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.
Selecting a 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ORDUSTPROOF. Do not mount
compressor in locations where the unit is likely to come in contact with water.
5. 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16AWGpositiveleadwireforremote
installation.(Seewiregaugereferencechart)
6.Donotmountcompressornearareaswhereammableliquidsarestored.

and cut ground wire to length as needed.
4. Mountaircompressorwiththefoursetsof0.15"(4mm)bolt,nuts,washers,and
lockingwashersandrubberwashersprovided.(SeeFig.1forMountingInstructions)Useof
thread sealant recommended.
5. Connectcompressor'spositiveleadwiretooneoftheleadsofyourpressureswitch.
6. Makesurethatyourcompressorsetupisproperlyfused.Forappropriatefusesize,refer
to-Ampdrawofcompressorinthespecicationssectionofthismanual.
7. Alwayslocatefuseascloseaspossibletopowersource.
8. Before connecting to power source, re-check to make sure a that all connections are
properly connected.
9. Connect and test compressor system by running the compressor for a short time to build
up pressure in your air tank.
10.Onceairpressurereachespresetcutoutpressureofyourpressureswitch,thecompres-
sorwillshuto.Inspectallairlineconnectionsforleakswithsoapandwatersolution.Ifa
leakisdetected,theairlinemaynotbecutsquarelyorpushedallthewayin.Fixairtting

ABOUT COMPRESSOR DUTY CYCLE:
Duty cycle refers to the amount of time a compressor can be
operatedinagiventimeperiodat100PSI,andastandardambienttemperatureof72°F.Itis
commonlyexpressedinpercentageformat:Compressorontime÷(ontime+otime)=Duty
Cycle%.

NOTE:Allcompressors,regardlessofrateddutycycle,requiresucientresttimeinbetween
cyclestoallowforpartialorcompleteheatdissipation.Heatdissipationratesmayvarydepending
on ambient temperatures and operating conditions.
ABOUT RATED WORKING PRESSURE:
Toensuretroublefreeservicelifeofyourcompressor,alwaysoperatecompressorwithinrated
workingpressureofthecompressor.Neveruseapressureswitchwithahighercut-opressure
thancompressor'sratedworkingpressure.
