Join Components - IMMEDIATELY following application of

cement and before it starts to set, insert the pipe into the valve socket
with a 1/4 - turn, twisting motion to evenly distribute cement within the
joint. Final position must place valve as designated "This Side Up." A
full bead of cement must form around the circumference of the joint. Hold
joint together for approximately 30 seconds to make sure the pipe does
not move or back out of the socket. Using a cloth, wipe clean all excess
cement from the exterior juncture of the pipe and valve.
Initial Set & Cure Time - Initial Set & Cure Time must be
STEP 6
followed in accordance with the solvent cement manufacturer's instructions.
Pressure test the system only after all solvent cement joints have fully
cured.
THREADED CONNECTIONS
WARNING: SOME PIPE JOINT COMPOUNDS OR TEFLON PASTES
MAY CONTAIN SUBSTANCES THAT COULD CAUSE STRESS
CRACKING TO PLASTIC. TRANSITIONS TO METAL PIPE REQUIRE
THOROUGH CLEANING AND DEGREASING TO REMOVE ANY PIPE
THREAD CUTTING OIL.
RECOMMENDED SEALANT: Spears
recommends the use of Spears
has been tested for compatibility with Spears
the sealant Manufacturers' Application/Installation instructions. Choice of
another appropriate thread sealant is at the discretion of the installer.
IF A TAPE SEALANT IS USED:
1. Use TFE tape no less than 2.5 mil thick.
2. Initial wrap must fully cover the thread end.
3. Wrap clockwise with standard pipe threads.
4. Use only 2-3 wraps of tape.
Apply Joint Sealant - Threaded connections require
STEP 1
application of a quality grade thread sealant to seal and lubricate the joint
assembly. Sealants must only be applied to male pipe threads.

Assemble Joint by Hand - Threaded pipe and valves must

be initially assembled "finger tight" — just enough to fully engage thread
clearance.
Wrench Make-Up
STEP 3
must always be installed using commercially available strap wrenches. Do not use
conventional pipe wrenches which can damage plastic piping materials.
Apply wrench make-up of no more than one to two turns beyond finger tight thread
engagement. Care must be taken in final positioning so as to avoid the need to
"back-OUT" (unthread) the wrenched assembly.
PRECAUTIONS AND WARNINGS
CAUTION: The system must be designed and installed so as not to pull
the components in any direction. Pipe system must be cut and installed
in such a manner as to avoid all stress loads associated with bending,
pulling, or shifting. All piping systems must be supported.
CAUTION: BEFORE THE VALVE IS CYCLED, all dirt, sand grit or other
material shall be fl ushed from the system. This is to prevent scarring of
internal components.
WARNING: System should not be operated or fl ushed out at fl ow velocities
greater than 5 feet per second.
NOT FOR USE WITH COMPRESSED AIR OR GAS
WARNING: Do not use compressed air or gas to test any PVC or CPVC
thermoplastic piping product or system, and do not use devices propelled
by compressed air or gas to clear the systems. These practices may result
in explosive fragmentation of system piping and components causing
bodily injury or death.
All air must be bled from the system during the initial fl uid fi ll. Pressure
testing of the system must not be made until all solvent cement joints have
properly cured. Initial pressure testing must be made at approximately 10%
of the system hydrostatic pressure rating to identify potential problems
prior to testing at higher pressures.
