INSTALLATION
5.2.2 Connection of the domestic hot water
cylinder (option)
• Refer to the instructions supplied with the 2-way valve
and the domestic hot water cylinder for their hydraulic
connections to the boiler circuit.
5.3 Heating circuit
5.3.1 Connection from the hydraulic module to
the heating circuit
i Make the connection limiting the load losses to a
minimum (the circuit should be as short as possible,
avoid bends and narrow sections...).

6 Electrical connections
e
Incorrect installation can cause electric shock or
appliance damage. The electrical connection of
the appliance must be made only by a qualifi ed
engineer.
The appliance must be connected directly to an accessible,
fi xed, switched, electrical outlet.
The manufacturer declines any responsibility for damages to
persons or others caused by the incorrect installation of the
appliance earthing. This includes failure to comply with current
standards.
Electrical components have been tested to meet the equivalent
requirements of BSEN 7671 and the BEAB regulations.

2 Insulation
When you connect the electrical wires to a connector on the
electronic board:
• Maintain a maximum distance of 20 mm between the
connector and the outer insulation.
• If using single core wires are used ensure that they are
wrapped together in an insulating sheath.
6.1 Heat pump
The cables connecting the isolator and the heat pump must be:
- suitable for a fi xed installation.
- weather resistant.
- equipped with wires adapted to appliance’s power rating.
• Connect the heat pump to an electrical panel via an
independent protection system (20A differential breaker with
at least 3 mm between each contact).
Additional protection may be required during installation to
ensure overvoltage category II.
