3-6-5. Checking After Installation

Check that there are no gaps between the unit and the ceiling panel, or between the ceiling panel and the ceiling sur- face. Gaps may cause water leakage and condensation.

Check that the wiring is securely connected.

If it is not securely connected, the auto flap will not operate. In addition, water leakage and condensation may occur.

3-6-6. When Removing the Ceiling Panel for Servicing

When removing the ceiling panel for servicing, remove the air-intake grille and air filter, disconnect the flap and the indi- cator wiring connectors inside the control box, and then remove the 4 mounting screws.

3-6-7. Adjusting the Auto Flap

The air-direction flap on the ceiling panel outlet can be adjusted as follows.

Adjust the flap to the desired angle using the remote controller. The flap also has an automatic air-sweeping mecha- nism.

NOTE

Never attempt to move the flap by hand.

Proper air flow depends on the location of the air conditioner, the layout of the room and furniture, etc. If cooling or heating seems inadequate, try changing the direction of the air flow.

3-7. Wiring Instructions

General precautions on wiring

(1)Before wiring, confirm the rated voltage of the unit as shown on its nameplate, then carry out the wiring closely following the wiring diagram.

(2)Provide a power outlet to be used exclusively for each unit, with a power supply disconnect and circuit breaker for overcurrent protection provided in the exclu- sive line.

(3)To prevent possible hazards due to insulation failure, the unit must be ground- ed.

(4)Each wiring connection must be done tightly and in accordance with the wiring system diagram. Wrong wiring may cause the unit to misoperate or become damaged.

(5)Do not allow wiring to touch the refrigerant tubing, compressor, or any moving parts of the fan.

(6)Unauthorized changes in the internal wiring can be very dangerous. The manu- facturer will accept no responsibility for any damage or misoperation that occurs as a result of such unauthorized changes.

3-8. Recommended Wire Length and Diameter

Regulations on wiring diameter differ from locality to locality. For field wiring require- ments, please refer to your local electrical codes. Carefully observe these regula- tions when carrying out the installation.

Table 4 lists recommended wire lengths and diameters for power supply systems.

NOTE

Refer to the wiring system diagram (Fig. 7a or Fig. 7b) for the meaning of (A), (B) and (C) in Table 4.

Refer to your local codes or in the absence of local codes see the National Electric

Code: ANSI/NFPA70.

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.
