How To Determine Hand of Door

Face a door swinging open away from you. If it opens to the right, it is right hand. If it opens to the left, it is left hand.

IMPORTANT:

Use plumb line to be sure that hinge pins are in perfect alignment.

1. Locating Closer

• A. Measure from the door stop 1/2 the thickness of door to determine centerline of door.
• B. To determine centerline of closer measure back towards the stop side 3/8" from centerline of door.
• C. Dim "A" is the distance from the door jamb to the centerline of closer spindle. Degree of opening (90° or 95° only) and type of butts or hinges determines correct dim "A". (see tables on reverse side). From door jamb measure dim "A".
• D. Where the dim"A" and 3/8" measurements intersect indicates the centerline of closer spindle.

2. Install Cement Case in Floor

• A. For floor plate application: Cement case is set 1/8" (3.2mm) below floor level.
• B. For 1/2" high threshold application only: Cement case is set flush with floor. (Longer spindle must be used).
• C. Set cement case in floor and block in position. LOCATE CLOSER SPINDLE USING DIM "A".
• D. Case should be parallel with center line of door.
• E. CEMENT CASE SHOULD BE LEVEL. Place levels per Illustration.
• F. Grout in cement case with closer. Cement should not get between closer and case.

3. Hang Door

• A. Mortise door and jamb for butts or hinges per template.
• B. Install rail in door per template (rail must extend to hinge edge of door so arm block may be placed in rail after door is hung.)
• C. Secure rail in place and hang door on its hinges. Use a plumb line to assure that door is in vertical alignment.

4. Attach Arm

• A. Close latch and stroke valves (Turn Clockwise).
• B. Slide arm block into rail through heel edge of door.
• C. With door almost closed slide arm onto spindle thru notch in end of arm. (Rock door back and forth to seat arm on spindle.)
• D. Secure arm to spindle with screw furnished. THE ARM SCREW MUST BE FASTENED SECURELY. (Tighten screw by rocking door back and forth.)

Closer Adjustment

Closing speeds can be adjusted to suit local conditions and requirements. Label on closer face designates the purpose of each adjustment screw.

• A. The Stroke valve allows adjustment from open position to 15°.
• Latch valve allows adjustment from 15° to closed position.
• C. Important: Backcheck adjustment must be adjusted to vary resistance from light to firm at 60° of door opening. -*
