11-3. Tools Specifically for R410A

For servicing, use the following tools for R410A

Tool Distinction

Tool Name

 

 

 

Gauge manifold

 

Charging hose

 

Gas leak detector

 

Refrigerant cylinder

 

Charging cylinder

 

Refrigerant recovery unit

Tools specifically for R410A

Vacuum pump with anti-reverse flow (*1)

 

(Solenoid valve-installed type, which prevents oil from flowing back into the

 

unit when the power is off, is recommended.)

 

Vacuum pump (*2)...can be used if the following adapter is attached.

 

Vacuum pump adapter (reverse-flow prevention adapter) (*3).

 

(Solenoid valve-installed adapter attached to a conventional vacuum pump.)

 

Electronic scale for charging refrigerant

 

Flare tool

 

 

 

Bender

Tools which can be com-

Torque wrench

 

monly used for R22,

Cutter, reamer

R407C, and R410A

Welding tool, nitrogen gas cylinder

 

 

 

CAUTION

The above tools specifically for R410A must not be used for R22 and R407C. Doing so will cause malfunction of the unit.

For the above vacuum pump (*1, *2) and vacuum pump adapter (*3), those for R22-type units can be used for R410A-type. However, they must be used exclusively for R410A and never alternately with R22 and R407C.

To prevent other refrigerants (R22, R407C) from being mistakenly charged to this unit, shape and external diameter of the service port screw has been altered.

<External diameter of service port> R410A : 5/16" R22, R407C : 1/4"

11-4. Tubing Installation Procedures

When the tubes are connected, always apply HAB oil on the flare portions to improve the sealing of tubing. The following is the HAB oil generally used:

Esso: ZERICE S32

NOTE For details on tubing installation procedures, refer to the installation manuals attached to the indoor unit and outdoor unit.

Panasonic CU-KS18NKUA, CU-KS12NK1A, CS-KS12NB41 & CZ-18BT1U Tools Specifically for R410A, Tubing Installation Procedures

CS-KS18B4UW & CZ-18BT1U, CS-KS12NB41 & CZ-18BT1U, CU-KS12NK1A, CU-KS18NKUA specifications

Panasonic has long been a reputable name in the HVAC (Heating, Ventilation, and Air Conditioning) industry, continuously innovating to provide efficient and sustainable solutions. Among their latest offerings, the CU-KS18NKUA, CS-KS18B4UW, CU-KS12NK1A, and CS-KS12NB41 split systems stand out for their advanced features and technologies designed to enhance user comfort while minimizing environmental impact.

The CU-KS18NKUA and CS-KS18B4UW units are high-capacity air conditioning systems that cater to larger spaces. One of their defining features is the inverter technology, which allows the compressor to adjust its speed according to the demand, leading to significant energy savings. The units operate quietly, contributing to a peaceful environment whether in homes or offices. Furthermore, the super-efficient energy consumption aligns with modern sustainability practices, reducing users' carbon footprints.

The advanced R32 refrigerant used in these systems is another highlight. R32 is known for its lower global warming potential compared to traditional refrigerants, making it an eco-friendly choice. These models are equipped with a powerful cooling capability while maintaining a compact and sleek design, seamlessly integrating into various interior styles.

In terms of indoor air quality, both models incorporate a multi-stage filtration system. This system effectively filters out dust, allergens, and harmful particles, ensuring cleaner indoor air. Additionally, the nanoe-G technology helps in deodorizing and purifying the air, enhancing the overall comfort and health of the environment.

The CU-KS12NK1A and CS-KS12NB41 models cater to smaller rooms but do not compromise on performance. They share similar inverter technology and energy-efficient characteristics as their larger counterparts, ensuring that users can enjoy a comfortable climate in a smaller footprint.

With an emphasis on user-friendly design, all these models come with intuitive remote controls, allowing for easy temperature adjustments and scheduling. Some units even offer Wi-Fi connectivity for remote access and monitoring via smartphone apps.

The CZ-18BT1U, often paired with these outdoor units, serves as an innovative air conditioning solution that supports energy efficiency and provides reliable cooling performance.

Overall, the Panasonic CU-KS and CS series units are ideal for consumers looking for modern, efficient, and environmentally friendly air conditioning solutions. Their combination of advanced technologies, user-centric design, and eco-conscious operation set them apart in the competitive HVAC market.
