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
&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
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)
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
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
