Cold Disinfecting
1. Remove the outlet adapter and the exhalation valve assembly from the demand valve
assembly as described above. Clean the outlet adapter and the exhalation valve
assembly using a disinfecting solution approved by your facility. (Refer to
Manufacturer’s Recommendations). Do not allow any solution inside the demand valve
subassembly.
2. Remove the outlet adapter and the exhalation valve assembly from the solution and
rinse thoroughly with sterile water. Rinse repeatedly to be sure that all of the solution is
removed from the parts.
3. Check the exhalation valve assembly to be sure the flapper valve is not twisted.
WARNING:
If the flapper is twisted or not properly positioned, the demand valve will not
function properly. Make sure that the flapper valve lies flat against its seat.
4. Reassemble the parts
Maintenance:
Replacement Parts:
Outlet Adapter Housing, Exhalation Valve Assembly, Sintered Stainless
Steel Filter
Recommended Overhaul Period:
The demand valve should be overhauled annually. Contact Porter for details.
WARNING:
Do not disassemble or tamper with the main demand valve subassembly.
This will void the warranty. Improper disassembly or improper assembly procedures
may alter the performance of the valve which could cause serious injury to the patient.
In case of malfunction, return the demand valve to Porter immediately.
