Before using your vacuum pump...
 Note on Motor Voltage Connections:
Inallcases,motorsaredesignedforoperatingvoltages,plusorminus
10%ofthenormalrating(seeSPECIFICATIONS).Singlevoltage
motorsaresuppliedfullyconnectedandreadytooperate.
 1.Verifythatthevoltageandfrequencyattheoutletmatchthe
specicationsonthepumpmotordecal.PlacetheON/OFFswitchin
theOFFpositionbeforeyouplugthepumpintoanoutlet.Verifythegas
ballastvalveisclosed.Removeanddiscardtheexhaustplugfromthe
endofthepump’shandle.
 2.Thepumpisshippedwithoutoilinthereservoir.Beforestartingthe
pump,llitwithoil.RemovetheOILFILLcap(blackplasticplug
directlyinfrontofthehandle),andaddoiluntiltheoiljustshowsinthe
bottomofthesightglass.Theapproximateoilcapacityofthepumpis
15ounces.
 3.ReplacetheOILFILLcap,andremovethecapfromoneoftheinlet
ports.OPENtheIso-Valve™.TurnONthemotorswitch.Whenthe
pumprunssmoothly,CLOSEtheIso-Valve™,andreplacethecaponthe
inletport.Thismaytakefromtwoto30secondsdependingonambient
temperature.Afterthepumprunsforapproximatelyoneminute,check
thesightglassforthecorrectoillevel—theoilshouldbeevenwiththe
sightglassOILLEVELline.Addoilifnecessary.
 Note:Whenthepumpisrunning,theoillevelshouldbeevenwith
thelineonthesightglass.Underllingwillresultinpoorvacuum
performance;overllingcanresultinoilblowingfromtheexhaust.
 Yourpumpisnowreadytoevacuateairconditioningandrefrigeration
systems.FollownormalserviceproceduresandtheA/C-R
manufacturer’sinstructionsforconnectionstothesystem.
CAUTION Before connecting your vacuum pump to an A/C-R system,
remove refrigerant from the system in an accepted manner.
Damage to the pump may occur if evacuation is started while
the system is under high pressure. Robinair recommends the
use of our Refrigerant Recovery and Recycling equipment.
