Siphon System
To reduce mineral build-up and cleaning frequency,
the water in the sump trough must be purged during
each harvest cycle.
When the water pump de-energizes the level in the
water trough rises above the standpipe starting a
siphon action. The siphon action stops when the water
level in the sump trough drops. When the siphon
action stops, the float valve refills the water trough to
the correct level.
Follow steps 1 through 6 under water level check to
verify the siphon system functions correctly
Water Level
Check the water level while the ice machine is in the
ice mode and the water pump is running. The correct
water level is 1/4" (6.3 mm) to 3/8" (9.5 mm) below the
top of the standpipe, a line in the water trough
indicates the correct level.
