Operation
PRIOR TO USE
Clean the ice machine thoroughly with warm water and mild
detergent. Rinse and dry with a soft cloth to remove any
residual oil and grease left from the manufacturing process.
Refer to care recommendations on page 6.
All surfaces that come in contact with the water system
should be cleaned and sanitized prior to use. Refer to the
cleaning and sanitizing procedure on page 7. Use only the
cleaner and sanitizer made for the Sub-Zero ice machine.
Ice machine cleaner and sanitizer can be ordered online at
subzerowolfstore.com. For questions, contact Sub-Zero
customer care at 800-222-7820.
OPERATION
ICE PRODUCTION CYCLE
Depending on ambient conditions and water temperature,
one ice production cycle takes approximately 30 minutes.
1 Water ll cycle. The water inlet valve purges old water
from the system.
2 Refrigeration system start-up. The compressor starts
after the water ll cycle and remains on throughout the
freeze and harvest cycles. The condenser fan motor
starts and runs throughout the freeze cycle.
3 Freeze cycle. Water is sprayed into the inverted cups.
The water freezes layer by layer until an ice cube forms
in each cup. The control system adjusts the length of the
freeze cycle to conditions.
4 Harvest cycle. The evaporator warms, allowing the
cubes to be released and drop into the storage bin. The
control system adjusts the length of the harvest cycle
to conditions. At the end of the harvest cycle, another
freeze cycle begins.
5 Automatic shut-off. The level of ice in the storage bin
controls the automatic shut-off. When the bin is full, ice
will contact the bin thermostat, which cools, signaling ice
production to stop. When the ice level drops and ice no
longer contacts the bin thermostat, it will warm, signaling
ice production to resume.
