What should the high and low pressures be for 404a on an ice maker?

For an ice maker using R-404A refrigerant, the typical low pressure should be around 20-30 psi, while the high pressure can range from 150-200 psi, depending on the specific design and operating conditions of the unit. It's important to consult the manufacturer's specifications for precise values, as these can vary based on ambient temperature and other factors. Proper refrigerant levels and system maintenance are crucial for optimal performance.
