ATTENTION
►
Liquid cooling systems and other components in the cooling circuit
must be operated parallelly.
► Pay attention to flux direction and check tightness !
•
The min. volume flow depends on the total power loss.
•
Max. temperature difference (ΔT) between inlet and return flow 7 K.
•
A volume flow over 40 l/min increases the risk of erosion in the
liquid cooler.
• A discontinuous operation is not permitted, this leads to immediate
destruction of the dunit.
•
For further details on the AFE filter, please refer to the technical
data sheet of the filter.
