• Do not use any refrigerant different from the outdoor unit specifi 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.
• A special tool for the R32 or R410A refrigerant is required for installation.
• Thickness of copper pipes used R32 must be more than 0.8 mm. Never use
copper pipes thinner than 0.8 mm.
• After completion of installation or service, confi rm there is no leakage of
refrigerant gas. It may generate toxic gas when the refrigerant contacts with fi re.
• When the indoor unit is connected with multi-split R32 outdoor unit 3M26, 4M27
and 5M34.
Please see IMS outdoor unit installation manual and consult your dealer about
the minimum fl oor area.
• Comply with national gas regulations.
WARNING
• After installation work, make sure below before operation.
- Connection pipes are connected properly and no leakage.
- Packed valves are fully open.
Running compressor without open packed valves may cause abnormal high
pressure and parts failure.
Leakage at connection piping may suck air and make further high pressure
cause burst and injure.
• During pump down work make sure below process.
- Don't mix air into the refrigerant cycle.
- Stop the compressor before removing piping after packed valves are
fully closed.
Removing piping under the compressor running and packed valves open,
air might be sucked and refrigeration cycle pressure becomes abnormally high,
and it causes burst or injury on persons.
