SAFETY PRECAUTIONS
•
High voltages exist and are accessible in the controller.
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.
-- 2 --
•
Never clean the controller or mixer head while power is
applied to the system.
•
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.
•
Disconnect the AC power input line cord before connecting the
mixer head cable.
•
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.
•
Be sure speed control is fully counterclockwise before the
POWER switch is placed in the FWD or REV positions. (50007-
00 Controller)
•
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 at full speed and load at higher ambient
temperatures, the mixer head may get very hot to the touch.
•
Use of mixing shafts and impellers larger than those
recommended could result in poor product performance and
shortened service life.
•
Mixer shafts must be inserted into high-speed through-shaft
mixers at least 3 inches (8 mm) and the collet hand-tightened
firmly to ensure adequate shaft retention. Keep mixer shafts 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.
