INSTALLATION
Pleasereadandfollowtheinstallationinstructionscarefullytoavoidinjuryordamagetothe
compressorand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compressor’s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fartherawayfromthebattery,suchas
insideyourvehicleorinthebedofyourpickup,useaminimum16AWGpositiveleadwire
for remote installation.
8.Donotmountcompressornearareaswhereammableliquidsarestored.
9.Usethreadsealantforproperttinginstallation.Teontapeisnotrecommended.
