Installation Instructions

ROLLERS

The rollers have 3 purposes:

Rollers adjust so the door closes easily when opened about halfway. [Raise the front about 5/8″ (16 mm) from the floor.]

Rollers adjust so the refrigerator is firmly positioned on the floor and does not wobble.

Rollers allow you to move the refrigerator away from the wall for cleaning.

Final leveling adjustments should be made after the refrigerator has been installed.

To adjust the rollers on 25, 27and 29models:

Turn the roller adjusting screws clockwise to raise

the refrigerator, counterclockwise to lower it. Use a 3/8″ hex socket or wrench,

or an adjustable

wrench.

To adjust the rollers on 21and 23models:

Remove the base grille by opening the doors, removing the screws at each end, and pulling it straight out.

Turn the front roller adjusting screws clockwise to raise the refrigerator, counterclockwise to lower it. Use a 3/8″ hex socket or wrench, or an adjustable

wrench.

These models also have rear adjustable rollers so you can align the refrigerator with your kitchen cabinets. Use a long-handled 5/16″ socket wrench to turn the screws for the rear rollers–clockwise to raise the refrigerator, counterclockwise to lower it.

Replace the base grille.

DOOR ALIGNMENT

After leveling, make sure that the refrigerator door is 1/16″ higher than the freezer door.

To align the doors, adjust the refrigerator door.

Using a 7/16″ socket wrench, turn the door adjusting screw to the right to raise the door, to the left to lower it. (A nylon plug, imbedded in the threads of the pin, prevents the pin from turning unless a wrench is used.)

After one or two turns of the wrench, open and close the refrigerator door and check the alignment at the top of the doors.

Refrigerator door needs to be raised.

To remove the base grille,

7/16Socket Wrench

open the doors, remove

 

the screw at each end of

 

the base grille and then

 

pull the grille straight out.

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.
