III. INSTALLATION (continued)

III.d - INSTALLING LEGS OR CASTERS (cont’d): 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 3). The caster bolts are tightened using a 1/2” socket wrench.

III.e - SHELF PINS:

The unit ships with shelves and shelf pins installed. Check all shelf pins to assure they are tightened down as they may have come loose during shipping. Ro- tate the pins clockwise until they are secured against the side of the cabinet.

III.f - CORD & PLUG:

Most self-contained models are supplied with a cord

&plug attached. It is shipped coiled at the rear of the cabinet, secured by a nylon strip. For your safety and protection, all units supplied with a cord and plug in- clude 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 un- der any circumstances, cut or remove the round grounding prong from the plug, or use an extension cord.

III.g - POWER SUPPLY:

The supply voltage should be checked prior to con- nection to be certain that proper voltage for the cabi- net wiring is available (refer to the serial tag to deter- mine correct unit voltage). Make connections in ac- cordance 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.h - WIRING DIAGRAM:

Refer to the wiring diagram for any service work per- formed on the unit. Should you require one, please contact Traulsen Service at (800) 825-8220, and pro- vide the model and serial number of the unit involved.

III.i - PLACING EQUIPMENT ON TOP OF UNIT: Equipment may be placed on top of your Traulsen full- size undercounter or equipment stand. However, please be aware that a stainless steel worktop is re- quired on cabinets being used to support equipment weighing in excess of 100 lbs. or producing heat in excess of 140°F to the top surface. Optional stainless steel tops are available from Traulsen.

IV. OPERATION

IV. a - REFRIGERATORS:

Both refrigerators and freezers do not require manual defrosting. During normal operation, a refrigerator continuously circulates above freezing cabinet air through the coil. A compressor “OFF” cycle occurs every hour to melt any frost which may accumulate on the coil during the compressor “ON” cycle. The control will read “dEF” when this occurs (see figure 4). With standard holding refrigerators, high relative humidity is also maintained to prevent dehydration of stored product.

IV. b - FREEZERS:

During normal operation, a freezer continuously cir- culates below freezing cabinet air through the coil. The coil requires a periodic defrosting for proper opera- tion. This is accomplished by an automatic, time acti- vated, temperature/time terminated, defrost program, utilizing hot gas from the refrigeration system. The controller is preset at the factory for six equally spaced defrost cycles within each 24-hour period.

At the start of a freezer defrost cycle, both the com- pressor and evaporator fans are OFF. The INTELA- TRAUL control will read “dEF” (see figure 4). When a temperature device affixed to the coil senses 70°F, the coil is fully defrosted and the compressor operation is resumed. The coil fans are delayed from starting at the termination of a defrost cycle. Fan operation is automatically resumed, they can also be started by a time or temp delay (whichever comes first). In case of temp delay, it uses the same coil sensor and starts at 32°F. The total refrigeration system operation is then resumed.

During freezer defrost operation, heat is confined to the coil enclosure to prevent any significant rise in temperature within the food zone. The fan delay con

UL Series, UC Series specifications

The Traulsen UC Series and UL Series refrigeration units are designed for commercial kitchens that require reliable and efficient food storage solutions. Known for their durability and advanced technology, these units serve a critical role in maintaining the quality and safety of perishable items.

The UC Series offers both upright and undercounter configurations, making them versatile for various kitchen layouts. With robust stainless steel construction and an attractive finish, these units not only provide lasting durability but also an easy-to-clean surface. Inside, the full-width shelves offer ample storage space and adjustable options to accommodate different food items.

One of the standout features of the UC Series is its advanced digital temperature control system. This dual-sensing mechanism ensures accurate temperature readings, allowing food service operators to manage proper storage conditions efficiently. The electronic control system also includes an automatic defrost function, minimizing the need for manual intervention and reducing energy consumption.

The UL Series takes efficiency a step further with its environmentally friendly design. Equipped with a high-performance refrigeration system, the UL Series uses R-290 hydrocarbon refrigerant, which has a lower environmental impact compared to traditional refrigerants. This commitment to sustainability is further highlighted by the Energy Star certification, ensuring that the units meet strict energy efficiency guidelines.

Additional characteristics of the UL Series include a self-closing door mechanism that enhances energy conservation by minimizing airflow when the door is opened. The series also features heavy-duty casters, allowing for easy movement and cleaning around the kitchen.

Both the UC and UL series prioritize user convenience with features such as easy-to-read digital displays, integrated handles, and adjustable legs for leveling the units on uneven surfaces. These thoughtful designs contribute to a seamless workflow in busy kitchen environments, ultimately enhancing productivity.

In summary, the Traulsen UC Series and UL Series offer a blend of durability, efficiency, and cutting-edge technology, making them ideal solutions for commercial kitchens.
