16. PREVENTIVE MAINTENANCE
16.1 OVERVIEW
This section describes routine maintenance required for proper
care of the Instrument. Maintenance shall be performed only by
Baxter-certified service personnel. As each maintenance
procedure is completed, record the date, the serial number, and
Instrument hours in a log such as the one found at the end of this
section.
Before any adjustments or calibrations are made, the Instrument
should be allowed to warm up for at least 10 minutes.
When the annual maintenance is completed, perform a full
functional verification (see Section 19) of the system. Ensure that
the Instrument has been disinfected (see Section 9) before
returning it to clinical use.
WARNING
Before attempting to perform any repair, calibration, or
replacement in the hydraulic and pneumatic systems,
you must first run a complete disinfection cycle to
minimize the risk of contamination. The use of gloves
and eye protection is required.
A disinfect cycle must also be run after replacing any
parts in the hydraulics circuit.
