VSR <br /> p POTTER VANE TYPE WATERFLOW <br /> The Symbol of Protection ALARM SWITCH WITH RETARD <br /> installation (see Fig. l) <br /> 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 <br /> will be accessible. The device should not be installed within 6"(15 cm)of a fining which changes the direction of the waterfiow or within 24" <br /> (60 cm) of a valve or drain. <br /> NOTE: Do not leave cover off 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. I). 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 direction of the waterfiow. Take care not to damage the non-corrosive <br /> hushing 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. I).The vane must not rub the inside of the pipe or bind in any way. <br /> A CAUTION <br /> Do not trim the paddle.Failure to follow these instructions may prevent the <br /> device from operating and will void the warranty. <br /> Fig.1 Retard Adjustment <br /> DO NOTLE4VE COVER OFF FOR <br /> ./�` r ,I,VEXTENDED PERIOD OF TIME 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 /> ►__-2ti ��il. -4.: the minimum required to prevent false alarms <br /> _�\ ;II \' q <br /> ,4N n)011 <br /> I/ TIGHTEN NUTS <br /> _ \�� 1,h'� +II III ALTERNATELY <br /> J o&i 'J CAUTION <br /> J,...e,0 l' Hole must be drilled perpendicular to the pipe and vertically centered. <br /> ,� ''`-'" � Refer to the Compatible Pipe/Installation Requirements chart for size. <br /> ��� � Correct Incorrect <br /> .
