5.4 Water connection
▶ Identify the piping for hot and cold water, in order to avoid
a possible swap (Fig. 9).
Fig. 9
[1] Cold water inlet (right hand side)
[2] Hot water outlet (left hand side)
In case of vertical installation, ensure that the
water connections are positioned on the
bottom part of the appliance and in vertical
position.
NOTICE: 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.
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.
