•The unit must be connected to a correctly installed, earthed and fused three-phase
power socket (400 V/50 Hz).
•Insert the power plug only after assembly is complete.
•Do not expose the system to direct moisture. In particular, ensure that no water
drips onto it from above.
•Check regularly that the system is watertight and correctly functioning and observe
the prescribed inspection and maintenance intervals and the measures provided
for this purpose accurately.
•Before performing maintenance or repair work, ensure that access to the working
area of the limescale conditioner for unauthorised persons is blocked.

Seite 8 von 68 Rev.: 1113803-1

2Product description
2.1 Intended Use
The JRG Coral force 8000,
11000, 14000, 3.5D, 5D limescale conditioning
units are designed to provide long-term
reductions in limescale formation in potable
water installations and sanitary systems. The
biomineralisation process is based on a
principle that protects against limescale build-
up without the use of chemical additives or
electrolytic decomposition of water.
The units are designed solely to be installed in
the main potable water system inlet of
apartment buildings, hospitals, hotels, schools,
and other public buildings and of commercial
and industrial premises.
Unit selection and sizing should be carried out
according to Georg Fischer JRG’s planning
documents and design specifications.
JRG Coral force 14000
This unit is not suitable for:
•Technical systems for which full or partial desalination is required or
prescribed by the manufacturer.

Seite 11 von 68 Rev.: 1113803-1
Installation example with JRG Coral force 14000 in the main potable water system inlet, fitted
after the water meter and a domestic water station with filter, RV and pressure control valve.
Any other or additional use of this equipment is deemed to be NOT FOR
INTENDED PURPOSE.
The manufacturer/supplier assumes no liability for damage caused by non-
observance of these operating instructions or applicable regulations or for
damage caused by improper use. In such cases all risk is borne by the
user/operator.

Seite 12 von 68 Rev.: 1113803-1
2.2 Principle of Operation
JRG Coral force limescale conditioners function on the basis of patented WATERCRYST catalyser
technology. This leaves the valuable minerals in the potable water and does not alter its natural
composition.
The stainless steel tank (1) contains a loose bed of active, fine-grained polymer catalyst
granulate (2), above which are filter granules of lower specific weight (3) in polypropylene and
filter stars (4, 5) in the water inlet and outlet. These are made of food-safe, temperature-
resistant plastics and serve to keep the catalyst granulate (2) in the tank (1).
The water to be treated flows and swirls (A) through the catalyst granulate (2). Imitating natural
bio-mineralisation processes, tiny crystals of lime from the hardeners dissolved in the water are
deposited on the surface of the catalyst (B). These tiny lime crystals are then stripped from the
catalyst surface by the water being treated (C) and spread throughout the entire installation
system by water removal (D). The result is a protective deposit of tiny lime crystals that act
throughout the entire hot water system (the Udeposit effectU).
A
B und C
D
E
If lime is now precipitated within the system, it is separated out onto the lime crystals present in
the water (D). As the crystals grow, they do not attach themselves to any surface and are flushed
out of the installation as water is extracted.
There is consequently a significant reduction in limescale deposits on pipes and boiler walls,
heating registers and valves.
An electronic control and monitoring system ensures that the unit functions automatically and
correctly.

Seite 13 von 68 Rev.: 1113803-1
Regular thermal disinfection (TDI) is performed automatically to prevent harm to the unit being
caused by microbiological action. During this process the catalyst cartridge is isolated from the
drinking water supply by means of a valve, while a bypass in the valve ensures that the supply of
drinking water continues unaffected. The water in the stainless steel vessel is heated to 75°C
and left to act for 90 minutes before being flushed out.
JRG Coral force limescale conditioners leave the valuable minerals in the water
and do not cause softening. When water evaporates from tiles, fittings or
shower walls, the minerals are left on the surfaces; over time, residues build up.
You should therefore maintain and clean your bathroom and sanitary facilities
regularly. You can find important advice on the Georg fischer JRG homepage

*) The maximum number of residential units (RU) specified in the table refers, under VDI 3807-T3, to an
average occupancy of 2.2 persons per RU and an average water consumption of 100 litres/person/day. While
these statistical average values must be considered during planning and design of limescale protection
systems, in practice significant variations may occur depending on the occupants' usage behaviour and actual
occupancy rates.
In principle the layout of JRG Coral force limescale conditioner systems should
comply with Georg Fischer JRG’s planning recommendations.
The relevant documents and planning information can be found in our planner
documentation.
