Introduction
This guidebook provides comprehensive installation and service information for the Panasonic R32 Inverter Air Conditioner NX series. It highlights advanced features such as nanoeX Technology for enhanced air quality, Pre-Cool On The Go functionality, and tools for checking energy consumption. The series offers innovative solutions for various commercial applications.
New Model Features
1. Cassette Type
The 4-Way Cassette type features a 360-degree wide airflow system, directing air farther from the center and spreading it across the room via wide side flaps. It offers long airflow up to 5 meters due to an improved flap design that reduces turbulence. Key information includes:
- ✨ nanoeTM X Technology for air purification.
- Compact and Lightweight Design.
- DC Fan Motor for increased efficiency.
- Powerful Drain pump with an 850 mm lift capability.
2. Adaptive Ducted
This type offers Flexible Installation, including vertical mounting and a compact body with 150 Pa ESP (External Static Pressure). Bottom suction is also available. Basic information includes:
- ✨ nanoeTM X Technology.
- Capacity range from 17,100 to 47,800 Btu.
- Static pressure level: 10-150 Pa.
- Height: 250 mm.
- DC fan motor.
- Built-in drain pump.
- Filter included.
Flexible Installation Details: The ducted unit can be mounted vertically, allowing for discreet placement even in spaces with limited ceiling height. It features a shared drain pan for both horizontal and vertical installations. The compact body (250mm height, 30kg weight for 1.5/2HP models) is lighter than conventional models (290mm height, 31kg). The air inlet angle is adjustable, supporting both rear and bottom suction.
3. Outdoor Unit
Key features of the outdoor unit include High Durability, with all Panasonic heat exchangers utilizing Blue Fin technology for enhanced corrosion resistance. It incorporates an in-house manufactured compressor, with over 580 million high-quality units supplied globally. The series uses Next Generation R32 Refrigerant, which has a very low potential impact on ozone depletion and global warming compared to R22 and R410A.
4. 24 hrs. nanoeTM X Protection
While general filters target airborne bacteria and viruses, nanoeTM X also inhibits longer-living, adhered bacteria and viruses. The CONEX remote control (CZ-RTC6BLW) allows users to activate nanoeTM X remotely, ensuring 24-hour quality air. This feature provides clean air independently when away (Fan Mode + nanoeTM X ON) and cool, clean air when in the room (Cooling Mode + nanoeTM X ON). It operates with low energy consumption, using only 25W/hour in fan mode for a single unit. The nanoeTM X generator device is maintenance-free, and its titanium electrodes are crafted by artisans in Japan. It functions effectively in cooling and fan modes without consuming excessive electricity.

Common Air Conditioning Problems
This section outlines common issues encountered with air conditioners and provides guidance on diagnosis and potential H&C Diagnosis parameters to check.
| No. | Case of Problem | Description | H&C Diagnosis Parameter Checking |
|---|---|---|---|
| 1 | Air conditioner not blowing cold air | A dirty air filter can block airflow, potentially freezing up the condenser unit and limiting cooling power. Regular filter changes (monthly recommended) help maintain airflow. | 1. Compressor frequency 2. Expansion Valve Step 3. Discharge Temperature 4. Liquid Temperature 5. Outdoor Current |
| 2 | Air conditioner Freezing up outside unit | Freezing can occur due to insufficient airflow, low outside temperature, low coolant levels, blower motor problems, or a stuck contactor. | 1. Outdoor Temperature 2. Outdoor Fan Motor Speed 3. Compressor frequency |
| 3 | Air conditioner refrigerant leak | Coolant leaks cause temperature variations and inaccurate performance, leading to low efficiency, high power consumption, coil freezing, damaged compressors, uneven cooling, and potential unit damage. Regular inspection for leaks is advised. | 1. Compressor frequency 2. Indoor H/E Liquid temperature (E1) 3. Indoor H/E Middle temperature (E2) 4. Error Code 5. Discharge Temperature (TD) 6. Liquid Temperature (C1) |
| 4 | Frozen evaporator coil | The evaporator coil freezes when the air conditioner does not receive sufficient airflow. Blocked vents, dirty filters, or a faulty fan can cause insufficient airflow. A clean air filter is crucial for maximizing airflow and indoor air quality. | 1. Compressor frequency 2. Room Temperature 3. Differential Temperature 4. Indoor H/E Liquid temperature 5. Indoor H/E Middle temperature |
| 5 | Electric control failure | Frequent on/off cycles can wear out fan controls and compressors. Electrical connection problems can prevent motors and compressors from starting. Checking electrical connections is necessary. | 1. Outdoor Current ampere (CT1) 2. Compressor frequency |
| 6 | Sensor problem | The thermostat sensor, located near the evaporator coil, measures air temperature and adjusts cooling. If displaced, the AC may cycle randomly. The sensor should be positioned near, but not touching, the evaporator coil. | 1. Setting Temperature 2. Room Temperature 3. Differential Temperature 4. Indoor H/E Liquid temperature 5. Indoor H/E Middle temperature 6. Outdoor Temperature 7. Discharge Temperature (TD) 8. Outdoor H/E Liquid temperature 9. Outdoor H/E Middle temperature |
