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 ttings
have been carefully secured and the legs 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 led immediately. If damage is subsequently noted during or immediately after installation,
contact the respective carrier and le a freight claim.
Under no condition may a damaged unit be returned to
Traulsen & Co. without rst 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. c - INSTALLING CASTERS OR LEGS:
A set of four (4) 6” high casters are supplied standard
for all Traulsen G-Series units. These are shipped
from the factory packed inside a cardboard box which
is strapped inside the cabinet to the lower shelf.
Inside it should contain four (4) casters and sixteen
(16) bolts.
Legs in lieu of casters are available as an optional
accessory kit for the same models. These are shipped
inside a separate cardboard box. Inside it should
contain four (4) legs.
WARNING: THE CABINET MUST BE BLOCKED AND
STABLE BEFORE INSTALLING LEGS OR CASTERS.
To install the legs or casters, rst raise and block the
reach-in a minimum of 7” from the oor. For installing legs, thread the legs into the threaded holes on the
bottom of the cabinet (see gure 1). Be certain that
all legs are tightly secured. When the unit is set in
its nal 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 cabinet.
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 rst 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, rst if at all possible, we
suggest that the cabinet remain bolted to the pallet
during all transportation to the point of nal 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.
Fig. 1
Please note that Traulsen units are not designed to be
moved while on legs. If the unit requires moving, a pallet jack or forklift should be used to prevent damage.
For installing casters, the casters are “plate” type,
and require the use of four (4) bolts each to secure
them rmly to the cabinet bottom at each corner (see
gure 2). The caster bolts are tightened using a 1/2”
socket wrench.

III. INSTALLATION (continued)
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 - REMOVING THE DOORS & HARDWARE:
In order to t through narrow (less than 35”) doorways, it may be sometimes be necessary to remove
the door(s), and/or hinges. To remove any solid door,
begin by removing 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 at
head screwdriver and the door can then be lifted off
the hinge (see gure 3).
III. e - REMOV I N G THE DOORS & HARDWARE
(cont’d)
If it is also necessary to remove the hinge hardware
from the cabinet as well, begin by removing the three
Phillips head screws which hold it in place. Set these
components aside for later reassembly (see gure
4).
NOTE: All solid door units include a microswitch for
controlling the interior lighting in the top hinge(s).
Special care should be taken to not damage the wiring
for this during the hinge removal process.
The lock keeper will also need to be removed in order
to reduce theroverall cabinet depth to 32”.
Begin by removing the two (2) Phillips head screws
which secure the lock keeper actuator to the lock
keeper bracket.
Next remove the lock keeper bracket by removing the
two (2) at head screws which secure it in place. Set
these components aside for later reassembly.
To re-install the door and/or hinges, please reverse the
appropriate sections of the preceding procedure.
:
Fig. 3
After removing the door, it is now necessary to remove the hinge assembly and hardware from the door
itself.
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 (see gure 4).
III. f - CORD & PLUG:
All G-Series 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. g - 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 qualied
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).
III. h - WIRING DIAGRAM:
Refer to the wiring diagram for any service work performed on the unit. Should you require one, please
contact Traulsen Service at (800) 825-8220, and provide
the model and serial number of the unit involved.

III. INSTALLATION (continued)
IV. OPERATION (continued)
III. i - 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 ow at the back of the unit. Clearance
of at least 12” above is required in order to perform
certain maintenance tasks.
III. j - INSTALLING OPTIONAL INTERIOR KITS:
In addition to their standard interiors, G-Series models also offer the option for additional shelves or tray
slides. If ordered, these are shipped as kits along
with the unit, packaged in a separate cardboard box
which contains all the necessary parts and hardware
for on-site installation.
To install additional shelves, rst remove the white
plastic covers from inside the cabinet. These are located along the same vertical line as the pins already
in place on the interior side walls, back and center
mullion (two and three-section models). This exposes
threaded holes in which you may position the new
shelves. Next insert the gray plastic shelf pins into
these holes and tighten by turning clockwise with your
ngers. After all four pins are in place, the new shelf
should be placed to rest on top of them. The unused
plastic covers may be discarded or saved for future
changes to the cabinet interior.
Installation of optional tray slides varies with each
cabinet, and with each type of tray slide ordered. To
install optional tray slides, follow the directions packaged inside the kit carton.
III. k - ON/OFF SWITCH:
An ON/OFF toggle switch for the power supply is
provided. It is located on top of the unit, mounted to
the side of the evaporator housing. This is shipped
from the factory in the ON position.
IV. OPERATION
IV. a - REFRIGERATORS:
Both refrigerators and freezers do not require manual
defrosting. During normal operation, a refrigerator continuously 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. 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 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 microprocessor control will read “dEF” (see gure 5).
°F °C
SET
FREEZER
Fig. 5
The electric heater (attached to the coil) is energized.
When a temperature device afxed 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 rst). In case of temp delay,
it uses the same coil sensor and starts at 32°F. The
total refrigeration system operation is then resumed.
During freezer defrost operation, heat is conned
to the coil enclosure to prevent any signicant 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 microprocessor 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 rst consulting the factory.

IV. OPERATION (continued)
V. CARE & MAINTENANCE (cont’d)
IV. c - LIGHT SWITCHES:
All G-Series models include a concealed light switch
mounted in the top door hinge(s), which automatically
activates the interior light when the door is opened.
When the door is closed, the lights are not operating.
In addition, on hinged glass door models, an exterior
mounted, illuminated red switch is included for manual
light control. In the ON position, the lights are illuminated whether the doors are open or not. In the OFF
position, the lights are controlled by the hinge switch
as described in the rst paragraph.’
IV. d - SPECIAL DISPLAY OPERATING MODE:
G-Series models built during the summer of 2009 and
beyond will include a special control mode which
disables the external temperature display. Note that
before doing so you must install an interior mounted
thermometer in order to conform with local health
codes.
To initiate this mode press the up and down arrows
simultaneously for 1 second until the temperature
display goes blank. The temperature display will
remain disabled indenately until such time as the
operator wishes to restore normal operation. To do
so simply repeat the process of pressing the up and
down arrows simultaneously for 1 second until the
temperature display illuminates.
Note that in the event power is interrupted for any
reason the display will return to standard operating mode where it displays the correct cabinet air
temperature.
V. CARE & MAINTENANCE
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY BEFORE CLEANING ANY PARTS OF THE UNIT.
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 nned condenser clean of lint and
dust accummulation. Keeping the condenser clean
allows the cabinet to operate more efciently and use
less energy. To clean the condenser, rst 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 as-
sembly (see gure 5). Once the screws are removed,
the panel can be pivoted upwards allowing full access
to the front facing condenser (see gure 6).
Vacuum or brush any dirt, lint or dust from the nned
condenser coil, the compressor and other cooling

system parts. If signicant dirt is clogging the condenser ns, use compressed air to blow this clear.
Care should be taken not to bend any of the condenser
ns, as this will reduce performance and compressor
life. Lower louver assembly and replace screws to
hold it in place.
V. b - HINGE REPLACEMENT:
To remove the door, remove the plug at the bottom of
the top hinge. Behind this is a screw which secures
the door in place. Remove this with a at head screwdriver and then lift the door off the hinge. To remove
the door portion of the hinge, lift off the hinge cover
and then remove the 3 x Phillips head screws which
secure the hinge in place. To remove the cabinet
portion of the hinge, remove the 3 x Phillips head
screws which hold it in place. On solid door units, the
top hinge(s) contains a switch for controlling the lights.
To reassemble the hinge reverse the procedure.
V. c - REPLACING THE GASKETS:
To remove the gasket to be replaced, grasp it rmly
by one corner and pull it out. Before attempting to
install a new gasket, both the unit and gasket must
be at room temperature. Insert the four corners rst
by using a rubber mallet (or hammer with a block
of wood). After the corners are properly inserted,
work your way towards the center from both ends by
gently h itting with a mallet until the gask et is
completely seated in place (see gure 7 for proper
gasket placement).

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 oor 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 anodized aluminum interiors, the use of
baking soda as described in section “V. d” is recommended. Use on breaker strips as well as door gas-
kets. All interior ttings are removable without tools
to facilitate cleaning.
V. f - ADJUSTING THE SHELVES:
For shelves mounted on pins, rst select the desired
location and remove the white plastic covers in the interior back and sides by rotating them counter-clockwise.
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
