The installer shall understand the use of this product and why it was specified
for the particular application.
• The installer shall understand common industry safety standards and potential
consequences of improper product installation.
• It is the system designer’s responsibility to verify suitability of stainless steel
flexible hose for use with the intended fluid media within the piping system and
external environment.
• The material specifier shall evaluate the effect of chemical composition, pH
level, operating temperature, chloride level, oxygen level, and flow rate on
stainless steel components to confirm system life will be acceptable for the
intended service.
• It is the responsibility of the owner of a building or their authorized agent
to provide the sprinkler system installer with any knowledge that the water
supply might be contaminated with or conducive to the development of
microbiologically influenced corrosion (MIC), including as required by NFPA 13.

National Fire Protection Association (NFPA 13, 13D, 13R, etc.) standards or
equivalent standards and in accordance with applicable building and fire codes.
Victaulic®VicFlex™products are intended to be installed in wet, dry, or preaction
actuated systems. Deviations from these standards or alterations to Victaulic®
VicFlex™products or sprinklers 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.
• Victaulic® VicFlex™products shall not be intermixed with other manufacturer’s
flexible sprinkler products.
• For recessed sprinklers, a standard long elbow reducer is recommended.
• For concealed sprinklers, a short 90° elbow reducer is recommended.
• Refer to the specific Victaulic®product publication for applications and listing
information. In addition, when installing Victaulic®FireLock™Automatic
Sprinklers with Victaulic®VicFlex™Sprinkler Fittings, refer to the I-40
Installation and Maintenance Instructions for details on sprinkler installation
requirements. Product publications and installation instructions can be
downloaded at victaulic.com.
• 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.

I-VICFLEX_15GENERAL INFORMATION REV_A
• 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 or exceed the maximum listed or approved temperature ratings.
• The flexible hose shall not be bent or fluctuated up-and-down or side-to-side when
pressurized.
• Victaulic®VicFlex™flexible hoses may be painted or coated, provided that the paint
or coating is compatible with stainless steel material. Care shall be taken to ensure
that the sprinkler and associated components are not painted.
• When using recessed sprinklers, the standard long elbow reducer is recommended.
• Flexible hose and fittings have limited flexibility and are intended only to be
installed with bends not less than their respective minimum bend radii. DO NOT
install a flexible hose in a straight configuration.
• Victaulic®VicFlex™Series AH1 and AH2 Flexible Hoses can be installed for
hydrostatic testing and then readjusted for final sprinkler placement once the
ceiling structure and associated Victaulic®VicFlex™brackets are installed.
• Protect wet piping systems from freezing temperatures.
• If construction is altered, the building owner or their representative is responsible
for referencing applicable standards to determine if additional sprinklers or other
system adjustments are required.
• The building owner or their representative is responsible for maintaining the fire
protection system in proper operating condition.
• After installation is complete, the entire sprinkler system shall be tested in
accordance with applicable standards (NFPA 13, NFPA 25, etc.) that describe
the care and maintenance of sprinkler systems. In addition, the authority having
jurisdiction may have additional maintenance, testing, and inspection requirements
that shall be followed. NOTE: A successful test is not a substitute for proper system
installation and maintenance.
• Victaulic®VicFlex™flexible hoses may penetrate drywall.
