1.8 General risk matrix
Operation
The safety regulations prevailing at the operator’s location are mandatory and must be
observed at all times. Before making an intervention, the process must be stopped, i.e.
all mechanical movement must be stopped and it must be ensured that no automatic
motion can occur.
Missing safety devices
If the fan is equipped with safety devices, they may neither be modified nor removed.
Further safety devices of suitable design must be fitted by the operator and are subject
to his control.
Disregard of safety precautions
Please implement all safety measures so that the fan, together with its associated
equipment, can operate properly and any danger to persons, materials and products can
be excluded.
Putting the fan out of operation
In the case of damage to or failure of safety devices, the fan must be stopped and put
out of operation. It may only be put into operation again when the safety devices are fully
functional again.
Electricity
When any work is carried out on the fan, the electric motor must be deenergised and
secured to prevent it from switching on. The main power switch must be secured against
operation by third parties using a lockable device (e.g. padlock) by the persons working
on the fan. Full disconnection of the motor is only permissible in case of complete
removal!
The safety regulations for work on electrical equipment prevailing at the place of
operation must be observed at all times and be available for reference at the place of
operation.
Electrostatic charge
Media flowing through the plastic components may cause the buildup of electrostatic
charge. These are harmless to persons who do not react to electrical impulses in the
body.
Unsuitable materials
Through the use of inappropriate materials, the fan and/or parts may be damaged or
become non-functional. Please always use original spare parts and contact the
manufacturer in any case of doubt.
Dangerous media
Depending on the mode of operation, fan parts may come in contact with dangerous
media.
Work on the fan or carrying out maintenance work is not allowed during operation.
Before carrying out any work, any dangerous media must be removed from the system
and, when required, must be neutralised and secured in such a way that an inflow of
dangerous media is prevented.

1.9 EC conformity of the COLASIT fan
The fan was designed, built and tested to Directive 2006/42/EC.
In addition to this EU Directive and EN standards which have the equivalent status of a Swiss standard,
Swiss safety and accident-prevention regulations have also been taken into account.
An EU Declaration of Conformity in terms of the guidelines 2006/42/EU on machines will be issued along
with the fan.
1.10 Restrictions when putting into operation
We stipulate that putting into operation is prohibited as long as the fan, including all parts
belonging to it or equipment connected to it, has not been installed and checked and until
the operating manual has been read completely before putting into operation.
We stipulate that the fan may only be put into operation when the safety officer has given
his approval. He is obliged to record this approval in a report.
Any disregard of these stipulations constitutes negligence.
1.11 General operating conditions
The permissible operating conditions are specified on the manufacturer‘s rating plate.
The fan is not suitable for the conveyance of solids in the air flow. This operating mode will
lead to destruction of the fan.
The ducts on the intake and delivery sides must always be open. A closed duct will lead to a rise in
temperature, which could cause destruction of the fan.
The minimum air speed through the fan is 5 meters per second.
The maximum air speed may not exceed 30 meters per second through the fan.
The standard motors are designed for normal operating conditions (ambient temperature +40°C, altitude
below 1000 m above sea level, air pressure up to 1050 hPa). In case of any divergence from these
conditions, please contact COLASIT.
Compliance with these operating conditions is the responsibility of the operator.
2 Shipping, unpacking, inspection, storage
The fan is completely assembled and can be delivered in a closed film wrapping.
Please make sure the delivery corresponds to the shipping documents.
Please examine the packaging for external damage and report any damage immediately to
the transport company, the supervisor and the manufacturer.

Please handle the fan with care. During transportation, only apply strain on the steel parts. Plastic is
sensitive to impact and knocks, especially in the temperature range under +5°C.
When the film is removed, the intake and pressure nozzles are open and unprotected
against the intrusion of foreign objects. Therefore, please do not remove the protective film
until shortly before final installation.
Storage
If the fans are not put into operation immediately, store them in a clean dry place where
they are protected from impacts, vibrations, and temperature fluctuations and where the air
humidity is under 90%.
If these storage conditions are not available, switch the fans on at regular intervals to
exclude the risk of condensate forming. Before switching on, unscrew the condensate drain
plugs each time and replace them afterwards.
Store the fan in a dry, weather-protected place and cover with a tarpaulin to protect it from dust and soiling.
If stored for over one year, test whether the fan bearings rotate freely before putting into operation.
3 Installation, design
Before installation, check whether all the locking screws (including the motor screws)
they are tightened properly.
Check the electrical connections if wired at the factory.
Before installation, check that there are no foreign bodies in the coil or in the intake and
pressure connections.
The fan must be installed at a location provided and prepared by the customer and must be secured and
connected in such a way that any possible vibration occurring can be absorbed by the vibration dampers
supplied by COLASIT.
If no ducting is foreseen on the intake side, the intake connection should be protected by a sturdy protective
grating (10mm mesh) to be provided by the customer.
Connection ducting on the pressure side must be routed to prevent the backflow of foreign bodies, rainwater
or condensate into the fan. To ensure this, please use the COLASIT condensate drain nozzles.
Due to the possibility of noise nuisance, we recommend that the fan should not be installed in the immediate
vicinity of workplaces.
4 Commissioning, initial startup, test run
The fan should only be put into operation after inspection and approval by the safety officer.

4.1 Inspection of the installation and settings
Check list:
Prior to commissioning and initial startup, it must be guaranteed that:
the fan is installed vibration-free and mechanically secured,
all components are cleaned both on the inside and the outside and are free from foreign bodies,
all intake and pressure ducts connections are leakproof and elastic,
all rotating parts are protected against unintentional contact,
the electrical connections are installed and their functions tested,
there is a lockable revision switch to which the fan is connected,
the device is functionally tested,
the safety officer has checked the presence of safety devices,
the operating personnel is familiar with the operating manual,
the safety officer has granted his approval for the operation of the system and that
no external persons are present in the vicinity of the system.
If envisaged by process regulations provided by the operator, records of the commissioning work, including
check list, must be kept.
4.2 Drive
The fan is driven by an electric motor which is connected to the impeller shaft either directly or via a V-belt.
The motor electrical specifications are indicated on the motor’s rating plate or in the motor manufacturer’s
data sheet.
When speed is controlled by means of a frequency converter, the maximum speed is limited by COLASIT to
the value indicated on the manufacturer’s rating plate.
If the frequency converter is not supplied by COLASIT, the operator is responsible for
compliance with the maximum speed limitation. In this case, COLASIT will not assume any
liability for damage that may be attributed to exceeding the maximum speed.
In order not to overload the fan mechanically, 60sec. acceleration and braking times must be observed.
Depending on the maximum available starting current of the frequency inverter, a longer acceleration time
may be necessary to avoid an error message.
4.3 Electrical installations
The electrical installations may only be carried out by an authorised electrician in accordance with the
regulations prevailing at the site at which the fan is installed.
To interrupt the power supply, a revision switch must be provided. It is advisable to mount this switch in the
vicinity of the emergency exit.
Please request confirmation from an in-house electrician that the electrical installations were carried out and
tested in accordance with regulations, that all functions were tested (or simulated) and that the rotational
direction is correct.
