We recommend the use of products in the SENTINEL range 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, fibres, soldering
fluxes) Example : SENTINEL X300 or SENTINEL X800.
- 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 or SENTINEL R600.
• For existing installations:
- Desludge the installation with a desludging product to
eliminate any sludge from the installation. Example :
SENTINEL X400 ou SENTINEL X800.
- 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 or SENTINEL R600.
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 offers efficient resistance to corrosion.
To find this information refer to their user manual.
In cases where the HRC
70
Heat Pump cannot operate (exterior
temperature is outside of the operating range), and a back-
up is authorised (boiler or electrical), it will automatically be
protected from frost or ice as the circulator pump will operate
and draw heat from the heating circuit which has its temperature
maintained by the HRC
70
Pilot’s electrical back-up or back-up
boiler.
However, in the case of installation without a back-up, or if the
HRC
70
Pilot or HRC
70
Heat Pump is being switched off during the
winter months (ex. accidental stop, secondary residence, etc...), an
additional anti-freeze protection is necessary to prevent having
to drain the hydraulic circuit of the Heat Pump located outside of
the building.
For anti-freeze product, use «monopropylene glycol» with an
added corrosion inhibitor.
A6.4 - Protection from freezing
Choose the % of glycol based on the minimum exterior
temperature to protect the water circuit from freezing (the
concentration should not be under 25%) :
Exterior temperature (°C)

Do not use mono-ethylene glycol
(toxic product)
When using a concentrated product which
needs to be diluted with water, mix the
water+anti-inhibitor mixture together
prior to inserting it into the installation.
• Regularly check the pH level and % of
glycol in the installation.
•Never top-up the glycol in your installation
without measuring the pH to check that
the drop in the % of glycol is not due to a
deterioration of the glycol in the installation.
•When the pH is acidic (<7) replace all of the
glycol after having already drained and rinsed
the installation.
RENDERING THE WARRANTY NULL AND VOID
All deterioration of the appliance due to
an inappropriate quality of water and/
or the presence of corrosion in the absence of
treatment products as described above, and/
or an improper purging of air in the installation
will render the warranty to be null and void.
