Specifications on water quality
The supply water of the
EGO
solar collector with incorporated accumulator tank must perma-
nently comply with the limits indicated in the following table:
PARAMETER
MEASURING UNIT
REFERENCE VALUE
pH
-
6,0 - 9,5
chloride
mg/l
2500
Residual disinfectant
mg/l
< 0,2
iron
μg/l
< 400
sulphate
mg/l
< 500
conductibility
μS/cm a 20°C
< 2500
For any parameters not listed in the table, the limits imposed for water
intended for human
consumption
are applicable, as laid down by Directive 98/83/EC and subsequent amend-
ments, and as transposed by the respective decrees of each EU Member State, including the
outermost regions (ORs) and overseas countries and territories (OCTs). For non-EU countries,
the limits set by the local regulations shall be applicable.
The collector cannot be used with sea water, swimming-pool water, or any other fluids diffe-
ring from water. The use of water that fails to comply with the provisions in this paragraph
will invalidate the product warranty. The electrical resistors (antifreeze and integration) can
be used with chlorine levels up to twice the limit imposed by Directive 98/38/EC and subse-
quent amendments.
Hardness
It is recommended to use water with a hardness of between 10° F and 30° F. In the case of wa-
ter with a greater hardness than 30° F it is recommended to carry out a softening treatment,
otherwise the EGO solar collector and its components, such as the by-pass valve, safety and
non-return valve, electric resistors, etc., may be subject to limestone deposits and as a result,
any damage to the collector caused by the malfunctioning of the aforementioned components
(valves and resistors) will not be covered by the warranty.
Damage to the valves and resistors as a result of the hardness of the water, should this exceed
the recommended limits, will not be covered by the warranty.
If the water has a hardness of over 30°F and is not softened, there could be a drop in the final
yield and it will be necessary to carry out periodic maintenance operations on the valves and
resistors, with an appropriate frequency depending on the hardness level in order to guaran-
tee correct operation over time.
