PRECAUTIONS

1

These compressors are not suitable for outdoor use.

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suppliedwheelsasshowninfigures19a-19b and 20a-20b.Forversions

withfixedfeet,assemblethevibration-dampersiffurnished.

•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

•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.

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

•Please check that the air consumption and the maximum working

pressure of the pneumatic tool to be used are compatible with the

pressure set on the pressure regulator and with the amount of air

supplied by the compressor.
