Change ignition wire
1 To release the ignition wire (Pos. 24) on the ignition electrodes
(Pos. 23) are both 6- hexagon nuts (Pos. 13) using
spanner SW 5.5
2 Turn down the upper nut (Pos. 13I1)
3 To release the ignition wire to the ground electrode (Pos. 22)
crucible holders hold hex nut (Pos. 13/3) and solve with
spanner SW 5.5
4 Screw (Pos.25) and remove while holding the crucible holder
5 Remove old ignition wire iand attach new ignition wire
6 Ignition wire (Pos. 24) mounted as shown in figure on the
screw (Pos.25)
7 Screw in screw (Pos.25) into the crucible holder, screw hex nut
(Pos.13/3) on the screw
8 Complete unit (Pos. 25, 24,10,13) srew in the ground electrode,
until the screw the ignition wire clamps
9 Align the crucible holder, no contact to the ignition electrode,
with hexagon nut on the ground electrode counter
10 Align the lower nut on the ignition electrode (Pos.13/2) so that
the ignition wire is horizontal
11 Ignition wire (Pos. 24) on ignition electrodes (Pos. 23) mount
12 Screw the upper hex nut (Pos. 13/1) and tighten the ignition
wire with two nuts by counter holding the lower nut
Change ignition electrode
1 Loosen ignition wire at the ignition electrode as described
previously
2 Hex nut (Pos. 12) and remove on the bottom of the inner
vessel bottom (Pos. 2) loosen with the spanner and screw
down SW7
3 Ignition electrodes (Pos. 23) by pulling it upwards
4 Take O-ring (Pos. 3) and replace with a new one
5 Install new ignition electrode in reverse order, making sure
that the insulating bushing (Pos. 6) located in the inner vessel
bottom
6 Tighten hex nut (Pos.12) by hand
Caution: Risk of short circuit at the nut is tightened
too strong
Change the main seal
1 Remove O-ring with a suitable non-sharp tool
The O-ring can be removed with your fingers, pull the O-ring to
two fingers apart, thus it is pulled out of the groove. Now it can
be removed with your fingers.
Note: Rub the new O-ring before inserting it into the groove with
O-ring grease (O-ring grease supplied).
This facilitates the closing of the C 1 considerably!
