It is IMPERATIVE to refer to the
installation instructions for the initial
installation of the ambient temperature
thermostat to ensure satisfactory operation.
In an installation with both
thermostatic valves and a room
temperature thermostat, the radiator(s) in
the room in which the thermostat is located
MUST be equipped with a manual valve(s).
Thermostatic valves: these valves should prioritise rooms with
higher levels of heat gain.
4.2.1.8 - Thermostatic valves
4.2.1.9 - Treatment of the water in the
heating circuit
It is MANDATORY to read the additional
document concerning the quality of
water used for lling the installation.This
document is included with this manual as well as
in the packet with the warranty information.
This document also contains information which is
PERTINENT to the WARRANTY of the material.
Central heating installations must be cleaned
in order to eliminate debris (copper, lings,
soldering waste) related to the set-up of the
installation or from chemical reactions between the
metals.
Futhermore, it is important to protect the
central heating installations from risks of
corrosion, limescale, and microbiological
development through use of a corrosion inhibitor
which is suitable for all kinds of installations (steel or
cast-iron radiators, PEX under oor heating).
PRODUCTS USED FOR HEATING WATER
TREATMENT MUST BE APPROVED BY THE
LOCAL OR NATIONAL PUBLIC HYGIENE
AND HEALTH AUTHORITY.
4.2.1.9.1 - Filling water
The materials used for producing a heating circuit are of di erent
natures. Instances of corrosion may occur through galvanic coupling
in both new and existing installations.
The lling of the heating circuit must only be done with untreated water
(no water softener) from the drinking water network. Water from any other
source )rain-water, well-water, etc...), must be analysed and MUST have
the following properties:
8,5 U PH (acidity) U 9,5
Chlorides U 60 mg / litre
Conductivity < 1000 μS / cm
5 U TH (hardness in French °) U 15
We recommend the use of products in the SENTINEL range by GE
BETZ
for preventative and curative treatment of the heating circuit.
• For new installations : (less than 6 months old):
- Clean the installation with a universal cleaner to eliminate
the debris from the installation (copper, bres, soldering
uxes) Example :
SENTINEL X300
- Throughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example:
SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example :
SENTINEL X500.
• For existing installations:
- Desludge the installation with a desludging product
to eliminate any sludge from the installation. Example:
SENTINEL X400.
- Throughly rinse the installation until the water runs clear,
with no traces of impurities left.
- Protect the installation against corrosion with a corrosion
inhibitor, example:
SENTINEL X100. Or against corrosion
and freezing with an inhibitor with an anti-freeze additive.
Example :
SENTINEL X500.
4.2.1.9.2 - Treatment of the heating circuit
Corrosion inhibitor :
- protects against the formation of limescale
- prevents «pinhole» type corrosion
- prevents, in new installations, the formation of sludge
and the proliferation of bacteria
(in low temperature networks: algae)
- prevents the formation of hydrogen
- eliminates the sound of the generators
Treatment products from other manufacturers can be used if they
guarantee that the product is appropriate for all the materials used
in the appliance and o ers e cient resistance to corrosion. To nd
this information refer to their user manual.
Frost protection is necessary if the pilot is switched o during the
winter months (ex: secondary residence, etc...).
4.2.1.7 - Frost protection
If the appliance is connected to an
electricity supply, the heating circuit is
protected from freezing. It is IMPERATIVE
to drain the domestic hot water circuit however.
If the pilot is not being supplied with electricity
(electrical cut-o for example), or it is defective
and there is a risk of freezing, it is IMPERATIVE to
completely drain the appliance (heating and hot
water).
