f
Do not install where there is a risk of combustible gas leakage .
f
f
Do not place heat sources .
f
f
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 .
f
f
If the indoor unit is not R-32 compatible, an error signal appears and the unit will not operate .
f
f
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 .
f
f
Never directly touch any accidental leaking refrigerant .
f
f
This could result in severe wounds caused by frostbite .
Preparation of fire extinguisher
f
f
If a hot work is to be done, an appropriate fire extinguishing equipment should have been available .
f
f
A dry powder or CO₂ fire extinguisher shall be equipped near the charging area .
Ignition sources free
f
f
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) .
f
f
The service engineers shall not use any ignition sources with the risk of fire or explosion .
f
f
Potential ignition sources shall be kept away from the work area where the flammable refrigerant can possibly be
released to the surrounding .
f
f
The work area should be checked to ensure that there are no flammable hazards or ignition risks . The “No Smoking” sign
shall be attached .
f
f
Under no circumstances shall potential sources of ignition be used while in detection of leakage .
f
f
Make sure that the seals or sealing materials have not degraded .
f
f
Safe parts are the ones with which the worker can work in a flammable atmosphere . Other parts may result in ignition
due to leakage .
f
f
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
f
f
Make sure that the work area is well ventilated before performing a hot work .
f
f
Ventilation shall be made even during the work .
f
f
The ventilation should safely disperse any released gases and preferably expel them into the atmosphere .
