Power Supply Line, Fuse Or Circuit Breaker - Samsung AC RXAD G Series Installation Manual

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.
• 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.
• 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.

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 4 Optional: Extending
the power cable in the installation manual.
