Carrier Air-cooled 7 kW, 12 kW and 15 kW Generators

6.When frequency is correct at no load, check the AC voltage reading. If voltage is incorrect, the voltage regulator may require adjustment.

7.Restart the unit.

8.Slowly turn the idle adjust screw to adjust the no-load idle frequency to 63-63.5 Hz (with top open).

9.The governor is now set.

1.Loosen governor clamp bolt (See Figure 1.6).

2.Completely remove the idle spring.

3.With governor arm at wide open throttle position (rotated fully clockwise), rotate governor shaft fully clockwise. Tighten clamp bolt to 84 inch-pounds.

4.Start unit and apply full load. Use full load speed adjust screw (Figure 1.7) to adjust frequency to 58 Hz.

5.Remove load, stop engine, loosen the idle adjust screw and reconnect the idle spring.

6.Push the governor arm to the closed throttle position. Make sure the idle spring does not stretch at all.

ADJUSTMENT

With the frequency between 62-63 Hertz, slowly turn the slotted potentiometer (Figure 1.8) until line voltage reads 247-252 volts.

NOTE:

The access panel on top of the control panel must be removed to adjust the voltage regulator.

NOTE:

The voltage regulator is housed above the generator's control panel. The regulator maintains a voltage in direct proportion to frequency at a 2-to-1 ratio. For example, at 62 Hertz, line-to-neutral voltage will be 124 volts.

VALVE CLEARANCE

After the first 6 months of operation, adjust the valve clearance in the engine.

Important: If feeling uncomfortable about doing this procedure or the proper tools are not available, please contact a Carrier dealer for service assistance. This step necessary to insure the longest life for the engine.

To adjust valve clearance:

Make sure the engine is at room temperature.

Make sure that the spark plug wire is removed from the spark plug and out of the way.

ASPAS1CCA012, ASPAS1CCA015 specifications

The Carrier ASPAS1CCA015 and ASPAS1CCA012 are advanced air conditioning units designed to offer superior climate control in residential and light commercial settings. Both models reflect Carrier's commitment to innovation, energy efficiency, and user comfort.

One of the primary features of these units is their inverter technology. This smart technology adjusts the compressor speed in real-time, allowing the system to operate efficiently and maintain a consistent temperature. This results in reduced energy consumption and lower utility bills while providing a more comfortable indoor environment.

The ASPAS1CCA015 and ASPAS1CCA012 also include a state-of-the-art air filtration system. These units are equipped with a high-efficiency particulate air (HEPA) filter that effectively captures dust, allergens, and pollutants. This feature contributes to improved indoor air quality, making them ideal for allergy sufferers and those concerned about indoor air pollution.

In terms of performance, both models deliver impressive cooling and heating capacities. The ASPAS1CCA015 has a cooling capacity of 15,000 BTUs, while the ASPAS1CCA012 offers a cooling capacity of 12,000 BTUs. This range makes them suitable for various room sizes, ensuring effective temperature management whether during scorching summers or chilly winters.

A user-friendly digital thermostat and Wi-Fi connectivity are additional features that enhance the usability of these models. Homeowners can control their air conditioning systems remotely via smartphones or tablets, enabling them to adjust settings for optimum comfort and efficiency even when they are not at home.

The units are designed with quiet operation in mind. They utilize advanced silencing technologies, ensuring that noise levels remain low, allowing for peaceful environments during night-time or in quiet settings. This is particularly beneficial for bedrooms, nurseries, or offices where distraction-free air conditioning is essential.

Moreover, both models are compliant with the latest standards for energy efficiency, earning high SEER (Seasonal Energy Efficiency Ratio) ratings. This not only promotes environmental sustainability but also aligns with governmental incentives aimed at reducing energy consumption.

In summary, the Carrier ASPAS1CCA015 and ASPAS1CCA012 are equipped with cutting-edge technologies and features that make them reliable and efficient air conditioning solutions. With their inverter technology, advanced filtration systems, remote connectivity, and quiet operation, these units represent a combination of comfort, convenience, and environmental responsibility that meets the needs of modern users.
