the refrigerant with other gases including air or unspecified
refrigerant. Failure to do so may cause pressure increase
resulting in an explosion, rupture or injury.
• Do not cut or burn the refrigerant container or pipings.
• Use only suitable and clean service equipment such as the
manifold gauge, vacuum pump, and charging hose of the
R-290 refrigerant. Make sure that any pump and leakage
detection device must be suitable for safely working with
R-290 refrigerant.
WARNING
• Failing to do so, may result in fire, explosion, property
damage, personal injury or death.
• Installation must be carried out by qualified persons to handle
the refrigerant. Additionally, refer to the regulations and laws.
• Be careful not to let foreign substances (lubricating oil, refrigerant
other than R-290, water, etc.) enter the refrigerant circuit.
• Products should be installed outdoors with natural ventilation.
• For disposal of the product, follow the local laws and regulations.
(Please refer to the reference guide for details.)
• Do not work in a confined or unvented place.
• The work area must be surveyed and inspected prior to any
service work, correctly vented and treated always as if the
equipment is leaking. The area around the working space must
be sectioned off properly.
• The product and the hydraulic system shall be installed in
the position where there are no substances that may result in
corrosion.
• The following checks shall be performed for installation:
– There must be a suitable gas detector to look for
refrigerant leaks.
– Notify all workers of work contents.
– Install “No smoking” and “Do not enter the area” signs.
– Receive a work permit from manager and work.
– Do not store flammable materials in the workplace.
– There should be no sources of ignition anywhere in the
workplace.
– Appropriate fire extinguishing equipment (CO2 or dry-
powder type) should be located nearby and conveniently
located.
– The refrigerant discharged must be sufficiently dispersed
and ventilated.
– The work area should be appropriately ventilated before
working on the refrigerant circuit, brazing, or handling
electrics.
• To purge air in the refrigerant piping, be sure to use a vacuum
pump suitable for handling R-290.
• Note that the refrigerant has no odour.
• The units are not explosion proof so they must be installed
with no risk of explosion.
• For installation with handling the refrigerant (R-290), 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.
• Safety checks are required to minimize the ignition risk for
servicing the units containing flammable refrigerants.
• Servicing shall be performed following the controlled
procedure to minimize the risk of flammable refrigerant or
gases.
• Do not install the unit where there is a risk of combustible gas
leakage.
• Do not place the unit near heat sources.
• Be cautious not to generate a spark as follows:
– Do not remove the fuses with power on.
• If the indoor unit is not R-290 compatible, an error signal
appears and the unit will not operate.
• After installation, check for leakage. Toxic gas may be
generated if it comes into contact with an ignition source such
as the fan heater, stove, and cooker.
• In order to service the product, collect the refrigerant in
vacuumed recovery cylinders.
• Never directly touch any accidental leaking refrigerant. This
could result in severe wounds caused by frostbite.
Caution of Ignition sources
• Appropriate fire extinguishing equipment should always be
available during any type of hot work.
• A dry powder or CO₂ fire extinguisher must be available
near the charging area. Please comply with local rules and
regulations regarding working with open flames. Always
respect waiting times and requirements regarding the type
and quantity of the extinguishing equipment.
• 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 the 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. In the case of electric components
replacement, care should be taken to ensure that electrical
terminals, including capacitor terminals, are adequately
tightened and secured against loosening and that adequate
insulation is provided to avoid live parts shorting together.
• Make sure that the work area is well ventilated before
performing a hot work.
• Ventilation of the installation areas must be maintained during
the work.
• The ventilation should safely disperse any released gases and
preferably expel them into the atmosphere.
