Three options for mounting the unit
1. Roof Installation
(Recommended duct length: 2-3 metre)
Mount the 100mm rigid PVC pipe securely to the beams, trusses or other appropriate structures, refer figure 1.
on the next page.
The pipe should be mounted either vertically or perpendicular to the roof cladding with the roof penetration
being sealed using a Dektite or other sealing device. Please note Schweigen do not provide any sealing kits.
Ensure that the pipe protrudes at least 80mm past the top of the Dektite, checking that the mounting flange
clears the roof cladding at upper edge as shown in figure 1.
The maximum recommended protrusion is 500mm. Fit mounting flange, refer figure 1, to pipe using silicon
sealant, then tape in position until sealant has set.
Fit fan module to the mounting flange by placing in position, rotating clockwise to engage bayonet fingers
and secure by screwing in locking screw (while holding fan module firmly in the fully clockwise position).
Please refer to page 12 (Figure 6)
