ZUWA Impeller Pumps Material damage due to overheating of engine > Ensure sufficient space and air supply for the motor. Caution The pump can be fitted vertically or horizontally. In case of vertical fitting, it is advantageous to direct the pump head downwards, so that in case of leaking the motor is protected against escaping liquid. - Page 12 ZUWA Impeller Pumps Motor damage can arise due to unsuitable extension cable > For extension cables of length up to 20 metres: Use cables with at least the same cross section as the pump cable. Caution > For extension cables with a length of more than 20 metres: Use cables with a larger cross section than the pump cable.
