Maintenance & Service 6-13
6.5 Auto Maintenance Flush
If the HM5 has been powered on but not used for 4 days, it will perform an
Auto Maintenance routine to flush itself out to prevent salt build-up within
its internal tubing. If the notification appears, select
OK
to begin mainte-
nance immediately. Otherwise, the flush begins automatically within 2
minutes.
6.6 Peristaltic Pump Tubing Replacement
The analyzer’s peristaltic pump is designed to be maintenance-free. However, after long periods of
non-use, the pump tubing can become flattened and eventually needs to be “massaged” back into
shape, or replaced. A spare tube is included in the accessories kit.
Although replacement is a simple process, Abaxis strongly recommends contacting Abaxis Technical
Support before beginning. They will verify the need for pump tube replacement, and provide guidance
through the process if necessary.
Replace the peristaltic pump tube assembly as follows.
1. Open the analyzer’s back door, and locate the peristaltic pump at
the lower left of the rear compartment.
2. Disconnect the green and white color-coded tubes attached to the
base of the pump housing, by twisting the luer connectors as
shown.
Note: Wear latex or nitrile gloves during this procedure.
