243 ● Never stroke the component to insert it. Doing so may cause the pipe to break. ● When using adhesive, ventilate the area well and avoid using fire nearby. Do not inhale the fume directly. ● If the adhesive contacts the skin, remove it immediately. If you feel sick or sense that something is wrong with your body, immediately seek medical attention and receive appropriate treatment. ● For adhesive, use only AV adhesive. (For U-PVC products, use adhesive No. 32, No. 52 or No. 62. For C-PVC products, use adhesive No. 88.) ● Before performing a water flow test, wait until at least 24 hours have passed since the completion of bonding. 5) Notes for threaded connection ● Check that joint screws are made of resin. (If a metal screw is used for piping work, the end connector may be damaged.) ● For threaded joints of our resin pipe, use sealing tape. If fluid seal or liquid gasket is used, a stress crack (environmental stress crack) may occur. ● Do not over-tighten joint screws. (Doing so may cause breakage.) * For notes for socket (fusion) connection, refer to the instruction manual of each product. For details, please contact our nearest distribution agent or sales office. Squeeze 4. Notes for operation and maintenance ● Do not open or close the valve when there is dust or foreign object in the fluid. ● Perform periodic maintenance. (Temperature changes or aging during long-term storage, operation stop or while in use may cause leakage. For inspection items, refer to the instruction manual of each product. For details, please contact our nearest distribution agent or sales office.) ● Before replacement of valve or parts, completely remove the fluid from the pipe. If the fluid cannot be removed, reduce the fluid pressure to zero. ● The valve body may be damaged due to freezing. In environments where freezing may occur, remove the water in the pipe or take anti-freezing measures using lagging materials. ● Move the valve handle and lever slowly to reduce water hammer. ● When disposing of the valve, always hand it over to a professional waste disposal company.
