Operating Precautions
The SPRINT® System must be grounded. In the event of an electrical short circuit, grounding reduces the risk of electric
shock by providing an escape wire for electric current. This instrument is equipped with a cord having a grounding wire
with a grounding plug. The plug must be plugged into an outlet that is properly installed and grounded. Consult a qualifi ed
electrician or service technician if the grounding instructions are not completely understood or if doubt exists as to whether
the instrument is properly grounded. If it is necessary to use an extension cord, use only a 3-wire extension cord that has
a 3-blade grounding plug and a 3-slot receptacle that will accept the plug from the instrument. The marked rating of the
extension cord must be equal to or greater than the electrical rating of the instrument.
This instrument utilizes high voltages. Only those trained in repair and maintenance of high voltage systems should
perform instrument service and repair. Ensure that the instrument power cord is removed either from the electrical outlet
or the back of the instrument prior to any maintenance or service and prior to opening the instrument cover.l
Use of the Sprint instrument in any manner not specifi ed by CEM Corporation could render the instrument opera-
tion unsafe for the operator.

WARNING
If damage to the instrument is noted upon receipt, do not attempt to operate the instrument.
This instrument utilizes high voltages. Only technicians trained in repair and maintenance of high voltage
systems should perform instrument service and repair.
Disconnect the instrument from the AC power source prior to performing any maintenance or service pro-
cedure requiring removal of the instrument top cover.
CAUTION
Control for the bottle stirrer and external balance is through cables that connect directly to the Sprint sys-
tem. These connectors should be connected or disconnected only with the Sprint power switch in the “off”
position. If the bottle stirrer cable or balance cable is connected with the system on, damage to the I/O
board may occur.
