III.f - 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.g - 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.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 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. Clear- ance of at least 12” above is required in order to per- form certain maintenance tasks.

IV. b - FREEZER NORMAL OPERATION:
During normal operation, a freezer continuously circulates below freezing cabinet air through the coil. The coil requires a periodic defrosting for proper operation. This is accom- plished by an automatic, time activated, temperature/time terminated, defrost program. The controller is preset at the
IV. b - FREEZER NORMAL OPERATION (continued): factory for six equally spaced defrost cycles within each 24- hour period.
At the start of a freezer defrost cycle, both the compressor and evaporator fans are OFF. The microprocessor control will read “dEF” (see figure 3). The electric heater (attached to the coil) is energized. When a temperature device affixed to the coil senses 70°F (models with electric defrost), the coil is fully defrosted and the compressor operation is re- sumed, defrost heaters are automatically turned off. The coil fans are delayed from starting at the termination of a defrost cycle. Fan operation is automatically resumed, or 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 op- eration is then resumed.

The Microprocessor control is set from the factory to termi- nate defrost at 20 minutes in the event of a sensor failure. This setting should never be tampered with, without first consulting the factory.
