If power consumption increases forwhatever reasons, e.g. in case of calcification resultingin sluggish bearings – the electronic system of the pumprecognizes this as a failure and the pump is switched offautomatically. By plugging/unplugging the power plug the pump can bemade ready for operation again. Please note that it is pro-hibited to circumvent the electronics to make the pump runagain by constantly plugging/unplugging the power. If theRed Dragon® pump switches off, there is always a problemwhich must be remedied. This is usually a cleaning intervalthat is to be implemented. Continuous circumventing of thepump electronics may result in motor damage which is notcovered by guarantee or goodwill. Furthermore, major im-purities may generate vibrations. We recommend to check the Red Dragon® pump already afterthree months, to determine the possible maintenance intervalsthat, can be depending on precipitation between 2-12 months.
