4.2.1.8.3 - Purging the installation
The oxygen present in the air is extremely corrosive.
All necessary
measures must be taken to ensure that the installation can be
continuously purged. Automatic air purging valves should be placed
at each high point of the installation, and manual air purging valves
should be installed on each radiator.
Any deterioration of the appliance due
to inappropriate fi
lling water, and/or
corrosion in the absence of the use of treatment
products, and/or improper purging of the
installation, will render the warranty null and
void.
RENDERING THE WARRANTY NULL AND VOID
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, fi bres, soldering
fl 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 .
4.2.1.8.2 - 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 off ers effi
cient resistance to corrosion. To fi nd
this information refer to their user manual.
• 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.
Central heating installations must be
cleaned in order to eliminate debris
(copper, fi 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 underfl oor heating).
PRODUCTS USED FOR HEATING WATER
TREATMENT MUST BE APPROVED BY THE
LOCAL OR NATIONAL PUBLIC HYGIENE AND
HEALTH AUTHORITY.
4.2.1.8.1 - Filling water
The materials used for producing a heating circuit are of diff erent
natures. Instances of corrosion may occur through galvanic coupling
in both new and existing installations.
The fi 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:
