II. RECEIPT INSPECTION  
III. INSTALLATION (contd)  
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.  
Door keys will be attached to the handle with a nylon  
strip. The handle is protected by an easily removable  
nylon netting.  
III. c - INSTALLING LEGS OR CASTERS:  
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.  
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 without first obtaining written per-  
mission (return authorization).  
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 1). 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.  
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.  
Fig. 1  
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.  
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 2). The caster bolts are tightened using a  
1/2socket wrench.  
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.  
Fig. 2  
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 - TRAY SLIDES:  
Reach-In models are supplied with fourteen (14) pairs  
of #1 type tray slides on 4centers. These are shipped  
installed from the factory, and are easily removable  
for cleaning without tools.  
6high stainless steel legs are supplied standard for  
all Traulsen reach-in Even-Thaw models. Casters in

III. INSTALLATION (contd)  
IV. OPERATION (contd)  
IV. c - EVEN THAW OPERATION:  
III. e - CORD & PLUG:  
The Traulsen Even-Thaw cabinet is a refrigerator, with two  
important additional features: 1) the ability to introduce  
small amounts of heat into the cabinet, and 2) increased  
air flow, indicated by the presence of blowers mounted be-  
hind the mullion.  
Most self-contained models are supplied with a cord &  
plug attached. It is shipped coiled at the top of the cabi-  
net, secured by a nylon strip. For your safety and pro-  
tection, all units supplied with a cord and plug include 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 under  
any circumstances, cut or remove the round grounding  
prong from the plug, or use an extension cord.  
The Even-Thaw refrigerator operates continually, the intro-  
duction of frozen product lowers the cabinet temperature  
below the heater setpoint temperature (37°F). This prompts  
the refrigeration system to turn OFF, and the heaters to turn  
ON. Anytime the cabinet air temperature is below the heater  
setpoint temperature, additional heat is added. Heater op-  
eration is controlled proportionally, i.e. the colder the cabi-  
net temperature, the longer the heaters remain in opera-  
tion. When the cabinet air temperature reaches above the  
heater setpoint temperature, the heaters turn OFF.  
III. f - POWER SUPPLY:  
The supply voltage should be checked prior to connec-  
tion to be certain that proper voltage for the cabinet wir-  
ing is available (refer to the serial tag to determine cor-  
rect unit voltage). Make connections in accordance with  
local electrical codes. Use qualified electricians.  
When the cabinet air temperature reaches the upper refrig-  
erator setpoint temperature (40°F), the refrigeration cycle  
is initiated. As long as product does not lower the cabinet  
temperature below the lower refrigeration setpoint tempera-  
ture (37°F), the cabinet will continue to cycle between 38°F  
and 40°F. Upon completion of a thaw cycle, the thawed  
product should then be removed from the Even-Thaw cabi-  
net and placed in a dedicated storage refrigerator.  
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 units serial tag).  
III. g - WIRING DIAGRAM:  
Refer to the wiring diagram for any service work per-  
formed on the unit. Should you require one, please con-  
tact Traulsen Service at (800) 825-8220, and provide the  
model and serial number of the unit involved.  
IV. d - BATCH LOADING:  
The Even-Thaw model can accommmodate any size partial  
load, or up to twenty eight (28) 18x 26pans of product.  
Use of aluminum pans is highly recommended. Product  
should be placed on pans in one layer only to allow for  
proper air flow.  
III. h - CLEARANCE:  
In order to assure optimum performance, the condens-  
ing unit of your Traulsen unit MUST have an adequate  
supply of air for cooling purposes. Therefore, the oper-  
ating location must either have a minimum of 12clear-  
ance overhead of the condensing unit or allow for unre-  
stricted air flow at the back of the unit. Clearance of at  
least 12above is required in order to perform certain  
maintenance tasks.  
When completely loaded with frozen product (at approxi-  
mately -5°F), the interior cabinet air temperature will begin  
to drop and approach the product temperature as a result.  
When this occurs the heaters begin operation in order to  
return the cabinet temperature back up to the heater  
setpoint temperature (37°F). This portion of the thaw cycle  
may take place for approximately 8 to 12 hours. With a full  
product load the interior cabinet temperature should re-  
main at or below 37°F for approximately 8 to 12 hours of  
the expected 18-24 hour total thaw cycle time.  
IV. OPERATION  
IV. a - EVEN-THAW OVERVIEW:  
The Even-Thawrefrigerator was specially designed  
to thaw frozen food product under safe, temperature  
controlled conditions. It is not intended as a storage  
refrigerator.  
IV. e - PROCESS LOADING:  
If the cabinet is unloaded as needed and replaced with  
frozen product, the average cabinet temperatures remain  
higher. A fully loaded cabinet with the refrigeration sys-  
tem cycling from 38°F to 40°F thaws product faster than  
one maintaining operation at below 32°F air temperatures  
for several hours.  
NOTE: USING THIS REFRIGERATOR FOR STORAGE OF  
UNCOVERED PRODUCT IS NOT RECOMMENDED.  
IV. b - EXPECTED PERFORMANCE:  
The Traulsen Even-Thaw refrigerator is designed to thaw a  
full load of frozen food product (see BATCH LOADING for  
guidelines) in approximately 18 to 24 hours. However, be  
aware that actual thawing times will vary depending upon  
a number of variables, such as product type, product pack-  
aging, density, spacing, etc. Please note that some other  
loading variables, such as product location, are not impor-  
tant to thawing and do not effect thaw cycle duration.  
IV. f - INTERIOR ARRANGEMENTS:  
Each reach-in Even-Thaw model includes 14 pairs of #1 tray  
slides (16 gauge stainless steel angle type) for bottom sup-  
port of either: (1) 18x 26pan per pair of tray slides or (2)  
14x 18pans per pair of tray slides, per section.

IV. OPERATION (contd)  
V. CARE & MAINTENANCE  
IV. g - ADJUSTING THE TEMPERATURE SCALE:  
The Traulsen Even-Thaw model is preset at the factory  
to operate within strict temperature parameters. Should  
these settings require adjustment, please contact our  
Service Department at (800) 825-8220.  
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 clean-  
ing 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 en-  
ergy.  
IV. h - OPERATOR CONTROLS, BLOWER SWITCH:  
As delivered from the factory, all RET models are preset  
to operate as described in section IV B. However, if  
needed the unit can also be set to operate as a high ca-  
pacity refrigerator.  
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 3). Once  
the screws are removed, the panel can be pivoted up-  
wards allowing full access to the front facing condenser  
(see figure 4). 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.  
To accomplish this a Blower Switch is located behind the  
cabinet louvers towards the center. It is labeled ON/OFF.  
As delivered, this is in the ON position, allowingthe unit  
to operate in the even-thaw mode. When in the OFF posi-  
tion, this disables two internal mullion blowers, allowing  
the unit to operate as a high capacity refrigerator.  
Return the Blower Switch to the ON position prior to at-  
tempting another even-thaw batch. Failure to do so will  
result in increased thaw times.  
IV. i - CALL SERVICE LIGHT:  
Lower louver assembly and replace the screws to hold  
it in place.  
This red light is located above the front panel thermom-  
eter. If illuminated, it may indicate a failure or problem with  
one of the temperature sensing probes inside the Even-  
Thaw unit. If one of the temperature sensing probes fail,  
the unit will default to a preset refrigeration cycle in an at-  
tempt to maintain safe product temperatures. The refrig-  
eration system and fans will continue to function.  
Fig. 3  
If the light is illuminated, the unit WILL NOT function in the  
thaw mode until the faulty component is repaired. If illumi-  
nated, contact your authorized service agent.  
Fig. 4  
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 screwswhich secure the  
hinge in place on the door. To remove the cabinet por-  
tion 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:  
VI. a - SERVICE INFORMATION:  
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 it-  
self must be at room temperature. Insert the four cor-  
ners 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 com-  
pletely seated in place (see figure 5 for proper gasket  
placement).  
Before calling for service, please check the following:  
Is the electrical cord plugged in?  
Is the fuse OK or circuit breaker on?  
Is the power switch ON?  
If after checking the above items and the unit is still  
not operating properly, please contact an authorized  
Traulsen service agent. A complete list of authorized  
service agents was provided along with your Traulsen  
unit. If you cannot locate this, you may also obtain  
the name of a service agent from the Tech Service page

V. d - CLEANING THE EXTERIOR:  
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.  
VI. c - WARRANTY REGISTRATION:  
For your convenience, the warranties on your new  
Traulsen unit may be registered with us by one of two  
methods. Completing the enclosed warranty card  
(shipped with the unit), or by filling out the on-line  
warranty registration form located on the Technical  
Service page of our website (www.traulsen.com).  
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.

VII. GENERAL USE, OPERATION & SERVICE SUMMARY  
VI. b - LOADING GUIDELINES:  
VI. a - INTRODUCTION/OVERVIEW:  
The Even-Thaw model can accommodate any size  
partial load, or up to (28) 18x 26pans of product (for  
example approximately 672 lbs. of chicken). Use of alu-  
minum pans is highly recommended. Product should be  
placed on pans in one layer only to allow for proper air-  
flow. With a full load thaw time will be between 22 & 24  
hours. Overloading and/or double wrapping product will  
extend thaw times.  
The Traulsen Even Thaw is designed to be used as a  
thawing cabinet. While it may be utilized in a  
refrigeration mode, that is not its intended use. Its  
function is to hold the cabinet temperature in the  
range from 38 to 40 degrees to thaw product within  
the food-safe temperature zone. It has not been  
configured to hold colder product temperatures in the  
35 to 38 deg F range as desired by some customers.  
Frozen product placed into the unit will pull the  
cabinet temperature below the heater set point (37  
deg.) and the unit will begin to function in the thaw  
mode. This prompts the refrigeration system to turn  
OFF, and the heaters to turn ON. The fans remain ON,  
circulating this cold air around the product, allowing  
for rapid thawing. When cabinet air temperature  
reaches the upper set point (38 deg. although the  
product is actually much colder), the heaters turn OFF.  
VI. c - LED LIGHTS:  
The controller has two LED lights that can be useful. One  
is marked H, which will be lit when in the Refrigeration  
mode. The other is marked G and will be lit during the  
Thaw mode. When the H LED is lit the controller will  
supply line voltage to the compressor relay coil closing  
the N/O contacts in turn supplying line voltage to the  
condensing unit. When the G LED is lit the controller  
will supply between 3 to 30 VDC to the solid-state relay  
coil closing the N/O contacts in turn supplying line  
voltage to the mullion heater.  
As the cabinet temperature reaches the heater set  
point, the heat will be cycled off while the internally  
generated heat from the circulation fans continues to  
add heat to the cabinet. If sufficient cold capacity or  
possibly other frozen product is added to the unit and  
subsequently lowers the cabinet temperature more  
than 1 degree below the heater set point, the heat will  
again turn on to thaw the product.  
VI. d - CALL SERVICE LIGHT:  
If lit, this indicates that one of the two temperature  
sensors is either OPEN or SHORTED. To check the  
resistance value per given temperature is correct place  
the sensor in an ice bath (32 deg.). The resistance value  
should be 100 ohms + 2%. There is a cabinet sensor  
inside the heater/blower chamber and another sensor in  
the evaporator coil.  
If the cold capacity of the product no longer sufficiently  
pulls down the cabinet temperature below the heater  
set point, the cabinet temperature will slowly rise to  
attain the evaporator coil cut-in set point (41 deg.) and  
energize the refrigeration system. The unit will remain  
in the refrigeration mode until the cabinet  
temperature pulls down to the compressor cut-out set  
point (38 deg.). The unit will continue to operate and  
cycle in the refrigeration mode.  
The units incorporate a mode switch located behind  
the louvered panel. Switching to the Refrigeration  
mode (switch OFF) will turn off two internal blower fans  
and will reduce the Thaw mode (switch ON)  
performance. Subsequently, switching to the Thaw  
mode will have reduced refrigeration performance.  
The controller has been preset at the factory and  
should not require any adjustments. Traulsen  
engineering EXPECTS no changes be made to any set  
points or parameter settings without discussing the  
situation and obtaining approval to do so. Modifying  
the default set points could disrupt the operation/  
functional programming algorithm and result in erratic  
unit operation.

VIII. EXPECTED THAW PERFORMANCE/OPERATIONAL TROUBLESHOOTING  
VIII. a - INTRODUCTION:  
VIII. f - EQUIPMENT ISSUES:  
Even thaw performance is a function of many factors,  
especially those involving product types and loading.  
As a result, actual thaw times will vary as even similar  
sized loads of the same product will exhibit some  
differences in their thawing characteristics.  
If improper loading has been eliminated as a possible  
cause for extended thaw cycle times, there are  
several system checks which can be done to diagnose  
the Traulsen Even-Thaw unit.  
First, the amp draw should be checked early in the  
thaw cycle. Shortly after loading the unit with frozen  
product, the electronic control LED, G, should be  
illuminated as the cabinet temp will probably be in the  
30 to 34 degree F range as per the control read-out.  
At this time, full heat should be on. This is a 1300 watt  
heater, 115 vac, is about 11.3 amps. Add 4 blowers at  
1.1 amps and a few amps for the controls and the total  
amp draw should be approximately 16 to 16.5 amps.  
VIII. b - TEST PARAMETERS:  
To provide a general performance baseline, Traulsen  
performed some controlled testing in our lab which  
may provide the operator with an approximate idea on  
what to expect from their Even-Thaw unit. Full load  
batches of frozen product were used as follows:  
ONE SECTION MODELS  
When the cabinet temperature reaches 36°F, the LED  
Gwill pulse indicating the heat is now being  
applied at a 50% level. At 37°F, the LED Gwill be  
turned off indicating thaw heat is off. This cycle will  
repeat until the cabinet temperature stabilizes between  
37-41°F. When the cabinet temperature exceeds 41°F,  
the LED Hilluminates indicating that the cabinet has  
switched to refrigeration cycle. The cabinet will now  
cycle between 37-41°F in order to maintain cabinet  
temperature.  
336 lbs. of chicken, distributed between 14 tray levels.  
Each level consisted of 24 lbs. of product loaded into  
two pans (four 6 lb. pkgs. of frozen product total per  
level/two 6 lb. pkgs. per tray).  
TWO SECTION MODELS  
672 lbs. of chicken, distributed between 28 tray levels.  
Each level consisted of 24 lbs. of product loaded into  
two pans (four 6 lb. pkgs. of frozen product total per  
level/two 6 lb. pkgs. per tray).  
Also, be certain that the thaw switch has not been  
turned OFF. This is located behind the louvers and  
has a protective guard around it. This switch can turn  
OFF 2 of the 3 mullion blowers and reduce airflow  
which reduces thaw capability. In addition, the blower  
wattage actually adds heat to the unit and helps  
augment the units thawing capability.  
VIII. c - TEST RESULTS  
Under these actual load parameters, the one-section  
model generally required approximately 19-22 hours  
in order to completely thaw the entire load. The two-  
section model required approximately 24-26 hours to  
completely thaw the entire load.  
VIII. g - OTHER CAUSES OF EXTENDED THAW TIMES:  
Some frozen products are often stored in large,  
irregularly shaped packages. If used, these should  
always be located along the outside wall with the  
largest packages being placed closest to, but not  
directly against, the wall. It is IMPERATIVE that such  
large packages not be placed up against the center  
mullion air ducts. This could result in blocked airflow.  
REDUCED AIR MOVEMENT EQUATES TO LONGER  
THAWING TIMES.  
VIII. d - RESULTS AS A FUNCTION OF PRODUCT MIX:  
The above thaw times were based upon a mixed load  
of different chicken products typically found in many  
establishments. It is important to note that initially, all  
tests performed were based on a mixed load of  
product. This consisted of approximately 1/4 nuggets,  
1/4 strips, 1/4 to 1/3 breasts. This MIXED batch thawed  
in the times listed above. In actual operation, thaw  
batches consisting of a single type of product, or other  
ratios of different products may require more time for  
thawing. Both this and larger size loads can both  
contribute to longer thaw times.  
Care should also be taken to avoid pushing other pkgs.  
of frozen product up against the mullion sheet metal  
ducts. Airflow could be blocked resulting in a similar  
extended thaw time situation.  
VIII. e - INCOMPLETE THAWING:  
In operation, incomplete thawing (i.e. bags of product  
in which not every piece was completely thawed) has  
been found to usually be the result of those pkgs.  
respective pan level having had restricted airflow due  
to overloading (from stacked pkgs. or irregular shaped  
packages that blocks air from getting to the pkgs.  
closest to the cabinet interior side wall or rear).  
Allowing for proper air-flow around each pkgs. of  
frozen product should eliminate this situation from  
occurring.  
Another scenario to avoid is for packages to be placed  
inadvertently up against the outside walls. They will  
also block air flow down the sides of the unit. This is  
especially an issue with the right side wall  
because when the unit returns to normal refrigerated  
operation mode, the cold air flows from the upper right  
ceiling evaporator outlet, down the wall, and then  
mixes into the cabinet, distributed by all the mullion  
blowers. If the right wall is blocked, and especially if  
blocked near the top right of the cabinet, the cold

VIII. OPERATIONAL TROUBLESHOOTING (contd)  
VIII. g - OTHER CAUSES OF EXTENDED THAW TIMES (contd):  
evaporator exit air can be short circuited on to the top two or three upper right hand levels and be routed right back  
to the return evaporator inlet duct. Therefore, those upper shelves could get very cold and perhaps a substantial  
amount of product on the right side could become very cold and possibly even refreeze (as the  
evaporator outlet air temperature is 20 degrees F).
