12 ) and continue to the next sprinkler, there are no corrective actions
needed.
Figure 12 : Assembly Body type
c. In case the Assembly Body cannot be visually identified, or is identified as
A1000, remove the sprinkler by opening it with the correct sprinkler key or
with a sprinkler dismounting tool (see Figure 05 ).
-Do not use excessive force or you might damage the sprinkler cage.
-Use a rag or a bucket when removing the sprinkler to catch water
collected in the assembly body.
d. Inspect the Assembly Body. If it is NOT type A1000 (see Chapter 3) then log
the type in the follow up sheet (see Figure 12 ) and continue to the next
sprinkler.
If the type is A1000 then verify from the inside of the assembly body if
there is an internal stop valve (see Figure 13).
Pin type internal stop valve
Ball type internal stop valve (not in A1000 \
A2000 \ AB type Assembly Bodies)
Figure 13 : Internal stop valve
Log the type and existence \ absence of internal stop valve in the follow up
sheet (see Figure 12 ).
If there is NO internal stop valve, reinstall the sprinkler (go to step gbelow).
If the type is A1000 AND there IS an internal stop valve then continue:
e. Remove the 15x1,5 O-ring from the sprinkler (see Figure 14 ). Do not
damage or scratch the sprinkler’s sealing surface. Cut the removed O-Ring
to assure it does not mix with the new seals.
Note: to avoid damage to the sealing surface do not use any metal tools for
removing the O-Ring
f. Install the new 15x2,0 O-ring to the sprinkler by placing the O-ring
installation cone (see Figure 05 ) over the spindle and rolling the new O-ring
onto the sprinkler until you are sure the O-ring sits correctly in its groove
(see Figure 14 ).
g. Install the spacer to the sprinkler (see Figure 14 ).
