3B. WATER DRAIN

To allow water to drain from the evaporator, the dump valve energizes for 90 seconds, then de-energizes.

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 lockout” has expired.
