Notes:
- For continuous operation, the maximum temperature delta (REWT-ULWT) should not exceed 10 ° C.
1
For continuous operation, REWT must be within the range of 8.0 ° C to 20.0 ° C.
2
The standard control setpoint is 5 ° to 14 ° C. This value may vary depending on the FLWD of the project and the unit
number confi gured in the control. In continuous operation at full load the maximum ULWT shall not exceed 15.0 ° C. For
more details refer to the Attachment III in this manual.
