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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WATERPROOF.
Do not mount compressor in locations where the unit is likely to come in contact with water.
5. Forremoteltermounting,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theelements.
6. Youwillalsowanttoselectcompressormountinglocationwheretheleaderhosebracket
can be mounted to secure the leader hose.
7. Ifitisnecessarytomountaircompressorfurtherawayfromthebattery,suchasinsideyour
