Collins Cube - Tray & Inserts

The Collins cube tray works similar to the 2" cube tray. First, fill the tray with water to the fill line. The inserts can be installed before or after water is added. Make sure inserts are flush with the bottom of the tray and no air bubbles are underneath. Start the cycle then return in 8-12 hours for ice harvesting.

When harvesting, allow for the ice to thaw for 1-2 minutes before removing from the tray. Peel the inserts from the cubes and store in a safe place before next use.

The flat plastic pieces at the bottom of the tray are called inserts. They are critical to the formation of clear ice. Not using these during the process will lead to cloudy ice on the bottom.

Please be careful with these inserts and store them in a safe place when not in use. Replacement trays and inserts can always be repurchased. If damage occurs within the 3 month warranty period, please reach out to customer service for more information.

To achieve a 1" x 2" x 4" shape, run the ice machine for the entire 8-12 hour cycle. The machine will automatically sense the ice and go into "Ice Ready" mode. 

You may desire a 1" x 1" x 4" for more symmetry in your Collins cube. To achieve, we recommend retrieving the ice around the 4-6 hour mark. This may take some testing to optimize for your particular machine and environment.

To do so, cancel the cycle at the desired time. Note that you will need to allow 5+ minutes for the tray to thaw from the cold plate before removing and an additional 5+ minutes to thaw the cubes from the tray.

Do not restart the ice maker with ice in the tray.

Growing the Collins cube to the full ice height (2") will take the typical freeze time of 8-12 hours. If a partial cube (1" height) is desired, the cycle can be stopped around the 4-6 hour mark.

To do so, cancel the cycle at the desired time. Note that you will need to allow 5+ minutes for the tray to thaw from the cold plate before removing and an additional 5+ minutes to thaw the cubes from the tray.

Do not restart the ice maker with ice in the tray.

Whisps or small inclusions around the edges, faces or corners can occur from run to run appearing on a couple of cubes. Consistently seeing issues on all 3 cubes?

• Dirty Tray/Insert. Clean with warm water and dish soap before first use and every 5-10 runs after.
• Water not up to "Fill Line" of tray.
• Inserts not installed or pushed down all the way. See How It Works video for more info. 
• Poor water quality (high mineral content) makes it difficult to start the ice growing process. Try different water sources (tap, filtered & bottled, aerated & still). Read more about water quality and clear ice making here. 
• Mixer not mixing. If the mixer is not heard ramping up at the start of a run it may be the issue. 
• Bad tray/insert combination/orientation. Please try changing the orientation between the inserts and tray. 

If all other avenues have been explored and issues persist, please reach out for additional support.
