III. e - CORD & PLUG:
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.
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.
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. 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.
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 12” clear-
ance overhead of the condensing unit or allow for unre-
stricted air flow at the back of the unit. Clearance of at
least 12” above is required in order to perform certain
maintenance tasks.
IV. OPERATION
IV. a - EVEN-THAW OVERVIEW:
The “Even-Thaw” refrigerator was specially designed
to thaw frozen food product under safe, temperature
controlled conditions. 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 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.

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 be-
hind 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 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.
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.
IV. d - BATCH LOADING:
The Even-Thaw model can accommmodate any size partial
load, or up to twenty eight (28) 18” x 26” pans 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.
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. 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.
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) 18” x 26” pan per pair of tray slides or (2)
14” x 18” pans per pair of tray slides, per section.
