01 PREPARATION
Servicing shall be performed following the controlled procedure to minimize the risk of ammable 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 re extinguisher
If a hot work is to be done, an appropriate re extinguishing equipment should have been available.
A dry powder or CO re 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 ames, an
operating gas appliance or an operating electric heater).
The service engineers shall not use any ignition sources with the risk of re or explosion.
Potential ignition sources shall be kept away from the work area where the ammable refrigerant can possibly be
released to the surrounding.
The work area should be checked to ensure that there are no ammable 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 ammable atmosphere. Other parts may result in ignition
due to leakage.
Replace components only with parts specied 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.
