1 Safety

1.1 General safety instructions

Danger This appliance is not intended for use by persons (in cluding children) with reduced physical, sensory or mental capabilities, or lack of experience and knowl edge, unless they have been given supervision or in struction concerning use of the appliance by a person responsible for their safety. Children should be super vised to ensure that they do not play with the appli ance.

Warning Only qualified professionals are authorised to work on the boiler and the heating installation.

Caution A disconnection method must be allowed in the fixed pipes in accordance with the rules on installation in force in the country.

Danger of electric shock

Danger If you smell flue gases:

1. Switch off the appliance.

2. Open the windows.

3. Evacuate the premises.

4. Contact a qualified professional.

Warning Do not touch the flue gas pipes. Depending on the boiler settings, the temperature of the flue gas pipes may exceed 60°C.

Warning Do not touch the radiators for long periods. Depending on the boiler settings, the temperature of the radiators may exceed 60°C.

Warning Take precautions with the domestic hot water. De pending on the boiler settings, the domestic hot water temperature may exceed 65°C.

Caution If a power cord comes with the appliance and it turns out to be damaged, it must be replaced by the manu facturer, its after sales service or persons with similar qualifications in order to obviate any danger.

1 Safety

7642066 - v01 - 29092015 EFU 5

Note Respect the minimum and maximum water inlet pres sure to ensure correct operation of the boiler: refer to the chapter Technical Specifications.

Caution Do not neglect to service the boiler. Contact a quali fied professional or subscribe to a maintenance con tract for the annual servicing of the boiler.

Caution Only genuine spare parts may be used.

1.2

Recommendations

Caution The installation must satisfy each point in the rules (DTU, EN and others, etc.) that govern works and in terventions in individual homes, blocks of flats or other buildings.

Note Keep the boiler accessible at all times.

Caution Install the boiler in a frost-free location.

Caution The appliance should be on Summer or Antifreeze mode rather than switched off to guarantee the follow ing functions:

Anti-blocking of pumps Frost Protection

Note Regularly check the presence of water and pressure in the heating installation.

Note Never remove or cover labels and data plates affixed to the appliances. Labels and data plates must be legible throughout the entire lifetime of the appliance. Immediately replace damaged or illegible instructions and warning stickers.

Note Remove the casing only to perform maintenance and repair work. Put the casing back in place after mainte nance and repair work.

Note Insulate the pipes to reduce heat losses to the mini mum.
