UL CUL Listed for use on steel pipe schedules 10 through 40 See Information chart VSR CR 10 may also be used as a sectional waterflow detector large systems The VSR CR 10 contains two single pole double snap action switches and an adjustable instantly recycling retard The switches are actuated when a flow of 10 38 LPM or more occurs downstream of the device The flow must exist for a period of time necessary to overcome the retard period Electric Signal Company LLC St Louis MO phone 866 956 1211 Canada 888 882 1833 www pottersignal com page 1 OF 4 REV A1 20vsr Cr 10 COrrOsION rEsIsTANT vANE

otherwise prevent the trip stem of the flow switch from moving when water flows as this could damage the 1 see Fig 1 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 be accessible The device should not be installed within 6 15 mm of a fitting which changes the direction of the waterflow or within 60 mm of a valve or drain Do not leave cover off for an extended period of time 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 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 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 in the saddle The bushing should fit inside the hole in the pipe Install the saddle strap and tighten nuts alternately to required torque the chart in Fig 1 The vane must not rub the inside of the pipe or bind in any way not trim the paddle Failure to follow these instructions may prevent the device from operating and

switches one can be used to operate a station proprietary or remote signaling unit while the other is used to operate a local audible or visual annunciator For supervised circuits see Terminal Connections and warning note Fig 4 uninsulated section of a single conductor should not be looped the terminal and serve as two separate connections The must be severed thereby providing supervision
