III. INSTALLATION (continued)  
All Traulsen products are factory tested for perfor-  
mance 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.  
III. c - INSTALLING LEGS OR CASTERS:  
6high stainless steel legs are supplied standard for  
all Traulsen undercounter units. Casters in lieu of legs  
are available as an optional accessory for the same  
models. These are shipped from the factory packed  
inside two cardboard boxes which are strapped to one  
of the shelves. Remove the nylon straps and open the  
boxes, each should contain either four (4) legs or four  
(4) casters and sixteen (16) bolts (see figure 1 for  
proper locations).  
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 carriers Bill Of Lading describing this. Afreight  
claim should be filed immediately. If damage is sub-  
sequently noted during or immediately after installa-  
tion, contact the respective carrier and file a freight  
claim. Under no condition may a damaged unit be re-  
turned to Traulsen & Co. without first obtaining writ-  
ten 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.  
Fig. 1  
III. b - PACKAGING:  
Proper Leg/Caster Locations  
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.  
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 7from the floor. For install-  
ing 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  
counter-clockwise 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.  
Most exterior stainless steel surfaces have a protec-  
tive vinyl covering to prevent scratching during manu-  
facturing, 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 installa-  
tion. The bolts can then be removed with a 3/4socket  
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 up-  
right position afterwards for 24 hours before plugging  
it in so that the compressor oils and refrigerant may  
settle.

III. d - INSTALLING LEGS OR CASTERS (cont’d):  
III. i - PLACING EQUIPMENT ON TOP OF UNIT:  
Equipment may be placed on top of your Traulsen full-  
size undercounter or equipment stand. However,  
please be aware that a stainless steel worktop is re-  
quired on cabinets being used to support equipment  
weighing in excess of 100 lbs. or producing heat in  
excess of 140°F to the top surface. Optional stainless  
steel tops are available from Traulsen.  
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 dam-  
age. For installing casters, the casters are “plate”  
type, and require the use of four (4) bolts each to se-  
cure them firmly to the cabinet bottom at each corner  
(see figure 3). The caster bolts are tightened using a  
1/2” socket wrench.  
IV. OPERATION  
IV. a - REFRIGERATORS:  
Fig. 3  
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 (see figure  
4). With standard holding refrigerators, high relative  
humidity is also maintained to prevent dehydration of  
stored product.  
III. e - SHELF PINS:  
The unit ships with shelves and shelf pins installed.  
Check all shelf pins to assure they are tightened down  
as they may have come loose during shipping. Ro-  
tate the pins clockwise until they are secured against  
the side of the cabinet.

III. f - CORD & PLUG:  
Most self-contained models are supplied with a cord  
& plug attached. It is shipped coiled at the rear of the  
cabinet, secured by a nylon strip. For your safety and  
protection, all units supplied with a cord and plug in-  
clude a special three-prong grounding plug on the ser-  
vice cord. Select only a dedicated electrical outlet with  
grounding plug for power source. NOTE: Do not un-  
der any circumstances, cut or remove the round  
grounding prong from the plug, or use an extension  
cord.  
Fig. 4  
IV. b - FREEZERS:  
During normal operation, a freezer continuously cir-  
culates below freezing cabinet air through the coil. The  
coil requires a periodic defrosting for proper opera-  
tion. This is accomplished by an automatic, time acti-  
vated, 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.  
III. g - POWER SUPPLY:  
The supply voltage should be checked prior to con-  
nection to be certain that proper voltage for the cabi-  
net wiring is available (refer to the serial tag to deter-  
mine correct unit voltage). Make connections in ac-  
cordance with local electrical codes. Use qualified  
electricians.  
At the start of a freezer defrost cycle, both the com-  
pressor and evaporator fans are OFF. The INTELA-  
TRAUL control will read “dEF” (see figure 4). When a  
temperature device affixed to the coil senses 70°F, the  
coil is fully defrosted and the compressor operation  
is resumed. The coil fans are delayed from starting at  
the termination of a defrost cycle. Fan operation is  
automatically resumed, 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.  
Use of a separate, dedicated circuit is required. Size  
wiring to handle indicated load and provide necessary  
overcurrent protector in circuit (see amperage require-  
ments on the unit’s serial tag).  
III. h - WIRING DIAGRAM:  
Refer to the wiring diagram for any service work per-  
formed on the unit. Should you require one, please  
contact Traulsen Service at (800) 825-8220, and pro-  
vide the model and serial number of the unit involved.  
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 con

V. CARE & MAINTENANCE  
V. c - REPLACING THE GASKETS:  
IV. b - FREEZERS (contd):  
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 5 for proper gasket place-  
trols 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 conden-  
sation 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 sen-  
sor failure. This setting should never be tampered  
with, without first consulting the factory.

V. CARE & MAINTENANCE  
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.  
NOTE: The gasket may appear too large, but if it is  
installed as indicated above it will slip into place.  
V. d - CLEANING THE EXTERIOR:  
The condensing unit requires regularly scheduled  
cleaning to keep the finned condenser clean of lint  
and dust accummulation. The INTELA-TRAUL con-  
trol will notify you through a CLN-FILmessage when  
cleaning is necessary (see page 7). Keeping the con-  
denser clean allows the cabinet to operate more effi-  
ciently and use less energy.  
Exterior stainless steel should be cleaned with warm  
water, mild soap and a soft cloth. Apply with a damp-  
ened cloth and wipe in the direction of the metal grain.  
Avoid the use of strong detergents and gritty, abra-  
sive 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.  
To clean the condenser, first disconnect electrical  
power to the cabinet and remove the front louver as-  
sembly. To remove this, follow the directions in sec-  
tion VI. d - Step #1. Once the screws are removed, the  
panel can be removed allowing full access to the  
powerpack. Vacuum or brush any dirt, lint or dust  
from the finned condenser coil, the compressor and  
other cooling system parts. If significant dirt is clog-  
ging the condenser fins, use compressed air to blow  
this clear.  
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 alumi-  
num interiors, the use of baking soda as described in  
section V. dis recommended. Use on breaker strips  
as well as door gaskets. All interior fittings are re-  
movable without tools to facilitate cleaning.  
Replace louver assembly, screws and caps.  
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. Re-  
move this with a flat head screwdriver and the door  
can then be lifted off the hinge. To remove the door  
half 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 half of the hinge, remove the three Phillips  
head screws which hold it in place. To reassemble  
the hinge reverse the previous procedure.  
WARNING: DISCONNECT ELECTRICAL POWER

VI. c - REMOVING THE DRAWERS:  
Each drawer on UL equipment stand models are de-  
signed to accommodate two (2) 12x 20x 4deep  
pans, front to back. SBS models can acommodate two  
(2) 12x 20x 4deep pans, side by side.  
Drawers are supplied standard with divider bars which  
allow it be configured for use with half, third and quar-  
ter size pans. These are shipped along with the cabi-  
net, taped together and secured inside of the bottom  
drawer. No bar is required for use with full-size pans.  
In all cases, pans are supplied by others.  
The drawers can be easily removed by first pulling the  
drawer out to its full extension. Next, lift the drawer  
vertically to dis-engage the drawer slide wheel from  
the slide frame and remove the entire drawer. To re-  
place the drawer, reverse the process.

VII. o - 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 12.

A lockout can not be programmed to start at 12:00 am or 12:30 am due to conflicts 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.
