▪ 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 odour.
WARNING
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).
WARNING
Make sure installation, servicing, maintenance and repair comply with instructions
from Daikin and with applicable legislation (for example national gas regulation) and
are executed only by authorised persons.
