Daily room ventilation for at
least 30 minutes.
The unit is designed to purify
your indoor air and will do this
effectively when used correct-
ly. 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
unit. After cooking, the room
must be ventilated to remove
oils. You may now switch the
unit ON to remove any smells.

on a weekly basis. The plastic pre-lter is reusable, to clean it follow the procedure below:
• Open the handle at the top of the unit ①. Gently slide the lter case out of the top of the unit ②..
• Slide out and separate the pre-lter ③ from the HEPA lter ④. Ensure you have removed the HEPA lter be-
fore washing the pre-lter.
• Clean the pre-lter by using a vacuum cleaner. Cleaning with warm water is also possible, however allow the
lter to dry completely before reinstalling.
You can now put the lters back into the case and place this back into your VK 401. Make sure that the carbon part
of the lter is facing the back on the unit. Close the lter handle, and the unit can be switched back on.
REPLACING THE SIDE CARBON FILTERS
Ensure that the unit is switched OFF and unplugged, unscrew and open the side lter door ⑤and replace the carbon
lter inside, then close the door, reinsert the screw and tighten.
The HEPA and Carbon lters are not reusable and should be replaced. Please contact your distributor to purchase
replacement HEPA and Carbon lters. Depending on the levels of pollution, the lifetime of the HEPA lter may be
longer or shorter than the recommended use times below:

Cabinet Interior Light
The cabinet interior side light is tted with one 35Watt T5 uorescent tube (Ø16mm x 1450mm, Daylight 840), which
may be replaced without removing shelves or product from the cabinet. To replace the uorescent tube:
1. Disconnect the cabinet from the mains power supply.
2. Remove the side light di󰀨user, by compressing the back section of the di󰀨user until it disengages from the alu-
minium housing and then push the di󰀨user back (see Figure 9 below).
3. The uorescent tube can now be removed. Revolve the tube until the pin position allows withdrawal.
4. When retting the new uorescent tube ensure the printing on the tube is at the bottom, as the tube orientation
is important. The replacement tube must be of the same wattage and colour rendering as the original.
5. When retting the di󰀨user, engage the back section into the housing and then compress and snap the front sec-
tion of the di󰀨user into place, working down the full length of the housing.
