charging.
The total refrigerant charge in the system is ≤1.842 kg, so the
system is NOT subjected to any requirements to the installation
room. However, mind the following requirements and precautions:
WARNING
▪ Do NOT pierce or burn refrigerant cycle parts.
▪ Do NOT use means to accelerate the defrosting
process or to clean the equipment, other than those
recommended by the manufacturer.
▪ Be aware that R32 refrigerant does NOT contain an

The appliance shall be stored so as to prevent mechanical
damage and in a well-ventilated room without continuously
operating ignition sources (example: open flames, an
operating gas appliance or an operating electric heater).
