Safety Precautions

ALLOW ONLY QUALIFIED PERSONNEL TO OPERATE THE MACHINE. Beforeoperatingthemachine,

readandfollowtheinstructionsandwarningsinthismanual.Theoperatormustbefamiliarwithair

conditioningandrefrigerationsystems,refrigerants,andthedangersofpressurizedcomponents.Ifthe

operatorcannotreadthismanual,operatinginstructionsandsafetyprecautionsmustbereadanddiscussed

intheoperator’snativelanguage.

USE THE MACHINE AS OUTLINED IN THIS MANUAL.Usingthemachineinamannerforwhichitwas

notdesignedwillcompromisethemachineandnullifytheprotectionsprovided.

PRESSURIZED TANK CONTAINS LIQUID REFRIGERANT.Donotoverlltheinternalstoragevessel(ISV),

becauseoverllingmaycauseexplosionresultinginpersonalinjuryordeath.Donotrecoverrefrigerants

intononrellablecontainers;useonlytype-approvedrellablecontainersthathavepressurereliefvalves.

HOSES MAY CONTAIN LIQUID REFRIGERANT UNDER PRESSURE. Contactwithrefrigerantmay

causepersonalinjury,includingblindnessandfrozenskin.Wearprotectiveequipment,including

gogglesandgloves.Disconnecthosesusingextremecaution.Ensurethephasehasbeencompleted

beforedisconnectingthemachinetopreventthereleaseofrefrigerationtotheatmosphere.

AVOID BREATHING A/C REFRIGERANT AND LUBRICANT VAPOR OR MIST.Exposuremayirritateeyes,

nose,andthroat.ToremoverefrigerantfromtheA/Csystem,useonlyequipmentcertiedforthetypeof

refrigerantbeingremoved.Usetheunitinlocationswithmechanicalventilationthatprovidesatleastfourair

changesperhour.Ifaccidentalsystemdischargeoccurs,ventilatetheworkareabeforeresumingservice.

DO NOT DISPERSE REFRIGERANT INTO THE ENVIRONMENT.Suchaprecautionisnecessarytoprevent

thepossiblepresenceofrefrigerantintheworkingenvironment.

TO REDUCE THE RISK OF FIRE,donotusethemachineinthevicinityofspilledoropencontainersof

gasolineorotherammablesubstances.

TO REDUCE THE RISK OF FIRE, donotuseanextensioncord. Anextensioncordmayoverheatandcause

re.Ifyoumustuseanextensioncord,usetheshortestpossiblecordwithaminimumsizeof14AWG.

TO REDUCE THE RISK OF FIRE,donotusethemachineinthevicinityofamesandhotsurfaces.

Refrigerantcandecomposeathightemperaturesandcanfreetoxicsubstancestotheenvironmentwhich

canbenoxioustotheuser.

TO REDUCE THE RISK OF FIRE,donotusethemachineinenvironmentscontainingexplosivegasesor

vapors.

TO REDUCE THE RISK OF FIRE,protectthemachinefromconditionsthatmaycauseelectricalfailureor

otherhazardsrelatingtoambientinteraction.

CAUTION—DO NOT PRESSURE TEST OR LEAK TEST EQUIPMENT AND / OR VEHICLE AIR CON-

DITIONING SYSTEMS WITH COMPRESSED AIR.Somemixturesofairandrefrigeranthavebeenshown

tobecombustibleatelevatedpressures.Thesemixtures,ifignited,maycauseinjuryorpropertydamage.

HIGH VOLTAGE ELECTRICITY INSIDE THE MACHINE HAS A RISK OF ELECTRICAL SHOCK. Exposure

maycausepersonalinjury.Disconnectpowerbeforeservicingthemachine.

NEVER LEAVE THE MACHINE LIVE IF AN IMMEDIATE USE IS NOT SCHEDULED.Disconnectthe

electricalsupplybeforealongperiodofinactivityorbeforeinternalmaintenanceisperformed.

DO NOT MODIFY THE PRESSURE RELIEF VALVE OR CHANGE THE CONTROL SYSTEM SETTINGS.

Usingthemachineinamannerforwhichitwasnotdesignedwillcompromisethemachineandnullifythe

protectionsprovided.

WARNING : To prevent personal injury,

Additional health and safety information may be obtained

from refrigerant and lubricant manufacturers.

CAUTION : To prevent equipment damage,

Protective devices

Themachineisequippedwiththefollowingprotectivedevices:

• Overpressurevalves.

• Amaximumpressureswitchstopsthecompressorwhenexcessivepressureissensed.

WARNING: Tampering with these protective devices could result in serious injury.

TO PREVENT CROSS-CONTAMINATION, USE THIS MACHINE WITH R1234YF REFRIGERANT ONLY.

Themachineisequippedwithspecialconnectorstorecover,recycle,andrechargeonlyR1234yfrefrigerant.

Donotattempttoadaptthemachineforanotherrefrigerant.Donotmixrefrigeranttypesthroughasystem

orinthesamecontainer;mixingofrefrigerantswillcauseseveredamagetothemachineandthevehicle

airconditioningsystem.

DO NOT USE THIS MACHINE IN DIRECT SUNLIGHT. Positionthemachinefarfromheatsources,suchas

directsunlight,whichcancauseexcessivetemperatures.Theuseofthismachineundernormalenvironmental

conditions(10°Cto50°C)keepspressuresunderreasonablelimits.

DO NOT USE THIS MACHINE OUTDOORS DURING RAIN OR HIGH HUMIDITY. Protectthemachinefrom

conditionsthatmaycauseelectricalfailureorotherhazardsrelatingtoambientinteraction.

DO NOT USE THIS MACHINE IN AREAS WHERE THERE IS A RISK OF EXPLOSION.

SET UP THE MACHINE ON AN EVEN SURFACE AND UNDER SUFFICIENT LIGHTING. LOCK THE

FRONT WHEELS, AND DO NOT SUBJECT THE MACHINE TO VIBRATION.

Safety Precautions

Additional health and safety information may be obtained

from refrigerant and lubricant manufacturers.

System Flushing Process

Thismachineprovidesamethodofremovingoilby

forcingliquidrefrigerantthroughanA/Csystem,or

componentsofanA/Csystem.Aspecialushing

adapter(purchasedseparately)accessestheA/C

systematthecompressorblock.Afterushing,the

refrigerantisrecoveredbythemachineandlteredby

therecyclingcircuit,returningittoSAEpuritylevels.

A/Csystemsvaryandmayrequiretheadaptingand

ushingofindividualcomponents.Refertoservice

bulletinsasneededduringthisprocedure.

Notes:

•

The machine must have at least 4.5 kg (10 lbs.) of

refrigerant available in the ISV (as indicated on the

display) for charging.

•

If the ush process is interrupted by an accidental

power-down or other fault, use the Recovery mode

to remove the refrigerant from the vehicle.

Setup

1.Verifytheoildrainbottleonthefrontofthemachine

isempty.SeeFigure10.Recoverrefrigerantas

outlinedinthismanualunderRecover Refrigerant

2.Closeservicecouplervalvesanddisconnecthoses

fromvehicleaccessports.

3.Closethevalveontheexternalsourcetank.

Note: During this procedure, up to

4.5 kg (10 lbs.)

of refrigerant is charged into the vehicle A/C system.

If the ushing cycle is stopped before it is complete

and the external source valve is open, the machine

automatically adds refrigerant to the ISV, and there will

be no room to recover the refrigerant used for ushing.

4.RemovetheA/Csystemexpansiondevice,and

reconnectthettingstocreateabypass.

5.Disconnectthecompressorblockattherearofthe

The Robinair unit is designed to meet all applicable agency certications, including Underwriter's Laboratories, Inc., SAE Standards,

and CUL. Certain state and local jurisdictions dictate that using this equipment to sell refrigerant by weight may not be permitted.

We recommend charging for any A/C service by the job performed. This weight scale provides a means of metering the amount of

refrigerant needed for optimum A/C system performance as recommended by OEM manufacturers.

La unidad Robinair está diseñada para cumplir con todas las certicaciones de agencia aplicables, incluyendo Underwriter's Laboratories,

Inc., Estándares SAE y CUL. Ciertas jurisdicciones estatales y locales prescriben que el uso de este equipo para vender refrigerante

por peso es posible que no sea permitido. Recomendamos que se cobre el trabajo realizado por dar servicio al aire acondicionado.

Esta escala de peso proporciona un medio para medir la cantidad de refrigerante que se necesita para el rendimiento óptimo del

sistema de aire acondicionado, tal como lo recomiendan los fabricantes OEM.

La machine Robinair a été conçue pour répondre à toutes les certications applicables, y compris celles de l’organisation Underwriters

Laboratories, Inc., ainsi qu’aux normes SAE et CUL. Certaines juridictions nationales et locales n’autorisent pas l’utilisation de cet
