To get a reliable result the system must run without moving any valves and the mini-
mess hose should not touch the bottle.
Only ¾ of the bottle shall be filled because the laboratory has to shake the sample
to get a mixed fluid when they analyse it. Minimum 200 ml are needed for a good
analysis.
When the bottle is filled close the cap as soon as possible to prevent contamination
from the air to enter the bottle and give wrong result.

1. Clean the area around the air filter breather. See Fig. 2: Main components DOb
