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.

Butt Hinges or Offset Pivots Right Hand Installation

IMPORTANT:

Use plumb line to make sure that center line of top pivot pin lines up with center line of closer spindle.

1. Locating Closer

• A. Measure from push side of door 1/2 the thickness of the door to determine centerline of door.
• B. To determine centerline of closer measure back towards the stop side 3/8" from center line of door.
• C. Where the 4-1/8" and 3/8" measurements intersect indicate the centerline of closer spindle.

2. Install Cement Case in Floor

• A. Cement case is set flush with finished floor.
• B. Set cement case with closer in floor and block in position.
• C. Case should be parallel with center line of door.
• D. CEMENT CASE MUST BE LEVEL. Place levels per Illustration.
• E. Grout in cement case with closer. Cement should not get between closer and case.
• F. If centerline of closer needs position adjustment, loosen hold down screws (4) and reposition closer. Tighten hold down screws closest to spindle first then tighten screws at cylinder end. Note: Closer must be lifted approx. 1/8" before repositioning.

Closer Adjustment

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

• A. The stroke valve allows adjustment from open to 15°.
• B. The latch valve allows adjustment from 15° to closed position.
• C. IMPORTANT: Back check valve option must be adjusted to vary resistance from light to firm at 70° of door opening. FAILURE TO DO SO MAY RESULT IN DAMAGE TO THE CLOSER AND RELATED HARDWARE.
• D. The delay valve option allows closing speed adjustment from open position to 65°.
• E. This closer is NON-HOLD-OPEN factory set, no hold open adjustment.

Note: With independently hung doors, on 53 closer, an auxiliary heavy duty door stop is required.
