4.3.3 Refrigerant analyzer lter / ow restrictor replacement (NEUTRONICS original spare parts)
NOTE: Always use goggles and gloves!
Contact with the refrigerant can cause blindness and other physical injury to
the user!
IMPORTANT: Disconnect the plug from the power supply!
AccordingtoNeutronicsspecication:
Wheninspectingthesamplelter,lookcompletelyaroundtheentireoutsidediameterofthewhitelterele-
ment located inside of the clear plastic housing.
Look for red spots or the beginnings of discoloration on the white outside diameter of the element. Do not
look into the round ends of the white element for red spots or discoloration.
Theroundendsoftheltermayalwaysappearred.Ifredspotsordiscolorationsarediscovered,thesample
lterrequiresreplacementtopreventtheinuxofparticulateandoilmistsintotheinstrument.
Removetheexistinglterfromtheretainingclipoftheinstrumentbypullingstraightupandout.
Carefullyremovetheexible,blackrubbertubingconnectionsfrombothendsoftheexistinglter.
Do not allow the tubes to slip back into the internal portion of the case.
Installthetubeendsontothebarbsofthereplacementlter,takingnotetoaligntheowarrowofthelter
withtheowarrowonthemountingbezeloftheanalyzer.
Carefullyslidethetubingbackintotheinternalportionoftheinstrumentandseatthenewlterintothe
retaining clip.
Removetheowrestrictorbyunscrewingthebrassele-
ment highlighted in g.004“Flowrestrictorconnection”
and then disconnect the other side of the transparent
hose from the port on the one way manifold.
Install the free end of the transparent hose and the
brasselementofthereplacementowrestrictoras
shown in the picture. Check the connection of the trans-
parent tube end in order to prevent it from sliding out.
Inspect the transparent hose that connects the one way
manifoldtotheanalyzer.IfevidencesofoilorUVtracer
arefoundinsidethetube,thenitisnecessarytoreplace
it. Check the connection of the transparent tube end in
order to prevent it from sliding out.
IMPORTANT: Dispose according to local
regulations.
