Water Condittions: VJater mnditions and minerel content vary in difterent regions. If excessive mineral buildup is found in the pump it may be necessary to use a water condi- Goner or water softener. Hard water may cause calcium build-up and evenNally reduce 7ie I"rfe of the pump and other systam components. � Note: The laing Autocirc pump is salf-lubricated and never �equires lubrication of any kind. It should provide years of trouble free service when properly installad. �� Where hard water conditions exist, we reeommcnd that the Autoeirc pump head bo � takan off pariodieally and checked for caicium or othar minerel build-up.
