First Steps
3.
Mounting the
filling tube and
recirculation tube
Adjust the length of the telescoping fill-
ing tube to the bottle height and attach
it. Insert the recirculation tube with the
opening pointing outward (Fig. 3).
Wear protective clothing, eye protection and gloves! Follow all safety
instructions and observe limitations of use and operating limitations
(see page 37).
Attention:
4.
Mounting and
aligning the instru-
ment on a bottle
Screw the instrument (GL 45 thread)
onto the reagent bottle and then align
the titrating tube with the bottle label.
For bottles with other thread sizes, select
a suitable adapter. The titrating tube can
be adjusted by 70 mm both horizontally
and vertically (Fig. 4).
The adapters supplied with the instru-
ment are made of polypropylene (PP),
and can only be used for media which do
not attack PP (see 'Accessories',
page 62).
5.
Transporting
the instrument
When mounted to a reagent bottle,
always carry the instrument as shown
in the figure (Fig. 5)!
Note:
Do not rotate the hand wheels when the valve is set to 'Titrate'
and the titrating tube is closed with the screw cap.
Avoid splashing the reagent! The reagent can drip out from the
titrating tube and screw cap.
Warning!
Initializing (cont.)

With readily crystallizing media, e.g.
alcoholic KOH, the length of the tele-
scoping filling tube should be adjusted
to a distance of approx. 20 mm from the
bottom of the bottle.
