Installing the apparatus
- We recommend to install the apparatus as close to the sampling point as possible.
- The hose has to be laid with a constant fall from the sampler to the sampling point as lower
lying points can lead to deposits in the hose which may freeze in winter or result in cross-
contaminations.
- To fix the suction hose, we recommend to use the extraction unit available as accessory.
- Immerse the end of the hose at the sampling point with the open end facing downstream
(direction of flow) so that coarse matter and fibres cannot be forced into the suction aperture
