Spears Y-Check Instrucciones De Instalación página 2

Allow joint to cure according to solvent cement manufacturer's instructions.
STEP 5 Attach Valve Body to
End Connector Socket and begin to
tighten Union Nut.
DO NOT USE ANY TYPE OF THREAD SEALANT. "HAND TIGHTEN
ONLY."
Be sure that the face of the end connector socket is squarely aligned (fl ush)
with the valve body and is fl ush against the O-ring.
Attach fi nal Union Nut to Valve Body.
DO NOT USE THE REMAINING UNION NUT TO DRAW TOGETHER ANY
GAPS BETWEEN THE END CONNECTOR AND THE VALVE BODY.
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.
Spears Manufacturing Company highly recommends the use of Spears
®
BLUE 75™ thread sealant, which has been tested for compatibility with
Spears products.

STEP 1
- Apply Joint Sealant
- Threaded connections require
application of a quality grade thread
sealant to seal and lubricate the joint
assembly. Sealants must only be
applied to male pipe threads.
Please follow the sealant Manufacturers' Application/Installation instructions.
Choice of another appropriate thread sealant is at the discretion of the
installer.
STEP 4 Immediately following the
application of solvent cement, and
before it begins to set, insert the pipe
end into the Y-Check Valve socket,
push with a 1/4 twisting motion to
evenly distribute the solvent cement
within the joint. A full bead of solvent
cement should form around the
circumference of the joint. Hold joint
together for approximately 30 seconds
to make sure that the pipe does not
back off of socket. Use a cloth to
remove any excess cement from the
exterior juncture. Assemble other pipe
into the Y-Check Valve.

STEP 3 Wrench
Up - Threaded pipe and valve
components must always be installed
using commercially available strap
wrenches. Do not use conventional
pipe wrenches, which can cause
damage to plastic piping materials.
Apply wrench make-up of no more
than 1 to 2 turns beyond fi nger-tight
thread engagement. Care must
be taken in fi nal positioning so as
to avoid the need to "Back-up" the
wrench assembly.
Once a fl ange is attached to the pipe or valve, the method of joining two
fl anges are as follows:
STEP 1 Use of well lubricated
bolts & fl at washers are required.
Use an anti-seize lubricant, such as
IMS Copper Flake.
STEP 2 With a 1/8" gasket having a shore "A" durometer of approximately
60 in place, align the bolt holes of the mating fl anges by rotating the ring into
position. Insert all bolts, washers, and nuts. Tighten the nuts by hand until
they are snug.
®
AT THIS TIME, BE SURE THAT THE FLANGE AND GASKET SURFACES
ARE FLUSH AND SQUARELY ALIGNED.
SPECIAL SPLIT RING FLANGE INSTRUCTIONS FOR 3" & 4" Y-CHECK VALVES
DO NOT USE BOLTS TO BRING TOGETHER IMPROPERLY
STEP 2 Assemble Joint - 1 to 2
turns beyond "FINGER TIGHT" are
generally all that is required to make a
sound plastic threaded connection.
Unnecessary OVER TIGHTENING
will cause damage to both pipe and Y-
Check Valve socket.

FLANGED CONNECTIONS
Place rings as shown over the fl ange
hubs at each end of the valve body.
Insert new bolts, washers and nuts
into new pipe system fl anges, through
gasket and into the split ring fl ange in
alignment. Continue to instruction 3.
