Protective zone
The product contains R290 refrigerant. Note that this refri-
gerant has a higher density than air. In the event of a leak,
escaping refrigerant may collect near the ground.
The refrigerant must not collect in any way that may lead
to a dangerous, explosive, suffocating or toxic atmosphere.
The refrigerant must not get inside the building via building
openings. The refrigerant must not collect in grooves.
A protective zone is defined around the product. There must
be no windows, doors, light shafts, cellar entrances, escape
hatches, flat-roof windows or ventilation openings in the pro-
tective zone.
There must be no ignition sources, such as 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.
In the protective zone, you are not permitted to make any
subsequent structural alterations which infringe the stated
rules for the protective zone.
