making operation.

DELAY Touch once to initiate a 2-hour delay in ice produc-

tion, touch a second time for a 4-hour delay and a

third time for an 8-hour delay. The corresponding

number will illuminate indicating the delay period.

Touch a fourth time to cancel.

CLEAN Touch to initiate the cleaning cycle. ‘CLEAN’ will

CUBE WEIGHT

Cube weight increases or decreases depending on the

amount of dimple, or depression in the octagonal-shaped

ice cube. Cube weight can be adjusted by increasing the

freeze time.

To adjust cube weight:

1 Touch and hold ‘POWER’.

2 Touch and release ‘CLEAN’ once to add one minute of

freeze time. Inspect the cubes after several production

cycles and repeat if a heavier cube is desired. Up to ve

minutes of additional freeze time can be added.

3 Touch ‘CLEAN’ six times to reset freeze time to the

factory setting.

ICE LEVEL

A thermostat in the ice storage bin signals ice production to

stop when the bin is full. If ice production stops before the

bin is full or continues after the bin is full, the ice level can

be adjusted. The thermostat control is located behind the

kickplate. Refer to the illustration below.

To adjust ice level:

1 Remove the kickplate to access the thermostat control.

2 Turn the control to the left to decrease the level of ice or

to the right to increase the level.

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.

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.

surface with a water-dampened microber cloth followed by

a dry polishing chamois. Always follow the grain of stainless

steel.

lift the water shutters and pour 4 ounces

(115 ml) of undi-

luted ice machine cleaner directly into the spray area.

Refer to the illustration below.

4 A 10-minute cleaning cycle begins, followed by eight

rinse cycles. When the process is complete, the CLEAN

light will no longer be illuminated. The entire cleaning

cycle takes approximately 30 minutes.

5 Touch ‘CLEAN’. Wait three minutes until the CLEAN light

ashes, then lift the water shutters and pour 1 table-

spoon

(15 ml) of undiluted ice machine sanitizer directly

into the spray area.

Maintenance

WATER FILTER REPLACEMENT

The water lter should be replaced every six months, after

a prolonged shutdown or after 8000 ice making cycles.

‘REPLACE FILTER’ will illuminate on the control panel

indicating the water lter needs to be replaced. The ice

machine bypasses the lter when it is removed, so the water

supply does not need to be turned off.

Replacement Sub-Zero water lters 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 water lter replacement.

To replace water lter:

1 To remove the water lter, rotate one-quarter turn

counterclockwise and the lter will pop out. Refer to the

illustration below.

2 Reverse the process to install the new lter.

3 Touch and hold ‘CLEAN’ for 6 seconds to reset the

indicator.

CONDENSER CLEANING

CAUTION

Before cleaning the condenser, turn power off at the

control panel. Wear gloves to avoid injury from sharp

condenser ns.

The condenser is located behind the kickplate. To access,

remove the kickplate. Use a soft bristle brush and vacuum

to remove dust and lint from the condenser. Clean the con-

denser every six months. Refer to the illustration below.

IMPORTANT NOTE: To avoid damaging condenser ns,

vacuum in the direction of the ns.

CAUTION

Failure to clean the condenser could result in tempera-

ture loss, mechanical failure or damage.

CARE RECOMMENDATIONS

Maintenance

PROLONGED SHUTDOWN

If the ice machine is to be removed from service for an

extended period or exposed to temperatures of 32°F

(0°C)

or below, follow the procedure for prolonged shutdown and

winterization.

Prolonged shutdown and winterization procedure:

1 Perform the cleaning and sanitizing procedure on page 7

to prevent mildew growth.

2 Disconnect electrical power at the circuit breaker or

service panel.

3 Turn off the water supply.

4 Remove water from the water reservoir.

5 Disconnect the incoming water supply line at the rear of

the unit and allow it to drain.

6 Disconnect the vinyl hose from the water pump and

allow it to drain.

7 Verify water is not trapped in any of the water supply or

drain lines. Compressed air can be used to blow out the

lines.

8 Use a spray bottle with a solution of 1 tablespoon (15 ml)

sanitizer to 1 gallon

(3.8 L) water and spray all interior

surfaces. Do not rinse, allow it to air dry.

9 Block the door partially open to provide air exchange

and prevent mildew growth.
