IMPORTANT INSTALLATION INFORMATION

• Victaulic® FireLock™ Automatic Sprinklers shall be installed according to current, applicable Factory Mutual (FM) standards, VdS standards, CEA 4001 standards, National Fire Protection Association (NFPA 13, 13D, 13R, etc.) standards or equivalent standards and by applicable building and fire codes. Deviations from these standards or alterations to sprinklers (including painting and coating) will void any Victaulic warranty and will impact system integrity. Installations shall meet the provisions of the local authority having jurisdiction and local codes, as applicable, and shall comply with all design specifications.
• Refer to the specific Victaulic product publication for applications and listing information. Product publications can be downloaded at victaulic.com.
• Transport and store sprinklers in a cool, dry environment in their original packaging. To prevent damage, DO NOT empty sprinklers into bags or buckets.
• Size the piping system to meet or exceed the minimum required flow rate for the sprinkler system.
• Per NFPA requirements, flush the system to remove foreign material. Continue to flush the system until water runs clear.
• DO NOT install sprinkler system piping through heating ducts.
• DO NOT connect sprinkler system piping to domestic hot water systems.
• DO NOT allow electrical wiring or other cabling to be hung or wrapped around the sprinkler piping system.
• DO NOT install sprinklers and sprinkler fittings where ambient conditions may fall below the minimum or exceed the maximum listed or approved temperature ratings.
• DO NOT install sprinklers that have been dropped or struck by another object, even if they do not appear damaged. Never install glass bulb sprinklers if the bulb is cracked or if there is a loss of liquid from the bulb. Discard and replace any sprinklers that are damaged or show signs of corrosion.
• Before installation, verify that the sprinkler is the proper model, orifice size, and temperature rating for the intended application.
• Protect wet piping systems from freezing temperatures.
• To avoid damage, install sprinklers into the fittings only after the sprinkler system piping is in place.
• DO NOT paint, coat, plate, or alter sprinklers. Sprinklers that have been altered from their manufactured condition may not function properly and will void any agency listings and/or approvals and impact system integrity.
• DO NOT test sprinklers with a heat source. The glass bulb can weaken or shatter if exposed to a heat source during testing.
• DO NOT clean sprinklers with soapy water, detergents, ammonia, cleaning fluids, or other chemicals. Remove any dust, lint, etc. with a soft, dry cloth.
• Sprinklers that have operated SHALL NOT be reassembled or reused. When replacing sprinklers, use new sprinklers of the same type, orifice, temperature, and response.
• Inspect sprinklers regularly for corrosion, mechanical damage, obstructions, etc. The frequency of inspections may vary due to corrosive atmospheres/water supplies and activities around the sprinklers.

• Model V41 Dry ESFR Sprinklers are designed only for wet systems.
• Where systems incorporate IGS grooves for sprinkler connection, the Style V9 Victaulic® FireLock™ IGS™ Installation-Ready™ Sprinkler Coupling shall be used.

DRY SYSTEMS:

Dry sprinklers designed for use in dry systems shall be installed only into the outlet of a fitting (excluding elbows) or welded outlet that meets the dimensional requirements of ANSI B16.3 and ANSI B16.4, Class 125 and Class 150. Use a sample fitting to confirm proper engagement and to verify that there is no interference between the sprinkler and the fitting. To ensure unobstructed flow during operation, and for applications where systems are subjected to freezing temperatures, the dry sprinkler shall be installed into a fitting that will prevent condensation from accumulating above the seal.

WET SYSTEMS:

The inlet of the dry sprinkler SHALL NOT bottom out in the fitting. DO NOT install dry sprinklers into any threaded elbow, thread-by-thread coupling, or fitting that interferes with thread penetration. Dry sprinklers can be installed into the outlets of Style 920/Style 920N Mechanical-T Bolted Branch Outlets, Style 922 FireLock™ Outlet-T products, and No. 141 IGS™ Grooved x Female Threaded Adapter Nipples. Dry Sprinklers can be installed into CPVC fittings (excluding elbows) that do not interfere with thread penetration. Use a sample fitting to confirm proper engagement. Verify that the exposed minimum barrel length in the heated space is measured and maintained in accordance with the table below. The table below is used when the ambient temperature is maintained between 40° F/4° C and 60°F/16°C around the wet piping system.
