Ice Machine Operation 6
Ice Making Operation
Depending on ambient conditions and cold water supply temperature, the ice making process will take approxi­mately 30 minutes.
1) Water fill cycle. (Initial start-up or start-up after automatic shut-off.) Before the compressor starts, the water inlet valve will purge old water from the system for about three minutes.
2) Refrigeration system start-up. The compressor starts after the water fill cycle and remains on throughout the freeze and harvest cycles. The condenser fan motor starts and runs throughout the freeze cycle.
3) Freeze cycle. The water pump sprays water into the inverted cups. The water freezes layer by layer, until an ice cube forms in each cup. The control system will adjust the length of the freeze cycle to conditions.
4) Harvest cycle. The water pump shuts off and the water inlet valve starts up to assist harvest and refill the water sump. The evaporator is warmed, allowing the cubes to release from the evaporator and drop into the storage bin. The control system will adjust the length of the harvest cycle to conditions and regulate whether the condenser fan will run. At the end of the harvest cycle, the ice machine will start another freeze cycle.
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 clip. The bin thermostat clip cools, signaling the ice machine to stop ice production. When the ice level drops and ice no longer contacts the bin thermostat clip, it will warm. The increase in temperature will restart ice production.

Operational Checks
The ice machine is factory tested and adjusted before shipping. Normally, new installations do not require any adjustment. Routine adjustments and maintenance proce­dures are not covered by the warranty.
To ensure proper operation, follow the operational checks when starting the ice machine for the first time, after a prolonged out of service period and after cleaning and sanitizing.
WATER LEVEL
The ice machine maintains the correct water level. The water level is not adjustable.
BIN THERMOSTAT
The bin thermostat signals the ice machine to stop ice production when the bin is full. It is preset for normal ambient temperatures and adjustments are usually not necessary.
To check operation of the bin thermostat, place three ice cubes on the thermostat clip for about five minutes, ice production should stop. The ice machine should restart five minutes after the cubes are removed. Refer to the illustration below.
If ice production stops before the bin is full or continues after the bin is full, ambient temperatures are probably too high or too low. The level of ice can be adjusted by follow­ing the steps below. The bin thermostat control is located behind the kickplate. Refer to the illustration below.
1) To access the bin thermostat, remove the four screws attaching the kickplate and tilt forward to remove.
2) Turn the bin thermostat control to the left to decrease the level of ice or to the right to increase the level of ice in the bin before automatic shut-off.
3) Reinstall the kickplate.
Power is supplied to ice machine during this procedure. Avoid contact with the fan blade and the electrical connections.

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 incre­ments 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.
Due to regulatory restrictions, cleaner and sanitizer do not ship with the ice machine. Cleaner and sanitizer can be ordered online at subzerowolfstore.com. For questions, contact Sub-Zero customer care at 800-222-7820.
IMPORTANT NOTE: Poor water quality may require more
frequent cleaning, sanitizing and water filter replacement.
Clean the entire unit including the cabinet exterior periodi­cally. 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 recom­mended. 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.

CLEANING AND SANITIZING
Cleaning and sanitizing of all surfaces that come in contact with the water system should be performed every six months. The following steps outline the cleaning and sanitizing procedure with the ice machine in place.
Use only the cleaner and sanitizer made for your Sub-Zero ice machine. The cleaner removes lime scale or other mineral deposits and the sanitizer disinfects and removes algae and slime.
If the ice machine requires more frequent cleaning and sanitizing, consult a qualified professional to test the water quality and recommend appropriate water treatment. An abnormally dirty ice machine must be disassembled for proper cleaning and sanitizing by Sub-Zero factory certified service.
Use only the Sub-Zero approved ice machine cleaner and sanitizer and follow all label directions and warnings. Damage to the ice machine evaporator caused by incorrect chemical usage is not covered by the warranty.
1) Add 4 ounces (115 ml) of undiluted ice machine cleaner
to a container that will fit under the lifted water shutters. Refer to the illustration below.
2) Press the CLEAN key pad. The ice machine will initiate a two minute harvest to remove any remaining ice from the evaporator.
3) Remove all ice from the bin.
4) Wait three minutes until the CLEAN light flashes, then
add the prepared cleaner by lifting the water shutters and pouring directly into the spray area.
5) The ice machine will automatically time out a ten minute cleaning cycle, followed by eight rinse cycles, and stop. The CLEAN light will turn off to indicate the cleaning cycle is complete. This entire cycle lasts approximately 30 minutes.
6) Add 1 tablespoon
(15 ml) of undiluted ice machine sani-
tizer to a container that will fit under the lifted water shutters.
7) Press the CLEAN key pad. Wait three minutes until the CLEAN light flashes, then add the prepared sanitizer by lifting the water shutters and pouring directly into the spray area. The ice machine will automatically time out a ten minute sanitizing cycle, followed by eight rinse cycles, and stop. The CLEAN light will turn off to indicate the sanitizing cycle is complete. This entire cycle lasts approximately 30 minutes.

Cleaning
STAINLESS STEEL
To clean stainless steel surfaces of the ice machine, use a soft, nonabrasive stainless steel cleaner like Signature polish and apply with a soft lint-free cloth.
Signature polish is available from Signature Limited Laboratory, P. O. Box 13436, Dayton, Ohio 45413, or call 877-376-5474.
To bring out the natural luster of the stainless steel, lightly wipe the surface with a water-dampened microfiber cloth followed by a dry polishing chamois. All work should follow the grain direction of the finish. Better results are obtained by keeping the cloth in continuous contact with the stainless steel.
Do not use a metallic or highly abrasive cleaner or cloth, as this will scratch the stainless steel finish.
CONDENSER CLEANING
A dirty condenser restricts airflow, resulting in excessively high operating temperatures. This reduces ice production and shortens component life. The condenser should be cleaned every three to six months or after a prolonged shutdown.
The condenser of the ice machine is located at the bottom of the unit, behind the kickplate. Refer to the illustration below. To clean, follow these steps:
1) Remove the four screws attaching the kickplate and tilt forward. Clean kickplate openings before replacing.
2) Clean the outside of the condenser with a soft brush or a vacuum with a brush attachment. Clean from top to bottom, not side to side. Be careful not to bend the condenser fins.
3) Using a flashlight, check for dirt between the fins. If dirt remains between the fins or if the condenser fins are bent or flattened, contact Sub-Zero factory certified service.
Before cleaning the condenser, shut off power to the unit at the control panel. Wear gloves to avoid injury from sharp condenser fins.
