3-7. Wire Size and Length

Regulations on wiring diameter differ from locality to locality. For field wiring requirements, please refer to your local elec- trical codes. Carefully observe these regulations when carrying out the installation.

NOTE

Refer to the wiring system diagram (Fig. 23) for the meaning of (A), (B), and (C) in Table 5.

Refer to your local codes or in the absence of local codes see the National Electric Code: ANSI/NFPA70.

(*1) It depends on supply voltage level and wire specification. Consider temperature rating of wire, ambient temperature, and the number of wires inside the conduit.

(*2) Requirement of supply voltage level: AC187V to 253V (Measure voltage level at terminal plate inside the outdoor unit.)

WARNING

Be sure to comply with local codes on running the wire from the indoor unit to the outdoor unit (size of wire and wiring method, etc.).

Each wire must be firmly connected.

No wire should be allowed to touch refrigerant tubing, the compressor, or any moving part.

WARNING

To avoid the risk of electric shock, each air conditioner unit must be grounded.

For the installation of a grounding device, please observe local electrical codes.

Grounding is necessary, especially for units using inverter circuits, in order to release charged electricity and electrical noise caused by high tension. Otherwise, electrical shock may occur.

Place a dedicated ground more than 7' (2 m) away from other grounds and do not have it shared with other elec- tric appliances.

*NOTE

Disconnect switch may be required by national or local codes.

CAUTION

Always comply with national and local code requirements.

Be sure to connect the power supply line to the outdoor unit as shown in the wiring diagram. The indoor unit draws its power from the outdoor unit.

Do not run wiring for antenna, signal, or power lines of television, radio, stereo, telephone, security system, or intercom any closer than 3'4" (1 m) from the power cable and wires between the indoor and outdoor units. Electrical noise may affect the operation.

CS-KE30NKU, CS-KE36NKU, CU-KE30NKU, CU-KE36NKU specifications

The Panasonic CU-KE36NKU, CS-KE36NKU, CU-KE30NKU, and CS-KE30NKU air conditioning units represent the brand's commitment to delivering high-performance cooling solutions backed by innovative technologies. These units cater to both residential and commercial applications, ensuring users experience maximum comfort throughout the year.

One of the standout features of these models is their energy efficiency. Both units are equipped with advanced inverter technology, which allows for variable speed operation. This means they can adjust their power output according to the room's cooling needs, reducing energy consumption and minimizing electric bills while maintaining a consistent temperature. The models boast impressive SEER (Seasonal Energy Efficiency Ratio) ratings, making them environmentally friendly options.

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.
