isrequiredpriortore-useof
reclaimedrefrigerant.Itis
essentialthatelectricalpower
isavailablebeforethetaskis
commenced.
• Becomefamiliarwith
theequipmentandits
operation.
• Isolatesystemelectrically.
• Beforeattemptingthe
procedureensurethat:
-mechanicalhandling
equipmentisavailable,
ifrequired,forhandling
refrigerantcylinders;
-allpersonalprotective
equipmentisavailable
andbeingusedcorrectly;
-therecoveryprocessis
supervisedatalltimesby
acompetentperson;
-recoveryequipmentand
cylindersconformtothe
appropriatestandards.
• Pumpdownrefrigerant
system,ifpossible.
• Ifavacuumisnotpossible,
makeamanifoldsothat
refrigerantcanberemoved
fromvariouspartsofthe
system.
• Makesurethatcylinder
issituatedonthescales
beforerecoverytakes
place.
• Starttherecoverymachine
andoperateinaccordance
withmanufacturer’s
instructions.
• Donotoverllcylinders.
(Nomorethan80%

eventemporarily.
• Whenthecylinders
havebeenlled
correctlyandtheproces
completed,makesure
thatthecylindersandthe
equipmentareremoved
fromsitepromptlyand
allisolationvalvesonthe
equipmentareclosedoff.
• Recoveredrefrigerant
shallnotbecharged
intoanotherrefrigeration
systemunlessithasbeen
cleanedandchecked.
• Equipmentshallbelabelled
statingthatithasbeende-

shallbedatedandsigned.
Ensurethattherearelabels
ontheequipmentstating
theequipmentcontains
