GENERALSAFETYGUIDELINES

1. Readallsafety,operatingguidelinesandinstructionsbeforeoperating
thisrecoverymachine.
2. Alwaysthinkbeforeacting,familiaritybreedscarelessness,and
carelessnesscanbeharmfultoyourhealth,orworse,resultindeath.
3. OnlyaqualifiedtechnicianshouldoperatethisRecoverymachine.
4. Readallsafetyinformationregardingthesafehandlingofrefrigerant
andrefrigerantoil,includingtheMaterialSafetyDataSheet.
MSDSsheetscanbeobtainedfromyourrefrigerantsupplier..
5. Alwayswearsafetygogglesandprotectivegloveswhenworkingwith
refrigerantstoprotectyourskinsandeyesfromrefrigerantgasesand
refrigerantliquid.Avoidgettingintouchwithcausticityliquidorgas.
6. Besurethatanyroomwhereyouareworkingisthoroughlyventilated.
7. UseONLYauthorizedrefillablerefrigeranttanks.Itrequirestheuseof
recoveringtankswithaminimumof27.6barworkingpressure.
8. Donotoverfillthestoragetank.Tankisfullat80%volume.Thereshould
beenoughspaceforliquidexpansion‐overfillingofthetankmaycausea
violentexplosion.
9. DonotexceedtheworkingpressureofRecoveringTankcylinder.
10. Donotmixdifferentrefrigerantstogetherinonetank,ortheycould
notbeseparatedorused.
11. Beforerecoveringtherefrigerant,thetankshouldachievethevacuum
level:‐0.1mpa,whichisforpurgingnon‐condensablegases.
Eachtankwasfullofnitrogenwhenitwasmanufacturedinthefactory,thus
thenitrogenshouldbeevacuatedbeforethefirstuse.
12. Whentherecoverymachineisnotused,allthevalvesshouldbeclosed.
Becausetheairorthemoistureoftheairmayharmtherecoveryresultand
shortentheservicelifeoftherecoverymachine.
13. Whenusinganextensioncord,itshouldbea14AWGminimumandno
longerthan7.62meters(25feet),oritmaymakethevoltagedropanddamage
thecompressor.
14. Adryfiltermustalwaysbeusedandshouldreplacedfrequently.
Andeachtypeofrefrigerantmusthaveitsownfilter.Forthesakeofassuring
thenormaloperationoftheunit,pleaseusethefilterspecifiedbyour
company.Highqualitydryfilterswillbringhighqualityservices
15. Specialcareshouldbetakenwhenrecoveringfromaburned‐out

system.Usetwohighacidcapacityfilters,inseries.Whenyouhave
finishedrecoveringfromthesystem,flushtherecoverymachinewithasmall
amountofcleanrefrigerantandrefrigerantoiltopurgeoffanyforeign
substancesleftinthemachine.
16. ThisrecoverymachinehasaPressureShutOffSwitch.Ifthepressure
insidethesystemshouldgoabove38bars,thesystemwillautomaticallyshut
itselfoff.Theshutoffswitchmustbemanuallyreset.
17. Ifthetankpressureexceeds20.7bar,usetheTANKCOOLING
PROCEDUREtoreducethetankpressure.
18. Tomaximizerecoveryrates,usetheshortestpossiblelengthof3/8”or
largerhose.Ahosenolongerthan0.9meterisrecommended
19. Whenrecoveringlargeamountsofliquid,usetheLIQUIDPUSH
/PULLPROCEDURE.
20. Afterrecovering,makesurethere'snorefrigerantleftinthemachine.
ReadtheSELF‐PURGINGPROCEDUREcarefully.Liquidrefrigerantremained
maybeexpandedanddestroythecomponents.
21. Ifthisrecoverymachineistobestoredornotusedforanylengthof
time,werecommendthatitbecompletelyevacuatedofanyresidual
refrigerantandpurgedwithdrynitrogen.
22. Toreducetheriskofinjury,careshouldbetakenwhenmovingthis

NORMEDISICUREZZAELINEEGUIDAPERL’UTILIZZO

1. Leggereattentamenteilpresentemanualeprimadiutilizzarel’unitàdi
recupero.
2. Pensareprimadiagire,lafamiliaritàgeneraincuriaedisattenzione;può
esseredannosoperlasalute,opeggio,causarelamorte.
3. L’utilizzodell’unitàdirecuperoèdestinatoesclusivamentead
operatoriqualificati.
4. Leggeretutteleinformazionidisicurezzariguardantilamanipolazione
delrefrigeranteel'oliorefrigerante,compresalaSchedadiSicurezza.
Leschededisicurezzapossonoessereottenutepressoilfornitore.
5. Indossaresempreadeguateprotezioni,qualiguantiedocchiali;il
contattoconilrefrigerantepuòprovocarececitàedaltridannifisici.
Evitaredientrareincontattoconliquidoogascaustici.
6. Assicurarsidifarfunzionareilrecuperatoreinambientiadeguatamente
ventilatieconunbuonricambiod’aria.
7. UtilizzareSOLOdellebomboledirefrigerantericaricabiliautorizzatecon
pressionedilavorominimadi27.6bar.
8. Nonriempiretroppolebomboledirecupero.Lebombolesonopiene
all’80%dellalorocapacitàmassima.Unriempimentoeccessivopotrebbe
causareviolentiesplosioni.
9. Nonsuperarelapressionedilavorodellabomboladirecupero.
10. Nonmischiarerefrigerantidiversinellastessabombola.
11. Primadirecuperareilrefrigerate,labomboladeveraggiungereungrado
divuotodi‐0.1mPa,perpoterrimuovereigasnoncondensabiliedeventuale
umidità.
12. Quandol’unitànonvieneutilizzatatuttelevalvoledevonoesserechiuse.
L’ariael’umiditàpossonodanneggiareleprestazionidirecuperoeridurrela
duratadelrecuperatore.
13. Sesiusaunaprolungaelettrica,lasezionedeicavideveesserealmeno
2.0mm2edilcavonondeveesserepiùlungodi7.62m(25feet);ciòpotrebbe
causarel’abbassamentoditensioneedanneggiareilcompressore.
14. Utilizzaresempreunfiltrodeidratoreesostituirlofrequentemente.Ogni
tipodirefrigerantedeveavereilpropriofiltro.Alfinediassicurareinbuon
funzionamentodell’unitàdirecupero,siconsigliadiutilizzarefiltridialta
qualità.
15. Prestaremoltaattenzionequandosirecuperadaunsistemabruciato:

3 IT
utilizzareduefiltriperacidodialtacapacitàinserie.Arecuperoultimato
lavarel’unitàconunapiccolaquantitàdirefrigerantepulitoeconolio
refrigeranteperripuliredasostanzeestraneerimasteall’interno.
16. L’unitàhaundispositivodiarrestoautomaticodialtapressione.Sela
pressioneall’internodelsistemasaleoltre38.5barl’unitàsispegnerà
automaticamente.L’interruttoredovràessereresettatomanualmente.
17. Selapressionedellabombolasuperai20.7bar,seguirelaPROCEDURADI
RAFFREDDAMENTOperridurnelapressione
18. Perottimizzarelavelocitàdirecupero,fareusodiuntuboflessibilepiù
cortopossibile.Lunghezzaraccomandatainferiore0.9m
19. Duranteilrecuperodigradiquantitàdirefrigeranteliquidousarela
proceduraPUSH/PULL.
20. Dopoilrecuperoassicurarsichenoncisiapiùrefrigerantenell’unità.
Leggereattentamentelaproceduradi“SELF‐PURGE”.Sedelrefrigerante
liquidorimanenell’unità,sipuòespandereedanneggiareicomponenti.
21. Inprevisionediunlungoperiododiinattivitàosel’unitàdeveessere
riposta,evacuarel’unitàdaogniresiduodirefrigeranteeripulirlaconazoto
