Precautions:

 The Stirrer should be placed in a clean and dry environment. The ambient

temperature should not exceed 40˚C.

 Large fluctuations of voltage may cause an unstable speed, so if needed; use of a

regulated power supply is suggested.

 Avoid using the Stirrer in a severely corrosive environment.
 If the agitating medium is volatile and/or flammable, be cautious that electric sparks

may cause explosions or fires.

[4]

Installation: (Refer to Figure 1)

1. Place the Base (item #6) on a stable surface. Connect the two Vertical Support Rods
(items #7) by screwing them together.

2. Assemble the Vertical Support Rods into the Mounting hole in the Base. Secure to
base by using wrench provided to tighten nut.

3. Tighten the Support Clamp (item #8) to the upper end of the Vertical Support Rods.

4. Connect the Horizontal Holding Rod (item #9) to the Stirrer (item #1) by screwing into
threaded mounting hole located at the rear of the Stirrer. Then install the opposite end
of the Horizontal Holding Rod into the Support Clamp and tighten. The Stirrer can be
easily adjusted up / down, and in / out by carefully loosening and tightening the Support
Clamp.

5. When ready to use Stirrer - Install the Stirrer Propeller (item #5) by using the Chuck
Key provided to loosen and tighten the opening for the Chuck (item #4).

Operation: (Refer to Figure 1)

 Before testing or operating this Stirrer, please read all instructions carefully.

To ensure the running safety of the stirrer and personnel, be sure to inspect support
connections regularly.

The Stirrer should only be operated when installed on the Base. Hand held operation
is prohibited.

The Overhead Stirrer cannot be used in a flammable and/or explosive environment.

 Before plugging the power cord into the appropriate grounded electrical outlet, make

sure that the power switch (item #11) on the Stirrer is in the off position and the speed
control knob (item #13) is in the starting/slowest position.

1. A test run is recommended before use and the stirring propeller should not be installed
when testing.

2. After plugging the stirrer into the electrical outlet, turn on the power switch (item #11).
The power indicator lamp (item #10) will illuminate.

3. Slowly turn the speed control knob (item #13) clockwise to increase speed. The rpm
value in the digital display (item #12) will increase accordingly. Turning the speed
control knob counter-clockwise will decrease the speed.

[5]

4. To change the speed range from high speed to low speed or low speed to high speed,

Figure 2

the motor must be brought to complete stop. “I” is for low speed range; “II” is for high
speed range (See Figure 2). To change the speed range from high to low, turn shift
plate (item #3, in Figure 1) counterclockwise (looking down from the top) until in place,
then pull down, and finally turn clockwise to reset it. To change the speed from low to
high, turn shift plate (item #3, in Figure 1) counterclockwise until in place, then push up,

and finally turn clockwise to reset it. When it’s in place you can hear the “click” of the

Press Fit Ball Plunger.

NOTE: If the unit has not been used for some time, a knocking noise may be heard when
switching on. This is due to the preload on the friction lining of the friction wheel drive. This
has no detrimental effect on the function of the unit, and the knocking noise will disappear
after a short running-in period.

Maintenance and Service:

 Ensure Stirrer is unplugged before cleaning
 Do not allow moisture to get into the appliance when cleaning
 Wear protective gloves during cleaning the devices

Use to remove:
Dyes isopropyl alcohol
Construction materials water containing tenside/ isopropyl alcohol
Cosmetics water containing tenside/ isopropyl alcohol
Foodstuffs water containing tenside
Fuels water containing tenside

If a motor failure happens, check whether the power switch is on and the unit is plugged in.
Verify that the power outlet is providing the correct voltage. If these faults are eliminated and
the motor failure remains, contact CG Life Sciences for service. The unit should not be
opened for any reason without proper authorization.
