2 Systemair recommends that the product is installed to-
gether with a roof curb (A). Roof curbs are available as
an accessory. If a roof curb is used, do these steps:
a. Install the roof curb on the roof (B).
b. Make sure that the installation is weatherproof, and
that all installation surfaces are sealed.
c. Install the fan on the roof curb.
Note:
Obey local laws and regulations for installation of the roof
curb on the roof.
3 Install the duct and attach the product, with the installed
FTG tilting device, on the top of the roof curb.
4 Tighten the fast clamps around the duct connections and
the product with the supplied screws.
5 Examine if the fan and accessories make a thermal
bridge. If they do, use vinyl rubber as an insulation of the
fan and accessories. Make sure that the vinyl rubber, for
example Armaflex, is sufficiently thick to prevent
condensation.
Note:
Install the product so that unwanted vibrations are not
transmitted to duct systems or roof beams.
Note:
When the product is installed together with installation ac-
cessories, make sure that all mounting surfaces are
sealed air tight.
4.2.2 To connect the product to the
ventilation system
1 Systemair recommends to connect the duct (D) to a flexi-
ble connection (C), an inflow box (B) and a back draft
damper (A).
