INSTALLATION
Avoid siting the FSB-200-P-AC in a laboratory environment which contains instruments that are sensitive to dust.
Although the fluidized bath has its own dust extraction system, a small amount of fine dust may still be emitted
during operation.
Numbers in the text refer to Figure 2.
POWER
The FSB-200-P-AC requires a power supply of 230V, 50/60Hz at 3kW; please see section ELECTRICAL
INSTALLATION.
AIR
The FSB-200-P-AC is supplied with integral filters and regulators suitable for a normal clean dry air line supply
between 60 and 125 psi (414 to 862 kPa). If the air supply is excessively dirty Antylia Scientific can supply an
additional external filter/regulator assembly which, if used, must be adjusted to its maximum setting of 60 psi
(414 kPa). The air supply should be connected via suitable flexible hose to the compressed air inlet (14) 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
unit 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 spirit level (12) is built into the frame at the base of the front panel;
this should be accurately levelled by adjusting the four corner feet (13). 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
Turn on the dust extraction system (7) during filling to minimise the amount of dust given off. Fill the bath
chamber (1) with sufficient of the alumina so that it is approximately 200mm (8") below the top cover of the unit
before it is fluidized. Note that the alumina does exhibit expansion with fluidization and heat so you will need to
verify the level at your maximum operating temperature. When fluidized, the alumina level should be
approximately 150mm (6”) from the top surface of the bath at your maximum operating temperature. As shown
in Figure 3, the alumina is at the correct level when you just see the tops of the heaters.

When correctly fluidized, the surface of the alumina should be flowing with the motion like violently boiling
cream.
