3.1.2 Filling
Close the ball valves and remove the filter cartridge.
Figure 8: ball valves
Figure 9: flow guide and venting valve
Set the flow guide into the inlet hole to fill water from one side only. Open the venting valve and fill the ap-
paratus with water (approx. 10 l at 6 stations). Switch ON the temperature controller to activate the water
circulation. As soon as water flows out of the venting valve, the system is vented and the venting valve has
to be closed. Install the filter cartridge as described in section
. The filling height in the basin should be
approx. 55 mm after venting without samples (upper edge of the flow guide). For each sample, the water
level rises by approx. 2.5 mm.
Caution!
To prevent damage of the heat exchanger, close the middle valve before switching
on the temperature controller.
Note!
If there is no water flow into the filter or the pump does not promote water, please
turn off temperature controller switch, remove filter cartridge, open both ball valves
and drain some water to carry out any air bubbles from the system. Then close the
ball valves and turn on temperature controller switch. Mount filter cartridge (section
). Repeat this procedure if necessary.
Keep ball valves closed
