GROUNDING INSTRUCTIONS
This appliance must be grounded. If it should malfunction or break-
down, grounding provides a path of least resistance for electric cur-
rent to reduce the risk of electric shock. This appliance is equipped
with a cord having 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 ordinances.
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.
This appliance is for use on a nominal 120- Volt circuit, and has a
grounded plug that looks like the plug illustrated in sketch A above.
12
A temporary adapter that looks like the adapter illustrated in sketch-
12
es B and C may be used to connect this plug to a 2-pole receptacle
–
as shown in sketch B if a properly grounded receptacle is not avail-
able. The temporary adapter should be used only until a properly
grounded outlet (sketch A) can be installed by a qualified electrician.
The green colored ear, lug, or the like 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: In Canada, the use of a temporary adapter is not permitted by
the Canadian Electrical Code.
