III. INSTALLATION (continued)
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.
IV. OPERATION
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.
