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
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.
