INTRODUCTION
Victaulic FireLock CPVC Sprinkler System Products are manufactured from high-quality,
Post-Chlorinated Polyvinyl Chloride (CPVC), a specialty thermoplastic material. Victaulic
FireLock CPVC Sprinkler System Products are designed specifically for fire sprinkler
systems. They provide unique advantages over traditional sprinkler piping systems
through superior hydraulics, ease of installation and handling, and quick assembly using
readily available, inexpensive tools. In addition, Victaulic Style #899 FireLock CPVC
One-Step Solvent Cement eliminates the need for primers that are typical in two-step
cementing processes. The one-step process simplifies installation and reduces labor
time.
DANGER
Victaulic FireLock CPVC Sprinkler System Products must be used in wet systems •
only. A wet piping system contains water and is connected to a water supply
system so that the water will discharge immediately when the sprinkler activates.
Victaulic FireLock CPVC Sprinkler System Products must never be used in a •
system that uses compressed air or other gases.
Failure to follow these instructions could result in severe personal injury, significant
property damage, and product damage.
CAUTION
DO NOT use Victaulic FireLock CPVC Sprinkler System Products in outdoor •
applications. These products are not Listed for outdoor applications.
Failure to follow this instruction could result in product failure and property
damage and will not be covered under the Victaulic CPVC warranty.

Cold Temperature Areas:
Victaulic FireLock CPVC Sprinkler System Products can be used if the ambient •
temperature remains above 35°F.
In addition, these products can be used if the installation is in an area subject •
to freezing temperatures; however, the sprinkler system must be protected from
freezing. Many standard cold weather piping design and installation practices can
be used to protect the system from freezing, including, but not limited to, the use
of glycerin, insulation installation techniques, and pipe insulation. Contact Victaulic
with questions concerning compatibility. NOTE: Attention must be given to local
insulating techniques and codes that require a particular method.
Antifreeze solutions of water and USP or CP grade GLYCERIN are acceptable for use •
with Victaulic FireLock CPVC Sprinkler System Products. Refer to NFPA 13, NFPA
13R, and NFPA 13D.
WARNING
DO NOT allow a sprinkler system to freeze. A frozen system will deactivate, and •
the pressure can damage pipe or cause sprinklers to open.
DO NOT use glycol-based antifreeze solutions. Glycol solutions are not •
chemically compatible with the CPVC material and can cause damage to the
Victaulic FireLock CPVC Sprinkler System.
Failure to follow this instruction can result in serious personal injury, property
damage, and product damage.
Consult the local authority having jurisdiction before using glycerin solutions in fire
sprinkler applications. Since very cold weather will make Victaulic FireLock CPVC
Sprinkler System Products more susceptible to damage, extra care should be taken to
avoid rough handling or impact to these products.
The following information can be used to determine the quantity of an antifreeze solution
needed to protect the piping system.
