Installation In The Laboratory; Environmental Operating Conditions - Fisher Scientific Power Overhead Stirrer Manuel D'instructions

Installation in the Laboratory

1. The stirrer must be securely fi xed to a stable support - e.g. clamped to an original
Fisher Scientifi c stand that is on a stable, level surface. See Safety Instructions.
CAUTION:
WARNING:
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 fi rmly tightened. Open the chuck fully to prepare for impeller attachment.
3. Impeller attachment:
Insert the impeller shaft 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.

Environmental Operating Conditions

The stirrer 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 specifi cations.
5. Pollution degree 2 in accordance with IEC 664
This is not an explosion-proof stirrer. Do not use
with highly fl ammable or explosive materials.
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.
"Normally only non conductive pollution occurs.
Occasionally, however, temporary conductivity caused by
condensation must be expected"
