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 neutralized and secured in such a
way that an inflow of dangerous media is prevented.

1.9 EU 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/EC on machines will be issued
along with the fan.
1.10 Restrictions when commissioning
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 out and until the operating manual has been read completely before
commissioning.
We stipulate that the fan may only be put into operation when the safety inspector
has given his approval. He is obliged to record this approval in a protocol.
The disregard of these stipulations constitutes negligence.
1.11 General operation conditions
The permissible operating conditions are indicated on the manufacturer‘s plate.
The fan is not suitable for the transport of solids in the air flow. This operating
mode will lead to the 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 the destruction of the fan.
The minimum air speed through the fan is 3 meters per second.
If exhaust air with a temperature > 5°C flows through the fan, it can be used up to an ambient temperature of
-20°C.
The standard motors are designed for normal operating conditions (ambient temperature -20 to +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 Explosion protection
COLASIT plastic fans are suitable for the conveyance of gases in Zone 1 or 2 (Equipment Category 2 or 3)
depending on the model. COLASIT plastic fans are not suitable for the conveyance of gases in Zone 0
(Equipment Category 1).
The zone classification of the conveyed medium and the site of installation must be made known by the fan
operator so that COLASIT can take the necessary measures to prevent the risk of ignition.
The explosion-proof COLASIT fans are not suitable for the conveyance of
explosive dusts
No modifications may be made to ATEX-certified fans. All work on the fan may
only be carried out by ATEX-trained skilled personnel.
Otherwise the ATEX Certificate will lose its validity.

On ATEX certified fans, the external grounding terminal of the motor and fan
must be connected to a potential equalization system.
Motors with protection type "e" are standard for using in the explosion-proof design of our fans. The
standard version of the motors used complies with temperature class T3 (maximum surface temperature
200ºC). As special-purpose design, motors with protection type "d" or motors with temperature class T4
(maximum surface temperature 135°C) are also available.
The user must define a suitable temperature class for his application that does
not reach the ignition temperature of his conveyed medium.
Please also observe the specifications in the operating instructions of the motor
manufacturer.
The thermal motor protection must be connected in compliance with the
manufacturer's specifications (operating instructions).
If a frequency converter is fitted, we recommend using pressure-proof enclosed
motors. In addition, a certified PTC resistor releasing device must be fitted.
The following specifications must be included on the motor rating plate: min and
max frequencies, min and max speeds, min and max torque or output, limit
temperature PTC and PTC release time.
2.1 Fan Ex marking

3 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.
4 Installation, configuration
Before installation, check whether all the locking screws (including the motor
screws) 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 (12mm mesh) to be provided by the customer. If small particles can be sucked in which could cause
damage to the fan, a protective grating with a correspondingly small mesh must be fitted.
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.

The casing with its thermoplastic rear panel is screwed onto the support base and can be easily dismantled
for inspection or cleaning purposes.
The fans are available in 2 standard designs
