Removal from service
If the JUDO UNIDOS digital dosing pump system is to be placed out of service for a long time, the dosing
pump must be thoroughly flushed through with clean water. Then ensure that the dosing pump is
hydraulically depressurised and voltage-free. Remaining dosing medium must be properly disposed of. The
