Notes:

  1. When using a pressure switch, please specify pressure range, desired set point, and increasing or decreasing for switch contact.
  2. Use flange gaskets suitable for the system temperature and fluid media.
  3. Gauge and instruments can be removed from unit only while at zero line pressure to prevent permanent displacement of sensing fluid.
  4. 1" and 1-1/2" sizes are full 150 lb. flanged spool type; 300 lb. flanged or NPT threaded units are available. Spool type units do not have an integral isolation valve.
  5. Gauge and pressure switch shown above are optional.
  6. For full product specifications and installation instructions, see SPEC 5500-1 and ININ 5500-1, respectively.
