IntroductionThis document provides installation, operation, and maintenance instructions for Hayward Y-Strainers. It emphasizes the importance of following these guidelines to prevent injury and ensure proper product performance.
Product Guarantee and ResponsibilityHayward guarantees its products against defects in material and workmanship but does not assume responsibility for damages or injuries due to improper installation, misuse, or chemical incompatibility. Users should verify compatibility and suitability for their specific applications.
Operating ConditionsBefore installation, consult Hayward literature for pressure and temperature limitations. The maximum fluid velocity is eight feet per second to avoid damage from water hammer effects. Hayward products are designed for non-compressible liquids and should not be used with compressible fluids.
Installation ConsiderationsSystems must be depressurized and drained before installation or maintenance. Consider temperature effects on piping systems to prevent mechanical loading on equipment. Avoid direct installation of metal pipes into plastic connections; use at least 10 pipe diameters of plastic pipe upstream and downstream of plastic
valves.
Socket ConnectionSocket connections should follow ASTM specifications. Proper cleaning, priming, and cementing techniques are essential to ensure leak-free joints. Full set and cure times vary based on temperature and pipe size.
Threaded ConnectionThreaded connections require Teflon tape for sealing. Pipes should be hand-tightened and then further tightened with a strap wrench to avoid excessive stress.
Flanged ConnectionFlange bolts should be tightened to compress the gasket without distorting the flanges. Use a cross-sequence tightening method and well-lubricated bolts and nuts.
Installation RecommendationsInstall strainers at least 10 pipe diameters from
pumps and 5 diameters from elbows. Maintain a maximum fluid velocity of 8 feet per second.
Screen CleaningDepressurize and drain the system before cleaning the strainer screen. Clean the screen when the pressure drop exceeds 5 PSI. Avoid deforming the screen during cleaning and use non-petroleum lubricants for reassembly.
ConclusionFollowing these guidelines ensures the safe and efficient operation of Hayward Y-Strainers. Regular maintenance and adherence to installation procedures are crucial for optimal performance.
