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.

CZ-18BT1U, CS-KE12NB41, CS-KE18NB4UW, CU-KE18NKU, CU-KE12NK1 specifications

The Panasonic CS-KE18NB4UW and CU-KE12NK1, along with the CS-KE12NB41, CZ-18BT1U, and CU-KE18NKU, represent a suite of advanced air conditioning solutions built with cutting-edge technologies designed to provide optimal comfort, energy efficiency, and air quality in various settings.

One of the standout features of this lineup is the inverter technology. Inverter air conditioners adjust the compressor speed to maintain the desired temperature efficiently. This leads to significant energy savings compared to traditional air conditioners, which tend to frequently cycle on and off, consuming more power. By continuously regulating the temperature, the Panasonic units not only save electricity but also prolong the lifespan of the compressor.

Another noteworthy characteristic is the nanoe™ technology integrated into some of these models. Nanoe™ technology uses hydroxyl radicals to purify the air, minimizing harmful bacteria and allergens. This makes the Panasonic units particularly suitable for users with allergies or respiratory issues, providing a cleaner and healthier indoor environment.

In terms of design, these models are sleek and compact, allowing them to fit seamlessly into any room decor, whether in a home, office, or commercial space. The quiet operation is another advantage, making them ideal for bedrooms and study areas where minimal noise is essential.

Furthermore, the CS-KE18NB4UW and CU-KE12NK1 offer a range of powerful cooling and heating capacities, making them versatile solutions for various climate conditions. The cold climate performance ensures consistent heating in colder regions, while the robust cooling capabilities make them perfect for hot summer months.

The user-friendly features include a smart remote control system, allowing users to adjust settings with ease from a distance. Some models are equipped with Wi-Fi capability, enabling integration with smart home systems for enhanced control and programmability.

In conclusion, the Panasonic CS-KE18NB4UW, CU-KE12NK1, CS-KE12NB41, CZ-18BT1U, and CU-KE18NKU air conditioning units exemplify innovation and efficiency. With their inverter technology, air purification features, compact designs, and smart functionalities, they stand out as ideal choices for maintaining comfortable and healthy indoor environments throughout the year.
