Description

The RD13 Riser (with NPT connectors) is constructed from Listed CPVC products suitable for fire sprinkler services subject to the limitations and installation requirements of Flame guard® CPVC pipe and Spears® CPVC fittings.
The RD13 Riser incorporates a connection for a VSR-SG flow switch, gauge, and drain/test valve.
The connection for the VSR-SG flow switch is capped with a union connection to facilitate the installation and removal of the switch in confined spaces at a later date.

Installation

Using appropriate sealant, thread the female adapter on to the main water supply.
Then glue the riser assembly to the female adapter.
Pipe the drain connection to an adequate drain location capable of handling the drain discharge.
The riser can be mounted in the horizontal or vertical position.
The waterflow switch connection must be located on the top or on the side of the pipe when installed in the horizontal position.
This will prevent debris from entering the throat of the waterflow switch which could interfere with proper operation.
Following CPVC manufacturer’s instructions for preparation and gluing of CPVC piping systems, glue the main riser to the main supply line for the sprinkler heads.
Note: All glued connections must be completed and cured before the flow switch is installed.
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.
