Cleaning Sample Tract (Intake Hose and Sample Chamber)
With all Aquacell Sampler models, in the interests of minimising sample contamination
the Sample Tract (Intake Hose and Sample Chamber) should be kept clean. The method
adopted to clean the sample tract will depend on how sensitive the application is to cross
contamination
Most parts of the sample tract are easily accessible and can be cleaned with a detergent
and / or a cream cleaner such as ‘CIF’ using a suitable brush
Inaccessible parts of the sample tract are usually flushed out with clean water. Where the
Sampler has to be completely free from the contamination of previous sampling
operations then replacement of inaccessible parts is the only option
The frequency of cleaning will depend very much on the application. Operational
experience with the Aquacell Sampler will enable you to decide how frequently the sample
tract should be cleaned in order to ensure that reliable and representative samples are
always collected
The parts of the sample tract which need to be kept clean are as follows:

Intake Hose assembly – Loosen hose clamp to remove. Either flush out with clean
water or replace

Sample Chamber / Chamber Top
When cleaning the Sample Chamber Top it is important to ensure that the inside
surface, particularly between the electrode pins, is kept free of wastewater
contamination. Wastewater deposits can form a conductive path between the
electrode pins which may lead to the occurrence of CLEAN CHAMBER TOP and / or
GUARD PROBE HIT faults. A test for conductive build-up on the Sample Chamber
Top is detailed in the ‘Test Mode’ later in this section
a) To clean the Sample Chamber Top firstly remove the Sample Chamber
assembly as detailed in ‘Removing / Refitting the Sample Chamber’ earlier in
this section
b) Clean the Sample Chamber with a cleaning sponge using a detergent solution
followed by a clean water rinse. Stubborn deposits may require a more
aggressive cleaner
