Notes:
- When using a pressure switch, please specify pressure range, desired set point, and increasing or decreasing for switch contact.
- Use flange gaskets suitable for the system temperature and fluid media.
- Gauge and instruments can be removed from unit only while at zero line pressure to prevent permanent displacement of sensing fluid.
