6.5.7 Replacing the furnace door (only for devices with serial
numbers < 5000)
WARNING
Risk of burning
The furnace door may be hot.
➢ Check the temperature of the furnace on the display.
➢ Change furnace doors only in the cold state.
The furnace door must be changed when sintering oxide ceramics. The
argon supply pipe for the furnace door with gas socket must also be
removed.
Please proceed as follows to change the furnace door:
1. To disconnect the pipe socket for the argon supply, push the retainer
ring for the argon socket towards the furnace enclosure.
2. Pull the argon supply pipe of the furnace door with gas socket out of
the socket.
DANGER
Danger of suffocation
If the pipe remains in the socket when sintering oxide ceramic materials,
then argon escapes from the base plate of the furnace door with gas
socket during the sintering process.
3. On the lower side of the furnace door there is a guide pin for locking
the door with the furnace fastening clamp. To unlock the guide pin,
pull this downward and then turn the pin in a counter-clockwise
direction.
 The pin is now unlocked and stopped.
4. Pull the furnace doors forward and out of the fastening clamp.
