8.3.23 Check Viton Tubes and Replace if Necessary
The Viton tubes are black and are located on the gas cooler.
1. If the visual inspection results in a lining or blockage inside the tube, it must be cleaned or
replaced.
2. Clean the hose with deionised water and a pipe cleaner in a laboratory flask. If the hose is too dirty,
it should be replaced.
3. Remove the hose from both sides of the device and insert a new, identical Viton tube. This allows
the hoses to be replaced one after the other.
