IMPORTANT: It is responsibility of door and frame manufacturers to check hardware schedule and prepare doors and frames. The following instructions cover field prep.

1. Prepare door and opening.

• 1. Determine hand of door for proper placement of pivot set. (Figure 1)
• 2. Confirm pivot side of door frame is both plumb and straight with respect to frame rabbet and frame face surfaces.
• 3. Mark frame header and door for top pivot. (Figure 2) Using template PS30625, note the requirement for door radius on heel edge of door.
• 4. Install jamb portion and finish plate of top pivot into frame header using two (2) 12-24 x 5/8" FHMS or #12 x 1-1/4" FHWS and one (1) 1/4-20 x 5/8" FHMS or #14 x 1-1/2" FHWS. (Figure 3) Refer to template PS30625.
• 5. Using Norton Rixson alignment tool 2608, secure plumb line to jamb portion top pivot pin. (Figure 3)
• 6. Using plumb line, locate bottom pivot floor portion spindle centerline. With bottom pivot floor portion as template, mark location of mounting holes. (Figure 3)

NOTE: Confirm floor portion placement using template PS30625 with respect to frame rabbet and frame face. If not accurate, frame may not meet straight and plumb requirements of step 2 above.

7. Radius heel edge of door for 1/8" (3.2mm) minimum clearance through entire opening per template PS30625.

NOTE: Maximum radius 1-7/8" (47.6mm) for 1-3/4" to 2-1/2" (44.5mm to 63.5mm) doors.

• 8. Mortise and prepare holes in top of door for top pivot door portion.
• 9. Mortise and prepare holes in bottom of door for bottom pivot door portion.

NOTE: Mortise depth in bottom of door must be coordinated with required clearance between door bottom and floor. 5/16" (7.9mm) Min. Clearance = 1-1/8" (28.6mm) Mortise depth 11/16" (17.5mm) Max. Clearance = 3/4" (19mm) Mortise depth

2. Install pivot set.

1. Install floor portion of bottom pivot securely to floor using four (4) 1/4-20 x 5/8" FHMS or #14 x 1-1/2" FHWS and provided lead expansion shields. (Figure 6)

NOTES:

Care must be taken that bottom pivot is level.

Center of top pivot pin must align with bottom pivot floor portion spindle. If door and frame is pre-prepped, follow steps 5 and 6 of "Prepare door and opening" to confirm this alignment requirement.

• 2. Install door portion of top pivot in door using two (2) 1/4-20 x 5/8" FHMS or #14 x 1-1/2" FHWS. (Figure 4) Refer to template PS30625.
• 3. Install door arm in bottom of door using four (4) 1/4-20 x 5/8" FHMS or #14 x 1-1/2" FHWS. (Figure 5)

3. Hang door.

Caution: Know weight of door before attempting to install. Determine proper equipment needed to prevent door from falling. (Figure 7)

• 1. Set door on floor pivot spindle and tilt top of door pivot portion into top jamb portion. (Figure 7)
• 2. Engage top pivot pin by turning pin retracting screw clockwise. (Figure 8)

To remove door:

Caution: Know weight of door before attempting removal from frame. Determine proper equipment needed to prevent door from falling. (Figure 7)

• 1. Open door enough to gain access to pin retracting screw.
• 2. Secure door so it will not fall from opening during following steps.
• 3. Turn top pivot pin retracting screw counter clockwise to disengage top pivot pin.
• 4. With door securely held, carefully allow door to rotate on bottom pivot toward closed position.
• 5. Leaning door at header to allow top of door to clear frame rabbet, lift door to clear bottom pivot spindle.
