WARNING
Poor fluidisation causes hot spots, heater failure, and damage to other parts.
Follow instruction book carefully. For correct fluidisation, pay attention to;
INSTALLATION
Ensure bath is level and air supply is adequate.
OPERATION
Adjust air valve for even fluidisation.
Do not insert objects larger than recommended.
Ensure objects do not lie in contact with container wall or porous plate.
MAINTENANCE
Regularly inspect and maintain air filter to eliminate oil vapour in air supply.
ALUMINA
Should the fluidised bath be stirred for a long period 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 portion of the charge then dry the whole
charge as above.
FUME EXTRACTION
When used for processing items which may emit toxic or inflammable fumes, it is
essential that an adequate fume extraction system be installed. The extraction system must
be correctly sized to ensure that any toxic fumes are removed from the working environment.
To eliminate the risk of spontaneous ignition, the concentration of inflammable
fumes above the bath and within the exhaust duct work must be kept below the lower explosive
limit.
