The condensate is removed from the pan located underneath the
coil through a hose with drain trap, already fitted in the unit; the
end of the hose should be connected to the sewerage system in
the building via a rubber or plastic hose with an inside diameter
of 20 mm.
If the air-conditioner is fitted with a humidifier, the condensate is
drained from the humidifier pan, excluding Over units (see the
following paragraph).
During installation, pour water into the condensate collection pan
so as to fill the drain trap inside the unit with water.

-
Check that the mains voltage
corresponds to the rated val-
ues for the unit (voltage, no. of phases, frequency) shown on the
electrical panel.
-
The power supply voltage must be between
± 10% of the
rated value: operation at voltages outside of these limits may
void the warranty.
-
Fasten the ends of the power cable
to the terminals on the
main switch inside the electrical panel; fully tighten the screws.
Connect the yellow-green earth wire to the special terminal
marked 'PE'.
ACCESS TO THE BOARD
To access the board, open the front panel and the thermoformed
cover on the electrical panel.
The electronic components are sensitive to discharges of static
electricity from the human body. Touch an earthed object before
handling any electronic component.
Warning:
All work must be performed, components select-
ed and materials used in complete accordance with the legis-
lation in force in material in the country concerned, and con-
sidering the operating conditions and intended uses of the
system, by qualified personnel.
If local and national standards require installation of a
residual current circuit breaker upstream, use a type B
device with threshold Id=300 mA.
Choose a model that features:
- High frequency current filtering
- Timer to help prevent disconnection due to the load of
stray capacitance on start-up.
Before starting the unit, check the tightness of all the
electrical connections and cables on the unit, as these
may have come loose during handling and transport.
ACCESS TO THE ELECTRICAL PANEL AND CABLE
INLETS
Before performing any work on the electrical parts, make sure
that there is no live voltage and that the disconnecting switch is
open (position “O”);
The power section of the electrical panel is protected by a plastic
screen; to remove the screen, open the main switch and remove
the fastening screws.
