▪ 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.
WARNING
Chimney connection. When connecting a chimney, take the following into account:
▪ Unit's connection point for the chimney = 1" male thread. Use a compatible
counterpart for the chimney.
▪ Make sure the connection is airtight.
▪ The chimney material is unimportant.
