VK 102 / VK 103 AIR PURIFIER

Dear Customer

Thank you for purchasing the VK 102 or VK 103 Air Purifier. This product utilizes advanced clean air technology to provide fast and efficient clean air. We hope you enjoy using your new unit!

The Viruskiller technology has been tested against major airborne viruses including Poliovirus, Influenza Virus, Adenovirus, and Coronavirus DF2 by the Institute of Medical Sciences, School of Medicine National Kangwon University. Testing proves a near 100% reduction for these viruses. The results for these airborne pathogens are consistent across the entire Viruskiller range.

Radic8's Viruskiller range (Hextio, VK 401, VK 102, and VK 103) is not FDA-cleared / FDA-approved.

INSTALLATION SAFETY

• Should the unit emit smoke, unusual odors, or make any strange noises, immediately switch off the unit and unplug it. Contact your distributor.
• No form of water or liquid should enter the unit. Should this occur, immediately switch off the unit and unplug it. Contact your distributor.
• Do not place any heavy objects on the power cord, as this may cause a fire and/or an electric shock. [image of heavy object on cord with prohibition symbol]
• Make sure the power cord is plugged firmly into the outlet. If the power is not plugged in correctly, this may cause a fire. [image of plug being inserted]
• Do not touch the plug with wet hands, as this may cause serious injury. [image of hand touching plug with prohibition symbol]
• Do not block the air inlet of the unit, as this will reduce the airflow and result in poor performance and damage the unit. [image of blocked air inlet with prohibition symbol]
• Do not spray inflammable materials near the unit, as this is a fire hazard. [image of spray can with prohibition symbol]
• Do not sit, stand, or place heavy objects on the unit, as this may result in injury and/or damage to the unit. [image of person on unit with prohibition symbol]
• Do not move the product while it is switched on, as this may cause a fire and/or an electric shock. [image of unit being moved while on with prohibition symbol]
• Do not alter or modify the plug or cord of this unit, as it could cause a fire or an electric shock. [image of modified plug with prohibition symbol]
• Use the proper power cable and outlet; do not overload the outlets with several cords simultaneously. [image of overloaded outlet with prohibition symbol]
• Keep the product away from inflammable gases, liquids, or other combustible substances, as this could cause an explosion. [image of gas can with prohibition symbol]
• To protect against a risk of electric shock, do not immerse any part of the system in water or in any other liquids. [image of unit in water with prohibition symbol]
• Do not attempt to repair or replace any part of this equipment unless it is specifically recommended in this manual. All other services should be referred to a qualified technician. [image of repair with prohibition symbol]
• Plug the unit into a 220V AC outlet only. If unsupervised, it may cause an electric shock. [image of 220V plug]
• Switch the unit OFF when cleaning a room. After cleaning, it is important to ventilate the room properly before switching the unit back ON. [image of cleaning with unit off]
• Switch the unit OFF while cooking. Oils released while cooking may reduce the life span of the unit. After cooking, the room must be ventilated to remove oils. You may now switch the unit ON to remove any smells. [image of cooking with unit off]
• Airflow must NOT be restricted or obstructed by large items such as furniture, electronic items, or curtains. [image of blocked airflow with prohibition symbol]
• Daily room ventilation for at least 30 minutes. The unit is designed to purify your indoor air and will do this effectively when used correctly. Good indoor air quality also requires room ventilation. We recommend opening windows and doors, or operating the air conditioning, for at least 30 minutes a day. [image of open window]
• Position the unit at least 3 meters away from the bed, to avoid excessive cooling caused from sleeping in direct airflow. [image of bed with unit 3m away]
• Use a dedicated power outlet. Lightning or static electricity could affect the circuit and may cause a fire or damage the unit. To avoid this, plug the unit into a dedicated, grounded outlet. [image of dedicated outlet]

CLEANING AND MAINTENANCE

CLEANING THE PRE-FILTER

VK 102

The plastic pre-filter is reusable. To clean it, follow this procedure:

1. Pull out the filter case ①.
2. Remove pre-filter ② from filter case and separate from carbon filter ③ and HEPA filter ④.
3. Clean the pre-filter with a vacuum cleaner.
4. Place the filter back into the filter case.

VK 103

The plastic pre-filter is reusable. To clean it, follow this procedure:

1. Pull out the bottom filter case ①.
2. Remove pre-filter ② from filter case and separate from carbon filter ③ and HEPA filter ④.
3. Clean the pre-filter with a vacuum cleaner.
4. Place the filter back into the filter case.
5. Repeat the process for the top filter case ⑤.

Replacing the HEPA filter

When the Filter LED light changes to RED, it is time to replace the HEPA and Carbon filters. The HEPA and Carbon filters are not reusable and should be replaced. Please contact your distributor to purchase replacement HEPA and Carbon filters. Depending on the levels of pollution, the lifetime of the HEPA filter may be longer or shorter than the recommended use times below:

• HEPA filters (hrs): 6000
• Carbon filters (hrs): 6000

Procedure:

1. Pull out the bottom filter case ①.
2. Separate the carbon filter ③ and HEPA filter ④ from the pre filter ②.
3. Replace them with new filters.
4. Place them back into the filter case.
5. For the VK 103: Repeat the process for the top filter case ⑤.
6. Press the UP button on the Display for at least 5 seconds, to reset the Filter timer to zero.

Replacing the Reactor Cell

In order for the VK 102 and VK 103 to remain functional, the reactor chamber must be replaced every 8000 hours. Your unit will indicate that a change is required by displaying a "-0001" code on the LED Display.

1. From the top PCB board ⑪, disconnect the 2 cables connecting the reactor cell to the back of the unit ②.
2. On the side, you will see 2 long cables connecting the reactor cell to the bottom right of the unit. One cable is red and yellow, while the other one is black and white. Disconnect these cables and bring them to the front of the unit.
3. Remove the 2 screws on the top ⑤ and 3 screws on the bottom ⑥, which attach the reactor cell to the unit.
4. You can now remove the old reactor cell, making sure no wires are still connected to the main unit.
5. You must now separate the top white part ④, holding the PCB board, from the old reactor cell and move it to the new reactor cell. First, unscrew the top 4 screws ⑤, that attach the white, metal box to the old reactor cell.
6. Unscrew the 2 screws holding the component marked with ⑥, and disconnect the wires.
7. Now carefully lift the top part, holding the PCB, and mount it on the new reactor cell in reverse order. Then place the new reactor cell inside the unit and assemble in reverse order.
8. Now switch your VK 102 or VK 103 back on, press and hold the down button for 14 seconds, to reset the warning timer. Your VK 102 or VK 103 is ready for the next 8000 hours.

Cleaning the Air Quality Sensor (IAQ Sensor)

The IAQ sensor is a very delicate instrument that uses light scattering to detect pollution. It therefore needs a clean lens to work effectively. Regular maintenance (every 6 months) should be carried out to keep the lens clean.

Important - Only use pure water and allow to dry completely before replacing. To avoid damage to the plastic lens, do not use chemicals such as benzene or alcohol etc.

Procedure to maintain and clean the IAQ Sensor:

• Locate the IAQ sensor on the side of the unit.
• Clean lens with a clean cotton swab dampened with pure water as shown in the image on the right.
• Allow lens to dry completely.
