Legend:
Operating range, unit equipped with option 28 (winter operation).
Below 0 °C air temperature the unit must either be equipped with the
evaporator frost protection option (41A or 41B), or the water loop must
be protected against frost by using a frost protection solution (by the
installer).
Part load average
ATTENTION: Option 28 (Winter operation)
If the outside temperature is below -10 °C and the unit has
been switched off for more than 4 hours, it is necessary to
wait 2 hours after the unit has been switched on again to allow
the frequency converter to warm up.

6.2 - Minimum chilled water flow (units without
hydraulic module)
The minimum chilled water flow is shown in the table on the next
page. If the system flow is less than this, the evaporator flow can
be recirculated, as shown in the diagram.
