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.
