Carbolite ABA 7/35B - Manual (Page 19)

19 MF60 – 1.04
5.3 General Operating Notes
Heating element life is shortened by use at temperatures close to maximum. Do not leave the
ABA at high temperatures when not required. The maximum temperature for the main chamber
is 750°C (1380°F) and is factory set for the after burner at 900°C (1652°F)
The chimney and should always be correctly fitted and unobstructed (see Fig 3.4.1)
See section 20 for information about maintenance
5.4 Operator Safety
The ABA incorporates a safety switch which interrupts the heating element
circuit when the door is opened. This prevents the user from touching a live
heating element, but also prevents heating up if the door is left open.
When a test is started the door is automatically locked until a constant weight
loss (end-point) is achieved. This is to prevent the user from opening the door whilst volatiles
are being driven off from the test sample. If the door were to be opened during this time the
addition of air could cause the volatile materials to ignite in an explosive manner.
The red sample basket cover must be used to cover the hot sample baskets
whilst they are allowed to cool.
Before removing any hot objects from the chamber make sure that you have a
safe place to put them down. Do not place hot objects on inflammable surfaces.
Wear appropriate safety clothing; gloves, mask and safety glasses are
recommended.
