2. If it is necessary to cut the cable to a shorter
length, pull about one foot of inner cable from the
Type N550 latch block cable end (end with the 3/16
by 1/2-inches (4,8 by 13 mm) long cylindrical cast
fitting, see Figure 3) from the housing.
At the remote release end (other end of inner
cablehousing assembly), cut the housing and
inner cable at desired length. Push the excess
inner cable back through the housing so that the
bare cable extends from the remote release end.
3. Close the Type N550 valve. Handle parallel to pipe.
4. If necessary for additional working space, remove
the long end of the external spring from under the
latch block. DO NOT REMOVE SPRING
FROM HANDLE.
5. Loosen the slotted screw, Figure 3, on the
Type N550 valve's latch block until the plunger
can be pulled from the latch block.
6. Disconnect the short looped cable and remove it.
7. Insert the Type P164B inner cable end cylindrical
cast fitting through the latch block rear conical
hole and connect the cylindrical cast fitting into the
side slot in the plunger.
8. Replace the plunger in the latch block, oriented
so the screw will enter the plunger slot. Tighten
the screw.

9. The end of the cable housing and cable housing
nut fit into the conical end of the latch block.
Pulling the excess inner cable through the housing
from the remote release end will hold the housing
in the latch block.
10. Mount the remote release cylinder assembly to a
suitable support at the remote release location
[7/16-inch (11 mm) diameter mounting hole] but
do not tighten the mounting nut.
11. At the remote release end, strip about 3/4-inch
(19 mm) of vinyl cover from the cable housing end.
12. Insert the inner cable completely through the
release cylinder. Screw the bare cable housing
end into the remote release cylinder by rotating
the cylinder. Tighten the mounting nut.
13. Pull any slack from the inner cable, just tight
enough so that the latch is not activated, and
cut the inner cable off 1-inch (25 mm) past the
remote release cylinder end.
14. Insert the 1-inch (25 mm) bare inner cable
into the remote release handle shaft. Push the
remote release handle completely into the
remote release cylinder. Tighten the handle set
screw to secure the handle to the inner cable.
