GROUNDING INSTRUCTIONS
When using electric appliances, basic precautions
The beverage/ice machine must be grounded in
accordance with national and local electrical codes.
This appliance must be grounded. In the event of
malfunction or breakdown, grounding provides a path of
least resistance for electric current to reduce the risk of
electric shock. This appliance is equipped with a cord
having an equipment-grounding conductor and a
grounding plug. The plug must be plugged into an
appropriate outlet that is properly inst alled and grounded
in accordance with all local codes and ordinances.
Improper connection of the equipment-grounding
conductor can result in a risk of electric shock. The
conductor with insulation having an outer surface
that is green with or without yellow stripes is the
equipment grounding conductor. If repair or
replacement of the cord or plug is necessary, do not
connect the equipment-grounding conductor to a
live terminal. Check with a qualified electrician or
serviceman if the grounding instructions are not
completely understood, or if in doubt as to whether
the appliance is properly grounded. Do not modify
the plug provided with the appliance — if it will not fit
the outlet, have a proper outlet installed by a
qualified electrician.
must always be followed, including the following:
a. Read all the instructions before using the
appliance.
b. To reduce the risk of injury, close supervision is
necessary when an appliance is used near
children.
c. Do not contact moving parts.
d. Only use attachments recommended or sold by
the manufacturer.
e. Do not use outdoors.
f. For a cord-connected appliance, the following
shall be included:
• Do not unplug by pulling on cord. To unplug,
grasp the plug, not the cord.
• Unplug from outlet when not in use and
before servicing or cleaning.
• Do not operate any appliance with a
damaged cord or plug, or after the appliance
malfunctions or is dropped or damaged in any
manner. Contact the nearest authorized
service facility for examination, repair, or
electrical or mechanical adjustment.
g. For a permanently connected appliance — Turn
the power switch to the off position when the
appliance is not in use and before servicing or
cleaning.
h. For an appliance with a replaceable lamp —
Always unplug before replacing the lamp.
