SAFETY INSTRUCTIONS
(read carefully)
Failed observance of the safety instructions may
compromise the operation of the system or
seriously damage it. The following “safety instruc-
tions” contain essential indications for the system’s
safety and for the safety of the people using it.
System’s safety prearranged during its
production
The vacuum cleaner was made paying particular
attention to the safety of operators. Each compo-
nent was designed on the basis of strict safety
guarantees which Disan has adopted.
Electrical safety
F
Connect the central vacuum cleaner only to a
current with the same tension indicated on the
“identification data” plate (see chapter “IDENTI-
FICATION DATA”, page 18) .
F
Establish the electrical connection provided
with efficient grounding and with a neutral
phase.
F
The safety of the electronic system is guaran-
teed only if there is a suitable safety ground
fault circuit-breaker complying with the regula-
tions in force.
!WARNING!
For models with electronic inverter it’ s necessary
to provide a safety switch (FI) of 300mA at least.
