III. d - TRAY SLIDES:
Reach-In models are supplied with fourteen (14) pairs of #1 
type tray slides on 4” centers. These are shipped installed 
from the factory, and are easily removable for cleaning 
without tools. 
III. e - 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 aspecial three-prong 
grounding plug on the service cord. Select only a dedicated 
electrical outlet with grounding plug for power source. 
NOTE: Do not underany circumstances, cut or remove 
the round grounding prong from the plug, or use an 
extension cord.
III. f - POWER SUPPLY:
The supply voltage should be checked prior to connection to 
be certain that proper voltage for the cabinet wiring is avail-
able (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).
III. g - 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. h - 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. INSTALLATION (continued)
IV. a - EVEN-THAW OVERVIEW:
The “Even-Thaw” refrigerator was specially designed to thaw 
frozen food product under safe, temperature controlled condi-
tions. It is not intended as a storage refrigerator.
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 packag-
ing, density, spacing, etc. Please note that some other load-
ing variables, such as product location, are not important to 
thawing and do not effect thaw cycle duration.
IV. c - EVEN THAW OPERATION:
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 behind the 
mullion.
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 cabinet 
temperature, the longer the heaters remain in operation. 
When the cabinet air temperature reaches above the heater 
setpoint temperature, the heaters turn OFF. 
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 tem-
perature below the lower refrigeration setpoint temperature 
(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 cabinet and 
placed in a dedicated storage refrigerator.
