Product description Installation example of a JRG Coral force 6500 in the cold water connection of a multi-residential building downstream of the water meter, filter, and pressure regulator. Any other use of the device or use beyond what is specified is considered to IMPROPER USE.
Product description Description of function The functioning of the JRG Coral force limescale conditioners is based on the patented WATERCRYST catalyst technology. This leaves the valuable minerals in the potable water and does not alter its natural composition. The stainless steel tank contains (1) a loose bed of the active, fine-grained, polymer catalyst granulate (2), above which are found the specific lighter filter granules (3) made of polypropylene, as well as star filters (4.5) in the inlet and outlet made of food-grade and temperature-resistant plastics, which retain the catalyst granulate (2) in the tank (1).
Page 15
Product description A control and monitoring electronics system ensures automatic and correct operation. Microbiological degradation of the equipment is prevented by regular, automatic, thermal disinfection (TDI). During the TDI the catalyst cartridge is disconnected from the water supply line via a valve unit; a bypass in the valve continues to ensure the potable water supply. The water in the cartridge is heated to 80 °C and, after a reaction time of about 90 minutes, flushed out.
Control and monitoring module 3 Control and monitoring module The control and monitoring module provides the following functions: • Self-test and automatic commissioning • Monitoring the functioning of the device components Multi-chamber piston slide valve position control Heating relay and heating current monitoring of the TD module Temperature monitoring WT, TD and BF Motor function for multi-chamber piston slide valve drive Fail-safe (automatic bypass switch during a power failure)
