2. 1. Precautions for using R410A refrigerant
WARNING
Donotintroduceanysubstanceotherthantheprescribedrefrigerantintotherefrigera-
tioncycle.Ifairenterstherefrigerationcycle,thepressureintherefrigerationcycle

Ifthereisarefrigerantleak,makesurethatitdoesnotexceedtheconcentrationlimit.
Ifarefrigerantleakexceedstheconcentrationlimit,itcanleadtoaccidentssuchas
oxygenstarvation.
Donottouchrefrigerantthathasleakedfromtherefrigerantpipeconnectionsorother
area.Touchingtherefrigerantdirectlycancausefrostbite.
Ifarefrigerantleakoccursduringoperation,immediatelyvacatethepremisesand

andwhichwillnotamplifysoundorvibration.Iftheinstallationlocationisnotstrong
enough,theindoorunitmayfallandcauseinjuries.
Installtheunitssecurelysothattheydonottoppleorfall.
CAUTION
Donotinstalltheindoorunitinthefollowingareas:
• Areawithhighsaltcontent,suchasattheseaside.
Itwilldeterioratemetalparts,causingthepartstofallortheunittoleakwater.
• Arealledwithmineraloilorcontainingalargeamountofsplashedoilorsteam,
