3-9. Wiring Instructions for Inter-unit Connections

(1)Remove the 1 screw from the terminal cover, then open the cover. Be careful that the cover does not fall.

(2)Remove the 3 screws from the power box cover, then open the cover. Be careful that the cover does not fall.

(3)Use the screw to securely fasten the ground wire from the outdoor unit in place.

(4)Remove the transparent plastic cover from the 3P terminal plate.

(5)While viewing the wiring diagram, connect the inter-unit and power supply line to terminals 1, 2 and 3 on the 3P terminal plate.

(6)Remount the transparent plastic cover onto the 3P terminal plate.

(7)Be sure to use the clamping strap to fasten the wires in place.

(8)Tighten the screws to remount the terminal and the power box cover.

WARNING

Loose wiring may cause the ter- minal to overheat or result in unit malfunction. A fire hazard may also exist. Therefore, be sure all wiring is tightly connected.

When connecting each power wire to the corresponding terminal, fol- low the instructions “How to connect wiring to the terminal” and fasten the wire securely tight with the fixing screw of the terminal plate.

How to connect wiring to the terminal

a) For Indoor Unit

(1)Cut the wire end with a cutting pliers, then strip the insulation to expose the wire about 9/32" (7 mm). See the label (Fig. 9) near the terminal plate.

(2)Using a screwdriver, loosen the terminal screw on the terminal plate.

(3)Insert the wire and tighten the terminal screw completely using a screwdriver.

b) For Outdoor Unit

For solid core wiring (or F-cable)

(1)Cut the wire end with a cutting pliers, then strip the insulation to expose the solid wire about 15/16" (25 mm). (Fig. 10)

(2)Using a screwdriver, remove the terminal screw(s) on the terminal plate.

(3)Using the pliers, bend the solid wire to form a loop suitable for the terminal screw.

(4)Shape the loop wire properly, place it on the terminal plate and fix it securely with the removed terminal screw using a screwdriver.

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.
