HOW TO USE THIS MANUAL
products/material in need of factory repair shall be sent to:
The manual is divided into several sections. The DIAGNOSTICS section describes self-test
and service diagnostics for checking the system functions. An understanding of the on-board
service capabilities is necessary before any attempt is made to troubleshoot the unit. The
TROUBLESHOOTING section lists error codes and provides troubleshooting guides to
assist the Technical Service Representative in locating the source of a problem. The
REPLACEMENT PROCEDURES section contains instructions for removal and replacement
of assemblies that are considered field-replaceable. The ADJUSTMENT AND
CALIBRATION PROCEDURES section contains the field procedures needed to restore
original system specifications. The Periodic Manufacturer’s Service (PMS) PROCEDURE
section outlines the steps required to verify the electrical, mechanical and pneumatic safety
of the unit and also identifies components requiring periodic replacement.
GENERAL TROUBLESHOOTING GUIDELINES
Troubleshooting the Narkomed 6000 should always begin by communicating with those who
observed or experienced a problem with the unit. This may eliminate unnecessary
troubleshooting steps. Once a general problem is identified, refer to the troubleshooting flow
charts in Section 3 to determine the proper corrective action to be taken.
After any component is replaced, verify that the unit is operating properly by running the
appropriate diagnostic procedure. The PMS PROCEDURE in Section 6 must also be
performed after any component is replaced.
The general arrangement of the Narkomed 6000 anesthesia system is shown on the opposite
page.
