WARNING
Poor fluidization causes hot spots, heater failure and damage to other parts. Follow this Instruction Manual
carefully. For correct fluidization, pay attention to the following:
INSTALLATION
•
Ensure the bath is level and air supply is adequate.
OPERATION
•
Adjust air valve for even fluidization.
•
Do not insert objects larger than recommended.
•
Ensure objects do not lie in contact with container wall or porous plate. Sample buckets and probe holders
are available.
MAINTENANCE
•
Regularly inspect and maintain the air filter to eliminate oil vapour in the air supply.
ALUMINA
•
Before handling the alumina, consult the MSDS for safe handling. Contact
you require a copy.
•
The principle risk is related to the concentration of dust in the air acting as a nuisance dust.
•
Alumina is non-hazardous but dust may irritate the eyes and the respiratory system and cause skin irritation.
•
Provide appropriate exhaust ventilation at places where dust is formed.
•
For storage: protect from moisture. Avoid dust formation. Keep container tightly closed. Store in a well-
ventilated place. Guard against dust accumulation of this material.
•
Wear correct PPE whilst handling the Alumina material. Wear safety glasses with side shields, appropriate
chemical resistant gloves and suitable protective clothing.
•
Should the fluidized bath be stored for a long period under damp or humid conditions, moisture may be
absorbed by the alumina which is hydroscopic. To avoid violent fluidization 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 FLUIDIZATION
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.
