Heating Element Replacement; Temperature/Pressure Rate - VWR VAPOUR-Line lite serie Bedienungsanleitung

To prevent this corrosion, all aluminium autoclaves are equipped with a special device called
11acrificial body (Cat. No. 481-0721). This device is a small disc fixed with a screw to the vessel
body and is made of a metal that is more easily oxidised then aluminium. This means that the
galvanic current will flow through the sacrificial body which will be corroded instead of the
autoclave vessel. If the sacrificial body has been completely worn out, the autoclave vessel will
begin to corrode, so it is mandatory to periodically check the sacrificial body status and replace it
before it wears out. It is advisable to order some spare sacrificial bodies in order to always run
the autoclave with a sacrificial body in it.

Heating element replacement

Disconnect the electric supply, unscrew the two fixing nuts on the outside bottom of the sterilisation
chamber and insert a new heating element. To re-assemble, repeat the same steps in reverse order.
Ensure that the water level in the sterilisation chamber always covers the heating element.
