•
 Donotinstalltheindoorunitinamachineryshop
orkitchenwherevaporfromoiloritsmistows
totheindoorunit.
Anoilwilldepositontheheatexchanger,
therebyreducingtheindoorunitperformance
andtheplasticpartsmaydeform,andinthe
worstcase,breakduetosplashoilatoperation.
•
 Avoidtheinstallationplacewheretheindoorunit
maycontacthighhumidity.
•
 Thewarmedairmaystayatthehighceiling
spaceduringtheheatingoperation.Thus,the
parallelinstallingofacirculatorisrecommended.
•
 Theindoorunitcanbeinstalledupto3.5meters
(for1.5to3HP)and4.3meters(for4to6HP)
fromtheoorlevel.

 Avoidinstallingtheairconditioningwherethe
directairowblowsfromtheairoutlettothe
temperaturedetectingdevicessuchanalarm
deviceoracontroldevice.Itmaycauseafailure

Make sure that a refrigerant leak test has
been performed. Refrigerant (Fluorocarbon
or Diuoromethane) for this unit is non-
toxic, and odorless. If the refrigerant should
somehow escape and come into contact with
ame, toxic gas will form. This gas is heavier
than air and will settle near oor areas and
spread where it can cause su󰀨ocation to
those nearby. In addition, diuoromethane is
ammable and can cause re.
