3 .1 Assembly – Installation
m
The fan can tip over and crush limbs during installation/unpacking .
Observe transport diagram and centre of gravity (see section 2.2 Shipping)!
m Sharp edges can cut you during installation .
Wear protective footwear and gloves.
m The rotating impeller can cause injury to limbs .
The installation must be carried out so that access on the intake side is not possible (e.g. through piping, protection
guard, sufficient height above the ground).
All occupational safety regulations, installation conditions and declarations of performance must be observed for as-
sembly and installation! The smoke exhaust fans must be positioned and installed so that inspection, maintenance and
repair work can be carried out easily and safely.
Installation conditions
VA: Suitable for “vertical installation”, drive axle inclination not permissible.
LB: For “Ventilation mode” -20 °C to +60 °C.
IF: “Outside” fan without insulating layer if it is ensured that rainwater cannot penetrate the smoke exhaust
fan.
BG: Only over heated rooms.
ND: Roof installation only.
3 .2 Roof installation
m The safety instructions specified in section 1 and 2 must be observed!
m Do not stand under suspended loads!
m Appropriate fall protection measures must be taken when working on roofs or building edges .
Lift the flat roof base onto the roof with a suitable crane (note weight information). Place the flat roof base over the
ceiling opening on the raw ceiling of the flat roof. Then align with the roof so that the circumferential adhesive rim is
horizontal. Completely run the roof coating over the adhesive rim of the base and seal with bitumen fibre cement.
Tightly screw the roof base to the raw ceiling of the flat roof through the provided drill holes. Then carry out the ne-
cessary insulation work (insulation, waterproofing, vapour barrier etc.) on-site (see Fig. 7).
Make sure that the accessibility is ensured during installation . If necessary, clad inside of ceiling cut-out/
opening .
