INSTALLATION
Thisaircompressorisidealformountingunderthehoodoreveninsideyourvehicle.Thecompact
sizeofthiscompressorrequiresminimalspace,andoil-lessdesignpermitsmountinginmany
differentareasofyourvehicle.PleasereadandfollowtheseInstallationInstructionscarefullytoavoid
injuryordamagetothecompressororyourvehicle.
Eachofouraircompressorsandpartshavebeencarefullyproducedandpackaged.Beforeyou
begininstallation,pleasefamiliarizeyourselfwithInstallationPartsList(Fig.1)ofthismanual.
Guidelines for Selecting Mounting Location:
The selection of proper mounting location for your air compressor will help ensure a long and
troublefreecompressorservicelife.Pleasepay close attention to the following guidelines:
1. Select a FLAT,UPRIGHTANDSECURE location where the compressor can be mounted.
2.Tomaximizeaircompressorperformance,locatecompressorasCLOSETOTHEBATTERY
aspossiblesothatlengthofpositiveleadwirerequiredisataminimum.
3.ChoosemountinglocationthatisascoolaspossibleandAWAYFROMHEATSOURCES.
Thecoolertheambienttemperaturethelesschancethecompressorwilloverheat.
4. This compressor is moisture & splash resistant, but NOTWATERPROOF. Do not mount
compressorinlocationswheretheunitislikelytocomeincontactwithwater.
5. Select compressor mounting location where air line can be routed from compressor air inlet to
remoteinletairlter.MakesureRemoteInletAirFilterislocatedinadrylocation,awayfrom
water splashes.
6.Youwillalsowanttoselectacompressormountinglocationwheretheleaderhosebracket
can be mounted to secure the 1.5 ft. leader hose.
7. If it is necessary to mount the air compressor further away from the battery, such as inside
yourvehicleorinthebedofyourpickup,useaminimum8AWGpositiveleadwirefor
remoteinstallation.(Seewiregaugereferencechart)
