Performance of the Whynter UIM-502SS

The Whynter UIM–502SS relies on a two-stage process to make high-quality ice cubes. The two stages are the freezing cycle and the harvest cycle.

The freezing cycle starts when the compressor pumps the powerful refrigerant. A small internal motor and water pump blow the air and circulate the water in the appliance. When a sheet of ice has been formed, the ice maker will stop the freezing cycle and begins the harvest cycle. 

In the harvest cycle, the compressor will continue to operate but the water pump will stop. The valve of the gas opens and warms up the evaporator, which will eventually help the ice cubes to fall into the ice basket. After harvesting all the ice cubes, the freezing cycle will start all over again

The Whynter is a drop cut ice maker that produces a sheet of ice, which will later drop on the heated cutter. The appliance forms sheets of ice cubes at a relatively very low noise level. We only have to turn on the water tap and switch on the ice cycle, from the control panel at the front of the appliance. The ice maker starts working automatically and the ice cubes will get harvested in the bin.
