Appendix M: Pressure switch settings

This chart shows the operating temperatures of different pressure switch settings at sea level.

• At temperatures of 88°Celsius(C) (191°Fahrenheit (F)) to 99°C (210°F) the pressure switch setting is 10 pounds per square inch gauge (PSIG) at sea level.
• At 104°C (220°F) the pressure switch setting is 13 PSIG at sea level
• At 110°C (230°F) the pressure switch setting is 16 PSIG at sea level
• At 116°C (240°F) the pressure switch setting is 20 PSIG at sea level
• At 121°C (250°F) the pressure switch setting is 25 PSIG at sea level
• At 127°C (260°F) the pressure switch setting is 31 PSIG at sea level
• At 132°C (270°F) the pressure switch setting is 37 PSIG at sea level
• At 138°C (280°F) the pressure switch setting is 45 PSIG at sea level
• At 143°C (290°F) the pressure switch setting is 53 PSIG at sea level
• At 149°C (300°F) the pressure switch setting is 62 PSIG at sea level
