To protect against the risk of electric shock, do not immerse any part of the system in water or in any other liquids.
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.
Plug the unit into a 120V AC outlet only, if unsupervised, it may cause an electric shock.
Switch the unit OFF, when cleaning a room.
After cleaning, it is important to ventilate the room properly before switching the unit back ON.
Switch the unit OFF, while cooking.
Oils released while cooking may reduce the life span of the sterilizer. After cooking, the room must be ventilated to remove oils. You may now switch the unit ON to remove any smells.
Airflow must NOT be restricted or obstructed, by large items such as furniture, electronic items, or curtains.
Daily room ventilation for at least 30 minutes.
The unit is designed to purify and sterilize 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 a least 30 minutes a day.
Position the unit at least 3 meters away from the bed, to avoid excessive cooling caused by sleeping indirect airflow.
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.

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

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.
Repeat the process for the top filter case ⑤
Press the UP button on the Display for at least 5 seconds, to reset the Filter timer to zero.

Replacing the Reactor Chamber

In order for the VK Medi 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.

Disconnect all wires from the PCB board ①.
Unscrew the 4 screws holding the PCB board to the reactor cell and remove the PCB board. You will need to install this on the new reactor chamber.
Remove the component marked with ②, by unscrewing the 2 screws, and disconnecting them from the reactor chamber. You will need to install this on the new reactor chamber.
You can now remove the old reactor chamber, by unscrewing the 5 screws holding it to the main unit (marked with arrows). Make sure no wires are still connected to the main unit.
Next, place the new reactor chamber inside the main unit and secure it with the 5 screws.
Install the PCB board and the component marked with ②, and connect all the wires back. (see a diagram of all the connections on the last page of this manual)
You can now switch your VK Medi back on, press and hold the down button for 14 seconds, to reset the warning timer. Your VK Medi is ready for the next 8000 hours.
