1. The stirrer must be securely fixed to a stable support - e.g. clamped to an original
Caframo stand that is on a stable, level surface. See safety instructions on page
3.
CAUTION:
This is not an explosion-proof stirrer. Do not use
with highly flammable or explosive materials.
WARNING:
Be sure that the unit's voltage is the same as the
supplied voltage. Information on the unit's voltage
and current are located on the serial plate.
This unit must always be connected to a grounded
electrical outlet.
2. Chuck removal and attachment:
Loosen the set screw with the allen key found on the chuck key. Remove chuck.
To attach align the set screw with the pilot hole on the shaft. Tighten the set
screw with the allen key found on the chuck key. Make sure that the set screw
is firmly tightened. Open the chuck fully to prepare for impeller attachment.
3. Impeller attachment:
Insert the impeller shaft (see accessories) into the open chuck and adjust the
impeller to a maximum length of 25 cm (10 inches) [of a 40 cm (16 inch) shaft]
to reduce vibration. The hollow shaft allows the impeller shaft to come through
the top of the stirrer if necessary. Tighten the chuck's outer ring by hand and
then secure with the chuck key. Install the chuck guard over the chuck.
All BDC stirrers must operate in the following conditions:
Indoors
1. Altitudes below 2000 meters.
2. Temperatures from 5 °C to 40 °C
3. Maximum relative humidity 80% for temperatures up to 31 °C decreasing
linearly to 50% relative humidity at 40 °C.
4. Mains supply as indicated under the technical specifications.
5. Pollution degree 2 in accordance with IEC 664
"Normally only non conductive pollution occurs.
Occasionally, however, temporary conductivity caused by
condensation must be expected"
