Installation
The installation instructions for the
TYCO CPVC Hanger Head Set Model
SHB1 for different types of wood joist
are defined in the following sections:
• Hanger Head Set — Solid Wood
Joist
• Hanger Head Set — Composite
Wood Joist
NOTICE
The TYCO CPVC Hanger Head Set
Model SHB1 does not meet the UL
requirement for providing vertical
restraint that may result from a sprin-
kler activation. A number of hanger
techniques (not inclusive of the use
of a Hanger Head Set) as described
in Installation Handbook IH-1900 can
be used to provide vertical restraint.
Failure to provide vertical restraint may
result in vertical lift upon sprinkler acti-
vation and the inability of a sprinkler to
spray effectively in the event of a fire.
Installing sprinklers into the sprin-
kler adapter fittings prior to solvent
cementing the adapters to the drop is
unacceptable. Failure to allow sprin-
kler fitting joint to cure before install-
ing sprinklers may result in cement in
sprinkler waterway and inability of the
sprinkler to properly operate in the
event of a fire.
The hanger head set should not be
installed other than side-mount or
attached to anything other than the
side of a solid wood framing member
or structural composite wood joist, with
the fasteners provided, without prior
review and approval of the authority
having jurisdiction. Any other method
of installation may not comply with
NFPA or local requirements. If the
installer attaches the Hanger Head Set
to another type of structural member or
orients the Hanger Head Set in a posi-
tion other than side-mount, fasteners
and fastener methods shall comply
with applicable NFPA and local code
requirements.
