• After completing the installation, always carry out a functional test (commissioning, including reporting) and provide
instructions on how to operate the air to water heat pump to the user.
• Do not use the air to water heat pump in environments with hazardous substances or close to equipment that releases
open flames to avoid the occurrence of fires, explosions or injuries.
• While in installation or relocation of the product, do not mix 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 clean parts such as the manifold gauge, vacuum pump, and charging hose of the R32 refrigerant.
• 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 R32, water, etc.) enter the refrigerant circuit.
• When mechanical ventilation is required, ventilation openings shall be kept clear of obstruction.
• For disposal of the product, follow the local laws and regulations.
• Do not work in a confined place.
• The work area shall be blocked.
• The following checks shall be performed for installation:
–The ventilation devices and outlets are operating normally and are not obstructed.
–Markings and signs on the equipment shall be visible and legible.
• Upon leakage of the refrigerant, ventilate the room. When the leaked refrigerant is exposed to a flame or hot source, it
may cause the generation of toxic gases.
• Make sure that the work area is safe from flammable substances.
• To purge air in the refrigerant piping, 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.

1.3 Caution of Ignition sources
• If brazing or welding work is required, appropriate fire extinguishing equipment should be available.
• 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.
• Replace components only with parts specified by Samsung. Other parts may result in the ignition of refrigerant in the
atmosphere from a leak.
• 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.
1.4 Leakage detection and refrigerant recovery
• The leakage detector shall be calibrated in a refrigerant-free area.
• Make sure that the detector is not a potential source of ignition.
• The leakage detector shall be set to the LFL (lower flammability limit).
• The use of detergents containing chlorine shall be avoided for cleaning because the chlorine may react with the
refrigerant and corrode the pipings.
• If leakage is suspected, open flames must be extinguished immediately.
• If a leakage is found while in brazing, the entire refrigerant shall be recovered from the product or isolated (e.g. using
shut-off valves). It shall not be directly released to the environment. Oxygen free nitrogen (OFN) shall be used for
purging the system before and during the brazing process.
• The work area shall be checked with an appropriate refrigerant detector before and during work.
• Ensure that the leakage detector is appropriate for use with flammable refrigerants.
