PLEASE READ THE FOLLOWING INFORMATION PRIOR TO INSTALLING AND USING HAYWARD TC SERIES
TRUE UNION BALL CHECK VALVE. FAILURE TO FOLLOW THESE INSTRUCTIONS MAY RESULT IN PRODUCT
DAMAGE, PROPERTY DAMAGE, PERSONAL INJURY, OR EVEN DEATH.
1. Hayward Flow Control (Hayward), a division of Hayward Industries, guarantees its products against defective material and workmanship only.
Hayward assumes no responsibility for property damage or personal injury resulting from improper installation, misapplication, or abuse of any
product.
2. Hayward assumes no responsibility for property damage or personal injury resulting from chemical incompatibility between its products and the
process fluids to which they are exposed. Determining whether a particular PVC, CPVC, PP, or PVDF product is suitable for an application is the
responsibility of the user. Chemical compatibility charts provided in Hayward literature are based on ambient temperatures of 70°F and are for
reference only.
3. Hayward products are designed for use with non-compressible liquids.
4. The maximum recommended fluid velocity through any Hayward product is eight feet per second (8 ft/s). Higher fluid velocity can result in damage
due to the water hammer effect.
5. Piping systems must be designed and supported to prevent excess mechanical loading on Hayward products due to system misalignment, weight,
shock, vibration, and the effects of thermal expansion and contraction.
6. The effect of temperature on plastic piping systems must be considered when the systems are initially designed. The pressure rating of plastic
systems must be reduced with increasing temperature. Maximum operating pressure is dependent upon material selection as well as operating
temperature. Before installing any Hayward product, consult Hayward product literature for pressure vs. temperature curves to determine any
operating pressure or temperature limitations.
7. PVC, CPVC, PP, and PVDF plastic products become brittle below 40°F. Use caution in their installation and operation below this temperature.
8. Due to differential thermal expansion rates between metal and plastic, transmittal of pipe vibration and pipe loading forces, DIRECT
INSTALLATION OF PLASTIC VALVES INTO METAL PIPING SYSTEMS IS NOT RECOMMENDED. Wherever installation of plastic valves into
metal piping systems is necessary, it is recommended that at least 10 pipe diameters in length of plastic pipe be installed upstream and
downstream of the plastic valve to compensate for the factors mentioned above.
9. Published operating requirements are based on testing of new valves using clean water at 70°F. Valve performance is affected by many factors
including fluid chemistry, viscosity, specific gravity, flow rate, and temperature. These should be considered when sizing Hayward products.
10. Systems should always be depressurized and drained prior to installing or maintaining any Hayward product.
11. Always follow your site and/or company procedures for any safety training and/or site specific precautions or warnings in addition to those in this
document.

WARNING
Hayward PVC, CPVC, PP, and PVDF products should NEVER be used or tested with compressible fluids such as compressed air
or nitrogen. Use of PVC, CPVC, PP, and PVDF products in compressible fluid applications may result in product damage,
property damage, personal injury, or even death.
WARNING
The TC Series True Union Ball Check Valve is intended for use in liquid service only. Do not attempt to use this valve for
controlling air or gases. Use of this product in air or gas service may result in product damage, property damage, personal
injury, or even death.
WARNING
Hayward PVC and CPVC products should not be used in services with operating temperature below 34°F.
WARNING
Failure to depressurize and drain system prior to installing or maintaining valve may result in product damage, property damage,
personal injury, or even death.
