This outdoor unit is filled with R290(Extremely flammable gas, safety A3 group per ISO 817). Note that this refrigerant has a higher density
than air. In case of a refrigerant leak, the leaked refrigerant may accumulate near the ground.
Prevent accumulation of refrigerant in any way that is potentially dangerous, explosive or risk suffocation. Prevent refrigerant from entering
the building through building openings. Prevent accumulation of refrigerant in the drain grooves.
A protective zone is defined around this outdoor unit. There must be no building openings, windows, doors, light shafts, cellar entrances,
escape hatches, flat-roof windows or ventilation openings in the protective zone.
There must be no ignition sources, such as heat above
360°C
, sparks, open flame, plug sockets, light switches, lamps, electrical switches or
other permanent ignitions sources, in the protective zone.
The protective zone must not extend to adjacent buildings or public traffic areas (boundaries of neighbors, the public road, neighbor's private
roads, subsidence area, depressions, pump shafts, sewers intakes, waste water shafts and so on.).
In the protective zone, you are not permitted to make any subsequent structural alterations which infringe the stated rules for the protective
