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. 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.
