High temperature / Burning of the skin

Hot combustion tube

•

When the analyzer (HTF, resistance furnace) is switched on again after
switching off, the adjusted set point is driven immediately. Please
check this!

Fig 44: Removing the combustion tube

CAUTION: Unplug the mains power cable before opening this device!
1.

Switch off the furnace and disconnect the power plug.

Remove the oxygen tube (

Remove the plastic tube from the dust box (

) at the furnace outlet.

Dismantle the dust box by removing the screws (

) and remove the cover (

) using a

screw driver (

) if necessary.
