CAUTION: Damage to appliance
connections through contact corrosion!
▶ Use galvanized insulators in your water
connections. These will avoid galvanic
electric currents between the hydraulic
link metals and, consequently corrosion
of these.
NOTICE: Material damage!
▶ Install a filter at the water inlet in areas
where the water contains particles or
sediments.
NOTICE: Material damage!
▶ So as to avoid corrosion, colour and
odour in the water, take into account the
information in table 2 with the drinking
water requirements in addition to the
possible need to adjust the installation
to the type of water (for example, adding
filtering systems or changing the supply
source).
It is recommended:
▶ to purge the system before appliance
installation, the existence of sand can
cause a reduction in flow or even cause a
total obstruction.
