Safety instructions
For your protection
Read the operating instructions in full before st-
arting up and follow the safety instructions.
•
Keep the operating instructions in a place where they can be
accessed by everyone.
•
Ensure that only trained staff work with the appliance.
•
Follow the safety instructions, guidelines, occupational health
and safety and accident prevention regulations.
Work with the device
DANGER
Before use, check the outlet pres-
sure on the pressure reducer and
compare it with the pressure dis-
played on the pressure gauge.
Oxygen as a compressed gas is
oxidising; intensively aids combus-
tion; can react violently with flam-
mable materials.
•
The filling time should not be set to less than 30 seconds.
This will prevent combustible substances from being whirled
around in the crucible.
•
Insufficient ventilation can cause formation of explosive mix-
tures. Therefore, only use the device in well-ventilated areas.
•
Check the seals for damage before each use.
•
After finishing work, the oxygen supply on the pressure redu-
cer must be closed.
For protection of the device
DANGER
Maintenance tasks should be per-
formed without any excess pres-
sure on the system.
The Valve needle (29) is held in
place with safety varnish to keep it
from being turned unintentionally.
It should only be removed if there
iv no excess pressure on the sys-
tem
•
Keep lines and fittings through which oxygen flows free of
grease.

composition vessels C 7010, C 7012 and AOD 1.1 with oxygen.

Operating instruction
Description of the device
•
The 2 m pressure hose, included with delivery, can easily be
laid to connect to the oxygen bottle.
•
Therefore, the location of the C 48 filling station does not
depend on the oxygen bottle being in the immediate vicinity.
•
The filling pressure that is set and the pressure in the decom-
position vessel can be read directly from the work station,
thus preventing insufficient filling quantities because of not
observing the minimum filling period.
•
The filling time can be adjusted in increments.
•
There is no need to bee constantly occupied with the oxygen
bottle because the automatic non-return valve only opens if a
decomposition vessel is being filled.
•
A carrier plate (screws on left-handed or right-handed) is
used to prepare samples.
Installation
Connecting the pressure hose
The pressure hose (43), included with delivery, is designed for a
maximum pressure of 40 bar. It is 2 m long and easily be laid to
connect to the oxygen bottle (smallest permissible bending radius
80 mm).
There is an R1/4inch threading
(SW 17) on the C 29 reducing
valve (accessory) of the oxygen
bottle to which the other end of
the pressure hose can be connec-
ted.
An appropriate adapter is inclu-
ded for US pressure reducers.
Decomposition vessels
IKA
decomposition vessels C 1/8; C 7010, C 7011, C 7012 and
AOD 1.1 are provided with an identification on the base or on the
cap screw that contains information including the year of manu-
facturing number.
Assembly of the support plate
The support plate, included with
delivery, can be screwed on right
or left. The cover of the decom-
position vessel can be set down
on the support plate. This makes
it easer to load cecomposition
vessels.
C 29
It should be connected at point
“
A (SW 10)“.
Longer plastic lines are available
on request.

Commissioning
The required filling pressure -usually
30 bar -can be set on the pressure
reducer valve of the oxygen bottle.
The adjusted pressure can also be
read on the pressure gauge (11).
The automatic non-return valve (33)
integrated into the oxygen filling sta-
tion prevents oxygen from flowing
out when this is not intended.
When the task is complete. the
main valve on the oxygen supply
should be closed.
The decomposition vessel should be
placed on the holding plate (38 or
50). By loosening the screw (3), the
holding plate (38 or 50) can be ad-
justed so that the filling head (32) fits
exactly onto the oxygen line valve of
the decomposition vessel.
All you need to do then to fill up the
decomposition vessel is to swing the
hand lever downwards. The increase
in pressure can be observed on the
pressure gauge.

The factory-set filling time can be
changed by turning on the valve
needle (29). Turning the safety valve
counter-clockwise results in a longer
filling time.
The filling time should not be less than 30 seconds. This
will prevent combustible substances from being whiled
around in the crucible.
The valve needle (29) is held in place with safety varnish
to keep it from being turned unintentionally. It should only
turned if there is no excess pressure on the system.
