The pump is supplied by a universal power supply with inte-
grated overload protection. It is protected against overheating
by a temperature sensor on the motor board and equipped with
overcurrent protection.
If one of these safety functions is triggered, the pump will be
shut down and must be manually reset, as follows:
➔
Separate pump from electrical power supply
➔
Remove the cause(s) of the fault before restarting.
