Do not trim the paddle. Failure to follow these instructions may prevent the
device from operating and will void the warranty.
Installation (see Fig. 1)
These devices may be mounted on horizontal or vertical pipe. On horizontal pipe they shall be installed on the top side of the pipe where they
will be accessible. The device should not be installed within 6" (15 cm) of a fitting which changes the direction of the waterflow or within 24"
(60 cm) of a valve or drain.
NOTE: Do not leave cover off for an extended period of time.
Drain the system and drill a hole in the pipe using a hole saw in a slow speed drill (see Fig. 1). Clean the inside pipe of all growth or other
material for a distance equal to the pipe diameter on either side of the hole. Roll the vane so that it may be inserted into the hole; do not bend
or crease it. Insert the vane so that the arrow on the saddle points in the direction of the waterflow. Take care not to damage the non-corrosive
bushing in the saddle. The bushing should fit inside the hole in the pipe. Install the saddle strap and tighten nuts alternately to required torque
(see the chart in Fig. 1). The vane must not rub the inside of the pipe or bind in any way.

Retard Adjustment
The delay can be adjusted by rotating the retard adjustment knob from
0 to the max setting (60-90 seconds). The time delay should be set at
the minimum required to prevent false alarms
(Flowing water activates
