Installation Notes

  • Flexible connections must be installed between hard piping and tank openings. Failure to install flex connections properly with the vessel will void the warranty.
  • Pressure vessels are rated for an internal negative pressure of 5" Hg (17 Pa) vacuum below atmospheric. If negative pressure could exceed 5" Hg (17 Pa), an adequate vacuum breaker must be installed.
  • Bolt base to floor.
  • Calculate height for valve and base combined.
