Attention Installer

Installation of cylindrical locks and latches must be through
bolted in all doors. If installation instructions are not followed this
may result in damage to the lock and void the factory warranty.
Any retrofit or other field modification to a fire rated opening can
potentially impact the fire rating of the opening, and Yale Locks &
Hardware makes no representations or warranties concerning
what such impact may be in any specific situation. When
retrofitting any portion of an existing fire rated opening, or
specifying and installing a new fire-rated opening, please consult
with a code specialist or local code official (Authority Having
Jurisdiction) to ensure compliance with all applicable codes and
ratings.

Troubleshooting

1. Check door for proper installation (see pictures to the right). Verify

1/8" between the latch and strike.

2. Check hinges. They should not be loose or have excessive wear on
knuckles.

3. If Latchbolt will not deadlock:
Either strike is out of line or gap between door and jamb is too great.
Realign strike or shim strike out towards flat area of latchbolt.

4. If Latchbolt does not retract or extend properly:

Latchbolt tail and retractor may not be properly positioned.
A. Remove lockset. Look through 2-1/8" hole and verify latchbolt tail

is centered between top and bottom of hole.

B. Remove latchbolt and insert lockset. Look through latch hole and

verify retractor mouth is centered in hole. Adjust outside rose
plate if not. (See #5 on page 2)

C. Rebore holes if necessary to line up retractor and tail.
