1. Cleaning the Check Valve, vacuum inlet
Disconnect the check valve and connect a syringe to the proximal
tube with the flow direction arrow pointing away from the syringe.
If the valve is working correctly the syringe should only push
inwards. If the valve is blocked use the syringe to clear the valve
with a 'blast of air' (Do not use compressed air). If it is still blocked
clean it with distilled water using the syringe. If the valve is still not
working replace it (409663 or 409863).
2. Cleaning the Check Valve, exhaust port
Check the exhaust valve is working correctly by connecting a
syringe to the distal tube and clamp the proximal tube. Use a
'blast of air' to clear it through (Do not use compressed air). If
the exhaust valve is working correctly and retaining the vacuum
it should not be possible to draw the syringe plunger back out
again.
The valve should be silent after the user takes some
steps. Check that the seal is not compromised, clean
it or replace it if required.
Ensure the tubes are firmly connected and are not
kinked or split, replace if required.
Fully plantar flex and dorsiflex
the foot several times.
If the vacuum is working and
there is no vacuum at the
socket, the In-line Filter or
the Check Valve may need
replacing.
