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.
You should carefully inspect your 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 the damage. A freight claim should be led
immediately. If damage is subsequently noted during or
immediately after installation, contact our customer care
team to le a freight claim. There is a fteen (15) day limit
to le freight damage with the carrier. Under no condition
may a damaged unit be returned to Traulsen without rst
obtaining written permission (return authorization). You
may contact Hobart/Traulsen customer care at 800-333-
7447 to request a return or le a claim.
III. INSTALLATION
III. a - LOCATION:
Select a proper location for your 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 1200 (self-closing feature operates up to
900). The door(s) must be able to open a minimum of 900
in order to make use of the maximum clear door width.
III. b - PACKAGING:
Your Traulsen unit is shipped from the factory bolted to a
sturdy wooden pallet in stretch wrapped material.
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 application peel, 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 1/2” 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
on its front, side or back. If you must, please allow the
unit to remain in an upright position for 24 hours before
plugging it in so that the compressor oils and refrigerant
may settle.
III. c - INSTALLING/ADJUSTING LEGS OR CASTERS:
To install legs or casters, slide leg or caster into the caster
channel from the side of the unit without the refrigeration
system.
To adjust the legs or casters, loosen the two bolts and move
leg or caster to desired location, spacing between leg or caster
not to exceed 48 inches. Leg or caster on each end of the unit
can not exceed 8 inches from the end of the cabinet.
NOTE: Traulsen recommends to position legs or casters under
the mullion when possible.
CASTER CHANNEL
BOLT
CASTER PLATE
III. d - CORD & PLUG:
All self-contained models are shipped standard with a NEMA
5-15P plug and 9 foot cord . Select only a dedicated electrical
outlet 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. e - 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, see
page 1). 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).

IV. OPERATION
V. CARE & MAINTENANCE
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 2 1/2 Hours
for 20 minutes to melt any frost which may accumulate
on the coil during the compressor “ON” cycle. The control
will read “dEF” and the green water drop will be illuminated. With standard holding refrigerators, high relative
humidity is also maintained to prevent dehydration of
stored product.
INTELA-TRAUL
°F °C
FREEZER
SET
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, utilizing
hot gas from the refrigeration system. The controller is
preset at the factory for six equally spaced defrost cycles
within each 24-hour period.
IV. b - FREEZERS (continued):
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 control 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 terminated defrost at 20 minutes in the event of sensor failure.
This setting should never be tampered with, without rst
consulting Traulsen’s Technical Service department.
V. a - CLEANING THE CONDENSER/FILTER:
The most important thing you can do to insure a long,
reliable service life for your Traulsen is to regularly clean
the condenser coil and or lter if provided.
The microprocessor control will notify you through a
“CLN-FIL” message when the condensing temperature of
the refrigerator reaches 140 degrees F or greater. If the
condensing temperature reaches 160 degrees F the compressor will automatically turn o . When the temperature
drops below 140 degrees F the compressor will restart
and when the temperature drops below 120 degrees F
the alarm will reset.
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY
BEFORE CLEANING ANY PARTS OF THE UNIT.
At the start of a freezer defrost cycle, the compressor,
condenser fan and evaporator fan shut o. The hot gas
relay will be energized, this will energize the hot gas
solenoid valve thru the normally open contacts and the
condenser fan circuit will be de-energized thru the (normally closed contacts), and the compressor will restart.
When the evaporator coil sensor reaches 400 F the coil is
fully defrosted or if the maximum time of defrost duration (20 minutes) is reached (which ever comes rst) then
the defrost hot gas relay is de-energized. The condenser
fan restarts and the hot gas solenoid valve closes, The
compressor system returns to the cooling mode. Total
refrigeration system operation is then resumed (green
snowake icon goes out) and the display will show def
for an additional 10 minutes then return to reading the
inside cabinet temperature. The evaporator fan(s) are
delayed from starting at the termination of the defrost
cycle and will automatically resume by time or temp delay
(5 minutes or 300 F coil sensor temperature, whichever
comes rst ).
To clean the condenser/lter, rst disconnect electrical
power to the cabinet and remove the front louver assembly. To do so, place hands under the louver panel and
pull out and up to get louver panel o bracket of the unit.
See diagram below.
Proceed to vacuum or brush any dirt, lint or dust from
the nned condenser coil/lter, the compressor and other
cooling system parts. If signicant dirt is clogging the condenser ns or lter, use compressed air to blow this clear.
To replace the louver assembly reverse the process.

V. CARE & MAINTENANCE-(continued) VI. DRAWERS
V. b - 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 the gasket itself 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 hitting with a mallet until the gasket
is completely seated in place (see gure below for proper
gasket placement).
NOTE: The gasket may appear too large, but if it is installed
as indicated above it will slip into place.

VI. a - REMOVING THE DOOR AND INSTALLING
DRAWERS:
Doors are supplied standard on all TU Series Full-Size Undercounter models. However, we have engineered our
models with a drop-in feature that allows you to easily
convert door(s) into two 6” deep drawers or three 4” deep
drawers.
The door(s) on all models can easily be converted to drawers in the eld. To begin the process, open the door to
its maximum position. Support the non-hinged end of
the door so minimum movement occurs. When the bolts
from the lower hinge plate are removed, remove the lower
hinge plate and then the door from the top hinge bracket
plate and then the door from the top hinge bracket. The
hinge plate pin and plastic bushing will remain in the top
hinge plate.
NOTE: The lower hinge plate is under spring tension.
Once the door(s) have been removed, Insert drawer frame
as shown below.
V. c - CLEANING THE CABINET SURFACES:
WARNING: DISCONNECT ELECTRICAL POWER SUPPLY
BEFORE CLEANING ANY PARTS OF THE UNIT.
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, such as bleach, 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 or spills, use baking soda and water (mixed
to a 1 tbsp baking soda to 1 pint water ratio).
A stainless steel polish is recommended for shining of unit.
Once the drawer frame has been inserted, the drawer frame
module can be installed by tighting the black front and back
clamping knobs (2 of each) located on the cross rail locks
and liner locks. Slide the front cross rail locks towards the
center of the drawer frame module and allow the liner locks
to drop down from the top of the liner. Insert the door frame
module push towards the back of the unit. The entire frame
assembly is now installed and ready for use.
NOTE: Repeat process for multiple drawer(s) inserts.

A lockout can not be programmed to start at 12:00 am or 12:30 am due to conicts with other internal programs. The defrost lockouts can not 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 am to 10:00 am. Because of the dL1 setting the dL2 parameter would not let the user choose a
lockout start time before 10:30 am. All lockouts are preset at the factory to OFF.
