of ice inside.
" Do not use electrical extensions or reduction gears.
" Do not plug in or unplug the electricity supply cable with wet hands.
" It is strictly forbidden for children to use the appliance without suitable supervision.
" The outlet water, if not mixed, can reach temperatures which could cause scalding.
Take care before using the water

Installation instructions

The appliance (A fig. 2) should be installed as close as possible to the points of use
so as to limit the loss of heat along the piping.
To make maintenance operations easier, allow for 50 cm of free space to access the
electrical parts.
Wall assembly
The hooks for fastening the appliance to the wall must be capable of bearing three times
the load of the water heater filled with water. We recommend you use 10 mm diameter
hooks that are suitable for the type of wall onto which they are fixed.
Vertical installation:
Hang the appliance up onto the hooks (fig. 3-4); for models that go up to 100 litres
(equipped with just one bracket) vertical alignment is possible by acting on the adjustable
device "X" (fig.3), whereas 120 and 150 litre models come with two brackets (fig.4).
Horizontal installation:
Hang the appliance up by inserting the hooks into the special slot of the bracket (fig.5).
N.B. once the appliance has been installed, check the stability of the appliance
by pulling it downwards.
Plumbing connection
Connect the water heater's inlet and outlet with pipes or fittings that are resistant to the
working pressure as well as to the temperature of the hot water that can usually reach
and exceed 80°C. We therefore advise against the use of materials that do not resist
such high temperatures.
Screw a tee union (H fig.6) to the water inlet pipe of the appliance, marked by a small
blue collar. On the one side of this fitting (tee union), screw a valve for draining the water
heater (B fig.6) that can only be operated with the use of a tool, and on the other the
safety valve (D fig.6). Connect the latter to the cold water mains supply pipe.
Also, should the drain tap be opened, allow for a water drain pipe to be attached to the
outlet C fig. 6.
When screwing the safety valve tight, do not force it too much and do not tamper with
it.
Some dripping from the safety valve drain aperture is completely normal during heating.
