12.2.12.2 - Installation, operation, adjustments
The instructions given for standard units (BPHE) are also
valid for units with option 280 (STHE), including those relating
to the operating range (Application data section), to frost
protection (Water connection section), and to the installation
settings (Adjusting the nominal flow rate of the installation).
However, it should be noted that the data in the sub-sections
must be replaced by the table and graph below:

12.2.12.3 - Combination with the Brine Option (Options 5B or 6B)
The instructions given for standard units (BPHE) are also
valid for units with option 280 (STHE), with the exception of:
-
the minimum exchanger water outlet temperature which
is limited to -12°C when used with the low-temperature
brine solution (Option 6B). It remains unchanged and
limited to 0°C when using the medium-temperature brine
solution (Option 5B).
-
the refrigerant charge with Option 6B - the adjusted
values are given in the following table:
