Switch the unit OFF, when
cleaning a room.
After cleaning, it is important
to ventilate the room properly
before switching the unit back
ON.
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.
Switch the unit OFF, while
cooking.
Oils released while cooking may
reduce the life span of the ster-
ilizer. After cooking, the room
must be ventilated to remove
oils. You may now switch the
unit ON to remove any smells.
Position the unit at least 3
meters away from the bed,
to avoid excessive cooling
caused from sleeping in direct
airow.
Airow must NOT be
restricted or obstructed,
by large items such as fur-
niture, electronic items or
curtains.
Use a dedicated power outlet.
Lightning or static electricity
could affect the circuit and
may cause a re or damage
the unit. To avoid this, plug the
unit into a dedicated, grounded
outlet.
Do not alter or modify the plug
or cord of this unit as it could
cause a re or an electric
shock.
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 equip-
ment unless it is specically
recommended in this manual.
All other services should be re-
ferred to a qualied technician.
Plug the unit into a 220V AC
outlet only, if unsupervised, it
may cause 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
inammable gases, liquids, or
other combustible substances,
as this could cause an explo-
sion.

The plastic pre-lter is reusable. To clean it,
follow this procedure:
1. Pull out the bottom lter case ①
2. Remove pre-lter ② from lter case ①and
separate from carbon lter ③ and HEPA lter ④.
3. Clean the pre-lter with a vacuum cleaner.
4. Place the lter back into the lter case.
5. Repeat the process for the top lter case ⑤
1. Pull out the bottom lter case ①
2. Separate the carbon lter ③ and HEPA lter
④ from the pre lter ②
3. Replace them with new lters.
4. Place them back into the lter case.
5. Repeat the process for the top lter case ⑤
6. Press the UP button on the Display for at least
5 seconds, to reset the Filter timer to zero.
CLEANING AND MAINTENANCE
HEPA lters (hrs) 6000 Carbon lters (hrs) 6000
When the Filter LED light changes to RED, it is time to replace the HEPA and Carbon lters. The
HEPA and Carbon lters are not reusable and should be replaced. Please contact your distributor to

Replacing the Reactor Cell
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. From the top PCB board ①, 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 con-
necting 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 the front of the
unit.
3. Remove the 2 screws on the ③top and 3
screws on the bottom, which attach the reac-
tor 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 reac-
tor 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 com-
ponent marked with ⑥, and disconnect the
wires ⑦.
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 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.

Cleaning the Air Quality Sensor (IAQ Sensor)
Cleaning the Indoor Air Quality (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.
