2.1 IMPORTANT F400
All F400 fans (400°C/2h) manufactured by Woods Air Movement and described in this manual are approved
according to the UNE EN 12101-3/2002 standard in order to comply with the CTE 2006.D.C.B97106CEE directive
(FORMERCPI196),andarethereforespecicallyrecommendedforemergencysmokeextractionincaseofre.
The selected model can be installed either inside the risk zone (IMMERSED DUTY MODELS with F400 motors), or
used to carry high temperature gases (EXTERIOR DUTY MODELS); in this case, they must be installed outside the
risk zone. The exterior models are equipped with normal-serial motors and other elements which are not suitable
foruseintherezone.
F400 FAN SERVICE MUST ALWAYS BE VERIFIED IN THE FAN LABEL F400- IMMERSED // F400 EXTERIOR DUTY.
ALL F400 WOODS AIR MOVEMENT FANS ARE SUITABLE FOR EXTERIOR DUTY ONLY.

3. EC APPROVAL AND CORRECT USE OF THE FAN
All fans manufactured and supplied by Woods Air Movement have been manufactured in accordance with the
98/37/CE (MAQUINAS-MACHINES) safety standard and according to the safety standard for low voltage materials
73/23/CE.isalsoextendedtoeachparticularrangeincompliancewiththerequiredspecicstandards.
In general, all the fan applications where an electronic velocity regulation system is needed require consultation
and authorisation by Woods Air Movement and should comply with the electromagnetic compatibility 89/336/CEE
standard.
The unauthorised use of any type of electronic controller with the fan can be very dangerous and render all
security devices useless, and does not comply with F400 requirements.
For maximum safety in fan maintenance, Woods Air Movement recommends the installation of a SAFETY STOP/
START SWITCH, with manual disconnection. These devices must also be accredited to F400.
IMPORTANT: THIS PARTICULAR FAN MAY NOT BE SUITABLE FOR THE SAFETY REQUIREMENTS OF YOUR
INSTALLATION. PLEASE VERIFY THAT THE CHARACTERISTICS SPECIFIED IN THE APPARATUS COMPLY WITH THE
APPLICATION REQUIREMENTS BEFORE ITS INSTALLATION. VERIFY THAT THE GROUP, CATEGORY, AND CLASS
TEMPERATURE SPECIFIED IN THE CHARACTERISTICS PLATE ARE COMPATIBLE WITH THOSE REQUIRED BY THE
INSTALLATION.

4. APPLICATIONS
The requirements and characteristics of each fan model are always determined by the general and local standards
and regulations to which every application may be subject. Therefore, in some cases, the selected standard units
may not be adequate for certain applications, and special characteristics should be incorporated. For example,
unitstobeinstalledinsurroundingswithreorexplosionrisksshouldcomplywiththeATEX94/9/CEstandard
and therefore with the D.C.89/106CEE directive. Other characteristics such as raised work temperature or corrosive
surroundings may also require special models to guarantee compliance.
THE FAN LABEL WILL ALWAYS INDICATE THE APPARATUS COMPLIANCE WITH ANY SPECIFIC STANDARD. FOR
VERIFICATION, PLEASE CONTACT US.
The selected fan model should never be used to convey gas of a composition or temperature other than that
speciedbyWoodsAirMovement,norshoulditoperateinsurroundingswithdierentconditionstothose
indicated IN THE ATEX RANGE OF FANS. THE TEMPERATURE REACHED BY ANY OF THE SURFACES HAS BEEN
CALCULATED TO ENSURE THE PRESENCE OF THE SPECIFIED GASES WILL NOT POSE A RISK OF IGNITION. ANY
UNSUITABLE USE OR OVERLOAD OF THE FAN CAN POSE A SECURITY RISK.
5. FAN RECEPTION AND VERIFICATION
Fans are carefully packed for transport, but their delivery is at the risk of the buyer. It is therefore recommended
that merchandise is carefully checked on arrival for damage that may have occurred during transport. Any claim
for damages should be made immediately by the buyer to the transport company, or to the insurance company
6. TRANSPORT AND STORING
Transport companies and intermediate suppliers who have been involved in the transport and storage of fans until
naldeliverywillberesponsibleforanydamagecausedtotheapparatusduringthisperiod;whichcoversboth
inadequate transport or storage. They are also responsible for pursuing, with the end client, any damages
not covered by the manufacturer’s guarantee.
Knocks or sudden movement may damage the more sensitive components of the fan, such as roller bearings and
motors, transmission components or rotating parts “turbines or propellers” (elements that can become stuck or
deformed and therefore unbalanced).
During the storage of the apparatus, before its installation, it must be protected against anything that may cause
damage. This includes dust, rain, ultraviolet radiation (direct exposure to the sun) high humidity and sudden
changes of temperature. These potentially harmful elements are the principal causes of the deterioration of the
fan, causing serious damage through oxidation of the components or deterioration of its paint.
The fan must be carefully handled in compliance with the detailed instructions provided. Every fan, depending on
its weight and construction, will be delivered in individual cardboard boxes or pallets. They may also be provided
with bracing points placed to anchor them so they may be moved with a crane or pulley.
7. QUALITY CONTROL
7.1 OPERATION
Before delivery, all fans are submitted to electrical safety and operating tests. This ensures that, if the apparatus
hasnotsueredanydamageduringtransportanditiscorrectlyinstalledasindicatedintheseinstructions,itwill
operate correctly.
7.1 BALANCING
The rotating element “propeller or turbine” of the fan has been dynamically balanced with a residual lack of
equilibrium to not surpass the tolerances according to the ISO1940-1 and ISO10816-1 standard, quality Q 2,5
or Q 6,3 depending on the models.
However, we recommend a thorough assessment is carried out before installation; rotating the element by hand
to ensure it does not scrape, and to check there is no damage caused during transport. Do not install or turn on
the fan if there is any damage. Please contact our technical service in this instance
5

8. OUR PRODUCT GUARANTEE
Woods Air Movement will always deliver fans in accordance with the service or installation requirements.
Thereforeallcomponentsusedinthefanwillonlybesuitablefortheowtobeconveyedandtheoperating
conditionsspeciedbythecustomer.
IMPORTANT: Woods Air Movement will not be responsible for accidents caused by incorrect handling of the fan
and omission or non-compliance of any of the recommendations and safety regulations stated in this manual.
8.1 WARRANTY PERIOD
Woods Air Movement fans have a 1-year guarantee from date of purchase (always keep the invoice). The stated
warranty period will expire after a year, even if the fan has not been installed or used immediately after its
purchase from Woods Air Movement. This guarantee excludes any marks, damage or breakdown caused to the
fanitself,ortothirdpartiesaectedbytheincorrectorcarelessuseoftheapparatus,normalwear,overloador
handling by anyone not authorised by Woods Air Movement to carry out technical service. This guarantee includes
the replacement of parts considered defective after examination by our specialists.
Maintenance,possibleadjustmentmodicationsandrepairsofthefanshouldalwaysbecarriedoutbyatrained
specialist. During the warranty period, repairs may only be carried out with previous authorisation by Woods Air
Movement and by authorised workshops and personnel. WOODS AIR MOVEMENT WILL ALWAYS DECIDE WHERE
REPAIRS OF THE APPARATUS UNDER WARRANTY ARE CARRIED OUT, AND THE TRANSPORT COMPANIES USED FOR
THEIR TRANSPORT SHOULD THIS BE NECESSARY. THIS GUARANTEE DOES NOT COVER THE COST OF TRANSPORT
OF SMALL APPARATUS TO THE RECOMMENDED TECHNICAL SERVICE.
9. FAN INSTALLATION AND OPERATION
9.1 VERIFY
For fans due to be installed directly onto a roof, correct horizontal and vertical levelling of the apparatus must be
carried out, even if a support system or an additional structure is being used, Horizontal bases must be perfectly
levelandsetinaconcretebase.Adequatesupportswithsucientresistanceandrigiditytosupportthefanweight
should also be installed. For roof fan products, special attention should be paid to reinforce the loading point of
thefanandensurethattheroofwatertightnessisnotaectedbypossiblevibrationsoftheapparatus.Normal
vibrations of the apparatus during its operation depend mainly on the rigidity of the structure where the fan is to
be installed.
If dampers are necessary to avoid vibrations and noise, only metal springs should be used. F400 - approved elastic
joinsshouldbeusedbothatinletandoutlettoeectivelyisolatethefanfromtheducting.Withthissystem,an
eectiveisolationcanbeachieved.
It is important that these isolation elements do not alter the security compliance of the installation.
In rigid installations on cement bases or walls which are not correctly aligned, never force the fan structure by
tighteningthescrews.Beforeinstallation,anygapsshouldbelledwithsmallstripsofmetalorwithwashers,
orbyllingthemwithquickdryingcement.
9.2 ELECTRICAL CONNECTION AND INSTALLATION
Each fan’s wiring diagrams are available inside the connection box of the motor. PLEASE READ THE INSTRUCTION
MANUAL FOR F400 CAREFULLY. IT IS IMPORTANT THAT POWER SUPPLY LINES AND OTHER COMPONENTS USED IN
THE INSTALLATION COMPLY WITH THE
REGULATIONS ON INDUSTRIAL INSTALLATIONS (“Low voltage electrical regulation”) and therefore protection
systemssuitableforthevoltageoftheapparatusshouldbeused(motorprotectionsystem,dierentialprotection,
line limiter and grounding). For motors superior to 7,5 CV (5,5 Kw), timed or electrically controlled start-ups are
recommended in order to avoid excessive consumption points and to achieve more gentle start-ups. In some
models in the middle and high voltage centrifugal fans, a regulation shutter or valve completely closed during the
fan’s start-up to reduce consumption will be enough.
The cable or cables used should be properly protected to avoid any damage to the fan’s structural components or
their backups, and must comply with the pertinent F400 technical requirements.
6

IN INTERMEDIATE CONNECTIONS, BOXES THAT COMPLY WITH THE F400 DEMANDS MUST BE USED (CAREFULLY
READ THE F400 MOTOR MANUAL INSTRUCTIONS). CABLES CATALOGUED AS “FLAME RESISTANT” WHICH DON’T
GUARANTEE A F400 SERVICE ARE NOT SUITABLE FOR THIS FUNCTION. WOODS AIR MOVEMENT RECOMMENDS
VS OMERIN BRAND CABLES WHICH HAVE BEEN PROPERLY TESTED WITH OUR FANS.
EVERY FAN WIRING ELEMENT AND COMPONENT SHOULD BE CORRECTLY SELECTED AND INSTALLED TO COMPLY
WITH THE F400 STANDARDS. SPECIAL ATTENTION MUST BE PAID TO ALL METAL STRUCTURAL PARTS, WHICH MUST
REMAIN CORRECTLY CONNECTED TO THE GROUND TO PREVENT ANY ELEMENT FROM GETTING ELECTRICALLY
LOADED AND TO AVOID ELECTROSTATIC DISCHARGES.
In the models shown, connection should always be done by using the thermal protection incorporated in the motor
(SEE FAN MAINTENANCE SECTION).
9.3 VOLTAGE AND FREQUENCY
Carefully read the F400 motor manual instructions. The motor power supply should be made in accordance with
the voltage and frequency shown on the fan plate. Variations of 5% in the electrical network for the nominal
voltage indicated are permitted. If the connection used cannot support this level, there may be a danger of the
motor burning out. Therefore, ensure the selected Y-? disposition in the motor corresponds to the network voltage
and frequency by using a tester.
9.4 CONSUMPTION:
Once the fan has been installed, and the load does not exceed that shown on the plate, you can control the
consumption. The fan’s capacity and the installation load should be correctly adjusted (SEE THE OPERATING
SECTION). In case of non-compliance, consult the manufacturer.
9.5 GROUNDING
If the fan is a Class I machine that complies with the current standard, it is vital to correctly carry out connection
of the grounding through the socket, which can be found inside the motor or the fan’s terminal casing. Once this
connection has been carried out, it is recommended that the resistance between the exterior conductor and the
fan casing should not be greater than 0,l?
9.6 ENVIRONMENTAL CONDITIONS
Itisveryimportantfornormalservice(notinanemergency),toneverexceedthespeciedmaximumgases
continuoustemperaturespeciedineverymodel.Thetemperatureoftheuiditselfshouldneverexceed600C.
Inhighpressurefans,heatingofthegasinsidethefanduetocompressionshouldalsobeconsideredandveried
bycalculation.Verifyrstthatthefanislabelledwiththecorrecttemperatureclass“TltoT6”.Makesurethatthe
same,orahighertemperature,classisspeciedonthemotorplate.AllmotorsforexternalF400fanssuppliedby
Woods Air Movement are generally CLASS F.
However, there may be exceptions. In the EXTERNAL models (during normal service of DUAL application), but
independently of the motor’s thermal class, it is recommended that the air temperature does not exceed 40°C, and
to keep the humidity below 60% in the cooling surroundings of the motor. This will ensure the motor is kept cool
and, at the same time, prolong its duration. The maximum air temperature in a continuous service should range
from 400C to 550C.
In each case it is recommended that users consult the information in the technical catalogue to establish the
particular detailed characteristics of each fan range and model. For other more severe applications, some special
characteristics may be applied. Always consult the technical sheet for each particular fan, and for more information
contact the manufacturer.
9.7 ROTATION DIRECTION
This is shown by the arrow on the fan’s casing. To invert the three-phase rotation of a one or two velocity motor,
interchange the two phases. In single phase motors, this can only be changed in some models. Consult the
diagrams in each case.
7

9.8 SOUND LEVEL
Depending on the fan model, its voltage size and revolutions, this may oscillate between 37 and l00dB (A).
Thesoundlevelcorrespondingtoeachconcretemodelisspeciedinitstechnicalsheet.Ifthefandoesnot
comply with the permitted local limitations of maximum noise level, other alternative solutions should be
consideredinordertoreducethissoundlevelbyinstallingsilencers,barriersorsoundproongcases.
9.9 CONNECTION DUE TO DUCT INSTALLATIONS
In cases where the fan is connected to a duct network for air distribution, the suction and impulsion ducts should
beconnectedtothecorrespondingfannozzleusingtheadaptationangesrecommendedbythemanufacturer.
Togetherwiththeanges,elasticgasketsshouldbeusedwheneverpossible(bothshouldberequestedseparately
fromthefan,meetwithF400technicalrequirementsandspecications.Theductnetworkshouldneverleanon
the fan, but be self-supporting.
9.10 PROTECTION AGAINST INVOLUNTARY ACCIDENTS
Through Woods Air Movement, products (accessories) are available that protect the rotating body (propeller or
turbine) in every fan model, according to UNE EN 294. The installer or end user must request and install these
products to protect accesses to the interior of the fan that remains open, accessible and not connected to a duct.
IMPORTANT: The turbine or propeller may not be visible when it is rotating in poorly lit conditions.
9.11 IP20 PROTECTION FOR AIR INLETS AND OUTLETS OF THE FAN
In ATEX applications, an IP20 protection is recommended. In ducted installations, the installer is responsible for
ensuring this protection. In a free inlet or outlet installation, the end user must ensure that the protection guard
(accessory) for the fan is mounted.
9.12 START-UP
Onceallthecheckshavebeendone,start-upofthefancanbecarriedout.Beforeproceedingwiththerststart-
up, it is recommended that another thorough inspection is made to ensure that there is no friction in any of the
rotating elements caused by deformation. It is also vital to check that there is nothing contained within the ducts.
Therststart-upshouldbeshortandcarriedoutonlytocheckthattherotatingdirectioniscorrectaccordingto
thespecications,andifthereareanystrangeorfrictionnoisesintheinterior.Incaseofanincorrectrotation,
connection changes should be carried out as previously stated. During the second start-up, the fan should be
allowed to reach its target velocity. If regulation shutters are used, these should be open so that the fan can adapt
itself to the required installation conditions.
IMPORTANT: AT THIS TIME, A STRICT REAL CONSUMPTION CONTROL OF THE APPARATUS SHOULD BE CARRIED
OUT THROUGH THE AMPEROMETRIC CLIP AND BY MAKING SURE THE USED NOMINAL CONSUMPTION “In”
DOES NOT EXCEED THAT INDICATED ON THE VOLTAGE PLATE. IF THIS CONSUMPTION IS EXCEEDED, STOP THE
APPARATUS IMMEDIATELY.
An excessive consumption may be due to a motor failure, to the friction of some element, or an error in the
electrical connection. In most cases, however, it is due to incorrect installation, with an excessive or defective load.
Iftheproblemoccursinacentrifugalfan,theairowshouldbereduced,eitherthroughtheregulationshutter,or
by adding some kind of metal strip that closes part of the discharge or suction duct of the fan.
IMPORTANT: Do not mount any part directly onto the fan, as it could alter the fan’s non sparking characteristics.
In this instance, ensure no poorly anchored elements are used, as they could be sucked into the fan once it is
turned on. Once the installation has been readjusted, make sure the consumption is adequate. The fan should
operate properly once this adjustment has settled
8

10. FAN MAINTENANCE
10.1 GENERAL CARE
Acompleterevisionofthefananditsinstallationaftertherst24hoursofoperationisrecommended.
Disconnect it from the electrical network to avoid any possible accidents. F400 APPROVED SAFETY SWITCHES ARE
RECOMMENDED for this service. Make sure no parts have come loose, and completely retighten all parts: motor
supports and axles, etc. Also, check the condition of the motor or transmission bearings by turning the propeller or
the turbine with your hands. If you notice any abnormality or noise, consult the manufacturer.
InwIninstallations,wherethefanisgenerallyswitchedo,inspectionsshouldbecarriedoutatleastevery6
months.
An inspection of the fan’s components will ensure it remains in good condition, as long as there is no evidence
of bearings sticking, or noise. It is also recommended that a complete start-up is carried out, allowing the fan to
operate for one hour.
With wIn dual and only in emergency applications: It is recommended that the motor is replaced every 16,000
hours of operation.
F400 MOTORS USED FOR REPLACEMENT IN APPROVED FANS MUST BE AUTHORISED BY WOODS AIR MOVEMENT.
EVEN IF THE REPLACED MOTOR IS APPROVED, IT MAY HAVE NO VALIDITY WITH THIS PARTICULAR FAN.
FANS SUBMITTED TO AN EMERGENCY SERVICE IN CASE OF FIRE CANNOT BE REPAIRED. THEY MUST BE REPLACED
BY A COMPLETELY NEW UNIT WITH THE SAME CHARACTERISTICS AND APPROVED FOR F400.
IMPORTANT: Some models have a thermal protector incorporated which can temporarily stop the motor
operation. Therefore, never manipulate the apparatus before disconnecting it from the electrical network.
In three-phase models, this protection activates the manoeuvre circuit on an electrical installation contact.
10.2 CONSIDERATIONS DURING THE REVISION
Points to be taken into account during the revision in order to guarantee a correct operation of the fan:
1. The operation of the fan has to be gentle and free from vibrations.
2. Consumption in amperes “la(A)” measured through an ammeter or multi-meter should never exceed
consumption“In(A)”speciedonthemotorplate.
3. Make sure all the elements joined with screws are tight.
4. In applications where fans convey gases with a high content of dust or grease, particles may become stuck to
the propellers, leading to a lack of equilibrium of the turbine or propeller and resulting in the deterioration of
the bearings. AVOID THE ACCUMULATION OF DUST ON THE MOTOR SURFACE TO AVOID INADEQUATE COOLING
AND OPERATION. Frequent cleaning of the rotating body should be done during pauses in installation, and every
time the fan develops light vibration and is not operating correctly. Never leave loose dust inside the fan.
5. In other applications with abrasive dust accumulations, the propeller may become worn. If there is lack of
equilibrium caused by wear, these should be replaced.
6.Infanswhichhavebeenswitchedoorstoredfortwoormoreyears,acompleterevisionoftheballbearings
isrecommended.Beforestartingupthefan,ballbearingsshouldbereplacediftheyhavebeenaectedby
oxidation, or by dried out grease.
10.3 CLEANING
Attention, maintenance and cleaning of all the installation components should be carried out on a regular basis
by the personnel responsible for the installation. Whenever possible, the accumulation of dirt, dust, grease, etc.
shouldbeavoided,asthisisthemaincauseofre.
10.4 GREASING
Thegreasinginstructionsfordierentelementsofthefanshouldbeclearlydistinguished:Thegreasing
instructionsfordierentelementsofthefanshouldbeclearlyfollowed:
1. Generally, the electric motor bearings do not need maintenance; but the number of hours recommended in the
manufacturer’s manual should not be exceeded; (15,000 to 20,000h according to the brand). In this case, the
motor should be replaced.
2. Transmission groups of the axial ranges and the bearings used in the centrifugal range BV do not need greasing,
but they should be replaced every 10,000 a 15,000h, depending on the temperature and humidity of the air to
be conveyed.
