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&dustresistant,butNOTDIRTORWATERPROOF. Do not mount
compressor in locations where the unit is likely to come in contact with the elements.
5.Forcompressorwithremoteltermounting,selectcompressor’smountinglocationwhereairline
canberoutedfromcompressorairinlettoremoteinletairlter.Makesurethattheremoteinletair
