RECOMMENDATIONS
Dispense just soluble products and take care that they do not crystallize.
Do not use very dense or thick products.
Consult before using acid products (chloride, acetic acid…), alkaline (detergents, chlorine...)
or solvents.
In case you use some tools to manipulate the equipment, it is recommended not to force on
the pieces because most of them are closed by means of O-ring gaskets.
4. DESCALING PRODUCT
It is a liquid descaling product against corrosion and incrustation for closed circuits.
It is principally made of: molybdates, polyacrylates, organic polymers and corrosion inhibitors.

CHEMICAL PROPERTIES
This product should be employed in closed circuits, cold or hot water, or in those cases requiring
the maximum effectiveness that no other products can achieve.
Thanks to its chemical stability and its dispersing action, it has an excellent inhibiting effect of
large duration in all metals (steel, copper, aluminium, brass, zinc, etc…).
4.3.
TREATMENT DOSES
They will depend on the water quality and on the system work conditions.
The recommended doses are:
- 2-3 gr/litre in water of very low hardness or in circuits where the treatment is applied for the first
time.
- 1 gr/litre in hard waters or in doses for maintenance.
No more quantity of product should be added if there is no water refilling in the circuit.
