The inspection of the metrological reliability including maintenance work is offered as a service
(including a manufacturer's certificate, if so ordered). In this case the titration device is to be sent in.
Please contact the service (see backside of this manual).
Detailed description of the inspection and maintenance work:
[1] Wipe off using a soft cloth (and some water with a normal household detergent).
[2] Leaking connections can be identified by moisture or crystals at the threaded connections of
the hoses, at the sealing lips of the piston inside the dosing cylinder or at the valve.
[3] If any liquid becomes visible below the first sealing lip, it has to be checked at short timely
intervals whether any liquid will build up under the second sealing lip, too. In this case both the
piston and the glass cylinder have to be replaced immediately. It is easily possible that in
operation small liquid droplets build up under the first sealing lip, but they may also disappear
again. This phenomenon alone is no reason for replacement.
[4] The valve has to be removed from its housing for inspection. In this process, the hoses remain
connected to the valve. Please check for moisture underneath the valve. When reinserting the
valve, please make sure that the small cam at the rotating axis is fitted into the corresponding
groove again.
[5] The titration tip must be free of sedimentation or crystals which might obstruct the dosing
process or falsify the results.
[6] Remove the cylinder, take the valve out of the valve housing, unscrew the hoses and then
rinse all parts carefully with distilled water. For the assembly of the cylinder, hoses and other
parts of the interchangeable unit, please refer to the operating instructions.
[7] Dose one burette volume, then refill. Air bubbles will gather at the tip of the cylinder and in the
titration hose where they can be detected easily. If bubbles become visible, please re-tighten
all connections finger tight, and then repeat dosing. If air bubbles still remain within the
system, [6] please check the valve and replace the hose connections. The air bubbles may
also occur at the interface between the sealing lip of the piston and the cylinder. If a reduction
of the filling speed will not do, the dosing unit has to be replaced.
[8] Check the electrical plug contacts for corrosion and mechanical damage. Defective parts have
to be repaired or replaced by new parts.
[9] Please refer to the application „Burette inspection according to ISO 8655 Part 6".

9 Storage and transportation

If the titrator TitroLine® 5000 or the interchangeable units have to be stored over some time, or to be
dislocated, the use of the original packing will be the best protection of the devices. However, in many
cases this packing will not be available anymore, so that one will have to compose an equivalent
packaging system. Sealing the lower section in a foil is hereby recommended.
The devices should be stored in a room with a temperature between +10 and +40°C, and the (relative)
humidity of the air should not exceed 70 %.
If the interchangeable have to be stored over some time, or to be dislocated, the fluids inside the
system, especially aggressive solution have to be removed (please refer also to chapter 8.
„Maintenance and Care of the burette").

10 Recycling and Disposal

Please observe the applicable local or national regulations concerning the disposal of "waste
electrical and electronic equipment".
The present titrator and his packaging are manufactured as far as possible from materials which can
be disposed of environmental-friendly and recycled in a technically appropriate manner.
If you have any question regarding disposal, please contact the service (see backside of this manual).
The main printed board carries a lithium battery. Batteries should not to be disposed of with the
normal domestic waste. They will be taken back and recycled or disposed of properly by the
manufacturer at no cost.
