9. Cleaning
Instrument will only function safely if cleaned regularly. Be sure to
clean instrument:
1. Immediately, if the hand wheels move stiffly
2. Before changing reagents
3. Before longer breaks in use
4. Before any maintenance and repair work
5. Daily after use with solutions prone to crystallization and concen-
trated bases
Warning:
The intake mechanism, valves, and intake/discharge tubes are
filled with reagent. Observe general safety regulations, e. g.,
wear protective clothing, goggles and gloves.
9.1. Emptying
1. Place instrument into a suitable basin.
2. Unscrew the instrument and lift it high enough so that the intake
tube is no longer immersed in liquid.
3. Cautiously tap the intake tube against the inside of the bottle so
that the reagent runs out.
4. Remove the instrument from the bottle and mount it on another
empty bottle.
Point the discharge tube into the opening of the used bottle, and
empty the instrument by turning the hand wheels. Then set the
valve switch to "recirculation" and turn the hand wheels again to
empty the recirculation channel.
9.2. Standard cleaning
1. Mount the instrument on a bottle filled with a suitable cleaning
solution.
2. Rinse the instrument thoroughly by turning the hand wheels.
3. Remove the instrument from the bottle and empty it completely
by turning the hand wheels, as described above.
4. Mount the instrument on a bottle filled with distilled water. Rinse
thoroughly, then empty, as described above.
