INSTRUCTIONS MANUAL
Revision 8.0

FOREWORD

THE PRESENT INSTRUCTION MANUAL IS RELEVANT TO THE ASSEMBLED FAN, EQUIPPED WITH AN ELECTRIC MOTOR (IF INCLUDED IN THE  PURCHASE AGREEMENT), SUITABLE TO BE INSTALLED IN AN EXPLOSION DANGER AREA (ATEX) FOR WHAT CONCERNS THE SPECIFIC INSTRUCTIONS FOR THE ELECTRIC MOTOR, REFERENCE SHOULD BE MADE TO THE RELEVANT MANUAL RELEASED BY THE  MANUFACTURER  OF THE MOTOR, WHICH IS ENCLOSED IN THE INSTRUCTION MANUAL

READ THIS MANUAL CAREFULLY BEFORE MACHINE INSTALLATION. AN EXPLOSIVE ATMOSPHERE IS A SERIOUS DANGER TO THE HEALTH OF THE OPERATORS AND THEREFORE ALL POSSIBLE PREVENTIVE  MEASURES MUST BE CARRIED OUT

THE PRESENT MANUAL REFERS TO TWO CATEGORIES OF FANS FOR ATEX:
CATEGORY 2 AND CATEGORY 3. THE TWO CATEGORIES, IN TURN, DIVERSIFY INTO TWO TYPES OF FLUID: GAS (G) OR GAS+DUST (GD).
THESE DATA CAN BE READ BOTH ON THE PLATE APPLIED ONTO THE FAN AND IN THE COMPLIANCE STATEMENT INCLUDED WITH THE  MOTOR, THEY MARK THEIR SPECIFIC CHARACTERISTICS. THE FOLLOWING TABLE DESCRIBES THE CORRESPONDENCE BETWEEN CATEGORY/CLASS AND CLASSIFIED ARE

2

| G (gas)| area 1-2| Atex area, with the occasional presence of gas.
GD (gas- DUST)| area 21-22| Atex area, with the occasional presence of gas dust.

3

| G (gas)| area 2| Atex area, gas is rarely present.
GD (gas- DUST)| area 22| Atex area, gas-dust rarely present.

CATEGORY 2 IS THEREFORE BUILT IN SUCH A WAY AS NOT TO TRIGGER THE AREAS IN WHICH THE ATEX EXPLOSIVE ATMOSPHERE IS OCCASIONALLY POSSIBLE.
CATEGORY 3 INSTEAD IS BUILT IN SUCH A WAY AS NOT TO TRIGGER THE AREAS IN THE ATEX EXPLOSIVE ATMOSPHERE THAT ARE NOT  NORMALLY PRESENT, BUT IT CAN RARELY OCCUR (USUALLY IN CASE OF DEFECTS OR FAULTS

VENPLAST FANS DO NOT BELONG TO CATEGORY 1, WHICH MEANS THAT THEY ARE NOT SUITABLE TO OPERATE IN ATEX 0-20 AREAS, WHERE  ATEX IS OFTEN PRESENT OR PRESENT FOR LONG PERIODS OF TIME.

THE “T” TEMPERATURE CLASS IDENTIFIES THE MAXIMUM TEMPERATURE OF THE EXPOSED SURFACES OF THE FAN. THE TABLE HERE BELOW  SHOWS ALL THE TEMPERATURE CLASSES ARE ADMITTED BY THE ATEX NORMS

THE CLASS WITH A HIGHER NUMBER IS ADEQUATE ALSO FOR THE CLASSES WITH A LOWER NUMBER.
FOR EXAMPLE TEMPERATURE CLASS T6 IS SUITABLE ALSO FOR T5-T4-T3-T2-T1 TEMPERATURE CLASS T4 IS SUITABLE ALSO FOR T3-T2-T1, NOT FOR T5 and T6
BEFORE INSTALLATION OF THE MOTOR IT IS IMPORTANT FOR THE USER TO CAREFULLY CHECK THE FAN CATEGORY, TYPE OF FLUID, AND TEMPERATURE CLASS

MARKING

ON THE FAN A CE ATEX MARKING PLATE IS APPLIED, WHICH IDENTIFIES EXACTLY THE TYPE OF EQUIPMENT

ORGANIZATIONAL MEASURES

The organizational measures are foreseen by the employer (user), in the prevention field and the
protection against exposures foresee:

• elaboration of written instructions, if foreseen by the document regarding the protection against explosions,
• training the workers regarding protection from explosions,
• sufficient qualification of the operators,
• application of a system of authorizations for dangerous activities, whereby foreseen by the document regarding protection against explosions,
• interventions of maintenance,
• checks, and surveillance,
• where necessary signals to indicate potentially explosive areas.

The organizational measures adopted must be indicated in the document regarding the protection against explosions.
Warning: the expectable duration of the product, for safety regarding protection against explosions, is five years. Once this period has been exceeded the safety functions which protect against explosions are no longer guaranteed. The user must therefore substitute the product or make sure it is completely revisioned by the company of manufacture and other specialized company for the release of a new declaration of conformity.

Warning: This manual describes the block fan + motor that comes with it (electro blowing fan) Should only the fan be supplied, without the electric motor, the parts of the manual concerning the electrical parts must not be taken into consideration.
In this case, the responsibility of the choice of the electric motor is up to the buyer, who will have to take care of choosing a motor that is compatible with the fan certification.

WARRANTY

The manufacturer guarantees its products for a period of (twelve) months from the date of purchase. This warranty covers only free reparation or substitution of those parts that after careful examination by the company of manufacture result to be faulty (this excludes electrical parts and the tools). The warranty, with the exclusion of any responsibility for direct or indirect damage, is limited only to faults in the material and is no longer valid should the parts returned result as having been disassembled, tampered with, or repaired outside the factory.
The warranty does not cover damage caused by carelessness, negligence, bad or improper use of the equipment, and incorrect use by the operator.
The warranty is no longer valid and VENPLAST s.r.l. will not answer for damages should the safety devices that come with the equipment have been removed. In addition, the warranty is no longer valid should nonoriginal spare parts be used.
The equipment returned, even if under warranty, must be delivered carriage paid. See also the chapter “General sales conditions” on the last page.

PRESERVATION OF THE MANUAL

This manual must be kept in a safe place by the head of the department’s office.
The employer must give this instructions manual (original or copy) to the workers in order to adequately inform them of correct machine use.

GENERAL INFORMATION

SITUATIONS OF DANGER
It is strictly forbidden to introduce limbs or the whole body inside the parts in movement
Is strictly forbidden to remove, take away, modify and/or alter the safeties.
LIMITATIONS OF USE

The fan has been designed and manufactured to direct air with the presence of corrosive gas/vapors at a temperature between -15C° and +70C°. The limits of concentration of
corrosive substances that can be conveyed are shown below. Any other use is forbidden.
To find out about the compatibility of the fan with the fluids to be conveyed, observe the table that follows, which is to be intended as an example, and it is not exhaustive in all the possible combinations.

FAN DESCRIPTION

AIM| Moves air with the presence of corrosive gas/vapors that can be characterized by corrosive concentrations.
---|---
WORK CYCLE| 1  Aspiration
Through the volute suction mouth, the air is aspirated through a tube or directly from the environment in which it is installed.
2 Expulsion
The air can be directed into apposite pipes or into the outside air from the permanent mouth of the volute.
MANUFACTURE| 1 Volute
Plastic structure as described in the catalog, to direct the air with the presence of gas/vapors moved by the impeller.
2 Impeller
Rotor with vanes is put into rotation by an electric motor.
3 Support structure
Supports the parts which are used directly to convey air in the presence of gas/vapors.
4 Motorization
The mechanical system gives the rotary mode to the impeller (in the model with the suffix “T” there is a transmission belt-pulley).
OPERATIONS| Direct the air with the presence of gas/vapors
__ The fan, as the effect of the rotation of the impeller, creates a depression that aspirates the fluid into the volute and pushes it into the exit channel.

DESCRIPTION OF THE MOST COMMON ACCESSORIES
The fan has the following accessories that are available on request:

•  Anti-vibration coupling: absorb the vibrations that can be transmitted in the tubes of the aspiration system.
• Anti-vibration supports: absorb the vibrations that can be transmitted to the support of the appliance.
• Butterfly valve: regulates the capacity of air in the tubes.
• Tubes: to connect the fan to the system.
• Condensation discharge: unloads the condensation that forms inside the volute.
• Curves and reductions: make up the junctions between the lengths of the pipes

WARNING

ENVIRONMENT AND FLUID SUCKED TEMPERATURE

The fan is suitable to work in an external atmosphere, or fluid sucked, with a maximum temperature field of –20 + 60°C

THE WHOLE MOTOR-FAN

The whole motor fan consists of two separate parts that are united together, but which have two separate certification procedures (electric and nonelectric).
Therefore the electric motor could have a marking plate showing the maximum superficial temperature (T1:T6) which is different (more preventive) from the fan temperature.  There are cases in which the motor has a category that is superior to the one of the fan.
The user must therefore know that the reference plate of the whole body must always be the one on the fan. The rule is, for the appliance as a whole, the lowest category establishes the category of the whole body.
For example fan cat.3 + motor cat. 2 = the whole body category

ASSESSMENTS IMPOSED BY LAW
The electrical systems installed in places with the danger of explosion are subject to assessment before the first installation, carried out by regional ARPA (regional institution for the environment protection, ndt), and subsequent checks are to be carried out every two years. Assessments are charge of the end user

MAINTENANCE

Periodical maintenance of the fan is extremely important to maintain the safety functions of the appliance constant in time. The user must therefore adhere to the maintenance  table described in the opposite chapter

INSPECTION DOORS

Some fan models come with an internal inspection door. It is recommended to open it only when the machine is stopped

VIBRATIONS

The model “2GD” (see marking) is suitable for installation in an environment with combustible dust (for example wood), therefore an alarm sensor is necessary to intervene when the permitted maximum vibration limit is exceeded, in order to avoid dust caused by anomalous friction.
Such a device must be connected to the stop sequence of the motor to stop the machine in case of an anomaly (only for the model “dust”). The device must be installed by the purchaser. The model category 3GD on the contrary does not need any vibration sensor

SPEED REGULATION WITH INVERTER

The fan does not come with speed regulation with the operation (inverter). Therefore it is not possible to exceed the motor’s nominal speed or to operate at a low speed because the motor would overheat.
Should the buyer need a speed regulation, he must contact the manufacturer to install the necessary additional protection measures ( Thermo protector on the motor, speed limiting device, etc…

CLASSIFICATION OF THE AREA AROUND THE FAN

The fan can not guarantee perfect gas tightness, therefore the fan is a potential source of Atex emission according to CEI 31-30 regulations. (Classification of the areas with  danger of explosion title XI° Legislative decree 81/08

FOREIGN MATTERS INPUT (only for cat . 2)

The input of foreign matters into the fan can damage it, it is, therefore, necessary for the user to arrange suitable mesh stopping systems to stop foreign matters larger than 3 mm

SAFETY DEVICES

The fan does not have active safety functions since it must be integrated into a system that controls feeding and control.
The buyer must therefore evaluate the risk of the appliance, on the whole, and adopt the necessary measures.
Uncovered moving parts (impeller) represent the main risk, which must be protected by protections in the areas of air entry and exit. These protections are usually represented by the air channels, in the installation phase.

ENVIRONMENTAL CONDITIONS ALLOWED
The fan can be installed in the work environment with a temperature between -15C° and +70C° and not exceeding 1000 meters above sea level (with the exception of particular
agreements with the manufacturer

WORKPLACE REQUIREMENTS

SUPPORT SURFACE:
Dimensioned so that it can support the weight as declared in the catalog as well as loads that are already present and must be sufficiently stable to avoid possible falls.
NECESSARY CONNECTIONS:
Electric
Aeraulic

TRANSPORT

TRANSPORT DATA

The fan must be transported inside a box or a pallet.

DANGERS

The fan must be handled as it has been delivered, it is heavy and has sharp and protruding parts which are dangerous, and therefore necessary individual items of protection must be used.
The equipment must be cleaned carefully before handling, in order to avoid debris from work processing falling unexpectedly during lifting operations.

PRECAUTIONS TO BE ADOPTED
WARNING: take care at all times
WARNING: wear suitable accident prevention clothing.
WARNING: follow the procedures of this manual extremely carefully.
WARNING: make sure the lifting parts are adequately oversized for the weight needing lifting
**** Do not for any reason go near the equipment if it has not touched the ground and if the lifting measures are not active

HOW TO TRANSPORT THE PACKAGING
WARNING: for safety reasons do not handle weights exceeding 25 kg by hand. If so carry out lifting operations together with other operators or use appropriate lifting devices.

• Lift the packaging and place it on the support surface inside the means of transport.
• Transport to the place of installation.
• Unload the packaging from the means of transport and place it near the place of installation

UNPACKAGING

• Place the packaging onto a stable surface
• Open the packaging
• Extract the fan

HOW TO TRANSPORT THE FAN

• Manual handling is allowed up to 25 kg
• Over 25 Kg more operators are required or use appropriate lifting measures

INSTALLATION

HOW TO INSTALL THE FAN
PRECAUTIONS TO BE ADOPTED
WARNING: follow the procedures in this manual extremely carefully
WARNING: use suitable accident prevention clothing.
WARNING: for anything regarding the electric part and for connection contact a qualified electrician
WARNING: Before carrying out a connection to the electricity supply make sure it is impossible to access the impeller with one’s limbs. If this is not so segregate the appliance using the protection grid and connect it to the return and aspiration tubes.

1. Before carrying out machine installation, the area must be made safe from the danger of explosions. This can be obtained by eliminating the sources of emission of  inflammable substances and combustible dust present in or around the area
2. All those openings from which an inflammable substance can be emitted in the form of gas, vapor, fog, and combustible dust are sources of emission.
3. Make sure possible sources of a start-up can not spread through the aspiration channels.
4. The electrical connections to the motor must be explosion-proof in category 2GD, if this is not so the protection results be void.
5. Carry out the earth electrical connection in the apposite clamp supplied by the manufacturer.

The start-up source is the physical element that, bringing sufficient energy to an explosive atmosphere, provokes an explosion.
Elimination of the trigger sources is of prior importance to prevent explosions.
Foreign bodies that may be aspirated into the fan can be a trigger source or can damage the fan itself and impairs the safety functions.
The installer, or the user, must therefore arrange a suitable system in the channel to stop foreign bodies.
Law EN14986:2007 foresees that a device to stop solid bodies is created with a level of protection not inferior to IP20.

A list of possible trigger sources follows:

• FREE FLAMES (oxyhydrogen welding)
• ELECTRIC MATERIAL
• SPARKS FROM MECHANICAL /ABRASION (grinding, cutting, abrasion, welding)
• HOT SURFACES (welding)
• ELECTROSTATIC DISCHARGE (insulating material)
• EXOTHERMIC REACTIONS (chemical reactions)
• SHOCK WAVES
• IONOGENIC AND NON-IONOGENIC RADIATIONS
• HIGH-POWER ELECTROMAGNETIC WAVES

BEHAVIOUR TO BE ADOPTED

1. Transport and unpack as described beforehand
2. Use the fan itself to individuate the position of the fixing screws.
3. Make the slots.
4. Position the fan so that the slots of the support structure correspond with those of the surface of the installation.
5. Fix the structure to the surface using pressure stoppers or bolts depending on whether the surface of installation is iron or cement. If present, use the antivibration supports.
6. Connect the suction and delivery pipes, taking care to avoid applying thrust forces onto the fan itself, in such a way as to avoid structural deformations which may give origin to frictions between the revolving unit and the fixed parts.
7. Isolate the fan using appropriate fixed protections in order to make it inaccessible.
8. If present, apply the condensation discharge in the low part of the volute to allow the condensation to drain away. Make sure there is a system to collect this condensation.
9. Protect the fan using apposite grids/grates to avoid contact should the dangerous moving parts be accessible.
10. The channels must be in compliance with the ISO norms 5801 and 5802, for correct design and installation devoid of vibrations

CONNECTION TO THE ELECTRICITY SUPPLY

Must be carried out when the fan has been positioned. A qualified electrician must follow the indications of the electrical technical documentation attached to the terminal box of the electric motor.
It is recommended that ground electrical connection be carried out in the relevant clamp.
The electrical connection must be carried out in compliance with norm CEI EN 6024-1.
It is recommended that the motor is protected from short circuits, overload, and lack of phase.
Electrical cabling must be compatible with the equipment category (2 or 3). Cabling carried out wrongly may render null and void all the Atex protection of the electric fan. In particular, it is recommended that the electric performance in category 2 be carried out ExD explosion proof, and  complete with resin-bonded locking joints

CALIBRATION

The fan does not require initial calibration.

MAINTENANCE

WARNING: Maintenance must be carried out only by specialized technical personnel, who know the machine and the risks connected to it.
WARNING: Before carrying out maintenance attach signs “maintenance in progress” in well visible and in various places.
WARNING: wear protective gloves suitable for contact with the nature of the fluid with the possible presence of gas/corrosive/ harmful or toxic vapors and their deposits.
WARNING: wear accident prevention clothing as foreseen by the employer
WARNING: follow the indications in this manual.
WARNING: to see more clearly inside the volute use a portable auxiliary light with protection.
WARNING: before intervening on the fan make sure the electricity supply is cut off and that measures of prevention against undesired start-up have been taken.
WARNING: The impeller presents inertia, therefore after the fan shut down it continues to rotate for some time depending on its size. Wait for a complete shutdown before access. Consider also the possibility that the impeller can start to rotate caused of the currents of air inside the pipes.

MAINTENANCE TABLE

Replacement of the bearing of the electric motor and of the conveying support, if present.| every 30.000 hours

TOOLS USED IN EXPLOSIVE ATMOSPHERE

There are two types of tools:
a) tools that can cause only single sparks when used (for example screwdrivers, spanners, percussion screwdrivers);
b) tools that generate a series of sparks when used to saw or grind.
In areas 0 and 20 tools that produce sparks are not allowed.
In areas 1 and 2 only stainless steel tools in conformity to a,) are allowed. Tools that conform to b) are allowed only if it can be assured that dangerous explosive atmospheres are not present in the workplace.
However, the use of any kind of stainless steel tool is strictly forbidden in area 1 if risk of explosion due to the presence of substances belonging to group II c (in accordance to  EN 50014) (acetylene, carbon disulfide, hydrogen), and hydrogen sulfide, ethylene oxide, carbon monoxide, unless the dangerous explosive atmosphere is not present on the workplace when using these tools.
The use of tools in areas 1, 2, 21, and 22 should be subject to a “work permit” (see the last page of the manual)

DO NOT USE TOOLS THAT MAKE SPARKS INSIDE AREAS WITH THE DANGER OF EXPLOSION
DO NOT USE FREE FLAMES, DO NOT SMOKEFor work that requires the production of sparks (e.g., welding, fire grinding) the following measures of protection must be adopted (as in the picture) and if necessary activate a  service of fire prevention surveillance

REPARATION

TYPE OF SPECIALIZATION REQUIRED

Maintenance, reparation, and cleaning operations must be carried out by skilled and qualified personnel who know the product. We recommend reparations be carried out only by the company of manufacture or by a company that specialized in fans.

PREVENTIVE MEASURES
WARNING: Before carrying out reparations on-site attach signs “REPARATION IN  PROGRESS” so that they are visible and in different places.
WARNING: wear accident prevention clothing.

4. Assemble the volute as described in the relative chapter

WARNING:
The fans which have been certified for dust (GD) must be kept clean from exceeding layers of dust, both internally and externally.
The inflammable layer of dust is an obstacle to the heat dissipation of the motor, which may become overheated and set to fire the layer above it.
The internal layer instead, may obstacle the mobile parts in their interconnected motion, thus triggering frictions.
Follow the cleaning procedures table provided, as laid out by Venplast
