1. Introduction
The ReSPR FLEX is a compact, next-generation air purification system designed to improve indoor air quality. Utilizing advanced NCC (Natural Catalytic Conversion) technology, originally adopted by NASA for the International Space Station, it actively generates ions and ozone from ambient moisture and oxygen. This process effectively addresses viruses, bacteria, and other airborne contaminants, making your environment cleaner and safer. The ReSPR FLEX is suitable for areas up to 280 square meters (approximately 30 tatami mats).

2. Safety Information
Please read all safety instructions carefully before operating the ReSPR FLEX. Failure to follow these instructions may result in electric shock, fire, or serious injury.
- Do not immerse the unit in water or any other liquid.
- Do not operate the unit with a damaged power cord or plug.
- Keep the unit away from heat sources, direct sunlight, and flammable materials.
- Ensure proper ventilation around the unit during operation.
- Do not block the air inlets or outlets.
- Unplug the unit before cleaning or performing any maintenance.
- This appliance is not intended for use by persons (including children) with reduced physical, sensory or mental capabilities, or lack of experience and knowledge, unless they have been given supervision or instruction concerning use of the appliance by a person responsible for their safety.
3. Product Overview and Technology
The ReSPR FLEX utilizes NCC (Natural Catalytic Conversion) technology to purify the air. This innovative system actively releases purifying agents into the environment, rather than just filtering air that passes through the unit.
3.1 NCC Technology Explained
The core of the ReSPR FLEX is its NCC cell, which contains a broad-spectrum UV lamp and a special metal coating. When air, containing moisture (H₂O) and oxygen (O₂), passes through the cell, the UV light and catalytic surface react with these elements to produce various oxidizing agents, including hydroxyl radicals (OH⁻), superoxide ions (O₂⁻), and low levels of ozone (O₃).

Figure 3.1: Diagram illustrating the NCC cell structure and the heterogeneous photocatalyst mechanism. The diagram shows how H₂O and O₂ enter the cell, react with the UV lamp and coated metal, and are transformed into purifying ions and ozone.
3.2 Active Air Purification
Unlike traditional air purifiers that rely on passive filtration, the ReSPR FLEX actively disperses these purifying agents throughout the treated area. These agents then seek out and neutralize contaminants in the air and on surfaces, including viruses, bacteria, mold, and odors.

3.3 ReSPR is an Air Purification System, Not Just a Filter
It is important to understand that ReSPR FLEX is not merely an air filter. It is an advanced air purification system designed to actively clean the air and surfaces in your environment.

4. Setup
Follow these steps to set up your ReSPR FLEX unit:
- Unpack the Unit: Carefully remove the ReSPR FLEX from its packaging. Retain the packaging for future storage or transport.
- Choose a Location: Place the unit on a flat, stable surface in the area you wish to purify. Ensure there is adequate space around the unit for proper airflow. The ReSPR FLEX is versatile and can be used in various settings.
- Power Connection: Plug the power adapter into the unit's power input, then plug the adapter into a standard electrical outlet.
- Initial Power On: The unit may perform a brief self-check upon first power-on.

5. Operating Instructions
The ReSPR FLEX features a user-friendly control panel for easy operation.
- Power Button: Press the POWER button to turn the unit ON or OFF.
- Fan Speed Control: Use the FAN button to cycle through different fan speeds (e.g., Low, Medium, High) to adjust the purification intensity and noise level.
- Mode Selection: The unit may offer different operating modes such as HIGH MODE for maximum purification or AWAY MODE for enhanced treatment when the area is unoccupied. Refer to the display for current mode indication.
- Display: The digital display provides information such as current fan speed, operating mode, and maintenance alerts (e.g., "PERFORM CLEANING REPLACE CELL").
For optimal performance, it is recommended to operate the ReSPR FLEX continuously, especially in areas with persistent air quality concerns.
6. Maintenance
Regular maintenance ensures the longevity and efficiency of your ReSPR FLEX unit. The unit's display will indicate when maintenance is required, typically showing "PERFORM CLEANING REPLACE CELL".
- Cleaning the Unit:
- Unplug the unit from the power outlet before cleaning.
- Wipe the exterior of the unit with a soft, damp cloth. Do not use abrasive cleaners or solvents.
- Gently vacuum or brush any dust from the air inlets and outlets.
- Replacing the NCC Cell:
- The NCC cell has a limited lifespan and will need periodic replacement to maintain purification effectiveness.
- When the display indicates "REPLACE CELL", order a genuine ReSPR replacement cell.
- Refer to the detailed instructions provided with the replacement cell for proper installation.
- After replacing the cell, reset the unit's maintenance indicator as per the instructions in the replacement cell manual.
7. Troubleshooting
If you encounter issues with your ReSPR FLEX, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Unit does not power on. | No power supply; power cord not properly connected. | Ensure the power cord is securely plugged into both the unit and a working electrical outlet. Check the power outlet with another device. |
| Air purification seems ineffective. | NCC cell needs cleaning or replacement; blocked air vents. | Check the display for "PERFORM CLEANING REPLACE CELL" message. Clean the unit and replace the NCC cell if indicated. Ensure air inlets and outlets are not obstructed. |
| Unusual noise from the unit. | Fan obstruction; unit not on a stable surface. | Check for any foreign objects obstructing the fan. Ensure the unit is placed on a flat, stable surface. If noise persists, contact customer support. |
If the problem persists after trying these solutions, please contact customer support.
