II. RECEIPT INSPECTION

III. INSTALLATION (continued)

All Traulsen products are factory tested for performance
and are free from defects when shipped. The utmost
care has been taken in crating this product to protect
against damage in transit. All interior fittings have been
carefully secured and the legs or casters are boxed and
strapped inside to prevent damage. Door keys will be
attached to the handle with a nylon strip. The handle is
protected by an easily removable nylon netting.

You should carefully inspect your Traulsen unit for
damage during delivery. If damage is detected, you
should save all the crating materials and make note on
the carrier’s Bill Of Lading describing this. A freight claim
should be filed immediately. If damage is subsequently
noted during or immediately after installation, contact
the respective carrier and file a freight claim. Under no
condition may a damaged unit be returned to Traulsen.
without first obtaining written permission (return
authorization).

III. INSTALLATION

III. a - LOCATION:
Select a proper location for your Traulsen unit, away from
extreme heat or cold. Allow enough clearance between
the unit and the side wall in order to make use of the
door stay open feature at 120° (self-closing feature
operates up to 90°). The door(s) must be able to open a
minimum of 90° in order to make use of the maximum
clear door width available.

III. b - PACKAGING (cont’d):
WARNING: Read and review these instructions, in their
entirety, BEFORE attempting to disassemble and remove
the interior bracing. If either of the diagonal or upper
ceiling braces are dropped, they could cause personal
injury or damage to the equipment.

To disassemble the bracing, first open the doors and
carefully remove the banding that holds the two
diagonal braces together.

WARNING: The diagonal braces will now be loose and
can fall out of position and possibly permit the ceiling
corner brace to fall.

Carefull remove one diagonal brace while supporting the
ceiling corner brace, so that it does not fall (see figure

1). Next, remove the ceiling brace, the remaining
diagonal brace, and lastly the floor brace - then discard.
Repeat as necessary for each section of the unit.

III. b - PACKAGING:
All Traulsen units are shipped from the factory bolted to
a sturdy wooden pallet and packaged in a durable
cardboard container. The carton is attached to the
wooden skid with the use of large staples. These should
first be removed to avoid scratching the unit when
lifting off the crate.

Most exterior stainless steel surfaces have a protective
vinyl covering to prevent scratching during
manufacturing, shipping and installation. After the unit
is installed in place of service, remove and discard the
covering from all surfaces.

To remove the wooden pallet, first if at all possible, we
suggest that the cabinet remain bolted to the pallet
during all transportation to the point of final installation.
The bolts can then be removed with a 3/4” socket
wrench. Avoid laying the unit on its front, side or back
for removal of the pallet.

NOTE: Traulsen does not recommend laying the unit
down on its front, side or back. However, if you must
please be certain to allow the unit to remain in an
upright position afterwards for 24 hours before plugging
it in so that the compressor oils and refrigerant may
settle.

Roll-Thru models also include special interior wood
bracing, intended to protect the cabinet during shipment.
This bracing should under no circumstances be removed
prior to the unit being installed in its final location.

Fig. 1

III. c - INSTALLING LEGS OR CASTERS:
6” high stainless steel legs are supplied standard for all
Traulsen reach-in and pass-thru units. Casters in lieu
of legs are available as an optional accessory for the
same models. These are shipped from the factory
packed inside a cardboard box which is strapped to one
of the shelves. Remove the nylon strap and open the
box, it should contain either four (4) legs or four (4)
casters and sixteen (16) bolts.

WARNING: THE CABINET MUST BE BLOCKED AND
STABLE BEFORE INSTALLING LEGS OR CASTERS.

To install the legs or casters, first raise and block the
reach-in a minimum of 7” from the floor. For
installing legs, thread the legs into the threaded holes
on the bottom of the cabinet (see figure 2). Be certain
that all legs are tightly secured (legs and casters should
be tightened to 300 inch/pounds, max). When the unit
is set in its final position, it is important for proper op­eration that the unit be level. The legs are adjustable for
this purpose, turn the bottom of the leg counter­clockwise to raise it, clockwise to lower it. Level the
unit from front to back as well as side to side in this
manner, using a level placed in the bottom of the

III. d - SHELF PINS:
The unit is supplied with shelves and shelf pins installed.
Check all shelf pins to assure they are tightened down
as they may have come loose during shipping. Rotate
the pins clockwise until they are secured against the
side of the cabinet.

III. e - ROLL-IN MODEL INSTALLATION:
Roll-In cabinets set on the floor require the floor area to
be flat and level. In addition, after the cabinet is set in
place, sealant should be used around the perimeter of
the base to comply with National Sanitation Foundation
requirements (see figure 4). After sealing the unit, the
enclosed ramp should then be installed.

III. e - ROLL-IN MODEL INSTALLATION (cont’d):
facilitate rolling in racks. It is shipped wrapped in brown
paper and secured to the rack guides inside the
cabinet. To secure it in place, remove the two thumb
screws in the breaker strip near the bottom door
opening. Next, loosen the thumb screws located along
the floor at the threshold. Place the ramp(s) on top of
the loosened thumb screws and secure tabs on each
end to breaker strips with thumb screws previously
removed. After installing the ramp(s), it too should be
sealed to the floor.

Bumper strips are secured to the back of Roll-In models
with thumb screws. Loosen these and make them
finger tight to conform with the requirements of the
National Sanitation Foundation (NSF).

III. f -

ATTACHING DOUBLE DEPTH UNITS TOGETHER:
Double depth roll-in/roll-thru units are shipped as two
separate components which must be attached together
at the jobsite. To accomplish this, first, place the front
and rear cabinets in close proximity to each other being
careful to align the drain from the front of the rear unit
to the drain of the front unit. It will be necessary to level
both units together at this time.

Next, using two pipe clamps, pull the units together (see
figure 5). Install the covers over the gap formed between
the units From inside the cabinets, using the screws
provided, install the breaker strips using the strip as a
template.

III. g - INSTALLING THE CONDENSATE EVAPORATOR:
A condensate evaporator is normally supplied on all
self-contained models (remote models require provision
of either a floor drain or an optional electric condensate
evaporator). On those models supplied with a
top-mounted evaporator coil compartment, the
condensate evaporator is also secured to the top of the
cabinet. Check that the condensate pan is properly
located underneath the drain tube.

III. INSTALLATION (continued)

III. g - INSTALLING THE CONDENSATE EVAP (cont’d):
NOTE: Some models, such as single section dual­temperature refrigerator/freezers, are supplied with a
bottom-mounted electric condensate evaporator. This
is shipped in a cardboard carton secured to the cabinet
interior, and must be PROPERLY installed prior to use
(see instructions supplied with the condensate
evaporator).

After the cabinet has been uncrated and the legs/
casters attached, you must install the bottom-mounted
electric condensate evaporator. Locate the four (4) holes
on the exterior bottom towards the rear of the cabinet.
Then, using the four (4) plastic push pins provided, at­tach the mounting rails to the cabinet bottom (the end
flange is to be up and be facing towards the cabinet rear).
Next, place the heater into the heater bracket (note the
enclosed springs are only to be used when the heater is
placed on the floor). Slide heater and bracket into the
mounting rails. Plug the supplied cord into both the
heater on one end, and the electrical outlet provided on
the cabinet exterior bottom towards the front (see
figure 6). Screw the “U-Trap” on to the drain line
located on the rear of the cabinet and then screw the
drain extension into the “U-Trap.”

III. h - REMOTE INSTALLATION (cont’d):
must be done in accordance with good practice and
local regulations. See section “III. g” for information
concerning condensate removal for remote models.

III. i - CORD & PLUG:
Most self-contained models are supplied with a cord &
plug attached. It is shipped coiled at the top of the
cabinet, secured by a nylon strip. For your safety and
protection, all units supplied with a cord and plug
include a special three-prong grounding plug on the
service cord. Select only a dedicated electrical outlet with
grounding plug for power source. NOTE: Do not under
any circumstances, cut or remove the round grounding
prong from the plug, or use an extension cord.

III. j -

POWER SUPPLY:
The supply voltage should be checked prior to
connection to be certain that proper voltage for the
cabinet wiring is available (refer to the serial tag to
determine correct unit voltage). Make connections in
accordance with local electrical codes. Use qualified
electricians.

Use of a separate, dedicated circuit is required. Size
wiring to handle indicated load and provide necessary
overcurrent protector in circuit (see amperage
requirements on the unit’s serial tag).

Fig. 6

NOTE: The use of the “U-TRAP” supplied is required.
Failure to use this component may allow cold air to
migrate down the drain line, resulting in condensation
on the rear of the cabinet.

A remote model is normally supplied configured for
condensate to be run to a floor drain unless purchased
with a condensate evaporator. The installer is
responsible for making the required extension to the
floor drain in accordance with good practice and local
regulations.

III. h - REMOTE INSTALLATION:
Remote models are supplied without compressors,
solenoid valves, etc. The correct voltage, amp listing
and refrigerant are listed on the units serial tag. It is the
responsibility of the installer to specify and supply the
correct size compressor(s) based upon this information
and on-site requirements. Refrigerant line installation

III. k - WIRING DIAGRAM:
Refer to the wiring diagram for any service work
performed on the unit. Should you require one, please
contact Traulsen Service at [phone], and provide
the model and serial number of the unit involved.

III. l - CLEARANCE:
In order to assure optimum performance, the
condensing unit of your Traulsen unit MUST have an
adequate supply of air for cooling purposes. Therefore,
the operating location must either have a minimum of
12” clearance overhead of the condensing unit or allow
for unrestricted air flow at the back of the unit.
Clearance of at least 12” above is required in order to
perform certain maintenance tasks.

IV. OPERATION

IV. a - REFRIGERATORS:
Both refrigerators and freezers do not require manual
defrosting. During normal operation, a refrigerator
continuosly circulates above freezing cabinet air through
the coil. A compressor “OFF” cycle occurs

every hour to

melt any frost which may accumulate on the coil during the
compressor “ON” cycle. The control will read “dEF” when
this occurs and the evaporator fans will continue to operate.
With standard holding refrigerators, high relative humidity is
also maintained to prevent dehydration of stored product.

IV. b -

FREEZERS:
During normal operation, a freezer continuously circulates
below freezing cabinet air through the coil. The coil requires a

IV. c- HOT FOOD CABINETS:
Hot food cabinet operation is governed by the
INTELA-TRAUL control, which controls the ON/OFF
operation of the strip heaters. The control can bet set to
maintain any operational temperature between 140 - 180
F (in 5°F increments).

Hot food cabinets are delivered from the factory with
the control set to the “OFF” position. Follow the
instructions in section “VII. t” to get started.

NOTE: A vent is included at the top of all hot food
cabinets. The vent opening is factory set and secured
for best position. Be certain to make sure this vent is
kept free of any obstruction.

periodic defrosting for proper operation. This is accomplished
by an automatic, time activated, temperature/time terminated,
defrost program. The controller is preset at the factory for six
equally spaced defrost cycles within each 24-hour period.

At the start of a freezer defrost cycle, both the compressor
and evaporator fans are OFF. The INTELA-TRAUL® control will
read “dEF” (see figure 7). The electric heater (attached to the
coil) is energized. When a temperature device affixed to the
coil senses 70°F (models with electric defrost), the coil is fully
defrosted and the compressor operation is resumed, defrost
heaters are automatically turned off. The coil fans are delayed
from starting at the termination of a defrost cycle. Fan
operation is automatically resumed, or they can also be started
by a time or temp delay (whichever comes first). In case of
temp delay, it uses the same coil sensor and starts at 32°F.
The total refrigeration system operation is then resumed.

V. a - CLEANING THE CONDENSER:
The most important thing you can do to insure a long,
reliable service life for your Traulsen is to regularly clean
the condenser coil.

The condensing unit requires regularly scheduled
cleaning to keep the finned condenser clean of lint and
dust accummulation. The INTELA-TRAUL control will
notify you through a “CLN-FIL” message when
cleaning is necessary (see page 8). Keeping the
condenser clean allows the cabinet to operate more

During freezer defrost operation, heat is confined to the coil
enclosure to prevent any significant rise in temperature within
the food zone. The fan delay controls function upon
termination of a defrost cycle is two-fold. First, to prevent
blowing warm air into the food storage area. Second, to
prevent any condensation on the defrost coil from being blown
into the food storage area.

The INTELA-TRAUL® control is set from the factory to
terminate defrost at 20 minutes in the event of a sensor
failure. This setting should never be tampered with, without
first consulting the factory.

V. b - HINGE REPLACEMENT:
Both the door and hinge can be easily removed from the
cabinet. To remove the door, remove the plug at the
bottom of the top hinge. Inside the hinge there is a small
screw which secures the door in place. Remove this
with a flat head screwdriver and the door can then be
lifted off the hinge. To remove the door portion of the
hinge from the door, lift off the hinge cover and then
remove the three Phillips head screws which secure the
hinge in place on the door. To remove the cabinet
portion of the hinge, remove the three Phillips head
screws which hold it in place. On solid door units, the
top hinge(s) contains a microswitch for controlling the
interior lighting.

To reassemble the hinge reverse the previous procedure.

V. d - CLEANING THE EXTERIOR:
Exterior stainless steel should be cleaned with warm
water, mild soap and a soft cloth. Apply with a
dampened cloth and wipe in the direction of the metal
grain.

Avoid the use of strong detergents and gritty, abrasive
cleaners as they may tend to mar and scratch the
surface. Do NOT use cleansers containing chlorine, this
may promote corrosion of the stainless steel.

Care should also be taken to avoid splashing the unit
with water, containing chlorinated cleansers, when
mopping the floor around the unit.

For stubborn odor spills, use baking soda and water
(mixed to a 1 TBSP baking soda to 1 pint water ratio).

V. e - CLEANING THE INTERIOR:
For cleaning both stainless steel and anodized
aluminum interiors, the use of baking soda as described
in section “V. d” is recommended. Use on breaker strips
as well as door gaskets. All interior fittings are
removable without tools to facilitate cleaning.

V. f - ADJUSTING THE SHELVES:
For shelves mounted on pins, first select the desired
location and remove the white plastic covers in the
interior back and sides by rotating them counter­clockwise. Remove the shelf pins by rotating them
counter- clockwise. Install the pins in the desired
location by rotating clockwise. Make sure the pin is
securely tightened down. Do not over tighten. Slide the
shelf into its new position, and replace the white plastic
covers into the holes vacated by the shelf pins.

V. CARE & MAINTENANCE (cont’d) VI. OTHER

V. g - REPLACING THE LIGHT BULB:
All Traulsen R & A Series models are supplied with
incandecent lighting unless optional fluorescent
lighting was ordered (except for sliding glass door
models for which fluorescent lights are supplied
standard).

The bulb is a 115 volt/40 watt, T-61⁄2 intermediate clear
refrigerator lamp. It is mounted at the top front of the
cabinet at the center, and is located behind a plastic light
cover on refrigerator and freezer model.

Heated units (RHF/AHF/RIH/AIH/RDH/ADH/RIDH/AIDH)
are equipped with a similar type bulb, however this is
shatterproof because these models do not include a
plastic light cover.

To replace the bulb, first remove the light cover (if so
equipped). This can be accomplished by squeezing it
together on both sides until it comes free. Replace the
light bulb, then squeeze both sides of the light cover
together and replace in its original position.

V. h - REPLACING THE OPTIONAL CONDENSER FILTER:
Some Traulsen R & A Series models are supplied with
an optional filter screen for the condenser coil. This is
located behind the louver assembly, and must be cleaned
at least once a month, or more frequently if needed, to
insure proper equipment operation.

To clean the condenser filter, first disconnect electrical
power to the cabinet and lift up the front louver
assembly. To lift this, remove the two screws located
on both sides at the bottom of the louver assembly. The
filter is located on the face of the condenser coil, and
can simply lifts up and away for cleaning (see figure 12).

VII. n - SETTING THE DEFROST LOCKOUTS:

The defrost lockout parameters allow the customer to prevent the unit from going into a defrost cycle for
two hours during a set timeframe. Customers can set up to four defrost lockout parameters. They are all
programmed the same way. The parameters will be set for the time the lockout is to start. The controller
automatically calculates 2 hours from that setting. The options are similar to the 24-hour clock settings
and are in 30-minute increments. Each of the lockout parameters covers 6 hours of the 24-hour clock.
Note: The 24-hour clock must be set for this feature to operate at the correct time of day. See “Setting

the 24-Hour Clock” on page 14.

* Denotes not available.

A lockout cannot be programmed to start at 12:00 a.m. or 12:30 a.m. due to conflicts with other
internal programs. The defrost lockouts cannot be programmed to run back-to-back. For example, if
dL1 is set to 080, then a defrost cycle would be locked out from 8:00 a.m. to 10:00 a.m. Because of
the dL1 setting the dL2 parameter would not let the user choose a lockout start time before 10:30
a.m. All lockouts are preset at the factory to OFF.

XII. STAINLESS STEEL OVERVIEW

XII. a ­All Traulsen R & A Series Refrigerator, Freezer, Dual­Temp and Heated Cabinet models are constructed with
a high quality 430 series, 20 gauge stainless steel
exterior finish (front, sides and doors). The interior
finish on these same R-Series models are constructed
using 300 series stainless steel (anodized aluminum is
used for A-Series).

The stainless steel finish on Traulsen R & A Series should
retain its appearance throughout the products usable
lifetime. However, some care is required to maintain this
appearance. The following paragraphs will provide a
guideline on proper care of the exterior/interior finish,
as well as some suggestions on how to repair a finish
which has been marred due to adverse environmental
conditions or improper jobsite care.

XII. b ­The process by which stainless steel retains its
appearance is a result of its type of metal alloy. Steel is
a composite of metals combined in a specific industrial
process. Stainless steel contains a high percentage of
chromium, the addition of which provides both its
appearance, and a microscopic surface layer protecting
the steel underneath from corrosion. This external layer
acts as a barrier, preventing typical oxidation of the steel.
Remove this barrier, and the environment will
eventually corrode the metal, marring its appearance.

XII. c - UNDERSTANDING THE CAUSES OF CORROSION:
Corrosion to stainless steel can only be caused in one
of four specific ways:

1) ABRASION
Abrasion can be caused during routine cleaning of the
metal, either by use of an abrasive cleanser, or use of an
abrasive device, such as a metal scouring pad.
Abrasion can also be caused by contact with other hard
surfaces, such as nearby equipment, walls or tools.
Special care should be taken to position your unit
properly to prevent accidental dents and scratches.

2) WATER
Water everywhere contains various deposits, or solids,
which as the water drys or evaporates, can leave spots
behind. The spots may eventually cause corrosion if
not removed.

3) CHEMICALS OR WATER CONTAINING CHLORIDES
Chlorides, such as found in water or many cleaning
materials are especially corrosive to stainless steel.
Daily janitorial duties, such a floor mopping, can splash
water containing chlorinated cleansers against the front
and sides of a Traulsen refrigeration product, resulting
in corrosion. Avoid use of these on or around a Traulsen
refrigeration product if at all possible.

4) PROLONGED CONTACT WITH FOOD PRODUCT
Many food products, such as milk and carbonated
sodas,contain acids which may damage the protective
layer of stainless steel. All food and beverage spills

INTRODUCTION:

STAINLESS STEEL, HOW IT WORKS:

XII. c - UNDERSTANDING THE CAUSES OF CORROSION:
should be cleaned up promptly to avoid possible stains
and corrosion.

XIII. CARE OF STAINLESS STEEL

XIII. a - USING THE PROPER TOOLS:
Use of proper cleaning materials will do much to
prolong the appearance of your Traulsen refrigeration
product. We particularly encourage the use of either
plastic scouring pads or soft cloths for cleaning
stainless steel.

Soft nylon scouring pads can also be used, however care
has to used to insure that all scrubbing is done in the
direction of the metals “GRAIN.” Because metals are
chrystalline in nature, when they are in a solid state the
individual ions line up to form visible grain lines. Use of
a soft nylon scouring pad in a direction opposite of the
grain will mar its luster. Always do so “PARALLEL” to
the grain.

There are several types of tools which should NEVER
BE USED when cleaning stainless steel, these include:

• WIRE BRUSHES

• METAL SCOURING PADS

• SANDPAPER

• SCRAPERS & PUTTY KNIVES

Use of any of these tools will result in scratches or
removal of the stainless steel’s protective layer, which
will eventually lead to corrosion and rust.

XIII. b - USING THE RIGHT CLEANSER:
Avoid all cleaning products containing chloride
ingredients. Use of a cleanser specifically designed for
stainless steel is highly recommended. You may find
yourself in a situation where you are uncertain if a
particular cleaning product contains any chlorides. If
unsure, its probably best to just assume that it does and
avoid its use in cleaning a Traulsen refrigeration
product.

Also to be avoided are cleaning products which contain
“QUATERNARY SALTS.” These salts can literally
attack the stainless steel’s protective layer, leading to
corrosion and pitting of the steels surface.

After cleaning, it is important to always rinse the cleaned
area thoroughly with cool, clean water (do not use hot
water) and wipe completely dry using a paper towel or
soft absorbent cloth.

Use of cleaning products designed for use on stainless
steel, in conjunction with the proper tools, as outlined
above will help retain the appearance of your Traulsen
refrigeration product for years and years.

XIII. CARE OF STAINLESS STEEL

(cont’d)

XIII. c - CLEANING SUMMARY - DO’S & DONT’S:
To summarize the proper cleaning of Traulsen
refrigeration products, always follow the below
guidelines.

DO use only cleaning products designed for

stainless steel, or cleaning products which do
not contain chlorides.

DO use only non-abrasive cleaning materials, such

as soft cloths or plastic scouring pads.

DO clean-up food and beverage spills ASAP.

DO scrub only in the direction of the grain when

using soft nylon scouring pads.

DON’T use chlorinated cleansers or cleansers

containing quaternary salts.

DON’T use abrasive cleaning materials or tools

which can scratch the stainless steel’s surface.

XIII. d ­In the daily routine of a busy foodservice operation, your
Traulsen refrigeration product may occasionally come
in contact with chlorinated cleaners, such as when
being splashed during mopping. Stain and corrosion
problems resulting from this can be avoided by prompt
action to remove this cleanser. Rinse the affected area(s)
thoroughly with cool, clean water (do not use hot water)
and wipe completely dry using a paper towel or soft
absorbent cloth.

XIII. e - PROTECTING THE STAINLESS STEEL SURFACE:
Occasional use of a commercial stainless steel polish,
such as “Sheila Shine,” will help protect the surface of
stainless steel. Follow the directions on the spray can
for proper use.

DEALING WITH ACCIDENTAL CHLORIDE CONTACT

XIV. CORROSION REMEDIES

XIV. CORROSION REMEDIES

XIV. a - DEALING WITH RUST AFTER THE FACT (cont’d):
STEP THREE - Apply a preservative polish, such as
“Sheila Shine,” to the affected area (see section II. e).

XIV. b - DEALING WITH EXTREME RUST SITUATIONS:
In the event that rust and corrosion were not dealt with
promptly, more acute situations can be remedied as
follows:

NOTE: PROCEDURE REQUIRES USE OF AN ACID
BASED SOLUTION - USE OF PROTECTIVE GLOVES AND
EYEWEAR ARE REQUIRED BEFORE PROCEEDING

STEP ONE - In a clean spray bottle combine water with
“Zep FS Lime Remover” to make a 5 parts to 1 solution.

STEP TWO - Apply this solution to the affected area with
either a clean cloth or sponge.

STEP THREE - After application, wipe the same area
thoroughly clean with water only to remove any
residue.

:

STEP FOUR - Once cleaned, apply a light coat of “Zep
Restore” to the surface area. This will serve to preserve
the metal and help prevent future rust from occuring.

STEP FIVE - Restore the remaining stainless steel
surfaces to their original shine using “Zep Stainless
Steel Polish.”

Repeat steps one thru five if necessary for stubborn rust
and corrosion areas.

XIV. c ­There are several products available on the market
today which can actually help restore the
“PASSIVATION” of stainless steel. “PASSIVATION”
refers to the protective qualities of the non-reactive
surface layer of stainless steel which prevents
oxidation. Contact your cleaning supplier for product
recommendations and more information.

RESTORING THE PROTECTIVE LAYER:

XIV. a - DEALING WITH RUST AFTER THE FACT:
Although Traulsen strongly recommends proper care
and cleaning of stainless steel finishes in order to avoid
rust and corrosion before it occurs, we recognize that it
may occur occasionally as a result of the causes
described in section one of this booklet.

To remove small quantities of rust from the surface of
stainless steel, it is far preferable to deal with this when
it first becomes visible. When rust occurs, do not allow
it to remain for any period of time, and remove it using
the following method:

STEP ONE - Use a lightly abrasive compound (free of
harmful chlorides), such as “Bon Ami,” on a soft cloth,
to remove the rust. Care must be taken to rub this on
the area of rust only in the direction of the stainless
steel’s grain.

STEP TWO - Once the rust is removed, clean the affected
area thoroughly with a stainless steel cleaner (see
sections II. a & b).
