And of course, the PRO 48 still meets rigorous Department of Energy 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 on page 31 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 Service at 800-222-7820 or visit our website, subzero.com.

Dual Refrigeration

he PRO 48 continues the Sub-Zero tradition of superior

T quality and reliability. Sub-Zero pioneered the development 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. Similarly, 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.

PRO 48 Use & Care 10

Water Filtration System

he PRO 48 features a water filtration system that

T supplies filtered water to the ice maker to produce greattasting 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.

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 “REPLACE FILTER” will be visible in the left side exterior temperature display. Follow steps to replace the water filter cartridge on the following page.

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.

Once the filter cartridge has been replaced, the control automatically resets the water filter life monitor and the “REPLACE FILTER” 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 “REPLACE FILTER” 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 Sub-Zero water filter cartridges (4204490) can be ordered by calling 800-222-7820 or online at subzerowolfstore.com.

FILTER CARTRIDGE REPLACEMENT

1) Lift the grille assembly to access the water filter. To lift the grille, pull out on the bottom edge of the grille and tilt the grille frame forward. Refer to the grille access illustration below.

2) Slowly rotate the old filter cartridge one-quarter turn counterclockwise to disengage. Gently twist until the cartridge is free from the base. DO NOT pull. There will be water in the filter cartridge, so it is normal for a small amount of water to spill out. Refer to the water filter illustration below.

3) Remove the new filter cartridge from its packaging and carefully remove the cap.

4) Line up the cartridge so that the locking tabs can be inserted into the filter head.

5) Rotate the filter cartridge into the base about one-quarter turn clockwise until it stops. DO NOT overtighten.

6) After the new filter cartridge is installed, the first full bucket of ice produced should be discarded. This will help clean the water system and clear air from the line. Allow 24 hours before discarding the first bucket of ice.

WATER FILTER BYPASS MODE

If you choose not to use the water filtration system, the system can be placed in water filter bypass mode. In this mode, the water supplied to the ice maker will not be filtered and the electronically controlled water filter monitor will be deactivated.

The water filtration system automatically goes into bypass mode when the filter cartridge is removed. Once a filter cartridge is reinstalled, the water filtration system will be activated and the water filter monitor function will resume.

IMPORTANT NOTE: If you are using a reverse osmosis

system, the water filter cartridge must be removed to put the water filtration system into bypass mode.

he ice maker in the PRO 48 is fully automatic and has

T been tested at the Sub-Zero factory. To turn the ice maker on or off, depress the ICE MAKER key pad on the control panel. When the ice maker is on, it will be operating any time the drawer is closed.

IMPORTANT NOTE: A reverse osmosis system can be

used with the PRO 48, provided there is constant water pressure of 20 psi (1.4 bar) to 120 psi (8.3 bar) supplied to the unit at all times. In this application, the integrated water filtration system must be set to bypass mode. This is achieved by removing the water filter cartridge. Refer to page 11 for detailed instructions.

Ice Production

The ice maker is designed to produce enough ice for normal family use. The timing of ice making cycles will vary depending on load conditions, door and drawer openings and room temperature. On average, you can expect a cycle of ice (eight cubes per cycle) every two hours.

Door and Drawer Operation

he PRO 48 refrigerator and freezer door hinges have an

T auto-close system that allows doors to finish closing automatically. As you close the door, the built-in cam takes over to close the door the final 15°. A built-in door stop allows both doors to stay open at approximately 120°.

For corner applications, an optional door stop kit is available that limits the door opening to 90° (4152280). Optional accessories are available through your Sub-Zero dealer. To obtain local dealer information, visit the Showroom Locator section of our website, subzero.com.

The PRO 48 refrigerator and freezer drawers have an auto-close system that allows drawers to finish closing automatically. The drawers have an automatic stop built in at full extension.

For extra ice capacity, remove the ice bucket with the ice maker system on and allow the drawer to fill with ice.

IMPORTANT NOTE: Removing the ice bucket will not

increase the rate of ice production.

If ice is not used on a regular basis it tends to fuse together. To avoid this, empty the ice bucket periodically allowing it to replenish with a fresh supply.

Keeping Food At Its Best 15

subzero.com

Keeping Food Fresh

our Sub-Zero unit features our unique dual compressor

Y refrigeration system to keep food fresher longer. However, the quality and safety of your food also depends on how you handle it.

The information in this section gives you the most up-todate handling and storage recommendations to help you keep food at its best. If you have specific questions that are not addressed here, contact a University or County Extension Service or your local utility company.

Most food inevitably deteriorates over time. From the very beginning until it is consumed, food undergoes changes. Microorganisms get into food, multiply and cause spoiling.

Enzymes that occur naturally in food continue the ripening process even after the food is harvested. Improper temperatures cause food to deteriorate faster. Changes in humidity cause wilting and shriveling that can lead to spoiling.

HANDLING RECOMMENDATIONS

• Follow the recommended storage times and tempera-

tures in this guide. Your Sub-Zero unit helps to slow the ripening process by tailoring temperatures to each section as needed.

• Use specially designed compartments for dairy foods,

deli foods and fresh produce. These compartments maintain temperature and humidity levels that keep specific food groups fresh.

• Rotate food in refrigeration units, using a first-in,

first-out system.

• When food does spoil, it’s usually obvious. It becomes

moldy, has an off-odor and looks rotten. But there are times when spoiling may not be so apparent. If you think a food has been stored too long, discard it. Don’t taste it to check if it’s okay.

Sub-Zero’s dual refrigeration system is specifically designed to combat these changes and keep your food fresh longer. The individual refrigerator and freezer systems have been designed to maintain accurate, consistent temperatures and proper humidity levels for longer food life expectancy. Dual refrigeration eliminates transfer of fresh food odors to frozen food or ice and does not freeze the moisture out of the air in the fresh food section.

In addition, good handling practices can minimize the rate of changes in food.

Food Storage Recommendations 16

Keeping Food Safe to Eat

ost food-borne illness is caused by bacteria such as

M Staphylococcus, Salmonella, E-coli and Clostridium Botulinum (the bacteria that causes botulism). These bacteria grow rapidly at temperatures between 40˚F (4˚C) and 140˚F (60˚C), a range that’s called the Danger Zone. Never leave food in the danger zone for more than two hours. When the bacteria have multiplied to the millions in warm temperatures, they cause illness. Some bacteria cause flu-like symptoms, while others cause serious illness or even death. Young children, the elderly and people who are already ill are more likely to become sick from food poisoning.

To reduce your risk of food-borne illness, use the following techniques to keep your food safe to eat:

WHEN YOU STORE FOOD

• Monitor temperatures of the refrigerator and freezer

sections on the electronic control panel of your Sub-Zero unit. Keep the refrigerator temperature at 40˚F (4˚C) or below and freezer temperature at 0˚F (-18˚C).

• Follow the recommended refrigerator and freezer

storage times and temperatures in this guide.

• Store raw meat, poultry and seafood separate from

other foods. Keep juices from these packages from dripping on other food.

• Never taste food that looks or smells strange to test its

freshness. Discard it.

WHEN YOU’RE SHOPPING

• Place packages of raw meat, seafood or poultry in

plastic bags to keep them from dripping on other foods.

• Shop for meat, seafood and poultry last. Don’t leave

these foods in a hot car when you’ve finished shopping. Take along a cooler in hot weather or when you have to travel long distances.

• Check ‘use by’ and ‘sell by’ dates on foods to make

sure they’re fresh. Use extra care when buying deli food. Buy only the amount you will use in 1–2 days. Discard hot or cold deli food that has been at room temperature for more than two hours.

• For refrigerator storage, leave raw meat, poultry and

seafood in its original wrapper unless it is torn. Repeated handling can introduce bacteria to these foods.

• Wrap food stored in the refrigerator in foil or plastic

wrap, or place it in plastic bags or airtight containers to keep it from drying out. Date all packages.

• For freezer storage, use freezer wrap, freezer-quality

plastic bags or aluminum foil over the commercial wrap if foods will be stored in the freezer for more than a couple of months. This minimizes dehydration and quality loss. Single layers of aluminum foil may tear and cause freezer burn.

Food Storage Recommendations 17

Keeping Food Safe to Eat

WHEN YOU PREPARE FOOD

• Clean everything that comes in contact with food.

• Wash your hands for 20 seconds before and after

handling food.

• Sanitize counters, equipment and utensils after

handling raw meat, seafood or poultry. Rinse with a diluted chlorine bleach solution of one teaspoon to one quart of water.

• Use clean kitchen towels, sponges and cloths. Replace

sponges every few weeks.

• Use disposable plastic gloves if you have an infected

cut or burn on your hands.

• Thaw food in the refrigerator or microwave oven, not

on the counter. When you thaw food in a microwave oven, cook it immediately.

• Marinate food only in the refrigerator.

• Rinse poultry and seafood in cold water before

cooking.

• Avoid cross-contamination in preparing food. Keep raw

meat, poultry and seafood and their juices away from other food. For example, don’t use the same surface and utensils for preparing raw meat, poultry and seafood that you use for preparing salad ingredients.

• Thoroughly clean your plastic and wooden cutting

boards. Wash with hot water and soap and rinse with a diluted chlorine bleach solution of one teaspoon to one quart of water.

WHEN YOU COOK FOOD

• Cook meat to an internal temperature of 165˚F (75˚C) or

above and poultry to 180˚F (80˚C) or above. For cuts more than two inches thick, use a meat thermometer to check the temperature. For thinner cuts, clear juices (not pink) are a sign of doneness.

• If you are cooking frozen meat or poultry that has not

been defrosted, increase the cooking time to 1 the time required for thawed items.

• Roast meats or poultry in oven temperatures of 325˚F

(165˚C) or above.

• Cook eggs until the yolk and white are firm, not runny.

• Don’t use recipes in which eggs remain raw or partially

cooked.

• If your microwave has a temperature probe, use it.

Check temperatures of meat and poultry in at least three spots. Rotate foods during microwaving.

• Don’t taste raw or partially cooked meat, poultry, eggs

or fish.

WHEN YOU HAVE LEFTOVERS

• Refrigerate or freeze cooked leftovers in small, covered

containers within two hours after cooking. Make sure there is adequate air space around the containers so that food can cool down quickly.

• Remove the stuffing from meat or poultry and store it

separately.

/2 times

• Date packages of leftovers and use within a safe

period of time.

• Cover and reheat leftovers thoroughly before serving.

• Bring sauces, soups and gravy to a boil. Heat other

foods to 165˚F (75˚C).

• If you think food may be spoiled, discard it. When in

doubt, throw it out.

Food Storage Recommendations 18

Fresh Food Storage

helf life of fresh foods varies depending on how fresh it is

S when you buy it. To keep your food fresher longer, follow the recommended storage tips.

Vegetables: Wash vegetables in cool water and drain. Store in airtight containers or plastic wrap. Vegetables stay fresh longer in high humidity storage.

Fruits: Wash and dry fresh fruits. Store more aromatic fruits in plastic bags. Most fruits stay fresh longer in low humidity storage.

Prepackaged meats: Store in original packaging. After opening, rewrap tightly in plastic wrap or aluminum foil.

Fresh meats, fish and poultry: Remove store wrappings, then rewrap in plastic wrap, foil or waxed paper and refrigerate immediately.

Eggs: Store eggs unwashed in their carton or a portable egg tray. Use within three weeks.

Milk, cream and cottage cheese: Keep carton closed. Store on refrigerator shelf and use within 1–2 weeks.

Cheese: Store in original packaging until ready to use. After opening, rewrap tightly in plastic wrap or aluminum foil.

Leftovers: Let cool and cover tightly with plastic wrap or foil. Airtight plastic containers work well to prevent drying out and odor transfer.

ETHYLENE

Some fruits and vegetables will produce ethylene, a gas that initiates the ripening process. Ethylene can cause premature ripening in some foods, while in others, it can actually cause damage. To reduce unnecessary spoilage of your fresh produce, do not store ethylene producing fruits and vegetables with those that are ethylene sensitive. Refer to the chart on page 23.

Frozen Food Storage

reezer storage: Wrap foods in material designed for

frozen food storage. The wrap must seal out air and moisture. Do not refreeze thawed meats.

Ice cream: The firmness of the ice cream will depend on its cream content. Higher quality ice creams usually have a higher cream content, requiring colder freezer temperatures to maintain their firmness. Soft ice cream is not always an indication of a temperature problem.

Make sure your refrigerator and freezer doors close freely and completely. Overloading will affect temperatures inside the unit. Do not fill your freezer with large quantities of unfrozen foods expecting them to fast freeze. Give the freezer ample time to circulate cold air around unfrozen items before adding additional items.

SUGGESTED FOOD STORAGE

The food storage charts on the following pages give you specific information to help you keep food safe and keep it at its best quality. The recommended storage temperatures will help you determine optimal storage conditions for your food. As a general rule, food that is handled properly and kept at temperatures below 40˚F (4˚C) will be safe to eat.

Storing food at temperatures below 40˚F (4˚C) keeps it out of the Danger Zone. The storage times for refrigeration will help keep food from spoiling or becoming dangerous to eat. The time limits for frozen foods are to maintain flavor and texture. Food kept frozen longer than the recommended time will still be safe to eat, but its quality may diminish.

Wash and dry most fruits, and store in the crisper compartment. (Do not wash berries and cherries until you are ready to use them, however.)

Most fruits should be stored in lower humidity.

Fully ripe fruits should be stored in the refrigerator at recommended temperatures to slow down the ripening process.

To hasten the ripening process, you can place unripe fruit in a paper bag that has holes poked in it. Close the bag and set it on a counter. The fruit will produce ethylene, a gas that initiates the ripening process. Check the bag each day.

Discard any fresh fruits that are moldy or have other signs of spoilage and wipe out the refrigerator compartment.

Frequently Asked Questions

ICE PRODUCTION

IMPORTANT NOTE:

is on. The ice bucket icon will be visible in the exterior temperature display if the ice maker system is on. If it is not on, use the ICE MAKER key pad on the control panel to turn on power to the ice maker system.

IMPORTANT NOTE: Dispose of the first bucket of ice

produced by your new unit to ensure that pipe residue or other particles associated with new water lines are not consumed.

Q: My ice maker isn’t producing very much ice.

A: On average, you can expect a cycle of ice (eight cubes

per cycle) every two hours.

Q: My ice is freezing together and clumping.

A: If ice is not used regularly it tends to fuse together.

You may need to discard the ice and allow ice to be replenished.

Q: My ice tastes funny and is discolored.

A: The PRO 48 has a water filtration system built into the

ice maker water line. The water filter cartridge should be replaced if the unit has been turned off for one month or more, or if the water filter cartridge has been in use for more than one year. Contact a plumber or water treatment contractor to discuss options for other source water condition problems.

NOISE

Q: Why do I hear my unit running constantly?

A: It is normal to hear the operation of fans and motors.

Sounds will be accentuated based on the placement of the unit and overall room design.

Make sure that the ice maker system

TEMPERATURE

IMPORTANT NOTE:

make sure the power for your unit is on. If the unit is not on, OFF will be visible in the exterior temperature display. Use the POWER key pad on the control panel to turn on power to the unit.

Q: How do I adjust the temperatures?

A: To adjust temperatures, refer to Temperature Control,

page 6.

Q: What are the suggested temperature settings?

A: The recommended settings are 38˚F (3˚C) for the refrig-

erator section and 0˚F (-18˚C) for the freezer section.

Q: Condensation is forming on the inside and outside of

my unit.

A: In climates with higher humidity, condensation will form

and is considered normal. Leaving the door open for a long period of time may also contribute to condensation forming on the inside your unit.

Q: My unit isn’t cooling properly.

A: Clean the condenser area as outlined on page 13.

DOOR OPERATION

Q: Why is my door hard to open?

A: Your unit was designed for an airtight seal. A vacuum

seal can form after the door is closed. Wait several seconds for pressure to equalize before reopening the door.

Q: The door on my unit is opening too fast and hitting the

wall or surrounding cabinets.

A: The unit may not be leveled properly or a door stop

may be required. Contact your Sub-Zero dealer for details on the door stop kit.
