(These chemicals may cause damage to the valve.)
Caution
General Information for Transportation, Unpacking and Storage
-Store products in their corrugated cardboard boxes. Avoid exposing products to direct sunlight, and store them
indoors (at room temperature). Also avoid storing products in areas with excessive temperatures. (Corrugated
cardboard packages become weaker as they become wet with water or other liquid. Take care in storage and
handling.)
-After unpacking the products, check that they are defect-free and meet the specications.
Inspection Items
Caution
General Operating Instructions
-Using a positive-pressure gas with our plastic piping may pose a dangerous condition due to the repellent force
particular to compressible uids even when the gas is under similar pressures used for liquids. Therefore, be sure
to take the necessary safety precautions such as covering the piping with protective material. For inquiries, please
contact us. For conducting a leak test on newly installed piping, be sure to check for leaks under water pressure.
If absolutely necessary to use a gas in testing, please consult your nearest service station beforehand.
-Be sure to conduct a safety check on all hand and power tools to be used before beginning work.
-Wear protective gloves and safety goggles as uid remain in the valve even if the pipeline is empty. (You may be injured.)
-Keep the valve away from excessive heat or re. (It can be damaged, or destroyed.)
-Always operate the valve within the pressure vs. temperature range.
(The valve can be damaged or deformed by operating beyond the allowable range.)
-Select a valve material that is compatible with the media. For chemical resistance information, refer to “CHEMICAL
RESISTANCE ON ASAHI AV VALVE”. (Some chemicals may damage incompatible valve materials.)
-Do not step on or apply excessive weight on valve. (It can be damaged.)
-When installing a pipe support by means of a U-band or something similar, take care not to over-tighten. (Excessive
force may damage the pipe.)
-Take care not to over-tighten the Union Nut. (The valve can be damaged.)
Warning
Caution
-Certain liquid such as H2O2, NaClO, etc may be prone to vaporization which may cause irregular pressure increases,
which may destroy the valve.
-Do not change or replace the Y-SEDIMENT STRAINER parts under line pressure.
Check for aw, crack, or deformation on the valve. Check for leaks to the outside or inside.
Inspect the cap nut and be sure it is not loose. Check for clogged or blocked screen.

-Allow sufcient space for maintenance and inspection.
-Keep the valve out of direct sunlight, water and dust. Use cover to shield
the valve. (The valve will not operate properly.)
-Install the piping in such a manner that it will not be exposed to direct
sunlight. (The body may otherwise get discolored or the screen may get
distorted, resulting in failure to function.)
-Perform periodic maintenance. (Leakage may develop due to temperature
changes or periods of prolonged storage, rest, or operation.)
-When installing pipes and valves, ensure that they are not subjected to
tension, compression, bending, impact, or other excessive stress.
-When installing, disassembling, or reassembling the piping, x the End
Connector.
-Fasten the Union Nut while avoiding the parallelism and axial misalignment
of the ange surface.
-When connecting an ASAHI AV Valve to metal piping, take care not to let
pipe stress to ASAHI AV Valve.
-The Y-SEDIMENT STRAINER is so structured as to be vulnerable to
repeated stresses due to internal pressure changes in the corner. Damage
may therefore occur in a line subject to pulsation. (including air hammering
and water hammering)
-Use the valve at a level less than the permissible ow speed.
(The screen may otherwise get distorted or damaged.)(Scheme 1)
-Periodically clean the screen in accordance with use.
-Before a water test, be sure that the Union Nut is tightly fastened.
-Plumb in the strainer considering the uid direction (the arrow is shown on
the body) so that the screen points downward.(Fig.1)

Installation Procedure
The connection method of the SEDIMENT STRAINER, there are Flanged End, Socket End, Threaded End. Install according to
the preferred method of joining for the particular application. As for details, refer to the User's manual separately.
-Take care not to over-tighten the Union Nut. (The valve can be damaged.)
-The parallelism and axial misalignment of the ange surface should
be under the values shown in the following table to prevent damage to
the valve.（A failure to observe them can cause destruction due to stress
application to the pipe）
-Use at faced anges for connection to AV Valves.
-Ensure that the mating anges are of the same standards.
-Be sure to use sealing gaskets (AV Gasket), bolts, nuts, and washers
and tighten them to specied torques.
1. Cleaning: Conrm the ange face area is clean and free of dirt or
foreign materials.
2. Set the AV gasket between the anges. Insert washers and bolts
from the pipe side, insert washers and nuts from the valve side, then
temporarily tighten them by hand. Tighten the bolts and nuts gradually
with a torque wrench to the specied torque level in a diagonal manner.

-When using an adhesive, ventilate the space sufciently, prohibit the use of a re in the vicinity, and do not inhale
adhesive vapors directly.
-Take care in doing work at low temperatures. Solvent vapors are hard to evaporate and are likely to remain. (Solvent
cracks may occur, damaging the equipment.) After assembling the piping system, open both ends of the piping and
use a fan (of the Low-Voltage Type) or something similar to ventilate the space, thus removing the solvent vapors.
-Do not apply more cement than necessary. Avoid getting cement in the internals of the valve. This can cause damage
to the seals and moving parts. Solvent and fumes can chemically attack the valve materials if allowed to enter the
internals of the valve. (Cementing with the valve in a vertical position should be avoided)
-Do not under any circumstances try to insert a pipe into another tting or valve by striking it, which may break the
piping.
-Use Asahi AV cement Number-32, Number-52, or Number-62 for PVC in case of JIS Pipe & Fittings. The other
standard Pipe & Fittings shall be used industrial proper PVC cement.
-Allow 24 hours for solvent cement to dry before performing a water leak test.
-If an adhesive gets into contact with your skin, wash it off immediately. If you feel sick or nd any anomaly, receive a
physician's diagnosis and take appropriate measures promptly.
4. Entry of the Bench Mark: The bench mark indicates the maximum penetration
depth of the pipe into the end connector.
5. Cleaning: Clean the hub part of the end connector by wiping with a waste cloth.
6. Application of adhesive: Apply adhesive evenly to the hub part of the end
connector and the pipe spigot.
7. Insertion: After applying adhesive, insert the pipe quickly into the end connector
and leave it alone for at least 60 seconds.
8. Insertion completion: Wipe away overowing adhesive.
