CAUTION
DISCONNECTING THE UNIT FROM
THE MAIN POWER SUPPLY
These units must be connected to the
main electrical power supply through a
circuit-breaker or switch fuse with an
appropriate capacity and with a minimum
separation between the contacts of 3mm.
If this is not possible, a contact/container
combination equipped with an active
earth wire must be used. The contact
must have easy access after installation.
The contact must be disconnected from
the receptacle to ensure that no electrical
power gets to the unit. It is vitally
important to follow the safety standards
in force at the connection location and
also to check that the electrical power
supply is actively equipped with an earth
cable.
WARNING
Do not attempt to disconnect the unit
at the main power switch. Always use
the unit’s control when you want to
disconnect the system.
1) Do not spray flammable aerosols near
to the unit. The unit may be damaged if it
comes into contact with gasoline, solvents,
benzene, insecticides or other chemical
substances.
2) To prevent electric shocks, never splash
water into either the indoor or outdoor
units.
3) Do not insert your hands or fingers, or place
objects inside the air discharge grille of the
outdoor unit, because the fan rotates at
very high speeds, which may cause
serious personal injury.
