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.

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.
12.3 Service space: Indoor unit
Make sure the space around the unit is adequate for servicing (refer
to the figure below).
CAUTION
Make sure the right service panel can still be removed after
installation of the piping.
