Grease the centering tube and housing as follows:
1 Grease the sliding surfaces on the upper side of the centering tube
with paraffin grease 6.2803.010.
2 Grease the sliding surfaces on the interior edge of the housing with
paraffin grease 6.2803.010.
3.2 Mounting the storage vessel and the holder
The dosing unit comes equipped with a storage vessel 6.2008.030 with
holder 6.2008.050 for the storage of the buret tip. It should be mounted
when the device is started up for the first time.
The storage vessel serves as a storage container for the buret tip when the
dosing unit is not in use.
The associated holder is used at the same time for mounting a name plate
with the designation of the reagent in the dosing unit. Name plates can
be reordered under the order number 6.2244.020 from any Metrohm
agent.
The dosing unit housing must be removed in order to assemble the stor-
age vessel holder (see "Removing the housing", page 10).
