FIG. 5
Use the drawing at
right as a template
and cut at the dotted
arc when trimming
the appropriate
paddle for interme-
diate pipe sizes.
CAUTION:
The paddle must not
touch the inside of
the pipe or bind in
any way.

Typical paddle arrangement
for 6" to 8" pipe, using smaller
flexible paddles for added

ity.
NOTE:
When installing rigid
paddles, do not
stack paddles. Only
install ONE paddle
that best fits the pipe.
