3 SAFETY ZONE
The refrigerant circuit in the outdoor unit contains
easily flammable refrigerant in safety group A3 as
described in ISO 817 and ANSI/ASHRAE Standard
34. Therefore, a safety zone is defined in the
immediate vicinity of the outdoor unit, in which
special requirements apply. Note that this refrigerant
has a higher density than air. In the event of a leak,
escaping refrigerant may be collected near the earth.
The following conditions must be avoided within the
safety zone:
Building openings such as windows, doors, light
wells, and flat roof windows;
Outdoor air and exhaust air apertures of
ventilation and air conditioning systems;
Property boundaries, neighboring properties,
footpaths, and driveways;
Pump shafts, inlets to waste water systems,
downpipes, and waste water shafts, etc.;
Other slopes, troughs, depressions, and shafts;
Electrical house supply connections;
Electrical systems, sockets, lamps, and light
switches; Snowfall from roofs.
Do not introduce ignition sources into the safety zone:
Naked flames or burner gauze assemblies.
Grills.
Tools that generate sparks.
Electrical devices not free of ignition sources,
mobile devices with integrated batteries (such as
mobile phones and fitness watches).
Objects with a temperature of above 360 °C.
NOTE
The particular safety zone is dependent on
the surroundings of the outdoor unit.
The safety zones below are shown with
floor standing installation. These safety zones
also apply to other types of installation.
