ELECTRICAL: 
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. 
GROUNDING INSTRUCTIONS: 
This appliance must be grounded. If it should 
malfunction 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 
ordinances.

The D250 is for use on a nominal 115-volt circuit, and 
has a grounded plug that looks like the plug in “Fig. A”. 
A temporary adaptor that looks like the adaptor 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 adaptor 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 the like extending from the 
adaptor must be connected to a permanent ground 
such as a properly grounded outlet box cover. 
Whenever the adaptor is used, it must be held in place 
by a metal screw. 
The D250IE is for use on a nominal 230-volt circuit. 
Warning: 
Using the incompatible chemicals listed above will 
damage the machine. Damages of this type are 
not covered under the 6-3-1 warranty. Carefully 
read ingredients on manufacturer's label before 
using any product in this machine. 
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.
