Appropriaterefrigerant
Therefrigerantusedineachunitisidentiedonthespecicationlabelandmanualsoftheunit.Hitachishallnotbeheld
liableforanyfailure,trouble,malfunctionoraccidentcausedbyunitsillegallychargedwithrefrigerantsotherthanthe
speciedone.
Consequencesofchargingnon-speciedrefrigerant
Itmaycausemechanicalfailure,malfunctionandotheraccidents.
Itmaycauseoperationalfailureofprotectionandsafetydevicesofairconditioners.
Itmayalsocauselubricationfailureoftheslidingpartofthecompressorduetodeteriorationofrefrigerantoil.
Inparticular,hydrocarbonrefrigerants(suchaspropane,R441A,R443A,GF-08,etc.)arenotallowed,sincetheseare
combustibleandmaycausemajoraccidentssuchasreandexplosionincaseofimproperhandling.
Onceanon-speciedrefrigeranthasbeencharged,nofurtherservicing(includingdrainingofrefrigerant)shallbe
performed,evenincaseofmalfunction.Improperhandlingofrefrigerantmaybeacauseofreandexplosion,and
servicinginsuchcasesmaybeconsideredanillegalact.
Endclientsandcostumersshallbeinformedthatservicingisnotapproved,andtheinstallerwhochargedthe
nonspeciedrefrigerantshallbeaskedtoxtheunit.
Hitachiwillacceptnoresponsibilityforunitsthathavebeenchargedwithnon-speciedrefrigerantonce.
