SAFETY PRECAUTIONS
•
High voltages exist and are accessible in the power supply.
Contact Cole-Parmer for servicing.
•
Do not operate mixers where explosive vapors or flammable materials exist. Death or serious injury could result. Check NEC and local codes before installing.
•
Never clean the controller or mixer head while power is applied to the system power supply.
•
Use only those mixer shafts that are properly sized for the mixer head being used. Refer to mixer head specifications for the proper shaft diameter or range to be used. Sizes other than those specified can cause injury to personnel or damage to equipment and result in poor product performance and shortened service life.
•
Disconnect the AC power input line cord before connecting the mixer cable.
•
Be sure speed control is fully counterclockwise before connecting power to the mixer.
•
Exercise extreme care when adjusting mixer height and/or position to avoid personal injury. Never make these adjustments while the mixer shaft is rotating.
•
Never insert or remove the mixer shaft/impeller while the mixer shaft is rotating.
•
Check that all cords are clear of any moving parts and not subject to splashes or spills.
•
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 the mixer at full speed and load at higher ambient temperatures, the mixer head may get very hot to the touch.
•
Keep mixer shaft as short as possible to reduce resonant vibrations caused by the shaft flexing at higher speeds.
•
The mixer head is to be used only for mixing. It is not intended for any other purpose.

INTRODUCTION
The Stir-Pak 04555-00 mixing system covered in this manual consists of a combined mixer head and analog controller for 115VAC operation.
04555-00 STIR-PAK CONTROLLER
The variable-speed controller, Figure 1, is used to turn on and set the speed of the mixer head and provides a 100:1 adjustment range.
Figure 1
The controller ensures accurate, dependable motor speed (mixing) control, with “soft-start” and smooth, gradual adjustment to the speed setting. Constant speed with a 100:1 adjustment range is maintained electronically via automatic compensation for changes in load torque demands at both high and low speeds. Built-in motor current compensation minimizes speed drift with changes in load. Motor current limiting protects the system in case of a locked rotor condition. Output circuit protection protects against inadvertent output shorting.
INSTALLATION AND SETUP PROCEDURES
The mixer is equipped with a 5 ″ mounting rod. The mounting assembly is designed to be attached to an optional mixer support stand. Components supplied as part of the mixer package include the following:
• General-purpose mixer with integrated controller and 6-ft cable
• Power supply with 6-ft line cord
• Three-jawed chuck
• 12 ″ x 3/8 ″ stainless steel shaft
• 1.5
″ stainless steel propeller
• Support rod and double (rod) clamp

Installation of Support Rod
•
Never insert or remove the mixer shaft/impeller while the mixer shaft is rotating.
Attach mixer head to support rod, as shown in figure 2, using hex drive screw and lock washer provided:
Figure 2. Mixer with Support Rod attached
Note: The mixer is now ready to be attached to a support stand or to a tank clamp (not supplied).
Recommended stands, tank clamps, and a double (rod) clamp are available through Cole-Parmer.
Part numbers are listed in the ACCESSORIES section.
Installation Using a Support Stand
1. Set up support stand in accordance with the manufacturer’s instructions.
2. Attach a double (rod) clamp to the vertical rod on the support stand and tighten clamp screw.
3. Slide rod of mixer into clamp and secure with clamp screw.
4. Select an impeller and shaft for the required operation and install as follows: a. Place impeller on shaft and tighten set screw. b. Slide the shaft of the stirring device into the three-jawed chuck and tighten chuck.
5. Place support stand legs around vessel. Tilt angle is adjustable from 0 to 30 degrees.
•
Exercise extreme care when adjusting mixer head height and/or position to avoid personal injury. Never make these adjustments while the mixer shaft is rotating.
6. Position the height of the mixer head by moving the clamp up or down on the support stand.

Figure 3. Typical mixer setup using a support stand
Note: The power supply can be placed on any flat surface within six feet of the mixer.
•
Check that all cords are clear of any moving parts and not subject to splashes or spills.
7. Connect the 6-ft cable between the mixer head and the power supply.
8. Check that the controller is in the “0” or off position.
9. Connect the 6-ft line cord from the power supply to the appropriate 3-wire, grounded power source.
•
Be sure the SPEED control is fully counterclockwise.
The mixer is now ready to operate.

STIR-PAK MIXER OPERATION
POWER Indicator Mixer Head
The green LED indicator illuminates whenever the SPEED control is turned past 1.
POWER Indicator Power Supply
The green LED indicator illuminates whenever the power supply is energized.
SPEED Control
The SPEED control precisely sets the output speed of the shaft. The controller has a range of 100:1 depending on the shaft; speed can be as low as 40 rpm or as high as 4000 rpm.
Slowly adjust the SPEED Control from the 0 or OFF position to a setting that provides the desired mixing speed. The controller will ramp up the mixing speed to match the setting of the control.
Always return the speed control to the 0 or OFF position when mixing is complete.
•
To stop the mixer in an emergency, place the SPEED control switch in the 0 or OFF position or remove the power plug.
•
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 the mixer 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.
Note: With new mixers, allow approximately 20 minutes run-in time to allow warm-up drift to become minimal.
Over-Current Indicator
The green LED indicator will change to a flashing red when the mixer control senses an over-current situation. Over-current faults can be caused by too much load (torque) on the mixer or by a locked motor condition. The mixer will remain in a stopped position until the unit is turned off and back on again.
Over Temperature Indicator
The green LED indicator will change to a flashing amber when the mixer control senses an over-temperature situation. An over-temperature fault is caused by long running time at high loads.
The mixer will remain in a stopped position until the unit is turned off and back on again after it has time to cool down.
