8.2 Condensation on the cuvette
INFORMATION! The drying system can only remove residual
moisture but cannot remove large droplets of water.
The drying system prevents moisture from forming inside the
device due to condensation. To ensure proper operation, the desic‐
cant and the seals must be kept in a good condition. Replace these
components if they are deformed or worn.
Condensate may form on the cuvette if the flow unit with meas‐
uring cuvette is removed from the device. The introduction of addi‐
tional moisture into the device is not recommended as this conden‐
sate will shorten the life of the desiccant. For this reason, wipe all
condensate from the cuvette before reinstalling the flow unit.
Proceed as follows if condensate is forming on the cuvette:
1.
Block the flow using the ratchet clamp supplied.
2.
Drain the water from the cuvette to reduce the cold mass.
3.
Pour clean warm water into the cuvette if it is available.
4.
Dry and clean the outside of the cuvette.
5.
Make sure that the cuvette is firmly inserted into the flow unit.
6.
Refit the flow unit.
7.
Restart the flow of sample water.
As soon as the flow unit has been inserted into the device, the
drying system prevents the formation of further condensate inside
the device, regardless of the external environment or the tempera‐
ture of the sample water.
All seals are important for proper operation and for extending the
life of the desiccant. These seals need to be fitted and maintained.
Replace all faulty, deformed or worn seals. Contact Technical Sup‐
port.
Check the following seals regularly:
n
The red seal that seals the measuring cuvette (included in the
sealing kit, order number 1116184)
n
The dark grey seal under the flow unit (included in the sealing
kit, order number 1116184)
n
The orange-coloured circular housing seal (order number
1116185)
n
The cover of the USB connector.
