To change the size of your gems:
1. Press and hold “Ice Making On/Off” and “Activate Cleaning Cycle” buttons at the same time. The display screen will then display a scale of 1-7, with 1 being the smallest and 7 being the largest gem size. (The default ice gem is a size 4.)
2. Cycle through the size scale by selecting the “Activate Clean Cycle” button.
3. Once your desired gem size is determined, press and hold both buttons to select and exit. Note that increasing the size of the ice gems will also increase the time it takes Forge to make ice.
Changing the size of your ice gems is only possible when Forge is not in ice making mode.
