3. Draw the disinfectant solution through the
pressure gauge tube into the syringe until the
latter is full. Do not flush through the pressure
gauge tube in the opposite direction!
4. Detach the syringe from the pressure gauge
tube and empty it out completely.
5. Repeat the procedure 5 more times.
6. After disinfection, the pressure gauge tube must
be rinsed with distilled water at least 8 times
using the same principle.
You can support the subsequent drying process with
medical compressed air or medical oxygen.
Then allow the component to dry thoroughly. If any
water is left in the pressure gauge tube of the venti-
lation tube, the device may not function correctly!

Masks, hoses and all rubber components should be

1. Make sure all internal and external surfaces are
thoroughly wetted and free from bubbles. Wait
for the full disinfection time to elapse.
2. After disinfection always rinse the components
inside and outside thoroughly with distilled wa-
ter to prevent any adverse effects from disinfect-
ant residues.
3. Always let the rubber components dry out in the
air.
4. Carry out a visual check of the masks and hoses
and replace any damaged components.
