The RD13 Riser incorporates a VSR-SG <br />flow switch, gauge, and drain/test valve. The VSR-SG flow switch is <br />equipped with union connection to facilitate the installation and removal <br />of the switch in confined spaces. <br />Installation <br />1. Using appropriate sealant, thread the female adapter on to the <br />main water supply. Then glue the riser assembly to the female <br />adapter. Pipe the drain connection to an adequate drain location <br />capable of handling the drain discharge. The riser can be mounted <br />in the horizontal or vertical position. Direction of flow is indicated <br />in Fig. 1. The waterflow switch must be located on the top or <br />on the side of the pipe when installed in the horizontal position. <br />This will prevent debris from entering the throat of the waterflow <br />switch which could interfere with proper operation. <br />2. Following CPVC manufacturer's instructions for preparation and <br />gluing of CPVC piping systems, glue the main riser to the main <br />supply line for the sprinkler heads. NOTE. All glued connections <br />must be completed and cured before the flowswitch is installed. <br />(Continued on page 2). <br />CAUTION <br />IDonotorcause7tto <br />on nut, hand tighten only.
