All electric components and different motor types used in ATEX models comply with the necessary security requirements. Other structural modifications have been added to avoid sparks that can be produced by rubbing between static and mobile components or by electrostatic discharges. Do not manipulate or modify none of these elements under any concept.

For all of the applications in general where some type of electronic velocity regulation system is needed by the fan, this should be previously consulted and authorized by VORTICE S.P.A. and comply with the electromagnetic compatibility norm 89/336/CEE. The nonauthorized use of any type of electronic controller with a fan can be very dangerous and make all security devices useless, not fulfilling the ATEX requirements.

For major safety upon carrying out the maintenance of the fan, VORTICE S.P.A. recommends to install a SAFETY STOP/START SWITCH, appropriate to work in explosive atmospheres and agreement with Director ATEX 2014/34/CE with manual disconnection.

IMPORTANT: THIS PARTICULAR FAN MAY NOT BE IN ADEQUATE FOR THE SAFETY EXIGENCIES OF YOUR INSTALLATION. THEREFORE, PLEASE VERIFY THAT THE CHARACTERISTICS SPECIFIED ABOUT THE APPARATUS COMPLY WITH ALL OF THE APPLICATION REQUIREMENTS BEFORE INSTALLING IT. VERIFY THAT GROUP, CATEGORY, AND CLASS TEMPERATURE SPECIFIED IN THE CHARACTERISTIC PLATE AGREES WITH THE REQUIRED ONE FOR THE INSTALLATION

APPLICATIONS

The requirable requirements and characteristics for each fan model are conditioned, in each case, to the norms and regulations of a general, as well as local character to which each particular application may be subject. Thus, in some cases, the selected units of the series may result in not be apt for certain applications, whereby other special characteristics should be added or incorporated. For example, the units destined to be installed in surroundings with fire or explosion risks, should comply with norm ATEX 2014/34/CE and, therefore, be equipped with some of the established protection systems. The units destined to Vortice S.P.A. for emergency services in case of fire should be homologated according to norm UNE EN 12101-3/2002 and comply with the regulation CTE – 305/2011/EU (CPR). Also, other habitual characteristics, such as elevated work temperature, corrosive surroundings, etc. may also require some special variant to be able to guarantee correct service.

THE LABEL OF THE FAN WILL ALWAYS INDICATE IF THE APPARATUS COMPLIES WITH ONE OF THESE SPECIFIC NORMS. IN A CONTRARY CASE, PLEASE CONSULT.
The chosen fan model should never be used to convey gas of a different composition or temperature than that specified by VORTICE S.P.A., nor is it designated for working in surroundings with conditions different from the ones specified. IN ATEX FANS THE TEMPERATURE REACHED BY ANY OF THE SURFACES HAS BEEN CALCULATED SO THE PRESENCE OF THE SPECIFIED GASES CANNOT REPRESENT A RISK OF IGNITION. ANY UNSUITABLE USE OR OVERLOAD OF THE FAN CAN REPRESENT A SECURITY RISK.

FAN RECEPTION AND VERIFICATION

The fans are sent duly packed and their delivery is always carried out for the account and risk of the buyer. Therefore, it is recommended that, upon receiving the merchandise, this be examined very carefully to check that it has not suffered any damage or subtraction during transport. Any resulting claim should be made directly by the buyer to the transport company that made the delivery or to the insurance company as soon as possible.

TRANSPORT AND STORING

The transport companies and intermediate suppliers who have participated in the transport, as well as in the storing of the fan until its final delivery, will be responsible for the damage caused to the apparatus during this period for inadequate transport or storage. They should also make themselves responsible for all the necessary steps to attend to and solve, with the end client, the damage caused that is not covered in this case by the manufacturer’s guarantee.

Through blows or jerks, damage may be caused to the more sensitive components of the fan, such as roller bearings, and motors. transmission components (only groups VHT, VCBPT, y VCMAPT), or the rotating parts “turbines or propellers” (Elements that can even become stuck or deformed and, thus, unbalanced).

During the storing of the apparatus until the moment of its installation, its protection against external agents should be guaranteed. These may be dust, rain, ultraviolet radiation (direct exposure to the sun) high humidity, and the brusque changes in temperature. These noxious agents are the principal causes of precipitated deterioration of the fan, whereby it can be seriously damaged through oxidation of the components or deterioration of its paint.

It is recommended to always manipulate each fan carefully and in an adequate mannwith he detailed graphic orientations. all fans, depending on their weight and constructive characteristics will be delivered in individual cardboard boxes or on pallets. Furthermore, they may be provided with some bracing points situated adequately to anchor them and make displacement with a crane or a pulley.

QUALITY CONTROL

FUNCTIONING: Before their delivery, absolutely all fans are submitted to electrical safety and function tests. Therefore, if the apparatus has not suffered any damage during its transport and is correctly installed by following these instructions, you can be assured of the correct functioning of the apparatus without any problems.

BALANCING: The rotating element “propeller or turbine” of the fan has been dynamically balanced with a residual lack of equilibrium, which does not surpass the tolerances according to the norms ISO1940-1 e ISO10816-1, quality Q 2,5 ó Q 6,3 depending on the models.

Anyway, it is recommended to make a verification before installing the apparatus, whereby you should make said element rotate with the hand and check that said element does not scrape or present any blow or deformation due to damage suffered during transport. Do not install nor turn the fan on should you observe any damage. Before, consult our technical service.

INSTALLATION AND FUNCTIONING OF THE FAN
VERIFY: In the case of fans being directly installed on a wall or a roof, although some support system or additional structure is being used, correct horizontal and vertical leveling of the apparatus should take place. On horizontal bases, said bases will have to be perfectly plain and leveled and must be perfectly set in the case of a concrete base. It should also be verified that all supports are adequate and of sufficient resistance and rigidity to support the weight of the fan, as well as its inertia during the starting phase. In the case of VHCDTE group roof fans, special attention should be paid to conveniently reinforcing the loading point of the fan and care should be given that the roof water tightness is not affected by possible vibrations of the apparatus.

The normal vibrations that the apparatus may cause during its functioning depend in a great measure on the rigidity grade of the structural element where the fan has to be installed.
In this sense, in the case of the models that permit this, it is recommended to use elastic rubber dampers or adequate springs to avoid the transmission of vibrations and noise, whereby in this way the fan is kept in a floating position.

To correctly complete this isolation in the rest of the ducts, elastic gaskets should be applied at the aspiration, as well as at the impulsion of the fan. With this system,m good isolation of the unit can be achieved, but special attention should be paid so that said elements do not, on the other hand, harm the correct compliance of the safety requirements of each installation.

For rigid installations on cement bases or walls that are not correctly aligned, never force the fan structure upon tightening the screws. Before installation, lacking spaces should be completed by using small strips of plates or washers, or filling these with quick-drying cement so that correct support of the fan is guaranteed.

ONLY FOR TRANSMISSION FANS GROUPS VHT, VCBPT, y VCMAPT :
The respective motor and transmission axles of the rotating propeller or turbine element should always be completely parallel. Also, the pulleys should be aligned in such a manner so that one does not stand out more than the other obliging the belts to work in a forced manner. This verification may be made by simply using a metal ruler to measure the minimum length of the center of the axles and by resting one end of the front part of one of the pulleys and at the same time comparing said position with the other pulley.

Various apparatus are available on the market to carry out said alignment. The voltage of the pulleys should be correct, but never excessive, otherwise the rolling bearings may be harmed due to a load excess. NOTE: pay special attention to the nonsparking parts used on the fan and the accomplishment of the ATEX characteristics.

ELECTRICAL CONNECTION AND INSTALLATION: THE CONNECTION SCHEME HAS TO BE DONE ONLY INSIDE THE MOTOR’S TERMINAL BOX. IN THE CASE OF INTERMEDIATE CONNECTIONS, APPROPRIATE CONNECTION BOXES THAT COMPLY WITH THE ATEX REQUIREMENTS OF THE RISK ZONES MUST BE USED. ALL THE PARAMETERS INDUCED IN THE MOTOR MUST BE UNDER CONTROL AND MONITORIZATION (VIBRATION, TEMPERATURE, ETC.). (please read carefully the instruction manual for the ATEX motor).

IT IS IMPORTANT THAT THE POWER SUPPLY LINES AND OTHER COMPONENTS USED IN THE INSTALLATION COMPLY WITH THE DIRECTIVE ATEX AS WELL AS WITH REGULATIONS IN FORCE ON INDUSTRIAL INSTALLATIONS (“Low voltage electrical regulation”) and therefore protection systems that are adequate to the voltage of the apparatus will be used (motor protection system, differential protection, line limitation and grounding).

For motors superior to 7,5 CV (5,5 Kw) it is recommended to carry out timed or electrically controlled start-ups to avoid excessive consumption points and to obtain more gentle start-ups. Some of the fan models equipped with very heavy turbines (groups VCMAPD and VCMAPT, and more concretely, for its ranges AA y MB P/R) require quite prolonged start-up times. In these cases, the use of a controlled start-up is obligatory. In the case of other models about the same groups of middle and high-voltage centrifugal fans, it will be sufficient to use a regulation shutter or valve, which should be completely closed during the fan’s start-up to reduce consumption.

ALL FAN WIRING ELEMENTS AND COMPONENTS SHOULD BE SELECTED AND INSTALLED CORRECTLY TO COMPLY WITH THE ATEX DIRECTIVE. SPECIAL ATTENTION MUST BE PAID SO ALL METALLIC STRUCTURAL PARTS REMAIN CORRECTLY CONNECTED TO THE GROUND. THUS, AVOIDING THAT ANY ELEMENT REMAINS ELECTRICALLY LOADED AND AVOIDING THE RISK OF ELECTROESTATIC DISCHARGES.
Especially in the models of ranges where thus indicated, the connection should always be carried out using thermic protection that incorporates the motor (SEE THE SECTION ABOUT MAINTENANCE OF THE FAN).

VOLTAGE AND FREQUENCY: Read thoroughly the ATEX motor manual instructions. The motor power supply should be made by the voltage and frequency indicated on the plaque of the fan. Variations of ± 5% in the electrical network about the nominal voltage indicated are permitted. If the connection used cannot maintain this level, there is
a danger of burning out the motor. Therefore, assure yourself that the selected Y-disposition in the motor corresponds to the network voltage and frequency through a tester.

CONSUMPTION : Once the fan is installed in the foreseen working conditions that do not surpass those indicated on the plaque, control the consumption in (A). The fan’s capacity and the installation load should be correctly adjusted (SEE

THE SECTION FUNCTIONING). In case of non-compliance, consult the manufacturer.

GROUNDING: Since the fan is a Class I machine according to the norm in force, it is obligatory to correctly carry out the connection of the grounding through the thus foreseen socket, which can be found inside the motor or fan terminals casing. Once said the connection has been carried out, it is recommended that the resistance between the exterior conductor and the fan
casing should not be superior to 0,1.

ENVIRONMENTAL CONDITIONS: Very important: for normal service (not emergency), never exceed the specified maximum gases continuous temperature specified in all models. This is especially important in ATEX models. The temperature of the fluid itself should never exceed 60ºC. In the case of high- pressure fans, heating of the gas inside the fan due to compression shall also be considered and verified by calculation. Verify first that the fan is labeled with the correct temperature class “T1 to T6”. Verify in the motor plate that the same temperature class or higher is specified.

Finally, verify that the thermal class of the motor (F or H) is the correct one. All of the delivered motors of the fans from VORTICE S.P.A. are usually CLASS F, but there may be exceptions. But independently of the motor’s thermic class, it is recommended not to surpass an air temperature of 40ºC and to keep the humidity inferior to 60% in the cooling surroundings of the motor to guarantee correct refrigeration of the motor and, at the same time, prolong its duration.

The maximum air temperature to be conveyed working on a continuous service basis is from 40ºC a 55ºC for the models that have the motor inside the airflow and about 130ºC for the models with the motor outside the airflow (some models equipped with refrigeration head runners in the motor axles may also work at more elevated temperatures).

In ATEX applications, consult the carried gases temperature’s limit to avoid ignition risk. In each case, it is recommended to consult the information in the technical catalog where the particular characteristics of each fan range and model in a detailed manner. For other more severe applications, some special characteristics may be applied. Always consult the technical sheet for each particular fan and for more information directly contact the manufacturer.

ROTATION DIRECTION: The same as the one indicated by the arrow situated on the fan’s casing. To invert the three-phase rotation of a one or two- velocity motor, interchange the two phases among themselves. In the case of mono-phase motors, this can be changed only by some of the models. Consult the diagrams in each case.

SOUND LEVEL : Depending on the model of the fan, its voltage, size, and revolutions, this may oscillate between 37 and 100 dB (A). The sound level corresponding to each concrete model is specified in its technical sheet. If the fan needed does not comply with the limitations of the maximum noise level allowed where it has to be installed, other alternative solutions should be searched for to reduce this sound level through the application of silencers, barriers, or soundproofing cases.

CONNECTION TO DUCT INSTALLATIONS: In the cases where the fan is connected to a duct network for air distribution, the aspiration and impulsion ducts should be correspondingly connected to the corresponding fan nozzle using the adaptation flanges foreseen by the manufacturer. It is recommended that together with said flanges elastic gaskets should be used whenever possible (both accessories should be ordered separately from the fan and they also should comply with the ATEX requirements). Furthermore, in the case of centrifugal fans, groups VCMAPD and VCMAPT, it is recommended to also use adequate elastic dampers (SEE THE SECTION “INSTALLATION AND FUNCTIONING OF THE

FAN”. Should they be connected directly, they should always be situated correctly so that no harmful forcing or tension appears for the fan. In no case should the duct network lean its weight on the fan. These should dispose of their means of support. It is also recommended to leave a duct element that can be dismantled on both sides to make access available to the fan’s nozzles and in such a manner that there is enough space once the adaptation flanges are taken off this permits a worker to accede the apparatus without any problem. In the case of axial fans VHD and VHT, reductions in the conducts should not be applied, whereby at least the nominal diameter of the fan should be maintained.

PROTECTION AGAINST INVOLUNTARY ACCIDENTS: For all of the fan models, VORTICE S.P.A. disposes of protection for the rotating body (propeller or turbine) according to UNE EN 294. The installer or final user should solicit and install the necessary protection elements to protect the accesses to the interior part of the fans that remain open and accessible due to not being within a duct. IMPORTANT: The turbine or propeller may
not be visible when it is rotating in deficient illuminative conditions.

IP20 PROTECTION FOR AIR INLETS AND OULETS OF THE FAN: In ATEX applications it is requested an IP20 protection. In casthe e of a ducted installation, the installer is responsible for assuring such protection. In case of a free inlet or outlet installation, the final user has to assure that the suitable protection guard (accessory) for the fan is mounted.

STARTING UP: Once all of the previous verifications have been carried out and in case of not having observed any type of anomaly, the starting up of the fan can be carried out. But before proceeding to the first starting-ups, it is recommended to again verify, either directly or through inspection registrations of the apparatus, that there is no friction of any of the rotating elements because some installation element might have forced or deformed the fan. Also, inspect to see that no foreign bodies nor material proceeding from the installation of the fan in the ducts are present.

The first start-up should be of short duration and only to verify that the rotating direction is correct according to the indications and to listen if any strange or friction noises are present in the inside part. In the case of presenting an incorrect rotation, you should proceed to carry out the connection changes according to what is previously indicated. During the second start-up, the fan should be allowed to completely reach its nominal velocity once the controlled start-up maneuver, should this exist, has been finalized. If regulation shutters are used, these should be opened so that the fan adapts itself to the required installation conditions.

IMPORTANT : AT THIS VERY MOMENT IS WHEN A STRICT REAL CONSUMPTION CONTROL OF THE APPARATUS SHOULD BE CARRIED OUT THROUGH THE AMPEROMETRIC CLIP AND TAKING CARE NOT TO SURPASS THE NOMINAL CONSUMPTION “In” INDICATED ON THE WORK VOLTAGE PLAQUE THAT IS BEING USED. IN CASE OF SURPASSING SAID CONSUMPTION, STOP THE APPARATUS IMMEDIATELY.

Excessive consumption may be due to a possible failure of the motor, friction of some element, or an error committed in the electrical connection, but in the majority of cases, this will be due to a deficient adaptation of the installation because of an excessive or defective load. If it is a matter of an axial fan, groups VHD y VHT, it is more than likely that some element that excessively closes the air pass has been installed. On the contrary, if the problem appears in a centrifugal fan, groups VCBPD, VCBPT, VCMAPD, and VCMAPT, the air pass should be closed more through the regulation shutter, if this exists, or by adding some kind of metal strip that closes part of the discharge or aspiration duct of the fan.

IMPORTANT : do not mount any part directly on the fan, since it could alter the fan’s nonsparking characteristics. In this latter case, you should above all assure yourself of not using badly anchored elements, which could be sucked into the fan once it is turned on. Once the installation has been readjusted, again verify that the consumption is adequate. After having achieved this adjustment, the fan can then function without any problems.

FAN MAINTENANCE GENERAL CARE
It is recommended to carry out a complete revision of the fan and its installation once 24 hours of functioning have passed, disconnecting it from the electrical network to avoid possible accidents. WE RECOMMEND THE USE OF ATEX SPECIAL SAFETY SWITCHES for this service. Make sure that no element has come loose, and especially in the case of the transmission groups VHT completely retightens all of the elements: pulleys, belt tensors, motor supports and axles, etc. Also, verify the condition of the motor or transmission bearings by turning the propeller or turbine by hand. Should any anomaly or noise be noticed, consult with the manufacturer.

In the case of installations where the fan is normally switched off, make periodic inspections at least every 6 months. Verifying that the condition of all of the fan’s components maintains the correct initial state and not noticing, in any case, signs of bearings sticking or making noise. It is also recommended to carry out a complete start-up, leaving the fan functioning for one hour. IMPORTANT: All of the models where this protection is indicated have a thermic protector incorporated, which can temporarily detain the functioning of the motor. Therefore, never manipulate the apparatus before disconnecting it from the electrical network. In the case of three-phase models, said protection activates the maneuver circuit on an electrical installation ccocontractorNSIDERATIONS DURING THE REVISION: Points to be taken into account during the revision to guarantee the correct functioning of the fan:

1. The functioning of the fan has to be gentle and free of vibrations.
2. The consumption in amperes “la(A)” measured through an ammeter or multimeter should never surpass the nominal consumption “In(A)” specified on the motor plaque.
3. It has to be verified that all of the elements joined through screws have not come untightened. In the case of transmission fans, groups VHT, VCBPT, and VCMAPT, revise the pulleys, tensioning, and condition of the belts. The belts should function with regularity and without jolts, they usually dilate as time goes by especially during the first weeks of functioning, due to which it is of absolute necessity to readjust them taking care that the gear shifts maintain their alignment once the operation has finalized. In the case of transmission with more than one belt, the entire set will always be replaced. Never mix new belts with already used belts. USE ALWAYS ANTISTATIC BELTS IN ATEX MODELS.
4. In the case of applications where fans convey gases with a high content of dust or grease, these may become unequally adhered to the propellers, due to which may result in a lack of equilibrium of the turbine or propeller with the consequent deterioration of the bearings. TO PRESERVE THE GOOD REFRIGERATION AND OPERATION OF THE MOTOR, ALWAYS PREVENT THE ACCUMULATION OF DUST ON ITS SURFACE. Therefore, periodical cleaning of the rotating body should take place, whereby the installation pauses should be taken advantage of, and every time the fan presents light vibration signs and incorrect functioning. Never leave the loose dust inside the fan.
5. In the case of other applications where abrasive dust accumulations exist, the result may be wear of the propeller, as well as in the case of centrifugal fans used in material transport, groups VCMAPD or VCMAPT (turbines with straight blades. These should be replaced in case of lack of equilibrium due to wear.
6. In the case of fans that have been switched off or stored for a period of two or more years, it is recommended to carry out a complete revision of the ball bearings. Before starting up the fan, the replacement of the ball bearings should take place if you notice that they have been affected by oxidation or by dried-out grease in bad condition.

CLEANING : Attention, maintenance, and correct cleaning of all the installation’s components will be carried out periodically by the persons responsible for the installation. Whenever possible, the accumulation of dirt, dust, grease, etc. should be avoided, since this is the principal cause of the fire and its propagation.

GREASING : The greasing instructions for different elements of the fan should be clearly distinguished:

1. Generally, the electric motor bearing does not need maintenance; notwithstanding, it is recommended not to surpass the limit of hours established and indicated in the manufacturer’s manual of the motor (15.000 a 20.000h according to the brand and the case given to replace them).
2. The transmission groups of the axial ranges HH and HHp and the bearings used in the centrifugal range BV also do not need greasing but should be replaced every 10.000 a 15.000h in function of the temperate and humidity conditions of the air to be conveyed. In the 2GD category, never use bearings under a 40.000h life.
3. The self-aligning bearing supports type NP used in the groups VCBPT and VCMAPT and especially in the case of the more reinforced models, dispose of external greasers, or, should these not be present, are prepared for their installation. In these cases said bearings also do not need maintenance since it is a matter of sealed bearings, but if the work conditions are very extreme, their duration can be prolonged by greasing them every 500 to 1000 hours of functioning. It is very important not to ever mix grease of different viscosity and chemical composition.
