The sampler must be kept clean of dirt on the following
points:
* The sampler glass must be kept clean on the inside
* The level electrodes in the top of the sample glass must
be cleaned
* The sample tube and the outlet tube must be cleaned
How often the cleaning is necessary, depends on how often
the sampler is used. In municipal sewage plant, we
recommend monthly cleansing, where the sampler tube is
put in a bucket with 10% diluted hydrochloric acid.
Hydrochloric acid is a degreaser and cleans grease and
sludge from all inside surfaes.
Start the sampler 2-5 times dependent on how much
coating there is on the inside surfaces.
The plastic house inside between the electrodes should be
cleaned.
The outlet tube should be removed during cleaning.
