Section 6 Electrical System

Automatic Shut-Off

An 8 minute lockout starts when the compressor de-energizes. When the ice drops away from the bin level probe the ice machine will begin an initial start-up cycle, provided the “8 minute lock-out” has expired.

8 Minute Lock-out

The bin level light will flash until the 8 minute lock-out expires.

After the 8 minute lock-out expires the bin level light will de-energize.

The 8 minute lock-out time can be overridden by moving the ON/OFF/ ICE toggle switch from ICE to OFF then back to ICE.
