Care And Maintenance; Replacing The Crucible Holder; Replacing The Ignition Electrode; C 5010 Oxygen Valve Maintenance - IKA C 5010 Mode D'emploi

Care and maintenance

The work described in the following may only be performed by
personnel with professional training or IKA.
All work on the fittings of the decomposition vessel require a
leak test and new pressure testing.
Furthermore, reference is made to the regulation for pressure vessels
2014/68/EU.
Send in the case of service the equipment back in the original packaging.
Storage packing is not sufficient for the back dispatch. Use additionally a
suitable transpertation packing.

Replacing the crucible holder

• Remove ignition wire
• Firmly hold crucible holder and unscrew the hexagonal nut at the
upper end of the electrode in counterclockwise direction.
• Screw the crucible holder out of the cover.
• Insert new crucible holder and align it in such a way that that the slot
in the deflector is flush with the ignition electrode located opposite
(crucible holder toward the inside).
• Tighten locknut.

Replacing the ignition electrode

23 (C 5010)
• Remove ignition wire.
7 (C 5012)
• Unscrew electrode (item 20) in a
22 (C 5010)
counterclockwise direction using
6 (C 5012)
the double open-ended wrench
and holding up the female insert
contact (item 23) using a suitable
tool (item 20 screwed together with
item 23).
21
• Remove individual parts as shown in
20
the following diagram.
31 (C 5010)
• A new O-ring (item 21) (cf. O-ring
80 (C 5012)
set) should be used when the new
24 (C 5010)
electrode is inserted. 9 (C 5012)
• Join individual parts (items 20, 22
and 23) and screw together firmly.
31 (C 5010)
After being tightened the
80 (C 5012)
female insert contact (item
23) and insulating bushing
Note!
(item 22) have to be flush
with the recess in the cover.
Repeat procedure if required.

C 5010 oxygen valve maintenance

The oxygen valve is used to fill and empty the decomposition vessel. The
O-ring sealing may wear because of aggressive combustion gases, which
means that the decomposition vessel may not be tight.
24
In order to replace the O-ring the
valve inside the cover has to be
opened:
• Unscrew locking screw (item 15) using a
slotted screwdriver.
• Remove valve piston (item 16) and O-ring
(item 17).
• Replace O-ring (cf. O-ring set).
• Insert piston in such a way that the guide
pin point toward the locking screw.
• Tighten locking screw. 16

C 5012 oxygen valve maintenance

Disassembly of the oxygen valve for the and C 5012 decomposition
vessel is identical to the procedure for the C 5010 decomposition vessel.
However, the components differ in their design.
Pos. 3 valve piston
Pos. 4 pressure spring
Pos. 5 locking screw
Pos. 20 O-Ring
Assembly of the components shall be
performed as specified in the preceding
diagram.
The pressure spring (item 4) does thus the
oxygen valve the decomposition vessel is
self-sealing.
Replacing C 5010 sealing ring
In order to raise the sealing ring (item 13) the circlip (item 11) has to first
be pried out of the groove in the cover.
This is performed using a medium-sized slotted screwdriver, the flat
side of which is pressed between the circlip and the cover. When the
screwdriver is properly positioned the circlip is removed by pushing back
the cover edge.
Now the compression ring (item 12) and the sealing ring (item 13) may
be lifted.
Pos. 11 circlip
Pos. 12 compression ring
Pos. 13 sealing ring
When joining the individual parts make certain that the chamfers of the
compression ring and sealing ring point toward the side of the cover (see
diagram).
Mounted components:
The circlip (item 11) has to
snap exactly into the cover
groove. There is hardly any
play between the circlip and
the compression ring after
assembly.
The circlip may not be put
into the upper groove of the
cover groove because the
decomposition vessel would
not be tight.
