pinion over 45° to align main arm letter "R" (right hand) or "L" (left hand) with pinion flat. Fasten with arm screw. See "Typical Installation" figure below.

· Adjust closer.

See "Unit Adjustment" on page 4.

Install cover.

See front page.

Closing Power Control

"Spring Power Adjustment Nut"

For 7500 Series Only

Set closer to desired size. For recommended sizes, refer to the Power Adjustment Chart below.

Install closer per instructions with proper pre-load applied to arm then adjust spring power. Power adjustment will not work properly if 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.

DO NOT use a power drill or driver to turn adjustment nut. This will damage closer and void warranty.

Opening Door Control

• Backcheck ("B") valve controls the hydraulic resistance to door opening. NEVER close this valve completely – it is not to provide a positive stop.
• Backcheck position ("P") valve controls the door angle where backcheck cushioning starts. Valve normally closed.

Hold Open controls are at arm elbow (models suffixed "H"). To select hold open on or hold open off and to adjust the hold open force, use screwdriver as illustrated below.
