This product is a device that must be installed vertically in order to operate correctly. Once installa-

tion is complete, and before any water is added or the power supply is connected, use a measuring

instrument (i.e. a spirit level) to check that the device has been installed perfectly vertical.

The appliance heats water to a temperature below boiling point. It must be linked up to a mains water

supply according to the appliance performance levels and capacity.

Before connecting the appliance, it is ﬁ rst necessary to:

- Check whether the characteristics (please refer to the data plate) meet the customer's requirements.

- Make sure the installation conforms to the IP degree (of protection against the penetration of liquids)

of the appliance according to the applicable norms in force.

- Read the instructions provided on the packaging label and on the appliance data plate.

This appliance was designed to be installed only inside buildings in compliance with the applicable

norms in force. Furthermore, installers are requested to keep to the following advice in the presence of:

- Damp: do not install the appliance in closed (unventilated) and damp rooms.

- Frost: do not install the appliance in areas where the temperature may drop critically and there may

be a risk that ice may form.

- Sunlight: do not expose the appliance to direct sun rays, even in the presence of windows.

- Dust/vapours/gas: do not install the appliance in the presence of particularly dangerous substances

such as acidic vapours, dust or those saturated with gas.

- Electrical discharges: do not install the appliance directly on electrical supplies that aren't protected

against sudden voltage jumps.

In the case of walls made of bricks or perforated blocks, partition walls featuring limited static, or mason-

ry diff erent in some way from those stated, you ﬁ rst need to carry out a preliminary static check of the

supporting system.

The wall-mounting fastening hooks must be designed to support a weight that is three times higher than

the weight of the water heater ﬁ lled with water.

Fastening hooks with a diameter of at least 12 mm are recommended.

To facilitate maintenance, make sure there is a clearance of at least 50 cm inside the enclosure for ac-

cess to the electrical equipment.

PLUMBING WARNING:

Note: If a valve i.e. a non return valve, water meter, pressure reducing valve or any type of valve or

ﬁ tting that acts as a non return valve is installed on the cold water mains, this will prevent expansion.

Therefore it will be necessary to install an expansion vessel (see ﬁ gure below).

Note: If in doubt always install a pressure reducing valve (limited to 3.5bar) and expansion vessel.

The outlet from temperature and pressure relief valve/pressure relief valve must not be for any other

purpose.

Take great care not to allow any swarf into the pipe work or ﬁ ttings, as this might impair the operation of

the safety valve(s). The water connection may be carried out as per the following:
