WARNING
Great care must be taken. Do not damage the precision
surface of the valve seat (4).
Never use any hard object or abrasive agent to clean it;
use only a soft cloth.
If the valve seat is damaged, the diaphragm valve will
leak and may cause serious malfunction.
5. Clean the valve seat (4) , and the metal disk (5)
attached to the base of the diaphragm valve,
thoroughly and remove all contamination from the
surfaces of both components.
NOTE
If excessive contamination is discovered, check that
a bacterial filter is used in the expiratory limb of the
breathing circuit (and an HME at the patient tee-piece).
6. After cleaning, check that the small O-ring (6) located
in the bellows base under the diaphragm valve is in
place.
The ventilator will not function if the O-ring is
missing.
