Safety Information

• 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.

Preparation of fire extinguisher

• If a hot work is to be done, an appropriate fire

extinguishing equipment should have been available.

• A dry powder or CO₂ fire extinguisher shall be 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.

Leakage detection methods

• 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, naked flames shall be removed.

• 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.
