Mounting of ceiling fans

When installing ceiling fans, a few points have to be considered especially for safety reasons. First check the load-bearing capacity of the ceiling. The mounting must be able to support at least 4 times the weight of the fan. In rooms equipped with suspended wooden or plasterboard ceilings, a ceiling fan must never be screwed only to

the plasterboard or woodenceiling for reasons of fall protection, but also to avoid resonance noise (Fig. 3). Screwing into the load-bearing substructure of the ceiling is preferable (Fig. 2). The ceiling mount of the fan with the suspended ceiling is braced against the ﬁxed ceiling, usually made of concrete, with long screws and dowels

(Fig. 1). For grid ceilings, which are common in ofﬁces, we recommend the length-adjustable suspension bracket type SST (Fig. 4 and Fig. 5), which is available in many lengths. This ensures a safe and vibration-free suspension of all our ceiling fans.

When installing a ceiling fan, some minimum distances must be observed for safety reasons, but also to optimize the airﬂow.

Figure 6 shows these distances:

A: Distance to walls: should be at least 40 cm.
B: Distance to slopes: at least 15 cm horizontally.
C: Distance between blades and ceiling: at least 0.2 x fan Ø, except for extra-ﬂat models. From a ceiling height of 3 m, „C“
should be at least 0.3 times, from 5 m 0.6 times and above 0.8 times the ceiling fan Ø. For rooms with low ceilings, always use our extra-ﬂat models!
D: Distance between lower edge of blade and ﬂoor: at least 2.3 m (mandatory in commercial and public areas according
to EN 60335-2-80, recommended in private areas).

Mounting on roof and ceiling slopes

From a room height of approx. 2.7 m or when mounting on roofs or sloping ceilings, we recommend using a longer ceiling rod. A ceiling fan always hangs vertically. Depending on the model, the suspension of our ceiling fans compensates for a tilt angle of the ceiling (Fig. 7, A).

The maximum possible pitch per model can be found on pages 126 - 127. For higher roof pitches, an on-site auxiliary construction in the form of a wedge made of wood or metal (B) is used, which ultimately enables the fan to be mounted on a horizontal surface.

To prevent the blade of the ceiling fan from hitting the pitch of the roof, a longer downrod is required, which can easily be shortened by sawing it off to any intermediate size.

The minimum distance (Fig. 6, dimension C) depending on the angle of the roof or ceiling slope is shown in the following table:

On pages 126 - 127 you will ﬁnd all total distances per model as supplied, as well as with the longer ceiling rods available as accessories. The rods also include a cable extension with patent plugs for easy electrical connection.
