Spears YS-3A-0906 Instrucciones De Instalación

Installation Instructions
Read all applicable instructions & procedures thoroughly before starting.
Suitability of the intended service application must be determined prior to
installation. Plastic piping systems must be engineered, installed, operated
and maintained in accordance with accepted standards and procedures for
plastic piping systems. It is absolutely necessary that all design, installation,
operation and maintenance personnel be trained in proper handling,
installation requirements and precautions for installation and use of plastic
piping systems before starting. Y-Strainers are designed for direct in-line
installation without any adjustments.
See "Precautions and Warnings" for all installations in this instruction.

Regardless of the cutting method used, burrs will be created, which must be
removed. All pipe ends should be beveled at 10° to 15°. A deburring tool is
recommended, however a fi le may be used in its place as shown.

STEP 1
Pipe Preparation - Prepare
connecting pipes as required. Pipe ends
must be cut square at 90° using a wheel
type cutter or a saw and miter box.
Wipe away all loose dirt and moisture
from pipe end and valve socket.

CAUTION: Care must be taken to prevent primer or cement contact with
seat or internal strainer components. True Union style End Connectors
should be removed from strainer body for installation.
STEP 2
Primer Application -
Primer is necessary to penetrate
& soften both pipe and socket
connector surfaces in order for the
solvent cement to properly bond. However,
Using a brush or applicator size no
less than 1/2 the pipe diameter,
The
apply a liberal coat of primer with
a circular, scrubbing motion to the
inside socket of the Y-Strainer,
until the surface is softened and
semi-fl uid. This will occur in 5 to
15 seconds depending on size and
temperature. Apply primer to the
outside of new pipe ends in the
same manner extending application area to slightly beyond the insertion
depth of the Y-Strainer socket, or End Connector on True Union style.
APPLY A SECOND COAT TO BOTH PIPE AND SOCKET.
THE MOST FREQUENT CAUSE OF JOINT FAILURE IS INADEQUATE
PRIMER PENETRATION AND SOFTENING OF BONDING SURFACES
DURING THE WELDING OPERATION.
STEP 3
Solvent Cement End Connection -
Solvent Cement must be applied IMMEDIATELY
to the primed surfaces before the primer dries,
in an alternating 3-coat application. Using a
brush or applicator no less than 1/2 the pipe
diameter, apply a liberal coat of solvent cement
to the primed pipe surfaces. Next, apply a light
to medium coat to the primed socket surface,
then apply an additional liberal coat again to
the pipe.
Allow joint to cure
according to solvent
cement manufacturer's
instructions.
Check the penetration and softening by scraping
the primed surfaces. A few thousandths of the
semi-fl uid surface should easily be removed.
REPEAT PRIMER APPLICATION
IF NECESSARY.
STEP 4
Immediately following the
application of solvent cement, and
before it begins to set, insert the pipe
end into the Y-Strainer 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-Strainer.
