FAQ

THE AIR FLOW COMING OUT OF THE KUUBOID XL MAX IS MUCH WEA-
KER THAN BEFORE. WHAT CAN I DO?
Please check to see if the pre-lters are polluted and clean the pre-
lters if necessary.
Check the display screen. If a “Change Filter” message appears, the
VENTAcel lters should be exchanged.
Make sure that all protective foil and packaging has been removed
from the VENTAcel lters prior to installation.
THE AIR QUALITY IS NOT IMPROVING, EVEN THOUGH THE DEVICE 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 Kuuboid XL MAX works best in a closed environment. Make
sure all windows and doors are closed to ensure the unit is optimally
purifying the room.
THE DISPLAY SCREEN INDICATES THAT I MUST EXCHANGE THE
FILTERS, EVEN THOUGH I‘VE ALREADY DONE THIS. WHAT CAN I DO?
Make sure that the VENTAcel lters as well as the VENTA pre-lters
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 KUUBOID XL MAX IS NOT WORKING. WHAT CAN I DO?
Make sure that the Kuuoid XL MAX is securely and properly connec-
ted to a working electrical outlet.
CAN THE FILTERS BE WASHED?
Only the pre-lters can be cleaned. They can be rinsed under fresh
water or cleaned with a vacuum. Make sure the pre-lters are com-
pletely 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 KUUBOID XL MAX EFFECTIVE AGAINST TOBACCO SMOKE?
Yes, the Kuuboid XL MAX is eective 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 VENTAcarb lters into the VENTAcel
lters.

I SEE SEVERAL WI-FI NETWORKS (“SELECT NETWORK”). WHICH ONE
SHOULD I CHOOSE?
1. The one with the name issued by you
2. The Wi-Fi network named on the back of the router
3. The strongest one in your listing
WHICH “SECURITY TYPE” ENCRYPTION SHOULD I CHOOSE?
1. Preferably the one that is recommended. By default this is WPA2/
PSK
2. The one that was indicated during the Wi-Fi set-up
3. The one indicated on the rear of the router
THE WI-FI SYMBOL IS NOT TURNING GREEN.
You have selected the wrong Wi-Fi network. Make sure that you are
choosing the right Wi-Fi network.
You have selected the wrong encryption. Check the type of encryp-
tion used in your Wi-Fi network.
Your password (“PSK” (ASCII input mode)) is wrong. Make sure that
your password is correct. Enter your password again. If your pass-
word contains special characters that are not represented on the
keyboard, you can generate your entire password as a HEX code at
the following website: www.venta-usa.com
Now enter your generated HEX code into the “PSK” eld (HEX input
mode) and conrm it with the ENTER key. Under “Access”, select the
internet access privileges you desire.
I CAN‘T FIND A WI-FI NETWORK
Check that your Wi-Fi network is switched on. Usually an LED with
the designation Wi-Fi glows on the router.
Check if your Wi-Fi network is set to „visible“ in the router. In the
“Select network” eld, enter the Wi-Fi network name that you know
or that is indicated on the back of the router. Then select WPA2/PSK
encryption and enter the Wi-Fi -key (either the known key or the one
on the back of the router).
Does your router support the 802.11a/b/g or n standard? This can
only be specied via the type of the router (technical data), LW-Wi-Fi
only supports 802.11a/b/g/n
