Mechanical installation
Aria fans can be wall mounted.
For mounting the fan, a ø100mm is required for the
spigot, as well as at least two holes for the mounting
screws. When mounting the fan, remove the front
cover and place the fan into the pre drilled hole. Make
sure that the spigot fits into any pre-installed ducting.
Wire the fan appropriately according to page 5,
ensuring that the cables from the fan are routed
through the provided cable hole.
Use at least two mounting screws to secure the fan to
the ceiling or wall ensuring not to over tighten and
replace the front cover with the retention screw.
Ensure free running of the fan impeller and that
flexible duct connections are not over tightened to the
fan outlet spigot.
Airflow recommends that rigid ducting is used instead
of flexible ducting, this will ensure maximum
performance
