VK Medi Air Steriliser

Dear Customer
Thank you for purchasing the VK Medi Air Purifier, this is clean air technology at its best. This product is packed with power and technology to provide fast and efficient clean air. We hope that you enjoy using your new unit! The Viruskiller technology was tested against the following major airborne viruses: 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 the same for all of the Viruskiller range.
Radic8’s Viruskiller range (Hextio, VK 401, VK 102, VK 103 and VK Medi) is not FDAcleared / FDA-approved.

USER GUIDE AND INSTRUCTIONS

Warning – Indicates important safety instructions that must be followed to avoid injury.
Caution – Indicates important information to your attention to avoid the risk of injury or damage to the unit
Prohibited – Indicates forbidden action

INSTALLATION SAFETY

Should the unit emit smoke,

unusual odors or make any

strange noises, immediately

switch off the unit unplug it.

Contact your distributor.

this may cause a fire and/or
an electric shock.
Make sure the power cord is
plugged firmly into the outlet.
If the power is not plugged in
correctly, this may cause a fire| Do not touch the plug with
wet hands, as this may cause
serious injuries.| Do not block the air inlet of
the unit, as this will reduce the
airflow and result in poor performance
and damage the unit.
Do not spray inflammable
materials near the unit, as this
is a fire hazard.| Do not sit, stand or place heavy
objects on the unit, as this may
result in injury and/or damage
to the unit| Do not move the product while
it is switched on. as this may
cause a fire and/or an electric
shock.
Do not alter or modify the plug
or cord of this unit as it could
cause a fire or an electric
shock.| Use the proper power cable
and outlet, do not over-load
the outlets with several cords
simultaneously.| Keep the product away from
inflammable gases, liquids, or
other combustible substances, as this
could cause an explosion.
To protect against a 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 from sleeping in direct
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.

CLEANING AND MAINTENANCE

CLEANING THE PRE-FILTER

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 ① 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

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. 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 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 .

1. Disconnect all wires from the PCB board ①.
2. 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.
3. Remove the component marked with ②, by unscrewing the 2 screws, and disconnect it from the reactor chamber. You will need to install this on the new reactor chamber.
4. 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.
5. Next, place the new reactor chamber inside the main unit and secure it with the 5 screws.
6. 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)
7. 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.
