5.2. Circulating pump U 4854 (Aquavent 5000S)
NOTE:
When connecting the circulating pump it must be ensured that the
volume flow does not drop below 2500 l/h for longer than a brief period
only! Continuous operation at less than 2500 l/h will result in undue wear
of the wearing disc of the impeller!
