InstallatIOn
Avoid siting the FB-08 in a laboratory environment which contains instruments that are sensitive to dust.
Although the fluidised bath has its own dust extraction system, a small amount of fine dust may still be
emitted during operation.
power
The FB-08 requires a power supply of 240V 50/60Hz at 3KW; thus it can be run from a standard 13A
socket.
Before connecting to the main supply check the voltage with that marked on the rating plate. Connect
the mains cable to a suitable supply as follows:
Connection 240 V
Live Brown
Neutral Blue
Earth Green/Yellow
air
The FB-08 is supplied with integral filters and regulators suitable for normal clean dry air line supply between
60 and 125 lb/in
2
. If the air supply is excessively dirty Techne can supply an additional external filter/regulator
assembly which, if used, must be adjusted to its maximum setting of 60 lb/in 2 . The air supply should be
connected via suitable flexible hose to the hose tail at the rear of the left hand end of the bath.
Mechanical
The unit should be mounted on a firm level surface. Normal operation only requires access to the front of
the units but periodic maintenance and servicing requires access to the left hand side also; this should be
borne in mind when positioning the unit initially.
A bubble level (25) is built into the frame at the base of the front panel; this should be accurately levelled
by adjusting the four corner feet (10). After final adjustment, all four feet should be firmly grounded and
the unit should be level. Failure to do this can impair the operation of the unit. The surface should also
be heat resistant.
alumina
Fill the bath with sufficient of the alumina supplied so that it is 150mm (6") below the top surface of
the unit before it is fluidized. The dust extraction system should be turned on during filling in order to
minimise the amount of dust given off.
Should the fluidised bath be stored for long periods of time under damp or humid conditions, moisture
may be absorbed by the alumina which is hydroscopic. To avoid violent fluidisation which occurs when
damp alumina is heated above 100°C, operate the bath for a period of approximately 8 hours at 90°C
prior to operation at elevated temperatures.
NEVER ADD COLD OR DAMP ALUMINA TO A HOT BATH AS THIS WILL ALSO CAUSE VIOLENT FLUIDISATION
WHICH CAN BE DANGEROUS. Allow the bath to cool then add the fresh alumina. If this fresh alumina is
a large proportion of the charge then dry the whole charge as above.
