1 Operating instruction information
Scope
These operating instructions provide qualified personnel with all essential safety
instructions, information, and guidance for working with CMVpro 125-400 ATEX
type centrifugal fans.
All phases of a centrifugal fan from transport, mounting, and placement in ser-
vice to repairs and disposal are covered.
Careful reading of and compliance with these operating instructions will help to
avoid injuries as well as environmental and material damage, ensure operational
safety and reliability of the centrifugal fan, and minimize downtime.
Storage location
The operating instructions and associated documents are to be stored near the
centrifugal fan such that they are easily accessible to qualified personnel at all
times.
The operating instructions and associated documents are also to be provided in
electronic form upon delivery of the fan. This gives the operator the ability to
print new operating instructions in the event that they go missing or to replace il-
legible or missing pages.
Design notes
For the sake of simplification, in these operating instructions,
• the company Colasit AG is referred to as the “manufacturer,”
• the CMVpro 125-400 ATEX centrifugal fan is referred to as the “fan,”
• “frequency converter” is abbreviated as “FC,”
• chapter and page number references appear as follows: _ Chap. 1 [}7]
The images in these operating instructions are for illustrative purposes and
could differ from the actual execution.
In the interest of our customers, we reserve the right to make changes as a re-
sult of technical developments.
Translation note
The German language version of this document is the original set of operating
instructions.
Inquiries
If possible, clarify any ambiguities in a given language version with the aid of the
original operating instructions. Ambiguities regarding the operating instructions
are to immediately be clarified with the manufacturer. Placement in service of or
other work on the fan is only permitted after successful clarification.
1.1 Further applicable documents
In addition to these operating instructions, the following documents and guid-
ance shall be available as associated documents for working on the fan:

1 | Operating instruction information
8 / 88 Operating instructions CMVpro 125-400 ATEX | Version 1-en
• Technical data sheet for the fan with complete technical data, including ap-
plication limitations.
• Order confirmation or the specification sheet for the conveyed medium with
information on the (limited) resistance of the fan to certain chemical sub-
stances. See also “Permissible conveyed media” _ Chap. 2.2.1 [}9].
The order confirmation also provides details regarding the full scope of delivery.
• Operating instructions for the electric motor.
• ATEX declaration of conformity for ATEX components: partly contained in
separate operating instructions.
• Operating instructions for devices or equipment that were installed or in-
cluded
(e.g. FC or isolation switch).
Additional document
• Manufacturer’s electromagnetic compatibility guideline, if the fan is intended
for operation with a frequency converter (FC).
1.2 Copyright

Operating instructions CMVpro 125-400 ATEX | Version 1-en 9 / 88
2 Additional safety instructions
This chapter contains information relevant to safety and additional as well as
more in-depth safety instructions for operators and technical specialists.
Additional safety instructions
Depending on the execution of the fan, associated documents can contain addi-
tional operating instructions with important safety instructions.
2.1 Use and storage of the operating instructions
• Before beginning mounting procedures or working on the fan, read these
operating instructions carefully and completely.
• After use, always return the operating instructions to the marked storage lo-
cation near the fan.
2.2 Intended application of the fan
The fan is intended for conveying gaseous media in potentially explosive atmos-
pheres and is designed and manufactured in accordance with the state of the art
and the recognized technical safety regulations.
Nevertheless, the fan may pose a danger to life and limb of personnel or third
parties as well as material damage. Special care is therefore to be taken to en-
sure that the fan is in technically sound condition and that it is used as intended.
2.2.1 Intended use
The fan is intended exclusively for the application specified on the nameplate
and for installation in a complete system _ Chap. 4.2 [}25]. The fan may only
be transported, mounted, and operated by trained qualified personnel with ap-
propriate ATEX training/qualification _ Chap. 2.3 [}14].
Operating guidelines for potentially explosive atmospheres
The fan
• is suitable for conveyance of gases in zone 1 or 2 (equipment category 2
and 3), depending on the execution.
See fan nameplate _ Chap. 5.2 [}27] and ATEX Declaration of Conformity for
this _ Chap. 15 [}80].
Permissible conveyed media
In general, conveyance of dust-free air is permissible within the parameters
specified in the technical data sheet.
Conveyance of corrosive, hazardous, explosive, gaseous media is restricted as
follows:
1. The following apply to a conveyed medium that is specified in the fan's tech-
nical data sheet:
• The fan is suitable exclusively for conveyance of the specified medium.
• The service life of the fan could be limited if there is a corresponding
note in the order confirmation or the specification sheet.

2 | Additional safety instructions
10 / 88 Operating instructions CMVpro 125-400 ATEX | Version 1-en
2. The following apply to a conveyed medium that is specified as “undefined”
in the fan's technical data sheet:
• The fan is suitable for conveyance of corrosive, hazardous, explosive,
gaseous media that fall under the explosion protection marking of the
fan (explosion group, temperature class) and to which the plastics of
the fan and the sleeves are resistant.
• For independent assessment, the operator is to consult the pertinent
available resistance lists for plastics. The SIMCHEM guide is found on
the manufacturer's website (www.colasit.ch).
The impeller, inlet cover, and housing of the fan are marked with an abbreviation
for material identification (e.g. PPs-el for anti-static, electrically conductive plas-
tic made of polypropylene).
• The order confirmation or the additional specification sheet contains fur-
ther information and notes regarding a potential reduction in service life
of the fan.
3. The following apply if, according to the operator’s information, the conveyed
medium contains several chemical substances:
• The named importer or the manufacturer confirms the resistance of the
fan to these chemical substances in the order confirmation or the speci-
fication sheet, which is an associated document.
• The service life of the fan can be limited if there is a corresponding note
in the order confirmation or the specification sheet.
Permissible environmental conditions
1. The permissible operating and ambient temperature ranges are indicated on
the fan nameplate.
The minimum permissible operating temperature for the plastic parts of the
fan is -20 °C.
2. The following applies if this information is missing from the nameplate:
• Permissible ambient temperature range of the electric motor: See
nameplate of the electric motor or the operating instructions/declaration
of conformity of the motor manufacturer.
3. At operating temperatures below 4 °C, it is to be ensured by means of a
constant minimum flow rate that
• no condensate freezes in the fan or ductwork.
• no pieces of ice from the ductwork get into the fan.
Procedure for process changes
• The operator is to ensure upon a process change that
• the fan can withstand the zone or parameters changed or the new con-
veyed medium,
• the operating conditions according to the technical data sheet and
nameplate plate are adhered to.
