We recommend installing the appliance ( A Fig. 1) as close as possible to the delivery points to minimise heat loss
along the pipes. Local regulations may provide for restrictions on installation in bathrooms; observe any regula-
tory minimum distances. To facilitate maintenance, make sure there is a clearance of at least 50 cm inside the
enclosure for access to the electrical equipment.
Hydraulic connection
Connect the water heater’s inlet and outlet with pipes or fittings that are able to withstand temperature in excees
of 90°C at a pressure exceeding that of the working pressure. Therefore, we advise against the use of any materi-
als which cannot resist such high temperatures.
The appliance must not be supplied with water of hardness less than 12°F, nor with especially hard water (greater
than 25°F); we recommend installing a water softener, properly calibrated and controlled - do not allow the re-
sidual hardness to fall below 15°F.
Screw a “T” piece union to the water inlet pipe with the blue collar. On one side of the “T” piece union, screw a
tap for draining the appliance that can only be opened with the use of a tool ( B Fig. 2). On the other side of the
“T” piece union screw the safety valve supplied ( A Fig. 2).
Safety group complies with the European standard EN 1487
Some countries may require the use of hydraulic special safety devices; the installer must check the suitability of
the safety device he tends to use.
Do not install any shut-off device (valve, cock, etc.) between the safety unit and the heater itself.
The appliance's drain outlet must be connected to a drain pipe of diameter at least equal to the of the outlet itself,
with a funnel to permit an air gap of at least 20 mm for visual inspection. Use a hose to connect the safety group
to the mains cold water supply; fit a cock if necessary ( D fig. 2). In addition, a water discharge tube on the outlet
C Fig. 2 is necessary if the emptying tap is opened.
When installing the safety device, do not tighten it fully down, and do not tamper with its settings.
It is necessary to connect the drain, which must always be left exposed to the atmosphere, with a drainage pipe
that is installed sloping downwards in a place with no ice. If the network pressure is closed to the calibrated valve
pressure, it will be necessary to apply a pressure reducer far away from the appliance. To avoid any possible
damage to the mixer units (taps or shower) it is necessary to drain any impurities from the pipes.
Electrical connection
It is mandatory, before installing the appliance, to perform an accurate control of the electrical system by verifying
compliance with current safety standards, which is adequate for the maximum power absorbed by the water heater
(refer to the data plate) and that the section of the cables for the electrical connection is suitable and complies with
local regulations. The manufacturer is not liable for damage caused by lack of grounding or anomalous power
supply. Before starting up the appliance, check that the power rating matches that given on the nameplate.
The use of multiplugs, extensions or adaptors is strictly prohibited.
It is strictly forbidden to use the piping from the plumbing, heating and gas systems for the appliance earthing
connection. If the appliance is supplied with a power supply cable, should the latter need replacing, use a cable
featuring the same characteristics (type H05VV-F 3x1.5 mm 2 , 8.5 mm in diameter. The power cord (type H05VV-F
3x1,5 mm
2
dim. 8.5 mm) must be routed into the hole in the back of the appliance and connected to the thermo-
stat terminals or terminal block clamps.
Use a two-pole switch conforming with national laws in force (contact gap of at least 3 mm, preferably equipped with
fuses) to disconnect the appliance's power supply.
The appliance must be grounded with a cable (yellow/green and longer than the phase cable) connected to the
terminals marked .
Before starting up the appliance, check that the power rating matches that given on the nameplate. If the appli-
ance is not supplied with a power supply cable, choose one of the following installation modes:
- connection to mains with a rigid pipe (if the appliance has no cable clamp); use a cable with a minimum 3x1.5
mm
2
section;
- with a flexible cable (type H05VV-F 3x1.5mm 2 , 8.5 mm in diameter) if the appliance is supplied with a cable
clamp.
Testing and ignition of the device
Before powering up the appliance, fill the heater with mains water.
To do so, open the mains cock and the hot water tap until all the air has been vented from the boiler. Check for
leaks from the flanges, tighten down the fittings (not too much!) if necessary.
Turn on the appliance with the switch.
