1. Pressure ranges are based on the spring case pointing up. Pointing the spring case down increases the pressure range 1.7-inches w.c. (4 mbar).
(Example: 1 to 3-inches w.c. (2 to 7 mbar) changes to 2.7 to 4.7-inches w.c. (7 to 12 mbar)).
2. Do not use uorocarbon (FKM) with these springs at diaphragm temperatures lower than 40°F (4°C).
