5 Install reinforcing spring
For Codoor’s mechanical release to work properly, the follower
spring in the lock case in the door must be capable of holding the
inside handle in a horizontal position. If the handle on the inside sags
(could be the result of the handle being screwed too tightly), or if the
follower spring in the lock case in the door appears weak, the
reinforcing spring supplied should be fitted. Follow these steps:
1. Put the outside door handle on the
Codoor unit.
2. Pass the lever handle spindle
through the square hole at the rear
of Codoor. Note: The red mark on
the follower should always point
downwards.
3. Door hung on the right:
Insert one end of the spring into the hole
on the spring holder, on the right in the
picture. Place the other end of the spring
on top of the end of the extension sleeve
that is on the left in the picture. The end
of the spring holder on the left should
then be bent into position under this end
of the extension sleeve.
4. Door hung on the left:
Insert one end of the spring into
the hole, on the right in the
picture. Unlike doors hung on the
right; the spring holder should be
adjacent to Codoor, with the
spring on top, as shown. Place the
other end of the spring holder on
top of the end of the extension
sleeve on the left, as shown. Then
bend the end of the spring on the
sleeve into position under this end
of the extension sleeve. If needed,
unscrew the sleeve some distance
from the fixing. This gives you a
longer projection to work with.
5. Fit Codoor to the door as described earlier (see section Fit to door).
