Operating Instructions

Temp Control

The temp control is used to maintain the room temperature. The compressor will cycle on and off to keep the room at the same comfort level. When you turn the knob to COOLER (blue), the indoor air will become cooler. Turn the knob to WARMER (red) and the indoor air will become warmer.

3800 Series only

When the outdoor temperature is lower than 20°F, heat is provided by the electric heater in the air conditioner instead of by the heat pump.

Mode Control

HIGH COOL and LOW COOL provide cooling with different fan speeds.

HIGH HEAT and LOW HEAT provide heating with different fan speeds.

LOW FAN or HIGH FAN provides air circulation and filtering without cooling or heating.

NOTE: If you move the switch from a cool or heat setting to STOP or to a fan setting, the unit has an automatic 3-minute delay before allowing the compressor to restart in the cool or heat mode.

Care and Cleaning

About Your Heat Pump (3800 Series only)

Heat pumps can save money by removing heat from the outside air—even when the outside temperature is below freezing—and releasing that heat indoors.

To get the best performance from your heat pump, don’t change the room thermostat very often. Raising the heat setting 2–3 degrees will cause the Zoneline to use its electric heating elements in order to reach the new temperature setting quickly.

There is a three minute minimum compressor run time at any setting to prevent short cycling.

The indoor fan motor starts before the compressor and stops after the compressor cycles off.

The electric heating elements use much more electricity than heat pumps and cost more to operate.

3800 specifications

The GE 3800 is a sophisticated locomotive developed by General Electric, notable for its advanced technological features and robust design. As a member of the GE Dash 8 series, it was primarily built to cater to freight transport needs, delivering reliability and performance across various terrains.

One of the most noteworthy features of the GE 3800 is its powerful GE FDL-16 engine. This V16 four-stroke engine is known for its efficiency and durability, producing a significant amount of horsepower while maintaining low emissions. The engine's design allows for easy maintenance, which is essential for minimizing downtime in freight operations. With the capability of generating up to 3,800 horsepower, the GE 3800 can handle heavy loads while providing excellent tractive effort, making it ideal for freight-hauling.

Another critical technology integrated into the GE 3800 is its advanced electronic control system. The locomotive is equipped with a Digital Electronic Control (DEC) system that monitors and optimizes various functions, such as engine performance, braking, and traction control. This system enhances the locomotive's responsiveness, ensuring better handling of freight trains, especially in varied weather conditions.

The GE 3800 also features a robust braking system that includes dynamic and air brakes. The dynamic braking system allows for energy conservation, converting kinetic energy into electrical energy during deceleration, which can be reused when accelerating or transferred to the grid. This feature not only enhances safety but also contributes to lower operational costs.

In terms of design, the GE 3800 boasts a sturdy chassis that allows it to withstand the rigors of heavy-duty freight transport. Its aerodynamic profile reduces drag, improving fuel efficiency during operations. The locomotive is equipped with advanced wheel and axle assemblies that enhance stability and reduce wear and tear, prolonging the lifespan of the train’s components.

Safety is a primary concern in locomotive design, and the GE 3800 includes numerous safety features such as redundant systems, crash-worthy designs, and advanced signaling and communication technologies. These elements ensure that the locomotive can operate safely in busy rail networks.

Overall, the GE 3800 is a blend of power, efficiency, and modern technology, making it a preferred choice for freight operators around the world. Its combination of a powerful engine, advanced electronic control systems, robust construction, and safety features ensures that it remains a significant player in the rail transport industry.
