conditioner must be grounded.
Insufficient grounding may
cause electric shocks.
• Do not connect the grounding
wire to gas pipes, water
pipes, lightning conductors
or telephone grounding wire.
After mounting, the appliance
should be powered up in order
to determine grounding leak
check. If you neglect, it may
cause electric shocks and
damages to the product.
• WARNING: In order to
prevent possible electric
shocks, a ground leak circuit
breaker with nominal capacity
should be installed.
• WARNING: The appliance
should be mounted by Vestel
Authorized Service according
to “Mounting Instructions”.

attached to the cable, and the
distance between its contacts
should not be less than 3.0
mm.
• WARNING: In the event
that your air conditioner is
connected permanently to
a fixed installation and has
a leakage current that may
exceed 10 mA, a leakage
protector with an operating
current not more than 30 mA
should be connected to the
fixed cable.
• For the use of the appliance

2
select an altitude of less than
2000 meters above sea
level in terms of insulation
distances.
