Servicing Lower Cylinders
This test is only possible with the our TyrFil Flushless Manifold. If you are using the original
Flushless Manifold or you are uncertain which style you are using, contact the Accella Tire Fill
Systems Technical Center or your technical representative before performing this test.
1. Reduce the regulator setting to 40 psi (3 bar). Open the ball valves on the “ISO” and
“CAT” totes.
2. Turn on the ball valve at the air motor.
3. This test will dispense several pounds of material. Make sure your waste container
can handle this volume.
4. Over a waste container, position the body of the Flushless Manifold so that you can
observe the material streams flowing into the waste container. Slowly open the hand
valve and observe the material streams for several cycles. The material streams
should be even on both the “ISO” and “CAT” sides as the pump cycles up and down.
If one side is absent, note which direction the pump is moving (either up or down) and
which side is absent. EXAMPLE: On the down stroke, “ISO” side has no stream. On
the up stroke, both “ISO” and “CAT” have a stream.
5. Repeat step 4 to verify your results.
6. Refer to the chart below for analysis.
