STIR-PAK CONTROLLER OPERATION
FWD-OFF-REV Switch
In the FWD position, the shaft will rotate in a
counterclockwise direction when viewed from
the impeller.
The center or OFF position removes power from
both the controller and mixer head.
In the REV position, the shaft will rotate in a
clockwise direction when viewed from the
impeller.
POWER Indicator
The green LED indicator illuminates whenever
the FWD-OFF-REV switch is in either the FWD
or REV position.
SPEED Control
The SPEED control precisely sets the output speed of the shaft. The controller has a range of 100:1
depending on the model; shaft speed can be as low as 2RPM or as high as 6000RPM.
Slowly adjust the SPEED Control from the 0 position to a setting that provides the desired mixing speed.
Always return the speed control to the 0 position when mixing is complete.
Note:
With new mixing heads, allow approximately 20 minutes run-in time to allow warm-up drift to
become minimal.

•
To stop the mixer head in an emergency, place the FWD-
OFF-REV switch in the OFF position or remove the power
plug.
•
Be sure the SPEED control is fully counterclockwise before
the POWER switch is placed in the FWD or REV positions.
•
Use care when setting the operating speed of the mixer.
Operation at high speeds in small mixing vessels could
result in hazardous splashing on the operator and
equipment.
•
When running at full speed and load at higher ambient
temperatures, the mixer head may get very hot to the touch.
•
Never insert or remove the mixer shaft/impeller while the
mixer shaft is rotating.
causes the mixer motor shaft to rotate at the previously
programmed speed. Depressing the stop button
stops the motor. Changing Display Modes
(TIME , RPM, TORQUE) is accomplished by pressing the desired mode button once.
Additional operation of the mode button advances operation to the set mode.
