10-7. Charging Additional Refrigerant

10-7-1. When Tubes are Extended

Observe the proper amount of refrigerant as stated in this service manual or the installation manual that came

with the indoor unit. Charge additional refrigerant in liquid state only.

CAUTION

Never charge additional refrigerant if refrigerant is leaking from the unit. Follow instructions given in "10-6. In Case Refrigerant is Leaking" and completely carry out repairs. Only then should you recharge the refrigerant.

10-8. Retro-Fitting Existing Systems

10-8-1. Use of Existing Units

Never use new refrigerant R410A for existing units which use R22. This will cause the air conditioner to

operate improperly and may result in a hazardous condition.

10-8-2. Use of Existing Tubing

If replacing an older unit that used refrigerant R22 with a R410A unit, do not use its existing tubing. Instead, completely new tubing must be used.

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.
