Adjust the rotational speed of the stirrer by turning the Fluid Stir Control Dial 2.
clockwise (to increase the speed) and/or counterclockwise (to decrease the
speed).
To deactivate the stirrer, rotate the Fluid Stir Control Dial counterclockwise. 3.
The magnetic stirrer may be turned on or off at any time for procedural purposes, but
in general, the unit should not be operated without stirring. If the reservoir fluid is not
agitated, the fluid may exhibit thermal variations. SP Scientific recommends setting
the Fluid Stir control dial to its maximum speed at all times for optimal operation and
performance.
Note: Do not operate the magnetic stirrer without fluid in the reservoir.
Powering Off
To power off the CharpyCool™:
Toggle the on/off breaker switch to the Off position. 1.
The green indicator light will turn off and the CharpyCool™’s refrigeration 2.
system compressor(s) will stop.
Note: When the CharpyCool™ is not in use, ensure that the bath reservoir lid is closed to
prevent evaporation of the cooling fluid.
Restarting
Due to the nature of the refrigeration system and its compressor, the CharpyCool™
should never be restarted immediately after it is powered off. SP Scientific
recommends waiting approximately five (5) minutes between shutting down and
restarting the CharpyCool™.
