Water connection

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.
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.
The water heater connections for the inlet and outlet of water
are colour-coded. The inlet of cold water is marked with blue
colour, while the hot water outlet is marked with red colour.
The water heater can be connected to the water supply in two
ways. The closed-circuit pressure system enables several
points of use, while the open-circuit gravity system enables a
single point of use only. The mixer taps must also be installed in
accordance with the selected installation mode.
▶ Identify the piping for hot and cold water, in order to avoid
a possible swop (Fig. 7).

In a closed, pressurized system ( Fig. 8) pressurised mix
taps should be used at the outlet points. To ensure safe
operation of the heater a safety valve should be installed on the
inlet pipe to prevent elevation of pressure for more than 0.1
MPa (1 bar) above the nominal pressure. The outlet opening on
the safety valve must be equipped with an outlet for
atmospheric pressure. The heating of water in the heater
causes the pressure in the tank to increase to the level set by
the safety valve. As the water cannot return to the water supply
system, this can result in dripping from the outlet of the safety
valve. The drip can be piped to the drain by installing a catching
unit just below the safety valve. The drain installed below the
