The Centiva/5 Plus CC Ventilator is equipped with an expiration valve locking  
mechanism that uses a motor driven locking system to properly fix the expiration 

valve inside the system. To repair and inspect expiration valve: 

 

1.

 

Remove the expiration valve according to section 7.2.1. 

2.

 

Remove membrane plate (1) to gain access to the PEEP membrane 

assembly (2). 

3.

 

Remove the PEEP membrane assembly (2) from the base of valve (3) and 

replace membrane, if necessary.  

4.

 

In case the PEEP membrane assembly (2) is apart, lock the PEEP membrane 

assembly together by inserting the silicon lock at the PEEP top seal 

membrane (2a) through the PEEP PSU plate (2b) (cut edge facing 2c) and 

then through the PEEP silicone membrane (2c). Pull on the lock until the 

locking lip is fully engaged.  

5.

 

Insert the PEEP membrane assembly into the expiration valve with the 

sealing membrane (2c) facing down. The side of the top seal (2a) marked 

“top” should be facing the top.  

6.

 

Inspect and clean flow measurement port. 

7.

 

Replace and grease o-ring (5) at flow measurement port. 

8.

 

Use the inspiration connection nut of service tools to remove the flow screen 

retainer (8) by turning counterclockwise.  

9.

 

Carefully remove the flow screen (7) and o-ring (6).  

10.

 

Insert o-ring (8) and the flow screen (7). 

11.

 

Use the inspiration connection nut of service tools to fix the flow screen 

retainer (8) by turning clockwise.  

12.

 

Verify proper function after reassembly by performing a system test.
