MAINTENANCE
The RUSH FOOT EVAQ8 Collection components may need periodic cleaning or replacement during the life cycle of the
system and are not replaceable under the warranty as it is considered normal wear:
Tubing (4)
Inline filter (5)
One-way valves housed inside the vacuum heel
Periodic Inspection of the system:
Visually inspect the tubing (4) for kinks, cracks, or wear that may leak air into the system. Replace tubing if any of
these conditions exist.
Remove the inline filter (5) from the tubing and hold up to a light to look through it. If light can be seen through it, the
filter is clean. If light is blocked, blast air from a syringe through the inline filter (5) from distal to proximal end (reverse
of normal flow) to attempt to clear the blockage. If blockage persists, the filter needs to be replaced.
If the amount of vacuum pulled by the system decreases, the one-way valves contained in the vacuum heel may
occasionally need to be cleaned and flushed with distilled water or isopropyl alcohol to ensure proper function. This
procedure should be done only by a qualified professional.
To flush the one-way valves and vacuum heel:
1. Disconnect tubing from distal end of the inline filter.
2. Remove the exhaust filter (3) and take care to not lose the one-way valve. The one-way valve may be inside
the bottom of the exhaust filter, or may stay inside the vacuum heel until step 4 of this procedure which should
dislodge the one-way valve from the housing.
3. Place tubing still connected to heel in cup of distilled water or isopropyl alcohol, or connect syringe filled with
distilled water or isopropyl alcohol to tubing.
4. Slowly cycle the vacuum pump by gently compressing the heel to draw the distilled water or isopropyl alcohol into
the system and cycle the water or alcohol through the heel and out the hole where the exhaust filter is installed.
5. Once the distilled water or isopropyl alcohol exiting the heel is clear or 5-10 heel compressions have been
performed (whichever is longer) remove the tubing from the water or alcohol source. Cycle the heel a few
more times to push any remaining water or alcohol out of the heel. It may be beneficial to invert the foot and
allow gravity to aid in removing the last bit of liquid out of the system.
6. Remove the one-way valve from the exhaust filter (3) or retrieve the dislodged one-way valve from the exhaust
side of the vacuum heel. Flush the one-way valve with distilled water or isopropyl alcohol using a syringe or
with compressed air.
7. Rinse the exhaust filter (3) with distilled water or isopropyl alcohol.
8. Reinstall the one-way valve into the exhaust filter (3) as shown in Figure 1.
9. Reinstall the exhaust filter (3) into the vacuum heel and torque to 14 in-lbs.
10. Reconnect the tubing (4) to the inline filter (5) and socket.
If the preceding procedure hasn't resolved the decreased vacuum pull, the one-way
valves and tubing should be replaced.
