PRECAUTIONS

The ACOUSTIC PRESSURE’s value measured at 4 m in free field

corresponds to the ACOUSTIC POWER’s value stated on the yellow label

located on the compressor, minus 20 dB.

THINGS TO DO

•The compressor must be used in a suitable environment (well

ventilated with an ambient temperature of between +5°C and +40°C)

and never in places affected by dust, acids, vapors, explosive or

flammable gases.

•Always maintain a safety distance of at least 4 meters between the

compressorandtheworkarea.

•Anycoloringofthebeltguardsofthecompressorduringpaintingoperations

indicatesthatthedistanceistooshort.

•Inserttheplugoftheelectriccableinasocketofsuitableshape,voltage

andfrequencycomplyingwithcurrentregulations.

•For 3-phase versions, have the plug fitted by a qualified electrician

accordingtolocalregulations.Whenstartingthecompressorforthefirst

time, check the correct direction of rotation and that this matches the

direction indicated by thearrow on the belt guard (versions with plastic

protection)oronthemotor(versionswithmetalprotection).

•Useextensioncableswithamaximumlengthof5metersandofsuitable

cross-section.

•Theuseofextensioncablesofdifferentlengthandalsoofadaptersand

multiplesocketsshouldbeavoided.

•Alwaysusetheswitchofthepressureswitchtoswitchoffthecompressor

orusetheswitchoftheelectricpanelformodelsequippedwiththis.Never

switchoffthecompressorbypullingoutthepluginordertoavoidrestart

withpressureinthehead.

•Alwaysusethehandletomovethecompressor.

•Whenoperating,the compressormustbe placedona stable,horizontal

surfacetoguaranteecorrectlubrication.

• Position the compressor at least50 cm fromthe wall topermit optimal

circulationoffreshairandtoguaranteecorrectcooling.

THINGS NOT TO DO

•Neverdirectthejetofairtowardspersons,animalsoryourbody.(Always

wearsafetygogglestoprotectyoureyesfromflyingobjectsthatmaybe

liftedbythejet).

•Neverdirectthejetofliquidssprayedbytoolsconnectedtothecompressor

towardsthecompressor.

•Neverusetheapplianceinyourbarefeetorwithwethandsorfeet.

•Neverpullthepowercabletopulltheplugoutofthesocketortomovethe

compressor.

•Neverleavethe applianceexposedto adverseweatherconditions (rain,

sun,fog,snow).

•Nevertransportthecompressorwiththereservoirpressurized

•Neverweld or machine the reservoir.In the case of faultsor corrosion,

replaceitcompletely.

•Neverallowinexpert personstouse thecompressor.Keep childrenand

animalsawayfromtheworkarea.

•Neverpositionflammableornylonorfabricarticlesclosetoand/oronthe

compressor.

•Never clean the compressor with flammable liquids or solvents. Clean

witha damp cloth only,after making sure that you haveunplugged the

compressor.

•Thecompressorisdesignedonlytocompressairandmustnotbeusedfor

anyothertypeofgas.

•The compressed air produced by the compressor cannot not be used

for pharmaceutical, food or hospital purposes except after particular

treatments.Itisnotsuitableforfillingtheairbottlesofscubadivers.

•Neveruse the compressor without guards (belt guard) and never touch

movingparts.

THINGS YOU SHOULD KNOW

•To avoid overheating of the electric motor, this compressor is

designed for intermittent operation as indicated on the dataplate(for

example,S3-50means5minutesONand5minutesOFF).Inthecaseof

overheating,thethermalcutoutofthemotortrips,automaticallycuttingoff

thepowerwhenthetemperatureistoohighduetoexcesscurrenttake-

off.

•To facilitate machine restart, it is important not only to carry out the

operations indicated but also to set the button of the pressure switch,

returning this to the OFF position and then ON again (figures 1a-1b).

•Onsingle-phaseversions,presstheresetbuttonontheterminalboxofthe

motor(fig. 2).

•On 3-phase versions, operate manually on the button of the pressure

switch,returningthistotheONposition,orpressthebuttonofthethermal

cutoutinsidetheboxoftheelectricpanel(figures 3a-3b-3c).

•Thesingle-phaseversionsarefittedwithapressureswitchequippedwith

adelayedclosingairventvalve(orwithavalvelocatedonthecheckvalve)

thatfacilitatesmotorstart-up;thereforeafew-secondjetofairfromthis,

withthereservoirempty,istobeconsiderednormal.

•Toguaranteemachinesafety,allthecompressorsarefittedwithasafety

valvethatisactivatedinthecaseoffailureofthepressureswitch(fig. 4).

•All two-stage compressors are equipped with safety valves on the air

deliverymanifoldtothereservoirandontheconnectionhosebetweenthe

lowandhighpressurelocatedonthehead.Theseareactivatedinthecase

ofmalfunctioning(fig. 5).

•When connecting an air-powered tool to a hose of compressed air

suppliedbythecompressor,interruptionoftheflowofairfromthehoseis

compulsory.

•Useofthecompressedairforthevariouspurposesenvisaged(inflation,

air-powered tools, painting, washing with water-based detergents only,

etc.)requiresknowledgeofandcompliancewiththerulesestablishedfor

eachindividualuse.

START-UP AND USE

•Fitthewheelsandfoot(orthecasterwheelformodelsthatarefittedwith

this)accordingtotheinstructionsprovidedinthepackaging.Forversions

withfixedfeet,assemblethefrontbracketkitorthevibration-dampersif

furnished.Checkthattheratingdatamatchtheeffectivecharacteristicsof

thesystem(voltageandpower).

•Check for correspondence between thecompressor platedata with the

actual specifications of the electrical system.A variation of ± 10% with

respectoftheratedvalueisallowed.

•Insertthepowerpluginasuitablesocketcheckingthatthebuttonofthe

pressure switch located on the compressor is in the “O” (OFF) position

(figures 6a-6b-6c-6d).

•Forthe3-phaseversions,connecttheplugtoapanelprotectedbysuitable

fuses.

•For the versions fitted with electric panel (“Tandem” control units or

delta/starstarters)haveinstallationandconnections(tothemotor,tothe

pressure switch and to the electrovalve if any) carried out by qualified

personnel.

•Checktheoillevelusingthesightglassandifnecessaryunscrewthevent

plugandtopup.(figures 7a-7b).

•Atthispoint,thecompressorisreadyforuse.

•Operatingontheswitchofthepressureswitch(ortheselectorforversions

It is then routed, through the recirculation hose, into the so-calledhigh

toreachhigherpressure,withavailabilityofairat11bar(15barforspecial

machines).

deliveryhosethroughavalvelocatedunderthepressureswitch(indelta/

star versions, through an electrovalve that is activated when the motor

stops).

•The absence of pressure in the head facilitates subsequent restart.

Whenairisused,the compressorrestartsautomaticallywhen thelower

calibration value is reached (approx. 2 bar between upper and lower).

Thepressureinsidethereservoircanbecheckedonthegaugeprovided

(fig. 4).

•Thecompressor continues to operate automatically with this workcycle

untilthepositionoftheswitchofthepressureswitch(oroftheselectorof

again, wait at least 10seconds after thishas beenswitched offbefore

restarting.

•In the versions with electric panel, thepressure switch mustalways be

alignedwiththeI(ON)position.

•Intandemversions,the controlunitprovided permitsuseof onlyoneof

thetwo compressor groups (ifnecessary alternatively) or of bothat the
