FAQ
DO THE FILTERS NEED TO BE REPLACED?
The Venta Kuubel XL-T removes hazardous substances from the air
with the help of a VENTAcel lter. The lifespan of the VENTAcel lter
depends on the number of operating hours and the air quality in the
room. In general, with 24/7 operation, the lter needs to be replaced
every 6 months (a reminder will appear on the interactive display).
The pre-lter never needs to be replaced and can be rinsed under
fresh water or cleaned with a vacuum every 1 to 2 months or as
needed.
DOES THE KUUBEL XL-T HAVE AN AUTOMATIC MODE?
Yes. In “Auto” mode, which can be activated via the interactive dis-
play screen, the unit will automatically raise or lower the speed of the
fan to regulate the humidity to the optimal level of 50 %.
CAN THE DEVICE BE SWITCHED OFF AUTOMATICALLY AFTER A
SPECIFIED TIME?
Yes. By setting the “Timer” function on the interactive display screen
to a specied number of hours (1 / 3 / 5 / 7 / or 9), the unit will auto-
matically turn o after the specied number of hours have elapsed.
DOES THE KUUBEL XL-T EMIT RADIATION?
The Kuubel XL-T meets all standards regarding electromagnetic
elds (EMF). It is strongly recommended to operate the unit accor-
ding to Venta’s operating instructions. The operating instructions are
included in the original manufacturer’s box or can be downloaded
from the Venta website at any time.
THERE IS NO AIR COMING OUT OF THE AIR OUTLET. WHAT CAN I DO?
First, check to make sure that all protective foil and packaging has
been removed from the VENTAcel lter.
Then check to make sure the unit is plugged into a working standard
outlet and the power is on.
If the air quality in the room is good and “Auto” mode is activated,
the unit will automatically reduce the airow to save energy.
THE AIR FLOW COMING OUT OF THE KUUBEL XL-T IS MUCH WEAKER
THAN BEFORE. WHAT CAN I DO?
Please check to see if the pre-lter is polluted and clean the pre-lter
if necessary.
Check the display screen. If a “Change Filter” message appears, the
VENTAcel lter should be exchanged.
Make sure that all protective foil and packaging has been removed
from the VENTAcel lter prior to installation.
THE AIR QUALITY IS NOT IMPROVING, EVEN THOUGH THE UNIT HAS
BEEN IN OPERATION FOR A LONG TIME. WHAT CAN I DO?
Make sure that all lters are inserted properly in the following se-
quence from inside to outside: 1) VENTAcel lter 2) Pre-lter.
The Kuubel XL-T works best in a closed environment. Make sure all
windows and doors are closed to ensure the unit is optimally purify-
ing the room.
The display screen indicates that I must exchange the lter, even
though I‘ve already done this. What can I do?
Make sure that the VENTAcel lter as well as the VENTA pre-lter are
inserted correctly.
Next, press and hold the OK-button on the display screen for 3
seconds until a short signal sound is heard and the indication on the
display disappears.
THE KUUBEL XL-T IS NOT WORKING. WHAT CAN I DO?
Make sure that the Kuubel XL-T is securely and properly connected
to a working electrical outlet.
THE KUUBEL XL-T IS RUNNING, BUT THE INTERACTIVE DISPLAY
SCREEN IS NOT REACTING.
Check if the “Child Lock” function is activated. When activated, this
function disables the display screen controls. To deactivate, press
and hold the “Child Lock” button for 3 seconds.
WHY IS HUMIDIFICATION NOT TAKING PLACE?
Please check the interactive display screen to make sure that “Humi-
dity” is not set to “OFF”.
The “Fill Tank” display is glowing red.
Make sure that the water tray is inserted properly and there is water
in the tank.
If the problem persists, please contact the VENTA customer service
department at info@venta-usa.com or 1-888-333-8218.
CAN THE FILTERS BE WASHED?
Only the pre-lter can be cleaned. It can be rinsed under fresh water
or cleaned with a vacuum. Make sure the pre-lter is completely dry
before installation.
The other lters (VENTAcel / VENTAcarb) can NOT be washed or
cleaned with a vacuum cleaner.
WHAT ADVANTAGES DOES THE VENTACARB FILTER OFFER?
The VENTAcarb is an activated carbon lter that is inserted into the
VENTAcel lter and lters out odors and gases.
IS THE KUUBEL XL-T EFFECTIVE AGAINST TOBACCO SMOKE?
Yes, the Kuubel XL-T is eective in removing tobacco smoke and
odor. For the best results, allow the unit to run continuously on
the highest speed overnight after the smoking has ended. In the
morning, the air will be clean of any stale smoke and odor. For even
better and faster results, insert a VENTAcarb lter into the VENTAcel
lter.
WHAT IS THE FUNCTION OF THE VENTA HYGIENE DISC?
The Hygiene Disc maintains hygienic operation and prevents mineral
deposits (lime, calcium, etc.) from forming and hardening within the
unit.
WHY SHOULD NO OTHER ADDITIVES BE USED?
The only additives and accessories approved for use in the Kuubel
XL-T are those oered by Venta. They have been designed and
formulated specically to coordinate with the high-grade Venta plas-
tics. Additives, oils, and cleaners produced by other manufacturers
can have a corrosive eect on the plastic of the Kuubel XL-T. Venta
assumes no liability for damage caused by products from other
manufacturers
