Thank You

Thank you for purchasing your new Sub-Zero PRO 48 unit.

With Sub-Zero, you can rely on a 60-year tradition of

quality and reliability.

Built in to cabinetry or freestanding, the PRO 48 is just

the latest example of Sub-Zero pushing food preservation

to new heights. And of course, the PRO 48 meets rigorous

Department of nergy standards for residential use.

Featuring a glass door on model 648PROG or top-to-

bottom stainless steel on model 648PRO. The PRO 48

brings together the latest technology and finest features in

home refrigeration to give you the freshest food possible.

Your Sub-Zero is protected by a warranty that is one of

the finest in the industry. Take a moment to read the

warranty statement at the end of this guide and refer to it

should service become necessary.

This use & care guide will answer most of your questions

about the features, operation and maintenance of your

PRO 48 unit. If you have questions that are not addressed

here, call Sub-Zero customer care at 800-222-7820 or visit

our website, subzero.com.

Dual Refrigeration

The PRO 48 continues the Sub-Zero tradition of superior

quality and reliability. Sub-Zero pioneered the develop-

ment of our dual refrigeration system, giving you optimum

fresh and freezer food storage in ideal self-contained

sections. Both refrigerator and freezer maintain accurate,

consistent temperatures. Dual refrigeration keeps your

food fresh longer than any other system available.

With dual refrigeration, the freezer maintains a constant

temperature within one degree of the temperature you set

within our range of -5°F (-21°C) to +5°F (-15°C), without

unwanted moisture and odor from the refrigerator. Simi-

larly, you can adjust the refrigerator temperature within a

range of 34°F (1°C) to 45°F (7°C), for proper humidity levels

tailored for longer food life expectancy.

The dual refrigeration system also means there is no

transfer of fresh food odors to frozen food or ice. The

Sub-Zero system does not freeze the moisture out of the

air in the fresh food section.

Sub-Zero dual refrigeration is also more energy efficient

than old-fashioned single refrigeration systems. When the

refrigerator is used frequently during the day it does not

require the freezer to circulate its very cold, dry air to the

refrigerator. Instead, the refrigerator uses moist air to keep

fresh foods fresh and energy use minimal.

lectronic Control System

The electronic control system of the PRO 48 monitors and

accurately displays compartment temperatures within one

degree of your pre-set temperatures. It also monitors the

operation of the unit and lets you know if there is a

problem. The interior control panel located at the top of

the refrigerator door compartment has key pads to set

temperatures and control functions of the electronic

control system. Refer to the illustration below.

TEMPERATURE CONTROL

Your new PRO 48 was thoroughly inspected and tested

before it was shipped from the Sub-Zero factory. Tempera-

tures are preset at 38°F (3°C) in refrigerator compartments

and 0°F (-18°C) in the freezer compartments.

There are three sets of WARM R and COLD R key pads

on the interior control panel, two for the refrigerator

compartments (upper door and lower drawers) and one for

the freezer compartments. To adjust the temperature in

any of the three compartments, press the WARM R or

COLD R key pad for that compartment. Digital tempera-

tures for each of the three compartments are displayed in

the exterior temperature display.

Temperature ranges are -5°F (-20°C) to +5°F° (-15°C°) in the

freezer sections and 34°F (1°C) to 45°F (7°C) in the refriger-

ator sections. It is normal for temperatures to fluctuate

slightly, depending on external influences such as an open

door, the degree of humidity and room temperature.

IMPORTANT NOTE: Always allow 24 hours for compart-

ments to reach the temperature you set.

PRO 48 Use & Care 6

EXTERIOR TEMPERATURE DISPLAYS

lectronic control system functions, such as digital

temperatures and service indicators, are displayed in two

exterior temperature displays located on the grille. The

display in the lower left area of the grille shows the

temperature and indicators for freezer compartments, and

the display in the lower right gives readouts for refrigerator

compartments. Refer to the illustrations below.

TEMPERATURE DISPLAY

The electronic control system can display temperatures in

Fahrenheit (°F) or Celsius (°C).

To convert Fahrenheit to Celsius, turn the unit off then

back on. Within the first minute after turning the unit on,

press and hold the ALARM key pad and the POW R key

pad simultaneously for five seconds, then release. A ‘C’

will appear in each of the exterior temperature displays.

Follow the same procedure to convert from Celsius to

Fahrenheit.

lectronic Control System

POWER

The POW R key pad on the control panel will shut off all

electrical power to the unit. When the power is off, the

OFF indicator light will be visible in the exterior tempera-

ture display. Using the POW R key pad means you do not

have to shut off power at the circuit breaker or unplug the

unit. The POW R key pad can be used for extended

vacations.

It is possible to shut off power to one compartment of the

PRO 48 for an extended period without affecting operation

of the other compartments.

First, turn the unit off by pressing the POW R key pad.

Then push and hold the WARM R key pad of the

compartment you wish to shut down. Press the POW R

key pad to turn the unit back on. The disabled zone will be

indicated with ‘--’ in the exterior temperature display.

Repeat the process to resume power to the compartment.

ALARM FEATURE

The PRO 48 has an alarm feature that lets you know with

an audible chime if a door or drawer is left ajar. The alarm

will sound after 30 seconds if a door or drawer is left open

and will stop once the door or drawer is closed. This alarm

can be disabled for cleaning or restocking by pressing the

ALARM key pad on the control panel.

ICE MAKER CONTROL

The IC MAK R key pad on the control panel switches

power to the ice maker system on or off. Use the IC

MAK R key pad to shut down ice maker operation during

extended vacations. The ice bucket icon will be visible in

the exterior temperature display if the ice maker system

is on.

VISUAL SERVICE DISPLAY

The electronic control system monitors compartment and

component temperatures as well as the ice maker system.

If there is a temperature or ice maker problem, you will be

alerted by a flashing S RVIC indicator light in the exterior

temperature display. This same S RVIC light will also

flash if the condenser needs cleaning.

SABBATH MODE (STAR-K)

Sabbath mode is available for the observance of certain

religious holidays. This mode turns off the lights, ice maker

system and door alarm and prevents them from turning on

again. Normal cooling operations will still take place.

To initiate Sabbath mode while the unit is on, press the

POW R key pad on the control panel so that ‘OFF’ is

visible in the exterior temperature display. Then press and

hold the POW R key pad for 10 seconds. This will turn the

unit back on with lights and ice maker disabled. There will

be four short chimes, indicating that the Sabbath mode

has been set. To return the unit to normal operation, press

and release the POW R key pad.

PRO 48 Use & Care 10

Water Filtration System

The PRO 48 features a water filtration system that

supplies filtered water to the ice maker to produce great-

tasting ice. The water filter has been factory installed

behind the grille assembly.

It is important that the operation, maintenance and filter

replacement requirements be carried out as scheduled.

Refer to the following information on the water filter

cartridge monitor.

IMPORTANT NOTE: If the unit has been turned off or the

ice maker disabled for one month or longer, the water filter

cartridge should be replaced once the unit and ice maker

are back in operation.

IMPORTANT NOTE: Do not use with water that is microbi-

ologically unsafe or of unknown water quality without

adequate disinfection before or after the system. Systems

certified for cyst reduction may be used on disinfected

waters that may contain filterable cysts.

Refer to the performance data on page 25 for additional

information regarding the water filtration system.

WATER FILTER CARTRIDGE MONITOR

The water filter cartridge is designed to last for up to one

year of continuous use of the ice maker. The electronic

control system monitors the life of the water filter cartridge

and indicates when it needs to be replaced. An indicator

that reads ‘R PLAC FILT R’ will be visible in the left

side exterior temperature display. Follow steps to replace

the water filter cartridge on the following page.

Once the filter cartridge has been replaced, the control

automatically resets the water filter life monitor and the

‘R PLAC FILT R’ indicator will no longer be displayed.

Although it is designed to last for up to one year of use,

the actual life of the filter cartridge may vary with water

supply conditions. Therefore, it is recommended that the

filter cartridge be replaced when the ‘R PLAC FILT R’

indicator is displayed or if the ice cubes become hollow or

smaller.

IMPORTANT NOTE: The warranty for the water filter

cartridge supplied with the unit only covers defects in

materials or workmanship and not replacement due to

normal use.

REPLACEMENT CARTRIDGES

Replacement Sub-Zero water filter cartridges can be

ordered online at subzerowolfstore.com. For questions,

contact Sub-Zero customer care at 800-222-7820.
