This connector should not be disassembled for cleaning on a daily basis.
When replacing a hose or disassembling a joint, wait until the joint is cooled down to
the room temperature. If not, you may get burned or the joint may get damaged.
When cutting a hose, please make sure that the edge face of the hose will become square-on.
If there are any loose strings or hard wires coming out from the end of the hose, be sure to remove suchwith nippers, etc. Take care such that the hose scraps, loose strings, or hard wires do not enter the hose.
Be sure to have a sufficient hose length so as not to apply a hose bending stress around a coupling.
Make sure that the hose is inserted completely into the root of the hose insertion part.
Warning When inserting hoses into TOYOCONNECTOR, never put grease on the surface of thehose insertion part. It would be a cause of hose being pulled out.
Fasten the clamp after confirming the direction of each component.
Be careful of injuries caused by tools slipping during the fastening process.
Be sure to use a " hex wrench " that is at least 180mm long to fasten the bolts ( at least 200mm long for
TC6-CS50 ). Fasten the 2 bolts evenly while alternating and fasten these until there are no gaps.
When used in a state where there are gaps, trouble due to leaked fluids and detached hoses will occur.
Refrain from using an impact driver when fastening the bolts. Doing so may damage the screws of the clamp.
Note Complete fastening cannot be achieved with uneven fastening.
A lubricant ( Extreme pressure grease ) registered with NSF " H1 " " approved for use in areas that
may accidentally come into contact with food " is applied to the screw portion of the clamp of TC6-CS.
Note When fastening the unit, there rarely may be cases when resin or metal dust ( or stringy shavings )is generated. Be sure to remove such prior to use.
Avoid adhering incompatible chemicals to rubber parts of coupler.

Notes for Connector Reuse and Hose Replacement1. TOYOCONNECTOR is a coupling dedicated for TOYOX HOSE. TOYOX is not liable for any damages
caused by using TOYOCONNECTOR with any other hose including those produced by TOYOX as wellas those by other manufactures as full performance may not be achieved or maintained.
※ Hose compatibility depends on the connector.Confirm through the catalog or the homepage.
2. Use TOYOCONNECTOR with in the operating temperature and pressure ranges of the applicable hose.
3. Hoses usable under negative pressures may not be applicable depending on applications andconditions ( temperature, movement, etc. ).
4. Do not use a hose that is extremely bent near a connector. The bend radius of a hose should be larger
than its minimum bend radius.
5.
Warning Do not assemble or disassemble the connector while fluid is in the hose because thehose may become loose and the liquid will leak.
6. Do not use the hose where there is vibration or shock. It may cause the connector to break or the hose
to become detached.
7. Perform a start-up inspection and routine inspections thereafter to ensure that the hose has not comeaway from the joint, no fluid is leaking, and the bolt is tight while in use.
8. Do not allow anything other than the inner surface of the couplings or hose to come in contact with fluids,
because the fluids may permeate the hose reinforcement layer or remain inside the couplings,
and bacteria may propagate (attach to the parts) or the hose may deteriorate. Also, dust, hose fragments(reinforcement material) and ink adhering to the outer surface may be mixed in.
9.
Warning Never use TC6-CS for the below applications. Hoses may rupture or become loose.
・ For piping such as electromagnetic valve piping, which would put impact pressure on the piping
・ Where vibration or impact will be applied to the connector
・ Purposes that exceed the maximum temperature of use
・ Where constant tensile stress may be applied to the hoses
・ In a way that may cause static buildup ( There is a danger of electrical shocks. )10. Before using TC6-CS make certain to sterilize and disinfect inside the hoses.
( The hoses do not go through sterilization procedures before shipping. )11. When cleaning TC6-CS, do not rub their surfaces with a hard brush or other things because doing so may
damage the surfaces, and bacteria may propagate ( attach to the parts ). Be sure to remove such prior to use.
12. Please store the hose at low temperature and humidity. Ensure the connector is sealed for protection
against dust and foreign matter.
13. Products should be disposed of in accordance with the requirements of the local region.
14. Use dust plugs and dust caps to prevent accumulating dust and damage or deformation of the sealing surface.
15. Remove residual fluid from the main unit after using the fittings.

Notes for gaskets

2. Fix the nipple onto the pipe to which it will be attached.
Next, while adjusting the length of the hose, cut the endof the hose vertically.
Take care such that the tensile element of the hose is
not applied.

Groove1. Select the main unit and gasket materials suitable for the fluid used.
2. Chemicals which are dangerous when permeating ( active gases ) should not be used in gaseous form.
3. Do not apply external force ( e.g. impact ) to the body and cam arm. This may cause damage.
4. Avoid pulling or dragging the hoses on the floor. Doing so may cause the cam arms to catch against anobject and unlock.
5. Avoid applying loads on joints. This may cause fluid spills.
6. We recommend using couplers and adapters made of the same material when connecting fittings.
Using couplers and adapters made of different materials may lea to corrosion ( electrical corrosion ).
7. Dismantle the coupler connection only after confirming that there is no residual pressure or materials.
8. To avoid burns during use with high-temperature fluids, avoid direct contact with the fitting main unit.
9. Wear gloves and safety shoes to prevent injury during installation and operation.
10. Position the coupler on the lower side when installing fittings.
11. High fluid flow rates may result in cavitation that abrades or damages the inner surface of the coupler.
Perform inspections at the appropriate intervals.
12. When connecting coupler, chip dust may transpire due to cam arm tightening.
Remove chip dust before use.

How to attach a hose

1. When reusing a TOYOCONNECTOR product, make sure that each of its components are not damaged prior to use.
Be sure to replace the rubber cap. Please be sure to fasten the bolts after applying a commercially available lubricant( Extreme pressure grease ) to the screw portions of the bolts and the clamp. Use of a lubricant( Extreme pressure grease ) registered with NSF " H1 " " approved for use in areas that may accidentallycome into contact with food " is recommended.
2. Before replacing a hose, always make sure to remove the fluid and dirt on the connector surface.
Fluid and dirt remaining on connector may possibly cause fluid leakage and hose loosening.
3. Please make sure to use a brand-new hose.
4. Although this may differ depending on conditions of use, replace the unit with components or a new clamp set after it has
been removed approximately 5 times.
5. Do not hit the joint with a hammer or some other tools.

Warning
1. The material used for the TOYOCONNECTOR flow pass ( inner surface ) is SCS16 ( SUS316L equivalent ) .
Phenomena such as corrosion or fluid leaks may occur depending on the type of fluid. Before use, be sure tocheck data ( refer to data on chemical resistance in the catalog or on the homepage ) or makeinquiries to the toll-free number. Please also make similar checks for fluid contact with the outer surface of joints.
2. Do not use hoses when they are twisted. Partially twisted hoses are also a danger as they may cause internal
structural damage leading to a " Burst ". Follow the examples below to take preventative measures.

Example 1 ) Twisted hose while piping

Example 2 ) Twist when bent

1. Before using the coupler, check to confirm that the gasket
fits into the groove of the coupler main unit. ( See figure to the right )2. Foreign matter adhering to the gasket seat can make it hard to closethe cam arms and may lead to spills. Inspect and remove any foreignmatter.
Gasket3. Because fluorine resin type gaskets using fluorine resin ( PTFE and FEP )lack elasticity, they may leak depending on conditions of use.
4. Assess the force required to close the cam arms when connecting or disconnecting Coupler.
If the force required is too low, the gasket seal may be compromised. In this case,
we recommend replacing the gasket.
※ If closing the cam arms feels too easy even after replacing the gasket, the main unit may bedamaged. If so, replace the main unit.

Notes for inspections
1. Startup inspections: Before starting operations, check to confirm that the fittings are free ofabnormalities and that the cam arms are fully closed.
2. Regular inspection: During periods in use, be sure to perform regular inspections.

What to do if an abnormality is foundIf you observe signs of abnormalities like those below during startup inspections or periodic
inspections, stop using the product immediately. Replace with a new product.

1. The main unit or any of the components show large scratches, cracks, deformation,or projecting pins. ( The service life of the main unit, cam arms, and gaskets depends onmaterials and usage conditions. We recommend replacement at periodic intervals. )2. Closing the cam arms feels too easy when connecting or disconnecting Coupler.
