• Do not use any refrigerant different from the one speci
fi
ed for complement or
replacement.
Otherwise, abnormally high pressure may be generated in the refrigeration
cycle, which may result in a failure or explosion of the product or an injury to
your body.
• Do not use means to accelerate the defrosting process or to clean, other than
those recommended by the manufacturer.
• The appliance shall be stored in a room without continuously operating ignition
sources (for example: open
fl
ames, an operating gas appliance or an operating
electric heater).
• Be aware that refrigerants may not contain an odour.
• Do not pierce or burn as the appliance is pressurized. Do not expose the
appliance to heat,
fl
ame, sparks, or other sources or ignition. Else, it may
explode and cause injury or death.
• For R32 model, use pipes,
fl
are nut and tools which is speci
fi
ed for R32
refrigerant. Using of existing (R22) piping,
fl
are nut and tools may cause
abnormally high pressure in the refrigerant cycle (piping), and possibly result in
explosion and injury.
• Thickness of copper pipes used R32 must be more than 0.8mm. Never use
copper pipes thinner than 0.8mm.
• Do not perform
fl
are connection inside a building or dwelling or room, when
joining the heat exchanger of indoor unit with interconnection piping. Refrigerant
connection inside a building or dwelling or room must be made by brazing or
welding. Joint connection of indoor unit by
fl
aring method can only be made
at outdoor or at outside of building or dwelling or room. Flare connection may
cause gas leak and
fl
ammable atmosphere.
• After completion of installation or service, con
fi
rm there is no leakage of
refrigerant gas. It may generate toxic gas when the refrigerant contacts with
fi
re.
• Appliance and pipe-work shall be installed, operated and stored in a room with a
