GB
Use the electropump for the applications listed on the nameplate.
Do not operate the pump dry, since lack of water could cause it to overheat. In this case, the water inside the system
gets very hot, so there is a risk of scalding. Take off the plug and let the system cool down.
Do not run the electropump with a completely closed delivery.
