• The electric connections to the
control board must be made by
specialised staff according to
the diagram supplied.
• Make sure that the voltage and
the frequency stated on the
plate correspond with those of
the electric connection line.
• The use of adapters, multiple

is not allowed to power the
dehumidifier.
• It is the installer's responsibility
to assemble the unit as near as
possible to the power supply
isolator and the necessary to
protect the electric parts.
• Connect the unit to an efficient
earth socket, using the relevant
screw inserted in the unit itself.
• Use the cable gland (external
for horizontal versions, internal
for the recessed version) near
the panel to turn it on.
