7.4.1 Adjusting the cooling water flow regulator
The cooling water flow regulator only needs to be adjusted if the on-site cooling water is significantly warmer or colder
than the set value used during the test run. This set value can be found on the label on the cover of the cooling water flow
regulator. If the temperature deviates by 10 °C or more, we recommend adjusting the cooling water flow in small incre-
ments (approx. 0.1 on the scale). The temperature difference between the cooling water inlet and outlet temperature
should be 15 – 20 K. To adjust the cooling water flow regulator, open the cover of the cooling water flow regulator at the
back of the appliance.
