Grounding Instructions
THIS PRODUCT IS FOR COMMERCIAL
USE ONLY.
Electrical:
In the USA this machine operates on a standard 15
amp 120V, 60 hz, A.C. power circuit. The amp, hertz,
and voltage are listed on the data label found on each
machine. Using voltages above or below those
indicated on the data label will cause serious damage
to the motors.
Extension Cords
:
If an extension cord is used, the wire size must be at
least one size larger than the power cord on the
machine, and must be limited to 50 feet (15.5m) in
length.
Grounding Instructions:
This appliance must be grounded. If it should malfunc-
tion or break down, 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
grounding plug. The plug must be inserted into an
appropriate outlet that is properly installed and
grounded in accordance with all local codes and ordi-
nances.
120 Volt Models:
This appliance is for use on a nominal 120-volt circuit,
and has a grounded plug that looks like the plug in "Fig.
A". A temporary adapter that looks like the adapter in
"Fig. C" may be used to connect this plug to a 2-pole
receptacle as shown in "Fig. B", if a properly grounded
outlet is not available. The temporary adapter should
be used only until a properly grounded outlet (Fig. A)
can be installed by a qualified electrician. The green
colored rigid ear, lug, or wire extending from the
adapter must be connected to a permanent ground
such as a properly grounded outlet box cover.
Whenever the adapter is used, it must be held in place
by a metal screw.
NOTE: Adaptors are not allowed in Canada.
Improper connection of the equipment-grounding
conductor can result in a 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.
