(E)POTTER <br />The Symbol of Protection <br />The RD13 Riser (with NPT connectors) is constructed from Listed CPVC <br />products suitable for fire sprinkler services subject to the limitations and <br />installation requirements of Flameguard® CPVC pipe and Spears® CPVC <br />fittings. The RD13 Riser incorporates a VSR-SG flow switch, gauge, and drain/ <br />test valve. The VSR-SG flow switch is equipped with union connection to <br />facilitate the installation and removal of the switch in confined spaces. <br />Installation <br />1. Using appropriate fittings connect the main water supply to the bottom of <br />the riser and the drain connection to an adecquate drain location capable of <br />handling the drain discharge. The riser can be mounted in the horizontal or <br />vertical position. Direction of flow is indicated in Fig. 1. The waterflow switch <br />must be located on the top or on the side of the pipe when installed in the <br />horizontal position. This will prevent debris from entering the throat of the <br />waterflow switch which could interfere with proper operation. The 1" NPT <br />adaptor coupling is shipped loose and may be used to ease installation. <br />2. Following CPVC manufacturer's instructions for preparation and gluing of <br />CPVC piping systems, glue the main riser to the main supply line for the <br />sprinkler heads. <br />Note: All glued connections must be completed and cured before the <br />flowswitch is installed. <br />Threaded Connections <br />3. A thread sealant shall be used in making threaded connections. Teflon® <br />thread tape is the recommended sealant. Some thread sealants other than <br />Teflon thread tape contain solvents or other materials that may be damaging <br />to CPVC. For other types of thread sealants, which have been specifically <br />investigated and confirmed to be "System Compatible", refer to www. <br />spearsmfg.com. Attach gauge to riser. Apply Teflon® tape to male fitting of <br />gauge only. See Fig 1. <br />4. Check to make sure the proper paddle is installed on the switch. (Paddle size <br />must match the riser pipe size and Tee manufacture.) <br />5. Install the flow switch to the RD 13 Riser. Verify that the o-ring is properly <br />positioned in its groove. Hand tighten the nut to the union after orienting <br />A CAUTION <br />Do not over -tighten the union nut, hand tighten only. Use of a wrench may <br />cause damage to the union nut. <br />RD 13 RISER <br />v ax-au apecmcauons: <br />UL, CUL, CSFM listed, and CE Marked <br />Service Pressure: 175 PSI (12,07 BAR) - UL <br />Flow Sensitivity Range for Signal: 4-10 GPM (15-38 LPM) - UL <br />Maximum Surge: 18 FPS (5.5 MPS) <br />Contact Ratings: Two sets of SPDT (Form C) <br />10.0 Amps at 125/250V AC <br />2.0 Amps at 30V DC Resistive <br />10 in Amps min. at 24V DC <br />Conduit Entrances: Two knockouts provided for 1/2" conduit. <br />Environmental Specifications: <br />Temperature range: 40°F - 120°F (4.5°C - 49°C) - UL <br />Replacement VSR-SG: Stock number 1144460 <br />Service Use: <br />Automatic Sprinkler NFPA-13 <br />One or two family dwelling NFPA-13D <br />Residential occupancy up to four stories NFPA-13R <br />National Fire Alarm Code NFPA-72 <br />British Standard BS9251 <br />Optional: Cover Tamper Switch Kit, stock number 0090148 <br />Replaceable Components: Retard/Switch Assembly, stock number 1029030 <br />Gauge and flow switch shipped loose in box. <br />Models: <br />1" RD13 Riser PN 1119067 <br />1 1/4" RD13 Riser PN 1119077 <br />1 1/2" RD13 Riser PN 1119087 <br />2" RD13 Riser PN 1119097 <br />• Installation must be performed by qualified personnel and in accordance <br />with all national and local codes and ordinances. <br />• Shock hazard.

Serious injury or <br />death could result. <br />the flow switch in the appropriate direction to detect waterflow. The paddle <br />must not rub the inside of the Tee or bind in any way. The stem should move <br />freely when operated by hand. See Fig. 1. Note: Do not leave switch cover <br />off for an extended period of time. <br />Orientation <br />6. Side of flow switch must be perpendicular with the riser piping. See Fig. 3. <br />Inspection and Testing <br />The frequency of inspection and testing for the Model VSR-SG and its <br />associated protective monitoring system, should be in accordance with <br />applicable Codes and Standards and/or the authority having jurisdiction <br />(manufacturer recommends quarterly or more frequently.) If provided, the <br />inspector's test valve (usually located at the end of the most remote branch <br />line) should be used for test purposes. If there is no remote inspection test <br />connection; a short length of hose may be connected to the discharge of the <br />1" drain line valve, or if the drain line is connected to a drain such as a slop <br />sink or storm drain that will sufficiently handle the discharge of the main <br />drain valve. The drain valve can be used to testthe operation of the VSR-SG <br />switch. A minimum flow of 10 GPM (38 LPM) is required to activate this <br />switch. An orifice equal to the smallest sprinkler head orifice used in the <br />system shall be attached to the drain line for testing purposes. <br />Maintenance <br />The VSR-SG waterflow switch should provide years of trouble -free <br />service. The retard and switch assembly are easily field replaceable. In the <br />unlikely event that either component does not perform properly, please order <br />replacement retard switch assembly stock number 1029030. There is no <br />maintenance required, only periodic testing and inspection. <br />Potter Electric Signal Company, LLC • St. Louis, MO • Cust Service: 866-572-3005 • Tech Support: 866-956-0988 • Canada 888-882-1833 • www.pottersignal.com <br />PRINTED IN USA MFG. #5401152 - REV J PAGE 1 OF 2 <br />02/12 <br />
