Operating manual
Before using the product, please read this operating manual carefully and keep it ready to hand,
when required.

General information

This TÜV accredited soot pump stands out because of
its high fabrication quality and design.
These features are guarantying a durable and reliable
functioning.

Field of application

The soot pump serves for determining the smoke spot
number of oil burning installations (diesel soot).

Basic safety instructions

!!! Measure appropriate !!!
Before using the soot pump, warm it up to room
temperature.
After approx. 10 measurements, check the
withdrawal probe up to the valve for soot deposit and
clean it. In regular intervals, this also applies for the
other parts of the flue-gas pump (Maintenance of the
pump).
Occasionally test the soot pump for leaks (see:
Testing the pump for leaks). It is recommended to keep
the soot picture comparison scale always in its wrapper
and thus clean.
!!! Ensure warranties!!!
It is precondition, that the soot pump is exclusively
used appropriate and according to the intended use.
Do not apply force to the testing instrument.
(It may not defend against it!)

Test operation

Sampling of soot
Before taking the soot sample, the burner should
Already be in operation for at least 5 minutes.
A Insert the filter paper in the
slot opening on the pump head
and clamp it with a clockwise
rotation of the probe head.
B Bring the probe tube
through the measuring vent of the
exhaust pipe in the middle of the
flue-gas flow.
C Perform 10 full suction strokes;
draw slowly and uniformly (suction stroke), shortly
pause at the stop (pressure equalisation), than move
back fast. According to the prescription, 1.63 +/-
0.07dm3 exhaust gas are thereby drawn through the
filter paper.
The operation time of the 10 strokes has to be 40-60
seconds.
D Release the probe head with a left-hand rotation
and extract the filter paper stripe. A measuring spot
with the corresponding colouring remains on the filter
paper.
For being able to determine the smoke spot number of
a fireplace, at least 3 samples have to be taken! The
smoke spot number than is averaged out of them (see:
Determination of the smoke spot number).
In case of a sluggish operation of the pump, lubricate
the piston packing
(see: Lubrication of the soot pump)!
Test for oil derivates
A Test the measuring spot for oil-derivates. For that
purpose, drop some solvent system acetone close to
the measuring spot. If there is no grey coloration, no oil
is contained.The sample is correct.
Otherwise
If there is a grey coloration of the measuring spot: The
exhaust gas contains oil! Inspect the oil burning
installation! (acetone is not part of the set)
B Hold the filter paper
with the measuring spot
behind the grey scales of the
soot picture comparison
scale until the spot appears
fully in centre and read off
the smoke spot number. The
shade of grey most looking
similar to the measuring
spot density shows the
smoke spot number.
C Now average over the smoke spot numbers of all
samples withdrawn.
This value, round up to the next whole number, is the
value respectively the smoke spot number of the
installation.
