* When the flow rate falls below the limit indicated (flow rate controller activation threshold), the flow rate controller
indicates alarm 06 which may only be reset when the flow rate controller deactivation threshold is exceeded.
For more detailed information, we provide a table below which indicates the minimum flow rates
to be guaranteed on the condenser to ensure that it operates correctly according to the model, as
well as the disconnection and re-engagement flow rates for the flow rate controller.
Water flow rate on the condenser
The nominal water flow rate is determined for a temperature difference of 5°C between the inlet
and the outlet of the condenser. The maximum authorised flow rate is that with a temperature
difference of 3°C whereas the minimum is that with a temperature difference of 8°C in nominal
conditions, as shown on the data sheet.
Note: the water flow rate controller is used to avoid the failure of the anti-freeze sensor
due to insufficient flow rate but does not guarantee the minimum flow rate required for
correct operation of the unit.
INFORMATION:
Insufficient water flows can cause too low evaporation temperatures with
the intervention of safety devices and unit shutdown and, in some extreme
cases, ice formation in the evaporator and serious failures of the refrigeration
circuit.
