PERIODIC INSPECTION OF THE EVAQ8 SYSTEM
Visually inspect the tubing for kinks, cracks, or wear that may leak air into the system. Replace tubing if any of these
•
conditions exist.
Remove the inline filter from tubing and look through it. If light can be seen, the filter is clean. If light is blocked, push air
•
from a syringe through the inline filter from distal to proximal end (reverse of normal flow) to attempt to clear the
blockage. If blockage persists, the filter needs to be replaced.
The one-way valves contained in the vacuum heel may need to be cleaned and flushed with distilled water or isopropyl
•
alcohol to ensure proper function. This procedure should only be done by a qualified professional.
1. Valve Body Assembly
To flush the one-way valves and vacuum pump:
•
Disconnect the vacuum hose from the socket barb and remove the EVAQ8 foot from the user's socket.
•
Place the socket end of the vacuum hose into isopropyl alcohol or distilled water and slowly cycle the vacuum pump
•
by compressing the heel of the foot with a T-bar or similar until the liquid can be seen coming out of (2) Exhaust
Filter.
After a few cycles of fluid flowing through the system, remove the hose from the isopropyl alcohol or distilled water
•
and cycle the pump slowly until no more fluid is exiting through the exhaust filter.
Reconnect the pump and vacuum hose.
•
To service and clean, or replace the components:
•
Remove the vacuum hose from the user's socket keeping it attached to the EVAQ8 foot.
•
Remove the EVAQ8 foot from the user's socket.
•
Remove the vacuum hose from the EVAQ8 foot.
•
Remove (1) Valve Body Assembly from the rubber pump by pulling on it, while rocking side to side.

Using a

Carefully tap the end of (1) Valve Body Assembly against your hand or on a table to allow (3) Spacer and (4) Duckbill
•
Valve (exhaust) to slide out and allow removal from (1) Valve Body Assembly.
NOTE: (4) Duckbill Valve (exhaust) will likely be pressed into the bottom of (3) Spacer.

Using a
⁄
" deep socket, remove (7) Straight Barb from the other side of (1) Valve Body Assembly.
•

Inside (1) Valve Body Assembly beneath where the (7) Straight Barb was located is another (6) Duckbill Valve (intake).
•
Remove (6) Duckbill Valve (intake) by tapping (1) Valve Body Assembly against your hand or on a table, or by
straightening out a paperclip and inserting it into the other side of (5) Valve Body to push out (6) Duckbill Valve
(intake).
Clean the female threads in both sides of (5) Valve Body with a cotton swab and isopropyl alcohol or distilled water.
•
If you are reusing (2) Exhaust Filter, (7) Straight Barb, in-line filter, and (4) and (6) Duckbill Valves, clean them with
•
isopropyl alcohol or distilled water. Take extra care and make sure (4) and (6) Duckbill Valves are clean and free from
debris (a magnifier is helpful for inspection). Flush the in-line filter from both directions to ensure it is clean. Allow
valves to air-dry. DO NOT use a towel or cloth.
Once the parts are dry, or if you are using new parts from a rebuild kit, set all the parts out on a clean surface.
•
Insert (4) Duckbill Valve (exhaust) into the end of (3) Spacer so that (4) Duckbill Valve (exhaust) rim is flush against
•
the opening of (3) Spacer and the tip of (4) Duckbill Valve (exhaust) is inside (3) Spacer.
Slide (3) Spacer into the longer side of (5) Valve Body with (4) Duckbill Valve (exhaust) toward the inside. Thread (2)
•
Exhaust Filter into (5) Valve Body BY HAND until snug. Torque to 15 in-lbs. Do not over torque. Over torquing will
snap the threads and will not be covered under warranty.
NOTE: If you do not have a torque wrench, thread (2) Exhaust Filter until you feel a hard stop and then turn
revolution more.
Insert (6) Duckbill Valve (intake) into the short side of (5) Valve Body so the tip of (6) Duckbill Valve (intake) points
•
into (5) Valve Body. Using a small screwdriver or a straightened-out paperclip, make sure (6) Duckbill Valve (intake)
is seated all the way into the recess.
BY HAND, thread (7) Straight Barb into the short side of (5) Valve Body.
•
Once the (7) Straight Barb is threaded in snugly BY HAND, torque it to 15 in-lbf. This is a very low torque value, and
