Defrost detection and release

Reverse-Cycle Defrosting

Defrosting Sequence

Heating operation

Outdoor fan ON 4-way valve ON

Frost sensing

Defrost detection occurs in either of the following cases:

•The temperature of the heat exchanger remains at or below the L1 line for 3 minutes after the start of HEAT operation.

•The temperature of the heat exchanger remains at or below the L2 line for 120 minutes after the start of HEAT operation.

Outdoor heat

exchanger temp.

Ambient temp.

Frosting area

Reverse-cycle defrosting operation

Compressor 1 minute after it is stopped, compressor is ON.

Outdoor fan OFF

Indoor fan OFF

4-way valve OFF

Operation lamp Repeatedly switches between red and orange illumination.

Releasing of defrosting

Outdoor heating exchanger temp. is over 57.2°F (14°C).

Defrosting operation lasts 12 minutes (maximum). 2 minutes after it is stopped, compressor is ON.

4-way valve is ON. Outdoor fan is ON.

NOTE

If the air conditioner is turned off during the defrosting cycle, it will continue defrosting and turn itself off after defrosting is completed.

CT (Peak current cut-off control)

•This function prevents the circuit breaker or fuse from operating to open the circuit. This function works when electrical current

has increased due to an increase in the cooling / heating load, or to a decrease in the power supply voltage. In these cases, operation frequency is reduced or operation is interrupted auto- matically to control the electrical current for operation.

•When the cause of the increase in electrical current is rectified, the system will resume operation in the original mode.

The models boast impressive SEER (Seasonal Energy Efficiency Ratio) ratings, making them environmentally friendly options.

Panasonic's nanoe-G technology is another remarkable feature incorporated into these models. This technology helps to purify the air by generating hydroxyl radicals, which eliminate airborne particles, odors, and harmful bacteria. This results in a healthier indoor environment, conducive to both comfort and well-being. The air purification aspect not only enhances the air quality but also extends the lifespan of the HVAC system by reducing the buildup of dust and contaminants.

In terms of user convenience, both the CU-KE and CS-KE series are equipped with programmable timers, allowing users to set their desired operation schedules. They also come with a remote control for ease of use, enabling adjustments from a distance. The installation process is straightforward, and the sleek design blends seamlessly with various interior aesthetics, making them a suitable choice for any room.

Durability is a key characteristic of Panasonic air conditioning units, and the CU-KE36NKU, CS-KE36NKU, CU-KE30NKU, and CS-KE30NKU are designed to withstand varying environmental conditions. Their robust construction ensures reliability and performance over the years. Additionally, both models come with a quiet operation feature that minimizes noise levels, allowing for comfortable use without disturbing daily activities.

In summary, the Panasonic CU-KE36NKU, CS-KE36NKU, CU-KE30NKU, and CS-KE30NKU are exceptional air conditioning units that combine energy efficiency, innovative purification technology, user-friendly features, and robust durability. These models are an ideal investment for anyone seeking a reliable and high-performance cooling solution.
