6.3 General Troubleshooting Guide
The following is a list of potential issues and methods of resolution. The suggestions for each issue
are listed from most to least probable. Therefore, each step assumes the previous steps have been
checked. For component replacement instructions, see Chapter 7.
Note that this guide assumes that no special equipment, such as the Medivance Calibration Test Unit
is available. If available, the Calibration Test Unit is a powerful diagnostic tool and it should be used
in association with the instruction in its manual.

Alarms and Alerts
The pads have been filled,
then purged and then refilled. Trapped air bubbles
may restrict flow
temporarily. Allow the flow to stabilize for over
20 minutes before rechecking the
flow rate. Air can be removed by
lightly tapping on the pads.
The pad connectors are not
fully seated in the fluid
delivery line manifolds. Air leak in fluid delivery
line manifold
connection. Reseat connectors.
Pad lines are kinked or
occluded at either the
connector and pad ends. Restriction in fluid lines Remove kinks. Recommend use
of fluid delivery line straps to keep
lines from kinking.
Look for pad leaks by
inspecting for a continuous
stream of bubbles in the tubes
exiting the pads when no air
is entering. Leak in pad. Replace pad.
Enter Stop Mode, then hold
manifold above Control
Module and pads, pad
connector side up. Air fills the
connectors. Leak at seal between
pad connector and the
fluid delivery line
manifold. Air may be
entering the return side
of the fluid delivery line
and is not visible in the
pad lines. Reseat the connector. If leak
continues, replace fluid delivery
line.
Pads connected.
Low water flow or air
continuously streaming
from pads. The pump can
be heard.
Disconnect each pad in turn
from the manifold to
determine whether one pad is
contributing to the low flow.
Try to prevent air from
entering the lines when
removing the pads and run
long enough to assure
stability before checking the
flow. One pad is not
functioning properly.
There is an air leak in
the manifold.
Replace pad.
Replace fluid delivery line.
