Indoor fan stops occasionally during automatic fan speed setting.

Operation is delayed a few minutes after restart.

Outdoor unit emits water/steam.

Timer indicator is always on.

Power indicator blinks before the unit is switched on.

Cracking sound during operation.

►• Condensation effect due to cooling process.

►• Refrigerant ﬂow inside the unit.

►• This may be due to damp smell emitted by the wall, carpet, furniture or clothing.

►• This helps to remove the surrounding odours.

►• The delay is a protection to the unit’s compressor.

►• Condensation or evaporation occurs on pipes.

►• The timer setting repeats daily once set.

►• This is a preliminary step in preparation for the operation when the ON timer has been set.

►• Changes of temperature cause the expansion/contraction of the unit.

Check the following before calling for servicing.

The Panasonic CS-S12JKUW, CU-S18JKU, CU-S22JKU, CU-S9JKU, and CSS-22JKU are a series of advanced air conditioning systems designed to provide effective cooling, heating, and air purification. These units are perfect for residential and commercial applications, delivering comfort along with energy efficiency.

One of the standout features of these models is their capacity for inverter technology. This technology enables the air conditioners to adapt their cooling and heating output based on the current temperature, resulting in significant energy savings. The inverter system operates quietly and offers a more stable indoor climate by reducing temperature fluctuations.

Another notable characteristic is the Econavi technology present in these models. Econavi utilizes intelligent sensors to detect human activity and sunlight, optimizing the cooling performance based on real-time conditions. This ensures that energy is not wasted in unoccupied rooms while maintaining comfort for occupants.

The CS-S12JKUW, for instance, boasts a sleek design that complements modern interiors. It operates efficiently with a high Energy Efficiency Ratio (EER) that upholds environmental standards while reducing energy costs. The unit also includes a powerful air purification system that filters out dust and allergens, ensuring the air quality remains high.

For larger spaces, the CU-S18JKU is a robust choice, providing a higher cooling capacity without compromising on energy efficiency. Similarly, the CU-S22JKU is designed for larger areas, featuring an enhanced compressor that supports quicker and more effective cooling during peak temperatures.

The CU-S9JKU, aimed at smaller spaces, maintains all the efficiency features of its larger counterparts while being compact and easy to install. Its quiet operation makes it suitable for bedrooms and study areas where noise levels can be a concern.

Additionally, the CSS-22JKU combines powerful performance with advanced control options, including remote control and app compatibility for convenient operational management.

In summary, the Panasonic CS-S12JKUW, CU-S18JKU, CU-S22JKU, CU-S9JKU, and CSS-22JKU air conditioning units exemplify innovation and efficiency, ensuring a comfortable environment through advanced technologies that prioritize user experience and energy conservation.
