364. The low-pressure cut-out switch settings vary with the refrigerant used and the temperature application. If the low-pressure cut-out switch for a particular application is set with a cut-in pressure of 5 psig, what would be the cut-out pressure if the differential is 7.5 psig?
The cut-out pressure is calculated by subtracting the differential from the cut-in pressure: 5 psig — 7.5 psig = -2.5 psig. This negative value indicates a vacuum of 2.5 psi, which is approximately 5 inches of mercury vacuum.
