• When work is performed at heights, use a ladder which complies with
the ISO 14122 standard, and follow the procedure in the ladder’s
instructions. Also wear a helmet for use in industry as protective gear
to undertake the work.
• This unit is equipped with a refrigerant leak detection sensor for
safety, to be effective, the unit must be electrically powered at all
times after installation, other than when servicing. Turning off the
circuit breaker cause refrigerant leak detection sensor not to operate
and not to enable to detect refrigerant leaks, causing a fire.
• Do not use the refrigerant other than R32 or R410A. For the
refrigerant type, check the outdoor unit to be combined.
• The air conditioner must be transported in stable condition. If any part
of the product is broken, contact the dealer.
• When the air conditioner must be transported by hand, carry it by four
or more people.
• Servicing shall be performed only as recommended by the
manufacturer. Do not move or repair any unit by yourself. There is
high voltage inside the unit. You may get electric shock when
removing the cover and main unit.
• This appliance is intended to be used by expert or trained users in
shops, in light industry, or for commercial use by lay persons.
About the refrigerant R32
• The appliance shall be stored in a room without continuously
operating ignition sources (for example: open flames, an operating
gas appliance or an operating electric heater).
• Do not pierce or burn refrigerant cycle parts.
• Do not use means to accelerate the defrosting process or to clean,
other than those recommended by the manufacturer.
• Be aware that refrigerants may not contain an odor.
• Pipe-work shall be protected from physical damage.
• Compliance with national gas regulations shall be observed.
• If refrigerant leak detection sensor detects R32 refrigerant leak, a fan
on indoor unit automatically operates to stir an air in the room. Stirring
air flow volume of each model is as shown below.
Selection of installation location
• When the air conditioner is installed in a small room, provide
appropriate measures to ensure that the concentration of refrigerant
leakage occur in the room does not exceed the critical level.
• Do not install in a location where flammable gas leaks are possible. If
the gas leak and accumulate around the unit, it may ignite and cause
a fire.
• To transport the air conditioner, wear shoes with additional protective
toecap.
• To transport the air conditioner, do not take hold of the bands around
the packing carton. You may injure yourself if the bands should break.
• Do not place any combustion appliance in a place where it is directly
exposed to the wind of air conditioner, otherwise it may cause
imperfect combustion.
• When an outdoor unit using R32 refrigerant is combined with indoor
unit, be attention to the floor area in the room to be installed. The unit
cannot be installed in the room with floor area less than minimum floor
area described in Appendix of this Installation Manual.
