On horizontat pipe they shall be installed on the top side of the pipe where they <br /> will be accessible. The device should not be installed within 6"(15 cm)of a fitting which changes the direction of the:waterfiow or within 24" <br /> (60 cm)of a valve or drain. <br /> NOTE:Do not leave cover ofl'for an extended period of time. <br /> 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 <br /> 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 <br /> or crease it. Insert the vane so that the arrow on the saddle points in the d'uection of the waterRow.Take caze not to damage the non-corrosive <br /> 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 <br /> (see the chart in Fig. 1).The vane must not rub the inside of the pipe or bind in any way. <br /> � cAUTioN <br /> Do not trim the paddle.Failure to follow these instructions may prevent the <br /> device from o eratin and will void the warran <br /> Fig.1 Retard Adjustment <br /> DO NOT LE,'AV�'C04 EX OFF'F'OR <br /> .s,v�ENVE�Y�;tuoD oF�rLUt The delay can be adjusted by rotating the retard adjustment knob from <br /> 0 to the max setting(60-90 seconds).The time delay should be set at <br /> the minimum required to prevent false alarms <br /> . <br /> TIGHTEN NUTS <br /> �/�.��,A�LY �p�'ION <br /> ole must be drilled perpendicular to the pipe and vertically centered <br /> o � efer to the Compatible Pipe/Installation Requirements chart for size. <br /> Correct Incorrect <br /> MOUNT ON PIPE SO -O <br /> I ARROW ON SADDLE - � <br /> POINTS IN DIRECTION <br /> OF WATERFLOW <br /> � <br /> ROLL PADDLE IN somm <br /> DIltECTION OF OPPOSITE DIRECTION ��TeR qDpp7Ee <br /> OF WATERFLOW <br /> WATERFLOW I � � <br /> ` \ (Flowmg Hater actrvales 2001"�°'Q1�. <br /> � device in one drrectron onlv.} DN50ONLY <br /> USE(2)S180162 ADAPTERS AS SHON/N ABOVF <br /> Dy4 dI6-Il <br /> UWGq IIAbiF <br /> Compatible Pipe/Installation Requirements <br /> Model Noailnal Pipe Nominal Pipe Pipe Wall Thickness Hole Size U-Bolt Nuts <br /> Size O.D Sc6edule 10(UL) Schedule 40(UL) BS-1387(LPC) DN(VDS) Torque <br /> inch mm inch mm inch mm iach mm inch mm inch mm inch mm ft-(b n-m <br /> VSR-2 2 DN50 2.375 60.3 0.109 2.77 0.154 3.91 0.142 3.6 0.091 23 <br /> VSR-2 U2 2.5 - 2.875 73.0 0.120 3.05 0.203 5 16 - - - - 125+.125/-.062 33.Ot2.0 <br /> VSR-21/2 - DN65 3.000 76.1 - - - - 0.142 3.6 0.102 2.6 <br /> VSR-3 3 DN80 3.500 88,9 O.I20 3.05 0.216 5 49 0.157 4 0 0 114 2.9 <br /> VSR-3 1/2 3.5 - 4.000 101.6 0.120 3.05 0.226 5 74 - - _ _ z0 Z� <br /> VSR-4 4 DN100 4.500 1143 0120 3.05 0.237 6.02 0.177 4.5 0.126 32 <br /> 2.00 t 125 'i0.8 t 2.0 <br /> VSR-5 5 - 5.563 141.3 0134 3.40 0258 6.55 - - _ _ <br /> VSR-6 6 DN150 6.625 168.3 0.134 3 40 0280 7 I1 0 197 5 0 0 157 4.0 <br /> VSR-8 8 DN200 8.625 2191 0148 3.76 0.322 8.18 0.248 6.3 0.177 4.5 <br /> NOTE.For copper or plastic pipe use Model V SR-CF <br /> PRINTED IN USA MFG.#5401146-REV L PAGE 2 OF 4 <br /> 3/09 <br />
