What water pressure is required for the automatic ice maker to work correctly?

The automatic ice maker requires a water pressure of 0.146 to 0.834 MPa (21.3 to 121 PSI), which means a 207ml glass fills in 3 seconds. If the water pressure is below 0.146 MPa (21.3 PSI), you must purchase a pressure pump for the ice and cold water supply. The maximum length of the water supply tube should not exceed 12 meters.
