    Yes this is in florida with us gauges

    I have the shop manual and it states:

    The refrigeration system functions normally Gauge reading:
    Low-pressure side: 0.15 to 0.25 MPa (1.5 to 2.5 kgf/cm2)
    High-pressure side: 1.37 to 1.57 MPa (14 to 16 kgf/cm2)
    ​
    I tried using an online converter to psi but it didn't make sense.
    I can't find anywhere what the readings should be in psi.

    Conversion is pretty straight forward.

    Low-pressure side: 0.15 to 0.25 MPa (22 PSI to 36 PSI)
    High-pressure side: 1.37 to 1.57 MPa (199 PSI to 228 PSI)
