Cleaning the Pre-Filter
The plastic pre-filter is reusable and can be cleaned.
VK 102 Procedure:
- Pull out the filter case (1).
- Remove pre-filter (2) from the filter case and separate it from the carbon filter (3) and HEPA filter (4).
- Clean the pre-filter with a vacuum cleaner.
- Place the filter back into the filter case.
[Diagram Description: Visual representation of filter case removal and pre-filter separation for VK 102, showing numbered parts.]
VK 103 Procedure:
- Pull out the bottom filter case (1).
- Remove pre-filter (2) from the filter case and separate it from the carbon filter (3) and HEPA filter (4).
- Clean the pre-filter with a vacuum cleaner.
- Place the filter back into the filter case.
- Repeat the process for the top filter case (5).
[Diagram Description: Visual representation of filter case removal and pre-filter separation for VK 103, showing numbered parts including a top filter case.]
Replacing the HEPA Filter
When the Filter LED light changes to RED, it is time to replace the HEPA and Carbon filters. These filters are not reusable and must be replaced. Contact your distributor for replacement filters. The lifetime of the HEPA filter may vary depending on pollution levels.
- HEPA filters (estimated use): 6000 hours
- Carbon filters (estimated use): 6000 hours
Replacement Procedure:
- Pull out the bottom filter case (1).
- Separate the carbon filter (3) and HEPA filter (4) from the pre-filter (2).
- Replace them with new filters.
- Place them back into the filter case.
- For the VK 103: Repeat the process for the top filter case (5).
- Press and hold the UP button (▲) on the Display for at least 5 seconds to reset the Filter timer to zero.
[Diagram Description: Visual representation of filter replacement for VK 103, showing numbered filter components being removed and replaced within the filter case.]
Replacing the Reactor Cell
The reactor chamber must be replaced every 8000 hours of operation for the VK 102 and VK 103 to remain functional. The unit will indicate this requirement by displaying a "-0001" code on the LED Display.
[Diagram Description: Control panel display showing "-0001" code.]
Replacement Steps:
- From the top PCB board (1), disconnect the 2 cables connecting the reactor cell to the back of the unit (2).
- On the side, disconnect the 2 long cables connecting the reactor cell to the bottom right of the unit. One cable is red and yellow, the other is black and white. Bring these cables to the front.
- Remove the 2 screws on the top and 3 screws on the bottom that attach the reactor cell to the unit.
- Remove the old reactor cell, ensuring no wires are still connected to the main unit.
- Separate the top white part (4), which holds the PCB board, from the old reactor cell. Move this part to the new reactor cell. First, unscrew the top 4 screws (5) that attach the white metal box to the old reactor cell.
- Unscrew the 2 screws holding the component marked with (6) and disconnect its wires.
- Carefully lift the top part (holding the PCB) and mount it onto the new reactor cell in reverse order. Place the new reactor cell inside the unit and assemble in reverse order.
- Switch your VK 102 or VK 103 back ON. Press and hold the down button (▼) for 14 seconds to reset the warning timer. Your unit is now ready for the next 8000 hours.

Numbered components indicate connection points and screws to be removed/attached: 1 (Top PCB board), 2 (Cables to back of unit), 3 (Screws), 4 (Top white part/PCB holder), 5 (Top screws for metal box), 6 (Component screws and wires), 7 (Wires).]
Cleaning the Air Quality Sensor (IAQ Sensor)
The IAQ sensor is a delicate instrument that uses light scattering to detect pollution. It requires a clean lens to function effectively. Regular maintenance (every 6 months) is recommended.
Important: Only use pure water and allow the lens to dry completely before use. Do not use chemicals such as benzene or alcohol, as they can damage the plastic lens.
Procedure:
- Locate the IAQ sensor on the side of the unit.
- Clean the lens with a clean cotton swab dampened with pure water, as shown in the illustration.
- Allow the lens to dry completely.
[Image Description: Side view of the air purifier showing the location of the IAQ sensor. A close-up shows cleaning the sensor lens with a cotton swab and pure water.]
