12.1
Overview: Technical data
This chapter contains information about:
▪ Service space
▪ Piping diagram
▪ Wiring diagram
▪ Field settings
▪ ESP curves
12.2
Service space: Outdoor unit
Make sure the space around the unit is adequate for servicing and
the minimum space for air inlet and air outlet is available (refer to the
figure below and choose one of the possibilities).
▪ 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 for impact of wall
heights of sides B+D on service space dimensions.
▪ In case of an installation site where only sides A+B have
obstacles, the wall heights have no influence on any indicated
service space dimensions.
