As other hydronic appliances, Robur heating and cooling systems operate with grid-water
of good quality. In order to prevent any possible problem of operation or reliability caused
by filling or top-up water, please refer to codes and norms about water treatment for
thermo-hydraulic installations in civil or industrial applications. Parameters indicated in
Table 20 must be complied with.
Table 20
-
Chemical and physical parameters of water.
Water quality can be measured through parameters like acidity, hardness, conductivity,
chlorides content, chlorine content, iron content and the like.
The presence of free chlorine in the water, in particular, can jeopardize parts of the
installation and Robur units. Therefore, please make sure that free chlorine content
and total hardness are compliant with the allowable ranges reported in Table 20.
The way the installation is operated can be the cause of possible degradation of water
quality.
Moreover, abnormally massive water top-up or reintegration can cause a drift of chemical
or physical above-mentioned parameters. Reintegration should not exceed 5% per year of
the total amount of water. It is advised to check regularly the water quality, especially in
case of automatic or periodic top-up.
In case water treatment is needed, this operation should be carried out by a professional
or competent person, following strictly the instructions by the manufacturer or supplier of
the chemical substances for the treatment, since dangers could arise for health, for the
environment and for Robur appliances.
Several products for water treatment are available on the market.
Robur does not perform detailed market surveys. Therefore Robur suggests to contact
Companies which are specialized in water treatments. They will be able to suggest the
best way how to proceed according to the type of installation
In case washing of the pipes is needed, this operation should be carried out by a
professional or competent person, following strictly the instructions by the manufacturer or
supplier of the chemical substances for the washing, avoiding the use of substances
aggressive for stainless steel or containing/releasing free chlorine.
Please make sure the pipes are properly rinsed in order to remove any residue of
chemical substances from the pipes.
