■ Wiring must be carried out in accordance with the wiring diagram supplied with the unit and the instructions given in this paragraph.
■ All wiring and electrical components must be installed by a qualified electrician.
■ Provide a main switch or other disconnection devices in the system in accordance with local laws and regulations.
■ Use a dedicated power line.
■ Install fuses (or circuit breakers) and power cables that match the maximum electrical current of the unit.
■ Install a differential switch according to local laws and regulations. Failure to install a differential switch can result in electric shock and fire.
■ Install a differential switch with the following characteristics:
- intervention value equal to 30 mA
- trip time less than 0.1 s
■ Make sure all electrical connections are carried out properly. Use the specified cables and ensure that the terminal connections and cables are protected from water
and other external forces to avoid the risk of fire.
■ Accommodate the power supply and control cables so that the front panel can be mounted correctly and therefore do not force the cables themselves to avoid the
risk of fire or electric shock.
■ Do not compress the cables and make sure that they do not come into contact with the pipes and sharp edges. Ensure that no external pressure is applied to the
cables.
1. Opening the front panel
S ome components inside the boiler can reach high temperatures that could cause serious problems burns. Before carrying out any operation, wait for these compo-
nents to cool or alternatively wear suitable gloves.
To dismount the front panel of the indoor unit “15.7 Extraordinary maintenance and replacement of heat pump components” on page 91.
2. Make the connections referring to the functional electrical diagram present in this manual.
3. Proceed in reverse order to reassemble the front panel. Make sure that it is correctly attached to the upper fixing and completely resting on the side panels. The
head of the screw “A”, once tightened, must not be underneath the lower bending stop.
