Safety Information
• Make sure that the work area is safe from flammable
substances.
• To purge air in the refrigerant, be sure to use a vacuum
pump which is compatible with R-32.
• Note that the refrigerant has no odour.
• The units are not explosion proof so they must be
installed with no risk of explosion.
• This product contains fluorinated gases that contribute
to global greenhouse effect. Accordingly, do not vent
gases into the atmosphere.
• For installation with handling the refrigerant(R-32), use
dedicated tools and piping materials. Working pressure
of R-32 is higher than R410A, So failure to use the
dedicated tools and piping materials may cause rupture
or injury. Furthermore, it may cause serious accidents
such as water leakage, electric shock or fire.
• Servicing shall be performed as recommended by the
manufacturer. In case other skilled persons are joined
for servicing, it shall be carried out under supervision
of the person who is competent in handling flammable
refrigerants.
• For servicing the units containing flammable
refrigerants, safety checks are required to minimise the
risk of ignition. R-32 is slightly more flammable than
R410A hence additional precautions are required when
dealing with it.
• Servicing shall be performed following the controlled
procedure to minimize the risk of flammable
refrigerant or gases.
• Do not install where there is a risk of combustible gas
leakage.
• Do not place heat sources.
• Be cautious not to generate a spark as follows:
– Do not remove the fuses with power on.
– Do not disconnect the power plug from the wall
outlet with power on.
– It is recommended to locate the outlet in a high
position. Place the cords so that they are not
tangled.
• If the indoor unit is not R-32 compatible, an error signal
appears and the unit will not operate.
• After installation, check for leakage. Toxic gas may be
generated and if it comes into contact with an ignition
source such as fan heater, stove, and cooker, cylinders,
make sure that only the refrigerant recovery cylinders
are used.
• Never directly touch any accidental leaking refrigerant.
It could result in severe wounds caused by frostbite.
Power supply line, fuse or circuit breaker
WARNING
• Always make sure that the power supply is compliant
with current safety standards. Always install the air
conditioner in compliance with current local safety
standards.
• Always verify that a suitable earthing connection is
available.
• Verify that the voltage and frequency of the power
supply comply with the specifications and that the
installed power is sufficient to ensure the operation of
any other domestic appliance connected to the same
electric lines.
• Always verify that the cut-off and protection switches
are suitably dimensioned.
• Verify that the air conditioner is connected to the power
supply in accordance with the instructions provided in
the wiring diagram included in the manual.
• Always verify that electric connections (cable entry,
section of leads, protections…) are compliant with
the electric specifications and with the instructions
provided in the wiring scheme. Always verify that all
connections comply with the standards applicable to
the installation of air conditioners.
• Devices disconnected from the power supply should
be completely disconnected in the condition of
overvoltage category.
• Be sure not to perform power cable modification,
extension wiring, and multiple wire connection.
– It may cause electric shock or fire due to poor
connection, poor insulation, or current limit
override.
– When extension wiring is required due to power
line damage, refer to Step 5 Optional: Extending
the power cable in the installation manual.
