1.3 Mounting on the wall
The standard model of HRV includes mounting brackets to ensure easy and secure mounting of the device
to the wall. Low noise operation of HRV can be achieved by avoiding of its installation on bedroom walls,
hollow or resonating walls.
It is advisable to install HRV on the load-bearing walls whenever possible. If installation of HRV on the load-
bearing wall is not possible, use, for example, a plywood sheet between the HRV and the non-bearing
wall.
Installation steps
1. Mount the lower bracket on the wall, pay attention to the correct height of installation and whether the
chosen wall is load-bearing.
2. Lift and set the device on the lower mounting brackets; this will also facilitate the installation process.
3. Fasten the upper mounting screws, note the structure of the wall (differs for load-bearing and non-bearing
walls as noted above)
Mounted HRV should be slightly reclined backwards to ensure drainage of possible condensed water. The
rear side of the HRV bottom should be at least 2 mm lower than the front side. Reclining can be done during
the installation by moving the backside slightly downwards, the oval-shaped holes of the brackets allow to
do the adjustment.
