Installation
• Arrange the exterior air supply from the shadowed side of
the dwelling, preferably from the wall or overhang. If the out
-
door air is sucked in from under the tiles, it must be ensured
that no condensation develops in the roof boarding and no
water can run in. Ventilation air can be sucked in from under
the tiles if air can access freely at the top and the bottom of
the roof area and the sewage vent stack does not end under
the tiles.
• Feed the extract duct through the roof boarding in such a
manner that no condensation develops in the roof boarding.
• Install the extract duct between the Ubiflux and the roof slee
-
ve in such a manner that surface condensation is prevented.
• Always use an insulated ventilation roof sleeve.
• The maximum permissible resistance in the duct system is
150 Pa (W300 & W400) and 100 Pa (W450) at the maximum
ventilation capacity. If the resistance of the duct system is
higher, the maximum ventilation capacity will be lower.
• The location of the mechanical ventilation output and the se
-
wer stack vent relative must be chosen to prevent nuisance.
• Choose the location of the supply valves to prevent fouling
and draught. We recommend to use the Ubbink supply val

ves.
Install sufficient overflow openings, door gap 2 cm.
