WARNING! Before establishing the electrical
connection, make sure that the power supply
is off. Also ensure that it is not possible to
reconnect the power during the operation.
WARNING! In the case of a unit with ducts, the
load loss from the exhaust duct must be less
than 100 Pa.
to reach the head required by the system for conditioners
with fans carrying a Ce marking, the input voltage percentage
can be adjusted from the user terminal (A).
to select the voltage percentage to be applied, carry out
the following procedures:
•
on the user terminal press the PRG button;
•
using the UP or DOWN key select SERVICE MENU
and confirm using the ENTER key;
•
enter the password (see the envelope attached to the

•
using the UP or DOWN key select EVAPORATING FAN
and confirm using the ENTER key;
•
set the amount and confirm using the ENTER key.
