6 - APPLICATION DATA

6.1 - Operating range

30XAS standard unit
Evaporator leaving water temperature, °C
30XAS unit with option 119
Evaporator leaving water temperature, °C
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).

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 evapo-rator flow can
be recirculated, as shown in the diagram.

6.3 - Maximum chilled water flow (units without
hydraulic module)
The maximum chilled water flow is shown in the table on the next
page. If the system flow exceeds the maximum value, it can be
bypassed as shown in the diagram.
