6.1

Preparation for wall installation (surface mounted)

The fan is delivered as a complete unit, i.e. ready for connection, as standard. The installation and start-up of the fan
should take place after the completion of all other works and after the final cleaning, in order to prevent damage and
contamination of the ventilation unit.
After the removal of packaging and the start of installation, the following points must be checked:
– is there any transport damage,
– broken or bent parts
– freewheeling of the impeller
6.2 Installation
The M1/150 MiniVent is designed for direct wall installation. The housing must not be deformed or warped during
installation, and the flat structure of the installation surface must be ensured. The fans must only be installed on suffi
ciently solid and stable subsurfaces with suitable fastening materials. Sufficient backflow must be ensured! If applicable,
observe instructions in DIN 1946-6.
1. Cable exit from the wall
- The location of the cable outlet varies in the dark area (fig.5).
- Distance to the duct centre depending on cable exit r = 83 mm with a variable position of 0 to 360°.
- For a simple assembly an exit is recommended as shown (turnable by 90° in each case).
The optimal position is 45° each if the cable exit is directly at the position of the cable grommet.
- Duct inside diameter M1/150 = Ø 150 mm
- Distance to room corners: at least 130 mm from the duct centre
- With regard to surface mounted cabling, the side entry knockout for the cable (fig.8, Pos ➀) in the casing must be
broken out!
