For cables with outer diameter of the sheath between 7 mm and 8.5 mm: remove the rubber retainer from the cable
gland. In this case, the circulator can only be installed with the cable gland down.
Activation frequency: activations/deactivations through the mains voltage ≤ 20/24 h.

6. COMMISSIONING
6.1 Start-up of the circulator
Absolutely avoid dry operation. Start the circulator only after having
completely filled the plant.
Circulators with permanent magnets can not be driven in speed by means
of phase control of the supply voltage.
Circulators driven by an electronic frequency converter have a current
peak at each activation (inrush current) greater than traditional
circulators (asynchronous).
The activation stage of the circulator has to be size taking into account
this current peak. For further details contact the manufacturer.
