Partial/Full Drain Selection
Controls timing for inlet water valve and pump motor
in the freeze cycle.
Partial Drain: Pump motor energizes after freeze
cycle water supply time 1 (CB Setting 12) timer
terminates. During the rst freeze cycle after startup
or following a bin control initiated shutdown and
restart, freeze cycle water supply times 1 and 2 (CB
Settings 12 and 15) are doubled.
Full Drain: Pump motor energizes after freeze cycle
water supply time 1 (CB Setting 12) timer terminates.
If full drain is selected, change freeze cycle making
water supply times 1 and 2 (CB Settings 12 and 15)
to the full drain times listed in this table and move
the water tank drain pipe to the drain position. For
details, see "III.H.2. Ice Clarity."

Harvest Cycle High Temperature Control
Active if type setting (CB Setting 30) is set to 1, 2,
or 3. If control board thermistor temperature at the
beginning of harvest cycle is equal to or greater than
the harvest cycle high temperature control setting,
fan motor operates continuously in harvest cycle.
