TECHNICAL DATA
If the power cable is damaged, contact a
qualied company (e.g. the Authorised
Technical Assistance Centre) for its re-
placement to avoid a hazard.
e power cable must follow the prescribed route (Par. 1.8); avoid-
ing contact with the side of the frame.
If the fuses on the circuit boards need to be replaced, this must also
be done by qualied personnel: use a F3.15A H250V fuse on the
P.C.B.
For the main power supply to the appliance, never use adapters,
multiple sockets or extension leads.
Make the various electrical connections according to your needs
(Fig. 10, 11):
Connect the relative terminals 37 and 38 to electrically
connect the indoor unit and the storage tank unit, re-
moving heating element R8 in the instrument (Fig. 10):
Outdoor unit electrical connection

terminals F1 and F2 as shown in the wiring diagram (Fig. 11). e
outdoor unit is powered at 230 V, regardless of the indoor unit.
Congure the indoor unit parameters as indicated in paragraph
(Parag. 3.13).
Photovoltaic system installation
Connecting the product to a photovoltaic system enhances use of
the outdoor unit when the photovoltaic panels are operating. Car-
ry out the connection as indicated (Fig. 10).
Dehumidiers
Carry out the connection as indicated (Fig. 11). To complete the
connection operations, insert the 2-relay Board optional kit.
It is compulsory to set up separate lines
with dierent power supply voltages,
particularly it is essential to separate the
very low voltage connections from the
230 V ones.
No product pipes must ever be used to
earth the electric system or telephone
lines.
Ensure elimination of this risk before
making the indoor unit electrical con-
nections.
e indoor unit can be electrically con-
nected to outdoor units with very low
voltage safety circuits (SELV)
