M8 Screw: 27 Nm
•
M10 Screw: 53 Nm
•
M12 Screw: 92 Nm
5.5 Tie bars
The Manufacturer markets and provides a specific metal tie bar kit for the ceiling fan, supplied if requested by
the purchaser.
This tie bar kit ensures additional axial stability for the ceiling fan, and keeps it at its height if, due to outside
causes, the machine is stressed anomalously, or the ceiling assembly with just one central pole, does not en-
sure adequate solidity over time.
The installation MUST be completed using the tie bar kit for safety reasons, if the purchaser or installer finds
any of the following, in the actual production situation and installation position of the ceiling fan inside the indus-
trial building involved:
•
The possibility that the ceiling fan may be struck by gusts of wind (e.g. opening of doors or windows),
or that the ceiling fan is installed in buildings that can be opened on the sides.
•
The possibility that the ceiling fan may inadvertently be struck by machines or equipment used by the
purchaser or others, working inside the building in which the fan is installed.
•
The possibility that the ceiling fan may be struck by flying creatures, flying around inside the building in
which it is installed.
•
The industrial building is located in an area defined to be seismic or, in any case, subject to apprecia-
ble sources of vibrations that affect the building.
WARNING: Since the assessment of the need to do the installation with an additional tie bar kit depends
completely on objective conditions related to the property, the type of production activity and mode of the same,
and these conditions cannot be ascribed to the Manufacturer, the Manufacturer does not accept any
responsibility for not using the tie bar kit for installation, while stating that its use is preferable and safer.
Installing the ceiling fan in the presence of winds or draughts that strike the machine on the side, with wind
speeds greater than or equal to 14 m/sec, is expressly forbidden. For wind speeds of between 10 and 14 m/sec,
use of the tie bar kit for installation is obligatory, and the machine is already set up for the same.
In the case of strong side winds that strike the ceiling fan, in addition to wind bracing in the form of the tie bar kit,
it is important that the machine is never stopped, but continues to rotate at minimum revs, in order to balance the
side forces that strike it.
We do not advise using the ceiling fan in dusty settings, such as places in which flour or light, easily volatile
elements are present.
5.6 Noise emissions
The acoustic pressure level of pondered emission A in workplaces does not exceed 70 dB(A).
5.7 Cleaning
The machine can be cleaned using products suitable for cleaning aluminium and steel. Each cleaning operation
deemed necessary, must be done with the power supply to the machine disconnected. Suitable precautions
must be taken to avoid subsequent untimely switch
- ons during the operations, and operators must wait until the
fan has stopped rotating. Aiming pressurised water towards the ceiling fan for cleaning operations is expressly
forbidden, even though the machine is in class IP65.
5.8 Electrical connection
The installation involves the use of a control unit with an output of 1 - 10 V. However, as an
alternative a manual potentiometer can be used, the only difference being that starting and
stopping the machine must be done manually. Each control unit chosen by the client must be CE
certified, or must at least conform to the low voltage and electromagnetic compatibility directives.
Failure to ensure this will render the warranty null and void, due to damage caused to the machine
due to the use of unsuitable material. However, this choice does not affect the installation
procedure described below.
