Before You Begin:

• y The Americans with Disabilities Act (ADA) requires that doors having door closers have an opening force not to exceed 5 lbf.
• y Door closer's power size adjustment feature may require adjustment to its lowest setting to comply with ADA opening force guidelines.
• y ADA compliant closers may not latch doors, manufacturer does not guarantee latching on lower opening force settings.
• y A separate auxiliary door stop, supplied by others, is strongly recommended to avoid damage to door closer and adjacent property.
• y Doors should be hung on ball bearing or anti-friction hinges/pivots. Door must swing freely. For other hanging means a special layout may be required, consult factory.
• y Door and frame must be reinforced for attaching screws.
• y All dimensions are given in inches (millimeters).

Installation

A. Verify frame and door installation.

• 1. Determine if right hand or left hand installation. (Figure 1)
• 2. Verify frame is square by using a carpenter's square. (Figure 2)
• 3. Note if gaps between door and frame are consistent. Gap should be 1/16" (1.6) at jamb and header.
• 4. Using supplied templates, confirm all dimensions of cut-outs.

B. Install closer.

1. Install closer in prepped frame with four (4) 1/4-20 x 5/8" FHPMS mounting screws provided. (Figure 3)

NOTE: Mounting plate should be flush with frame rabbet.

C. Install cover plate.

1. Install cover plate to closer mounting plate using a T10 Security Torx bit with six (6) 6-32 x FHMS-TORX mounting screws provided. (Figure 4)

D. Attach arm.

1. Using a T30 Security Torx bit and 1/4-20 x 3/4" Torx screw with Patch screw and washer, attach arm to closer spindle. (Figure 5)

IMPORTANT: Arm should rest at 15° away from door side of closer mounting plate. Arm always rotates in direction of door.

Installation (cont.)

E. Assemble track.

1. Slide track components into track. (Figure 6)

NOTES:

• y All track components must be placed in track before installing track into door.
• y Stop block should be last component at hinge side of track.
• y The longer end of slider should be pointed towards hinge end of track.

F. Install track to door.

• 1. Make sure slider and track components are installed prior to installing track to door.
• 2. Install track and, if necessary, optional retrofit spacer (replacement application only, consult factory) using a T30 Security Torx bit with four (4) provided 1/4-20 x 3/4-FHMS-TORX screws for metal door. (Figure 7)

G. Attach arm to track.

• 1. With provided 1/8" hex wrench, completely tighten latch and sweep valves by turning screws clockwise. This will allow for an easier closer-to-door connection. (Figure 8)
• 2. Open door to about 45° then rotate arm over to door.

NOTE: Arm should maintain position because latch and sweep valves have been tightened.

3. Align slider square with arm square and connect using a T30 Security Torx bit with provided 1/4-20 x 3/4-FHMS-TORX with Patch screw. (Figure 9)

NOTE: If door is to be open beyond 45°, backcheck may need to be adjusted counter clockwise to easily rotate arm to door position.

Installation (cont.)

H. Install removable stop.

After closer is installed and all adjustments are complete, install removable stop.

NOTE: DO NOT drill holes into closer cover plate.
