Safety Precautions for Refrigerant ●To realize the function of the air conditioner unit, a special refrigerant circulates in the system. The used refrigerant is the fluoride R32,which is specially cleaned. The refrigerant is flammable and inodorous. Furthermore, it can leads to explosion under certain conditions. But the flammability of the refrigerant is very low. It can be ignited only by fire. ●Compared to common refrigerants, R32 is a nonpolluting refrigerant with no harm to the ozonosphere. The influence upon the greenhouse effect is also lower. R32 has got very good thermodynamic features which lead to a really high energy efficiency. The units therefore need a less filling. WARNING: ●Do not use means to accelerate the defrosting process or to clean, other than those recommended by the manufacture. Should repair be necessary,contact your nearest authorized Service Centre. Any repairs carried out by unqualified personnel may be dangerous. The appliance shall be stored in a room without continuously operating ignition sources. (for example:open flames , an operating gas appliance or an operating electric heater.) ●Do not pierce or burn. ●Appliance shall be installed, operated and stored in a room with a floor area larger than 4m 2 (or 6m 2 ). ●Appliance filled with flammable gas R32. For repairs, strictly follow manufacturer’s instructions only.Be aware that refrigrants not contain odour. ●Read specialist’s manual. 29 Installation and Maintenance
