Notice on extreme
conditions!
In addition to the air temperature/air humidity of the transported medium, the temper-
ature/humidity of the ambient air is also critical. Environmental factors such as proxim-
ity to sea or ocean must be taken into account when selecting material quality.
Different ambient conditions apply for integrated refrigerating unit.
3.3.2 Permitted storage conditions / permitted air condition for uninstalled units
Air temperature -10 °C to +50 °C
Air humidity Store units in a dry, non-condensing atmosphere
3.3.3 Supply voltage
The required supply voltage is specified in the order-related documentation, e.g. AC
230 V/50 Hz (1 phase) or AC 400 V/50 Hz (3 phases).
3.3.4 Condensation limits
Please pay due attention to condensation limits!
The following diagrams illustrate condensation limits depending on temperature and
relative humidity at the installation site - for series CAIRplus SX M and CAIRplus SX K.
The diagrams are based on normal air values and are calculated using a model box.
The given values are approximate figures and can not be used as a guarantee for
avoiding condensation. Depending on different casing components, deviations are
possible.
Note on extreme conditions!
In addition to the air temperature/air humidity of the transported medium, the tem-
perature/humidity of the ambient air is also critical. Observe the condensation lim-
its.
