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 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 & Co. 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. c - INSTALLING LEGS OR CASTERS:
Adjustable 6” high legs are supplied standard for all
Traulsen G-Express 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) legs.
Casters in lieu of legs 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) 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 1). Be certain
that all legs are tightly secured. 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 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 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.
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 firmly to the cabinet bottom at each corner
(see figure 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 fit 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 flat head screwdriver and the door can then be lifted off the hinge
(see figure 3).
III. e - REMOVING THE DOORS & HARDWARE
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 figure 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) flat 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.
(cont’d)
:
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 figure 4).
III. f - 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. 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 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. 4
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 flow 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-Express 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 onsite installation.
To install additional shelves, first 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
fingers. 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 figure 5).
°F °C
SET
FREEZER
Fig. 5
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 de-
frosted 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 re-
frigeration system operation is then resumed. 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 twofold. 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 first consulting the factory.
-4-
LIGHT SWITCHES:
IV. d All G-Express models (except sliding glass door 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 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 first paragraph.
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.

Screws
V. CARE & MAINTENANCE (cont’d)IV. OPERATION (continued)
V. a - CLEANING THE CONDENSER (cont’d):
Vacuum or brush any dirt, lint or dust from the finned
condenser coil, the compressor and other cooling
system parts. If significant dirt is clogging the condenser fins, use compressed air to blow this clear.
Care should be taken not to bend any of the condenser
fins, as this will reduce performance and compressor
life. Lower louver assembly and replace screws to
hold it in place.
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. c - REPLACING THE GASKETS:
To remove the gasket to be replaced, grasp it firmly
by one corner and pull it out. Before attempting to
install a new gasket, both the unit and the gasket itself must be at room temperature. Insert the four corners first 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 hitting with a mallet until the gasket is completely seated in place (see figure 7 for proper gasket
placement).
Lift-Up Louver
Fig. 6
Assembly
The condensing unit requires regularly scheduled
cleaning to keep the finned condenser clean of lint
and dust accummulation. Keeping the condenser
clean allows the cabinet to operate more efficiently
and use less energy. To clean the condenser, 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 (see figure 5). Once the screws are removed, the panel can be pivoted upwards allowing
full access to the front facing condenser (see figure
6).

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 “Settingthe 24-Hour Clock” on page 11.
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.
Follow the instructions to enter the customer access code on page 8. When the control
displays Thermostat Set High, press the down arrow key until the control the

VII. MICROPROCESSOR CONTROL (continued)
VII. o - ADJUSTING THE ROOM TEMPERATURE OFFSET:
The room temperature offset parameter allows a service technician or end user the ability to have the
display show a temperature that is within three degrees of the actual temperature being read by the
cabinet air sensor. This allows for continuity of reading between different temperature reading devices.
(i.e.: thermistor Vs thermocouple Vs handheld thermometer) This parameter is preset at the factory to
“0” or no offset.
Follow the instructions to enter the customer access code on page 8. When the control displays
Thermostat Set High, press the down arrow key until the control display reads
Room Temperature Offset. Press the set button . Use the arrow keys to adjust the
offset to your desired setting. When the display shows the offset you want press the set button .

keys to scroll to the next parameter or wait 30 seconds for the control to return to normal
operation.
VII. p - VIEWING SENSOR TEMPERATURES:
These parameters allow a service technician or customer to view the temperature of all sensors
within the unit. The temperatures cannot be adjusted.
Follow the instructions to enter the customer access code on page 8. When the control displays
Thermostat Set Point High , press the DOWN arrow key unit the display reads
