Do I need to take the ice out of the machine when the ice is full?
I mean, does the machine has a freeze already for storage ice and how long does the ice can be stored inside the machine?
You don't need to take it out of the machine. When ambient temperature is 20-25 ℃, it can be stored for 8-12 hours. It will automatically start to make ice when it melts a little and stop when the ice is full.
Can you please provide the specs for the feed and drain tubing? We are having a unit professionally installed and the plumber needs to know what the connections will be.
