VIAIR 400P - Operating Instructions

400P AUTOMATIC PORTABLE COMPRESSOR
OPERATING INSTRUCTIONS:
Pleasereadandfollowtheoperatinginstructionscarefullytoassurethatyouwillenjoythe
convenienceandbestuseoutofyouraircompressor.
1.AlwaysoperatethecompressorATORBELOWTHEMAXIMUMPRESSURERATINGofthe
 compressor.RefertoSpecicationssectionofthismanual.
2.AlwaysOBSERVETHEMAXIMUMDUTYCYCLEoftheaircompressor.RefertoSpecications
 sectionofthismanualfordetails.Operationsexceedingmaximumpressureratingsandorduty
cycle will result in damage to air compressor.
3.YouraircompressorisequippedwithanAUTOMATICTHERMALOVERLOADPROTECTOR.
 Thisfeatureisdesignedtoprotecttheaircompressorfromover-heatingandcausingpermanent
 damagetoyouraircompressor.Thethermaloverloadprotectorwillautomaticallycutoffpower
 toaircompressorshouldinternaloperatingtemperatureoftheaircompressorriseabovesafe
 levelsduringexcessiveuse.
4.Shouldyourcompressorshutoffsuddenlyafterextendeduse,donotattempttorestartair
 compressor.TurnON/OFFswitchofaircompressortotheOFFposition.Theautomaticthermal
 overloadprotectorwillautomaticallyresetwheninternaltemperatureoftheaircompressordrops
 belowsafelevel.Afterallowingaircompressortocooloffforabout30minutes,youcansafely
resume use of the air compressor by turning on the air compressor.
5.Foryourconvenience,andtoprotecttheaircompressorfromover-pressureoperationthatcan
cause permanent damage to the unit - this compressor is equipped with built-in pressure switch
 withafactorysetcut-onpressureof120PSI(±5%)andafactorysetcut-offpressureof
 145PSI(±5%).Duringinationoftirepressuresbetween115PSIto145PSI,ifyoustopination,
the compressor may not restart. This is completely normal, since inline pressure is greater than
cut-on pressure of the pressure switch and less than cut-off pressure of the pressure switch.
 Torestartcompressor,deatetirepressuretobelow115PSI,reconnecttirechucktotirevalve
 stemandresumetireination.
6.Pleasenotethatyoumayexperienceaslightdelay(about_second)ofthecompressor’smotor
 startingwhentheON/OFFswitchisturnedonwhilecompressorispressurized(whenthereis
 pressureinthelinethatthecompressorisconnectedto).Thisisanormaldelayedreaction,
 notaCompressorON/OFFswitchmalfunction.
7.Itisstronglyrecommendedthatyoukeepthevehicle’senginerunningwhileusingtheair
 compressortopreventdischargeofyourvehicle’sbattery.
8.ONLYOPERATETHEAIRCOMPRESSORINWELLVENTILATEDAREAS.
 Compressorperformanceisenhancedwhenoperatingcompressorwithvehicleenginerunning.
IMPORTANT:Enginemustberunningwhileusingthiscompressor.
Beforeattachingaircompressorpowerclampstoyourvehicle’sbatteryterminals,checktomake
surethattheON\/OFFswitchofyourcompressorisintheOFFposition.AttachthePositive(+)
batteryclamp(Red)tothePositiveterminalofthebatteryandtheNegative(-)batteryclamp(Black)
totheNegativeterminalofthebattery.Alwayskeepyourvehicle’senginerunningwhileoperating
compressortoavoiddrainingyourvehicle’sbattery.
CAUTION:YourPortableAirCompressorisMoistureandDustResistant,butNOTWATERORDUST
PROOF.Neverplacecompressorinsoftsandwhilerunningthecompressor.Vibrationfromthe
compressor will cause the compressor to settle into soft sand, resulting in compressor drawing in
foreignparticles.Neverexposecompressortowaterwhilerunningthecompressor.
