7. TROUBLESHOOTING
OVERLOAD PROTECTION:
The pump has a thermal overload safety device. In the event of any overhea- ting of the motor, this device automatically
switches off the pump. The cooling time is roughly 15 to 20 minutes, then the pump automatically comes on again.
If the overload cutout is tripped, it is essential to identify and deal with the cause of the overheating.
See Troubleshooting.
