cut-in setting of 6 C.
4. Allow the refrigerator to operate and stabilize at least 30 minutes, verifying the cut-out temperature is being
reached.
5. Connect refrigerant hoses to access fittings and measure air temperature at condenser intake grille.
6. Verify correct pressures with the temperature chart below.
