CLARKE TECHNOLOGY Symphony Upright Vacuum Operator's Manual
GROUNDING INSTRUCTIONS
Preparation:
The following are instructions for connection to the
power supply and the electrical ground.
This machine must be connected to the electrical ground to
protect the operator from electrical shock. The machine has
an approved power cord with three conductors and a plug
with three terminals. Connect the plug to a receptacle that
has three holes and is connected to the electrical ground.
The green (or green and yellow) conductor in the cord is the
ground wire. Never connect this wire to any terminal other
than the ground pin terminal.
DANGER: Improper connection of
the equipment-grounding conductor can result
in risk of electric shock. Check with a qualified
electrician or service person if you are in doubt
as to whether the outlet 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.
This machine is for use on a 110 to 120 Volt AC 60 cycle
electric circuit. Make sure you have the correct frequency
and voltage before connecting the power cord to an outlet.
The machine has a plug as shown in figure A. If a receptacle
connected to the electrical ground as shown in figure A is not
available, use an adapter as shown in figure C. This adapter
must be connected as shown in figure B to an electrical
ground in the electrical outlet. Make sure you use the plate
screw and the tab to fasten the adapter.
WARNING: Always use this machine with an AC
three-conductor electrical system connected to
the electrical ground. Replace any worn, cut or
damaged cords. Replace any damaged plugs,
receptacles or connector bodies.
WARNING: Do not cut, remove, or break the
ground terminal. Do not try to fit a three-termi-
nal plug into a receptacle or connector body
that does not fit the plug, see your Authorized
ALTO Dealer to get an authorized person to
make the connection.
WARNING: Do not move the machine over an
electrical cord. Always lift the cord over the
machine.
EXTENSION CORDS:
Use only an approved extension cord with three conductors,
a plug with three terminals and a connector body with three
holes. This machine has a power cord with wire size 18
AWG (AWG means American Wire Gauge).
WARNING: If you use an extension cord, use an
extension cord with minimum wire size 16 AWG.
Do not use an extension cord longer than 50
feet. Do not join two extension cords.
