EARTHING:
Check the earth cable is connected to the
earthing system of the building itself. Ensure
that a suitable differential switch is installed for
earthing purposes. Do not connect the earth
cable to the gas or water pipes, to the lightning
conductor, or to the earth cable of the telephone.
WARNING:
• Water pipes:
Some parts of the water pipes are
made of plastic materials and are not suitable for
earthing.
• Gas pipes:
If there is an accidental electrical
discharge from the air conditioner, it could easily
cause a fire or even an explosion.
with a minimum contact gap of 3mm on both poles.
• Check the earth cable is connected to the earthing
system of the building itself.
• For the power supply, use undamaged cables with a
section that is suitable for the load (for information
on sections refer to the table provided in this
manual).
• Do not make connections on the power supply
cable: use a longer cable. Junctions can cause
overheating and/or fires. Do not repair damaged
cables: replace them with new cables with a suitable
section. Have repairs carried out by “Personnel with
specific technical skills”.
• The wiring diagrams are subject to continuous
updates, so it is essential to use those on the
machine as your reference.
• Ensure that the air conditioner is connected to the
power supply or to a power socket with the correct
voltage and frequency. Using power supplies with
the incorrect voltage and frequency could damage
the unit and consequently risk starting a fire. The
voltage must be stable, without major fluctuations.
• The installation must be carried out in compliance
with the national standards relating to electrical
systems, wiring and safety.
