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

machine.

4. Whenthescalestopsrisingcloseallports

5. Switchoffthemachine.



CAUTION:

WhenusingthePush/pullmethod,ascalemustbeusedtoavoidover

fillingthestoragetank,oncethesiphonisstarted,itcancontinueand

overfillthestoragetankevenifthetankisequippedwithafloat

levelsensor.Thesiphoncancontinueevenwhenthemachineis
