About the temperature controls.

The unit will have one of the temperature controls shown below:

Internal Temperature

Controls

Internal Dial Control (0-9)

External Set Point

Controls (0-9)

The temperature controls are preset in the factory at 5 for both the refrigerator and freezer compartments.

To adjust the set point temperature, press the WARMER or COLDER button on either the Freezer or Refrigerator side. The set point light will come on. Press WARMER or COLDER until the desired setting is reached.

Several adjustments may be required. Each time you adjust controls, allow 24 hours after each adjustment for the refrigerator to reach the setting you have selected.

Setting either or both controls to 0 stops cooling in both the freezer and refrigerator compartments, but does not shut off electrical power to the refrigerator.

Control settings will vary based on personal preferences, usage and operating conditions and may require more than one adjustment.

NOTE: The refrigerator is shipped with protective film covering the temperature controls. If this film was not removed during installation, remove it now.

21, 23, 25, 27, 29 specifications

The GE 21, 23, 25, 27, and 29 series of locomotives represent a significant evolution in diesel-electric technology, showcasing General Electric's commitment to innovation and performance in the rail industry. These models, produced from the late 20th century to the early 21st century, are designed to meet a variety of operational needs.

The GE 21, introduced in the early 1990s, was notable for its efficiency and reliability. It utilized a 12-cylinder engine coupled with GE's innovative software systems, allowing for enhanced fuel economy and lower emissions. The locomotive's modular design enabled easy maintenance, which was a significant advantage for rail operators looking to minimize downtime.

Moving to the GE 23, this model offered increased power and improved traction systems, reflecting the industry's demand for stronger and faster trains. With an upgraded traction control system, the GE 23 provided better performance on challenging grades and under various load conditions. Its spacious cab and ergonomic controls also emphasized operator comfort and productivity.

The GE 25 built upon the successes of its predecessors, featuring advanced microprocessor controls and a more robust engine. This model was designed with higher horsepower, making it suitable for heavy freight operations. The GE 25’s aerodynamic design reduced drag, enhancing fuel efficiency during long hauls. Additionally, the locomotive included state-of-the-art diagnostic systems, allowing for real-time monitoring of performance metrics.

In the evolution of these series, the GE 27 introduced even more technological advancements, including improved lightweight materials and enhanced safety features. This model could accommodate various cargo types and was compatible with modern signaling systems, making it versatile for different rail networks. The GE 27 was designed with sustainability in mind, further reducing emissions and adhering to stricter environmental regulations.

Finally, the GE 29 series marked a major leap forward with the integration of cutting-edge digital technology. These locomotives featured predictive maintenance capabilities, allowing operators to foresee potential mechanical issues before they resulted in failures. The GE 29 series also placed a strong emphasis on energy efficiency, incorporating regenerative braking systems that harness energy during braking for reuse.

Overall, the GE 21, 23, 25, 27, and 29 locomotives reflect General Electric’s ability to innovate continually, combining power, efficiency, and advanced technology to meet the changing demands of the rail industry. Each model brought unique features and improvements, ultimately enhancing the performance and reliability of rail freight services.
