User Manual

Reasons the machine might shut itself off:

•Lack of water.

•Freeze cycle takes too long.

•Harvest cycle takes too long.

To Manually Reset the machine.

•Push and release the Off button.

•Push and release the On button.

•High discharge temperature.

•Controller self test failure.

Check the following:

1.Has the water supply to the ice machine or building been shut off? If yes, the ice machine will automatically restart within 25 minutes after water begins to flow to it.

2.Has power been shut off to the ice machine? If yes, the ice machine will automatically restart when power is restored.

3.Has someone shut the water off to a water cooled unit? If yes, after the water supply has been restored the ice machine may need to be manually reset.

4.Is the curtain open because some ice is stuck under it? If so, remove the ice and the machine should start in a few minutes.

Note: Curtain can be removed & replaced anytime the machine is in a standby mode or when it is in a freeze cycle. However, removal of the curtain during freeze will result in water flowing into the bin. Removal of the curtain during harvest terminates harvest at that point and, if left off, will result in the machine shutting off.

To Shut the Machine Off:

Move the On Off switch to the Off position.

or, at the controller

Push and hold the Off button for 3 seconds or until the machine stops.
