1.8 General risk matrix
Operation
The safety regulations in effect at the operator’s location are mandatory and are
to be observed at all times. During operation, parts of the body or objects must
never be brought within the reach of the fan. Before making an intervention, the
process must be stopped i.e. all mechanical movement is to be stopped and it is
to be ensured that no self-acting motion can occur.
Missing protective equipment
If the fan is equipped with safety equipment, this equipment must neither be
modified nor removed. Further protective devices of a suitable construction are to
be mounted by the operator and are subject to his control.
Disregard of safety precautions
Please implement all safety measures, in order that the fan, together with its
associated equipment, works properly and so that any danger to persons,
materials and products can be excluded.
Decommissioning
In the case of damage or malfunction of protective equipment, the fan is not to be
used any more. It may only be put into operation again when the protective
equipment is full functional again.
Electric power
When any work is done on the fan, the electric drive is to be isolated from the
electrical supply and it is to be made sure that it cannot be reconnected. The
main power switch has to be secured against operation by third parties using a
lockable device (e.g. padlock) by the persons working on the fan. The full
disconnection of the motor is only permissible in case of complete
removal!
The safety regulations for work on electrical equipment in effect at the place of
operation must be observed at all times and be available at the place of
operation.
Electrostatic charge
Because of media flowing in the plastic components, electrostatic charges can
build up. These are harmless for persons who do not respond to electrical
impulses in the body.
Unsuitable materials
Through the use of inappropriate materials, the fan and/or parts of it can be
damaged or become non-operable. 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 are in contact with dangerous
media.
Work on the fan or the carrying out of maintenance work is not allowed during
operation. Before carrying out any work, the system has to be freed from any
dangerous media and, when required, to be neutralised 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, built and tested to EC guidelines 2006/42/EC.
In addition to those EU guidelines and EN standards which have the status of a Swiss norm, Swiss safety
and accident-prevention regulations have also been taken into account.
An EU Declaration of Conformity in terms of the EC 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 operating conditions
The disregard of these stipulations constitutes negligence.
The fan is not suitable fort he 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 trough the fan is 3 meters per second.
The standard motors are designed for normal operating conditions (ambient temperature. +40°C,
location under 1000 m above sea level, air pressure up to 1050 hPa). In the case of 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.

2.2 Correct installation of ATEX fan
The fan must be installed properly to guarantee trouble-free operation. To document proper installation, you
will find a form on the last pages of this operating manual. The fitter must confirm the proper installation item
for item on this form.
The signed form must be kept by the safety officer or operating company.
COLASIT also offers a comprehensive installation service for fans.
3 Shipping, unpacking, inspection
The fan is completely assembled and can be delivered in a closed foil wrapping.
Please make sure the delivery corresponds to the shipping documents.
Please examine the packaging for external damage and report damages
immediately to the transport company, the supervisor and the manufacturer.
Please take caution when moving the fan. Plastics are sensitive to impact and knocks, especially in
the temperature range under +5°C.
When the foil is removed, the intake and delivery connections are open and
unprotected against the intrusion of foreign objects. Therefore, please do not
remove the protective foil until shortly before definitive installation.
Storage
If the fans are not put into operation immediately, store them in a clean dry place
where they are protected from impacts, vibarations, and temperature fluctuations
and where the air humidity is under 90%.
If these storage conditions are not available, switch the fan 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
The fan is to be installed at a location provided and prepared by the customer and has to be secured and
connected in such a way that any possible vibration occurring can be absorbed by the vibration absorbers
provided by COLASIT.
If no ducting is foreseen on the intake side, the intake connection should be protected by a sturdy protective
grating according to IP 20 (12 mm 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 smaller mesh must be
fitted. If the fan is used in a closed system where the possibility of sucking in foreign bodies is excluded, no
protective grating must be fitted.
Connecting ducting on the delivery side must be mounted in such a way that no foreign objects, rainwater or
condensate can run back into the fan. To ensure this, please use the COLASIT condensate drain unit.
Because of the possibility of noise exposure we recommend that the fan should not be installed in the
immediate vicinity of workplaces.
5 Commissioning, initial start-up, test run
The fan should only be put into operation after inspection and approval by the
safety inspector has taken place.
5.1 Inspection of the installation and settings

5.2 Drive
The fan is driven by an electrical motor which is connected either directly to the impeller shaft.
Data on the electrical connection of the motor are indicated on the motor’s data plate or in the motor
manufacturer’s data sheet.
When speed is controlled by means of a frequency converter, the maximum rotational speed is limited by
COLASIT to the value indicated on the manufacturer’s plate.
If the frequency converter is not provided by COLASIT, the operator is
responsible for the observance of the maximum rotational speed limit. In this
case, COLASIT does not assume any liability for damage that can be attributed
to exceeding the maximum rotational speed.
5.3 Electrical installations, EMERGENCY - STOP
The electrical installations may only be carried out by an authorised electrician in accordance with the
regulations valid at the site at which the fan is installed.
For the interruption of the power supply, an EMERGENCY-STOP switch is to be provided. It is advisable
that this switch be mounted in the vicinity of the emergency exit.
Please request confirmation from the in-house electrician that the electrical installations were carried out and
tested in accordance with regulations, that all functions have been tested (or simulated) and that the
rotational direction is correct.
Caution
Do not turn power on or off without prior warning to persons in the area where the
fan is operating. Switching operations must be co-ordinated with other functions
in the working area of the fan.
6 Operation
6.1 Safety regulations
The fan is to be operated according to this manual. In doing so, you will avoid

Description of appliance or protective system:
The radial fans CCV 75 ATEX extract room air or process exhaust air. They are directly driven by electric
motors.
Special conditions: If the fans are operated within explosive atmospheres
in Zone 1 or 2, they may only be driven by motors
for which an appropriate approval (EC type test
certificate) has already been issued.
Temperature Class T4: If the site of installation is Zone 1/2, an
explosion proof motor with temperature class T4 must be fitted.
If an explosion proof motor with temperature class T3 is used,
temperature class 3 shall apply to the entire fan.
Ambient temperature: T -20 - 40°C
Maximum temperature of intake medium: 60°C
The minimum flow velocity through the fan must be
minimum 3m/s.
All service and repair work must be carried out by trained service
personnel.
Additional information: The radial fans of Equipment Category 3 may only be
used to extract gases where the frequency of occurrence
of combustible or explosive atmospheres is equivalent to
Ex-Zone 2.
Basic safety and health requirements:
Fulfilled by standards.
