Ice Machine Operation 8
Operational Checks
CUBE WEIGHT
Cube weight increases or decreases depending on the
amount of dimple in the cube. Refer to the illustration
below. The cube weight can be increased from the factory
setting by adjusting the finish time.
Check cube finishing time. Press and hold the POWER
key pad for five seconds. Count the flashes on the ICE
light. The light will flash once for each additional minute of
freeze cycle time.
Adjust cube finishing time. Adjust in one minute incre-
ments and allow the ice machine to run several freeze and
harvest cycles, then inspect the ice cubes. If a heavier
cube weight is desired add another minute of freeze time
and repeat the process.
1) Press and hold the POWER key pad.
2) Press and release the CLEAN key pad once for each
additional minute of freeze cycle time desired. Five
minutes is the maximum additional freeze time that can
be added.
3) Press the CLEAN key pad six times to reset the
finishing time to the original factory setting.

Cleaning
Proper cleaning and maintenance of your ice machine will
increase its reliability and performance and help minimize
water and power consumption.
IMPORTANT NOTE: Poor water quality may require more
frequent cleaning, sanitizing and water filter replacement.
Clean the entire unit including the cabinet exterior periodi-
cally. Also check the ice quality. To ensure reliable,
trouble-free operation and maximum ice production, the
following cleaning and maintenance should be performed
every six months or after a prolonged shutdown.
• Sanitize ice storage bin (also before initial start-up).
• Clean condenser.
• Replace water filter.
To ensure efficient operation, an annual cleaning
performed by Sub-Zero factory certified service is recom-
mended. The ice machine will require disassembly,
cleaning and sanitizing. For the name and number of
Sub-Zero factory certified service, check the contact &
support section of our website, subzero.com or call
800-222-7820.
