STEP 8:
SECURE ROD / LATCH / CENTERLIFT ASSEMBLY TO DOOR
9a. Check current centerlift position using views shown.
9b. To extend latches, push and hold down on the holdback bracket to
disengage the retraction feature, then use a screwdriver inserted into the
activation slot to gently lower the slot to the extended position as shown.
9c. To retract latches, gently insert a screwdriver into the activation slot and
raise the slot to the retracted position as shown.
TROUBLESHOOTING:
If latchbolt is fully extended while activation slot is not fully in the extended
position,
then top rod is too short
. Go back to STEP 3 and correct.
If latchbolt is partially retracted while activation slot is fully in the extended
position,
then top rod is too long
. In this case, latchbolt will be fully retracted
before activation slot can travel fully to the retracted position. Go back to
STEP 3 and correct.
9d.
Bottom bolt drag check:
With top latch in retracted position, check to ensure that bottom bolt is not
extending from bottom of door a distance greater than the bottom gap at
finished floor (minus the threshold height if threshold is used).
If it is,
then bottom rod is too long
. Go back to STEP 4 and correct.
9e. Upon completion, retract latches before proceeding to Step 10.
8a. Attach back plate with two screws - DO NOT
OVERTIGHTEN.
Assembly hint:
Assemble one screw loosely
without backplate, then add second screw
through backplate. Remove first screw,
align backplate and then re-install first screw.
8b. Attach top latch with two screws.
8c. Attach bottom latch with two screws.
