(E) POTTER VS R The Symbol of Protection Vane Type Waterflow Alarm Switch W/Retard 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. A CAUTION Do not trim the paddle.Failure to follow these instructions may prevent the device from operating and will void the warranty.Do not obstruct or otherwise prevent the trip stem of the flow switch from moving when water flows as this could damage the flow switch and prevent an alarm.If an alarm is not desired,a qualified technician should disable the alarms stem.
