INSTALLATION
EN
1. PRODUCT MOUNTING See "General Warnings" N°.1 to N°.6
For product installation, refer to drawings section 1 page 87 and page 88.
2. HYDRAULIC CONNECTION See "General Warnings" N°.10 to N°.14
For hydraulic connection, refer to drawings section 2 page 91.
- It is necessary to clean the supply piping prior to the hydraulic connection. The
connection to the hot water outlet is to be carried out with a dielectric connector,
to avoid corrosion of the pipe (direct contact iron / copper). The use of brass
fittings is prohibited. The installation must include a pressure reducer, if the
supply pressure is greater than 0.5 MPa (5 bar). The pressure reducer must
be fitted to the outlet of the main distribution supply. A pressure of 0.3 to 0.4
MPa (3 to 4 bar) is recommended.
- Always install a new safety device on the cold water pipe of the water heater, which
comply with the standards (EN 1487 in Europe), with a maximal pressure of 0.7 or 0.8
MPa (7 or 8 bar) according to the nominal pressure, with diameter 1/2".
- CAUTION: Do not use the safety valve included in this packaging in France (home
country and French overseas).

3. ELECTRICAL CONNECTION

For electrical connection, refer to drawings section 3 page 93.
- The water heater can be connected and operated only on AC 230 V. Connect
the heater with a rigid cable with conductors 2,5 mm². Use a standardised
channeling (rigid or flexible conduit) until the calibrated housing cover.
- Directly connect devices with a cable or plug. In France, a product with plug is strictly
prohibited and cannot be installed.
- Always connect the earth conductor of the cable to the earth ground wire or
connect the earth conductor to the appropriate terminal identified by the
symbol . This connection is compulsory for safety reasons. The earth wire
green - yellow must be longer than those of phases. The installation must be
.
