Setting Up
7.
Have the water inlet into the cabinets opened by specialised personnel. If present,
open the shut-off valves upstream of the cabinets in the double bottom.
8.
Insert the venting hose into a vessel with a capacity of 1.5 litres minimum.
9.
Open the vent valve with the supplied square socket key and let the air escape.
Close the vent valve when water starts to flow out.
10.
Repeat these steps (starting with 7) for all of the cabinets.
Test run:
1.
Connect the power supply.
2.
Switch the cooling modules on via the operating unit.
Note
The fans will briefly run with maximum speed. Then, they will be set back to their
nominal speed. Since, at this point of time, there is no heat load in the cabinets, the set
temperature (e.g. 20°C) will be reached rather quickly.
3.
Open the vent valve once again briefly after the test run in order to check whether
any air has collected in the heat exchanger.
The system is now completely filled with water and vented.
