The SRT+ silencer, entirely made of sheet metal, is installed in all the linings after having made the circular hole in the wall and sealed a PVC sleeve Ø 125 mm. The installation is done inside the lining associated with an adjustment sleeve.
The SRT+ 30/57 model is associated with an ISOLA 22 or 30 m³/h self-regulating air inlet.
The SRT+ 45/54 model is associated with an ISOLA 45 m³/h self-regulating or ISOLA HY humidity-controlled air inlet.
Drill the wall and seal a PVC sleeve Ø 125 mm with a slight slope towards the outside.
On the exterior side, fit GEM the louvred grille once the coatings are finished.
Fix the silencer to the wall using the 2 fixing lugs located on the sides.
Do not forget to cover the walls of the SRT+ with insulation in order to avoid any thermal bridges.
The MPR sleeve must penetrate at least 10 mm into the SRT+. Implementation of SRT+ in linings with thicknesses of 90 + 10 to 110 + 10 mm.
For thicker linings, add a second adjustment sleeve.
