• For installation with handling the refrigerant(R-32),
use dedicated tools and piping materials.
• Servicing and installation 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.
• This could result in severe wounds caused by
frostbite.
Preparation of fire extinguisher
• If a hot work is to be done, an appropriate fire
extinguishing equipment should have been available.
•
equipped near the charging area.
Ignition sources free
• Make sure to store the units in a place without
continuously operating ignition sources (for example,
open flames, an operating gas appliance or an
operating electric heater).
• The service engineers shall not use any ignition
sources with the risk of fire or explosion.
• Potential ignition sources shall be kept away from
the work area where the flammable refrigerant can
possibly be released to the surrounding.
• The work area should be checked to ensure that
there are no flammable hazards or ignition risks. The
"No Smoking" sign shall be attached.
• Under no circumstances shall potential sources of
ignition be used while in detection of leakage.
• Make sure that the seals or sealing materials have
not degraded.
• Safe parts are the ones with which the worker can
work in a flammable atmosphere. Other parts may
result in ignition due to leakage.
• Replace components only with parts specified by
Samsung. Other parts may result in the ignition of
refrigerant in the atmosphere from a leak.
Area ventilation
• Make sure that the work area is well ventilated
before performing a hot work.
• Ventilation shall be made even during the work.
• The ventilation should safely disperse any
released gases and preferably expel them into the
atmosphere.
• Ventilation shall be made even during the work.
