To remove a detector:
1. Drain the pipe.
2. Turn off electrical power to the detector and disconnect
the wiring.
3. Loosen the nuts and remove the U-bolts.
4. Gently lift the saddle far enough to get your fingers un-
der it. Then, roll the vane so it will fit through the hole
while continuing to lift the waterflow detector saddle.
5. Lift the detector clear of the pipe.
CAUTION
If a vane breaks in a pipe, find and remove it. If it is not re-
moved, the vane may restrict the flow of water to all or part
of the sprinkler system.
