13.11.2 Assembling the breathing system
►
Risk of insufficient anesthetic gas concentration
If the component connections of the breathing system are not sufficiently leak-
tight, ambient air may get into the breathing gas.
► Make sure that all components of the breathing system are connected tightly.
Assemble the breathing system in accordance with the instructions in this
chapter.
13.11.2.1 Inserting the non-return valves
The non-return valves (yellow inspiratory valve and blue expiratory valve) must be
fitted on the top side of the lower part of the breathing system.
There are recesses in the valve cages of the non-return valves to facilitate correct
fitting. These recesses are arranged differently on the inspiratory valve than on the
expiratory valve.
Perform the following steps for the non-return valves:
1. Align the inspiratory valve (1) and the expiratory valve (2) so that the
recesses (3) on the valve cages align with the corresponding lugs on the lower
part of the breathing system.
2. Insert the non-return valves.
