Use and Operation
Once started, the ice machine will automatically
make ice until the bin is full of ice. When ice level
drops, the ice machine will resume making ice.
There are four indicator lights at the front of the
control box that provide information on the
condition of the machine.

If the Water light is on, the machine has sensed a
lack of water. Check the water supply to the
machine. The water could have been shut off or the
water filter cartridges might need to be changed.
If the De-Scale light is on, the machine has
determined that it needs to be cleaned. Contact an
authorized Scotsman service agent and have the
machine cleaned, de-scaled and sanitized.
