▪ In case of an installation site where sides A+B+C+D have
obstacles, the wall heights of sides A+C have no impact on
service space dimensions. Refer to the figure above for impact of
wall heights of sides B+D on service space dimensions.
▪ In case of an installation site where only the sides A+B have
obstacles, the wall heights have no influence on any indicated
service space dimensions.
▪ The installation space required on these drawings are for full load
heating operation without considering possible ice accumulation. If
the location of the installation is in a cold climate, then all
dimensions above should be >500 mm to avoid accumulation of
ice in between the outdoor units.
INFORMATION
The service space dimensions in above figure are based
on cooling operation at 35°C ambient temperature
(standard conditions).
INFORMATION
Further specifications can be found in the technical
engineering data.
