Check Valve Cleaning
Check valve cleaning is applicable only the original beathing system model (P/N 0997-00-
0618) only. It does not need to be performed on the revised beathing system model (P/N
115-005967-00) (see FIGURE 6-1).
Constant contact with moist patient gas can result in the breathing system check valve
becoming sticky. Cleaning the check valve will resolve this issue. Perform this cleaning
procedure at least every 12 months.
NOTE:
Plastic gloves should be worn when handling breathing
systems
