Connecting the electricity supply cable to the mains
If the appliance is being connected directly to the
electricity mains an omnipolar switch must be installed
with a minimum opening of 3 mm between contacts.
! The installer must ensure that the correct electrical
connection has been made and that it is fully compliant
with safety regulations.
Before connecting the appliance to the power supply,
make sure that:
• The appliance is earthed and the plug is compliant
with the law.
• The socket can withstand the maximum power of
the appliance, which is indicated on the data plate
located on the appliance itself.
• The voltage falls within the range of values indicated
on the data plate.
• The socket is compatible with the plug of the
appliance. If the socket is incompatible with the
plug, ask an authorised technician to replace it. Do
not use extension cords or multiple sockets.
! Once the appliance has been installed, the power
supply cable and the electrical socket must be easily
accessible.
! The cable must not be bent or compressed.
!
The cable must be checked regularly and replaced
by authorised technicians only.
!
The manufacturer declines any liability should
these safety measures not be observed.
! Do not remove or replace the power supply cable
for any reason. Its removal or replacement will void
the warranty and the CE marking. INDESIT does not
assume liability for accidents or damage arising from
replacement/removal of the original power supply
cable. Replacement can only be accepted when
carried out by personnel authorised by INDESIT and
using an original spare part.
