ADJUSTABLE SPRINKLER ADAPTER
INSTALLATION INSTRUCTIONS
1.
The Victaulic-supplied Spears
®
CPVC adjustable sprinkler adapter
is pre-assembled. Lubrication is not required.
1a.
Victaulic recommends adjusting the sprinkler adapter out complete-
ly before installation occurs. DO NOT over-extend the adjustment barrel.
Extend the adjustment barrel only to the point when free movement stops
or damage to internal sealing components may result.
2.
The adjustable sprinkler adapter must be installed in accordance
with the “Solvent Cementing Procedures” outlined in this manual.
2a.
Victaulic recommends solvent cementing the drop/riser pipe into
the adjustable sprinkler adapter first. Then, the drop/riser pipe can be
solvent cemented into the drop/riser tee or elbow.
2b.
Care must be taken to prevent solvent cement from contacting the
internal o-ring seal or the sealing surface of the adjustable sprinkler
adapter.
3.
The adjustable sprinkler adapter contains multiple wrench flats for
support of the adjustment barrel during sprinkler installation. In addition,
these wrench flats must be used when adjusting the sprinkler adapter to
the required position.
3a.
DO NOT use wrenches, pliers, or any other tool on the threaded por-
tion of the adjustment barrel. DO NOT over-extend the adjustment barrel.
3b.
The maximum travel range of the adjustment barrel is 1
1
/
4
inches.
Always use the wrench flats for making adjustments. Make adjustments
slowly to avoid over-extending the adjustment barrel, especially if the sys-
tem is pressurized. DO NOT extend or retract the adjustment barrel exces-
sively, since damage can result to the adapter. Adjust the barrel only to
the point when free movement stops.
4.
Sprinklers must be installed in accordance with the “Threaded Con-
nections” section of this manual. Use only thread sealants that have been
tested and approved for use with Victaulic FireLock CPVC Sprinkler Sys-
tem Products.
5.
For the purpose of hydraulic calculations,
3
/
4
-inch and 1-inch
adjustable sprinkler adapters have an average, equivalent pipe length of
3
/
4
-foot.
CAUTION
• DO NOT over-extend the adjustable barrel.
• DO NOT allow solvent cement to contact the internal o-ring seal or the sealing
surface of the adjustable sprinkler adapter.
Failure to follow these instructions could cause damage to the internal sealing
components, resulting in joint failure and property damage.
