P POTTER RD 13 The Symbol of Protection Residential Riser Installation (Continued) 3. A thread sealant shall be used in making threaded connections. Teflon®thread tape is the recommended sealant. Some thread sealants other than Teflon thread tape contain solvents or other materials that may be damaging to CPVC.For other types of thread sealants,which have been specifically investigated and confirmed to be"System Compatible",refer to www.spearsmfg.com.Attach gauge to riser.Apply Teflon®tape to male fitting of gauge only.See Fig 1. 4. Check to make sure the proper paddle is installed on the switch. (Paddle size must match the riser pipe size and Tee manufacture.) 5. Install the flow switch to the RD13 Riser.Verify that the o-ring is properly positioned in its groove.Hand tighten the nut to the union after orienting the flow switch in the appropriate direction to detect waterflow.The paddle must not rub the inside of the Tee or bind in any way.The stem should move freely when operated by hand.See Fig. 1.NOTE:Do not leave switch cover off for an extended period of time. 6. The side of flow switch must be perpendicular with the riser piping.See Fig.3. Testing The frequency of inspection and testing for the Model VSR-SG and its associated protective monitoring system,should be in accordance with applicable Codes and Standards and/or the authority having jurisdiction(manufacturer recommends quarterly or more frequently.) If provided,the inspector's test valve(usually located at the end of the most remote branch line)should be used for test purposes.If there is no remote inspection test connection; a short length of hose may be connected to the discharge of the 1"drain line valve,or if the drain line is connected to a drain such as a slop sink or storm drain that will sufficiently handle the discharge of the main drain valve.The drain valve can be used to test the operation of the VSR-SG switch. A minimum flow of 10 GPM(38 LPM)is required to activate this switch.An orifice equal to the smallest sprinkler head orifice used in the system shall be attached to the drain line for testing purposes. Maintenance The VSR-SG waterflow switch should provide years of trouble-free service. The retard and switch assembly are easily field replaceable. In the unlikely event that either component does not perform properly,please order replacement retard switch assembly stock number 1029030.There is no maintenance required,only periodic testing and inspection.. Removal • To prevent accidental water damage.all control valves should be shut tight and the system completely drained before waterflow detectors are removed or replaced. • Turn off electrical power to the detector,then disconnect wiring. • Loosen nut on union fitting. • Lift detector clear of pipe.
