Approved for use on steel pipe 10 through 40 sizes 50 mm thru 200 mm 2 thru 8 LPC approved sizes are 50 mm thru 200 mm 2 thru 8 See Ordering chart VSR EU may also be used as a sectional waterflow detector on large systems The VSR EU contains two single pole double throw snap switches and an adjustable instantly recycling pneumatic retard The switches are actuated when a flow of 38 LPM 10 GPM or more downstream of the device The flow condition must exist for a period of time necessary to overcome the selected retard period VSR EU switches and retard device are enclosed in a general purpose die cast housing The cover is held in place with two tamper resistant which require a special key for removal Electric Signal Company LLC St Louis MO Phone 866 956 1211 Canada 888 882 1833 www

horizontal pipe they shall be installed on the top side of the pipe where they be accessible The device should not be installed within 15 cm 6 of a fitting which changes the direction of the waterflow or within 60 24 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 will void the warranty 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 an alarm is not desired a qualified technician should disable the alarm system 1 NOT LEAVE COVER FOR AN EXTENDED OF TIME MOUNTING HOLES FOR MINIMAX CARD ADAPTER ONLY DIN 7981 M2,9 X 9,5 MM
