Water quality requirements on the circuit
Water quality must meet the standards of European Directive 98/83 EC and the criteria
set out in UNE 112.076. Water quality should be analysed before use; to evaluate criteria
such as concentration, pH value, conductivity, chloride ion concentration (Cl-), sulfide ion
concentration (S2-), etc. Some of the parameters on the chemical ingredients are indicated
in the following table:
Parameter
Acrylamide
Antimony
Arsenic
Benzene
Benzopirene
Boron
Bromate
Cadmium
Chrome
Copper
Cyanide
1.2-dichloroethane
Epiclorohydrin
• PH value: between 6.5 and 8.5
• Water hardness: <50ppm.
Before connecting the outdoor unit:
In any installation, both new and existing, a thorough cleaning of the pipes should be
carried out using a suitable chemical cleaning product,and then wash the pipes to clean
said chemical agent. To avoid damage to the pipes, you should add anionic, cationic
corrosion inhibitors, a mixture of both or film products that block the existing microlays,
avoiding corrosion reactions and oxygen detachment. When using inhibitors or other
cleaning chemicals, always read the manufacturer's instructions and their compatibility
with the materials that make up the installation.
Antifreeze
In case the installation is to operate in refrigeration mode, it is mandatory to use anti-
freezing. In installations that do not operate in refrigeration mode, it should be used when
there is a risk of freezing during a period of non-operation or due to environmental
conditions. Antifreeze solutions should use propylene glycol with a Class 1 toxicity index.
Ethylene glycol should never be used in the primary circuit.
Problems arising from poor water quality or not having treated water as described herein
are not covered by the product warranty.
