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 con-
cerning 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.
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 suscepti-
ble 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.
* Note:
The gallons per foot column can be used for calculations when adding GLYCERIN to
the piping system for freeze protection. All fire protection systems winterized with glycerin
solutions must conform to local, state, and NFPA requirements. Glycerin based solutions are
the only antifreeze solutions recommended for use. Glycol solutions are not chemically com-
patible with the CPVC material, and their use may result in damage to the Victaulic FireLock
CPVC Sprinkler System.
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.
