WARNING
For units using the R32 refrigerant it is necessary to keep
any required ventilation openings and chimneys clear of
obstructions.
Depending on the type of room in which you install the indoor unit, different installation patterns are allowed:
Room type Allowed patterns
Living room, kitchen, garage, attic, basement, storage room 1, 2, 3
Technical room (i.e. room that is NEVER occupied by persons) 1, 2, 3, 4

a If no chimney is installed, this is the default point of release
in case of refrigerant leakage.
If needed, you can connect a chimney here:
▪ Unit's connection point for the chimney = 1" male thread.
Use a compatible counterpart for the chimney.
▪ Make sure the connection is airtight.

Installation with chimney connected to the outside. The
release height is not relevant. There are no requirements to
the minimum floor area.
N/A Not applicable
Minimum floor area / Release height:
▪ The minimum floor area requirements depend on the release
height of the refrigerant in case of a leakage. The higher the
release height, the lower the minimum floor area requirements.
▪ The default point of release (without chimney) is at the top of the
unit. To decrease the minimum floor area requirements, you can
increase the release height by installing a chimney. If the chimney
leads outside of the building, there are no requirements anymore
to the minimum floor area.
▪ You can also take advantage of the floor area of the adjacent
room (= room B) by providing ventilation openings between the
two rooms.
▪ For installations in technical rooms (i.e. room that is NEVER
occupied by persons), additionally to patterns 1, 2 and 3, you can
also use PATTERN4. For this pattern there are no requirements
to the minimum floor area if you provide 2 openings (one at the
bottom, one at the top) between the room and the outside to
ensure natural ventilation. The room must be protected from frost.
When connecting a chimney
▪ Install the chimney socket (delivered as accessory) to the plate
heat exchanger box.
