10 Maintenance and Service
In addition to the usual periodic inspections of the technical systems in accordance with the
regulations and standards valid in this field of application, the catalyst granulate in JRG Coral
force limescale conditioners must be replaced every five years. Georg Fischer JRG offers a
service kit for this purpose. (For the part number, see 'Spare Parts and Service Kit')
The service intervals for granulate change are monitored by an operating hours counter and are
displayed as follows:
