Installation instructions

ATTENTION: Damage to unit/functional problems in the event of rubbing impeller. Do not fit the flange sleeve either twisted or crushed. Make sure that the surface is level.

ATTENTION: Risk of short circuits/damage to unit if condensation builds up in the fan housing.

• Observe minimum wall thickness:
  EN 20, ENR 20, EN 25, ENR 25: 105 mm
  EN 31, ENR 31: 130 millimeters
• Observe the permissible load-bearing capacity of the wall/ceiling.
• Allow sufficient space to the wall or ceiling.
• Any installation position can be selected.
• Lay the power cable to the installation site, either surface-mounted or flush-mounted.
• Use mounting material suitable for base and of sufficient dimensions.
• Push the cable grommets through correctly, i.e. circular and slightly smaller than the cable, to ensure the degree of protection.
• Select the installation site where foreign objects will not be accidentally drawn in.
• For installation of the external shutter/shutter, see the corresponding installation instructions. Never dismantle them and only install them on a flat surface to ensure proper shutter function.
• For electrical external shutters with plug connections, disconnect the plug and wire the individual cable cores according to the relevant circuit diagram .
