8 Malfunctions
It is normal that from time to time a small amount of water escapes
through the mechanical seal. This applies in particular to the running-in
period.
The main factors influencing the efficiency of the mechanical seal and
subsequent leakage is the water quality and the number of operating
hours.
Replace in the event of permanent leakage.
In the event of any irregularities please notify the swimming pool manu-
facturer.
