Water connection

CAUTION: Damage to appliance
connections through contact corrosion!
▶ Use galvanic isolators 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.
▶ Install a thermostatic regulator on the
output pipe of the device if PER pipes are
used. It will be set according to the
performance of the material used.
▶ The pipes used must support 10 bars (1
MPa) and 100 °C.
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.
▶ Identify the piping for hot and cold water, in order to avoid
a possible change (Fig. 9).
