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 must 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 must 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, antifreeze must be used when there is a risk of freezing during a
period of non-operation or due to environmental conditions. Antifreeze
solutions must use propylene glycol with a Class 1 toxicity index. Ethylene
glycol must 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.
