1 Important 1.1 General The information in this Service Manual is based on the Servo-u/Servo-n Ventilator System of System version 4.0. Unless otherwise stated, the Service Manual is valid also for System versions below 4.0. Maquet Critical Care AB, part of Getinge, is the legal manufacturer of the Servo Ventilator Systems. Service documentation for the Servo-u/Servo-n Ventilator System consists of:
Responsibility for the safe functioning of the equipment reverts to the owner or user in all cases in which service or repair has been done by a non-professional or by persons who are not employed by or authorized by Getinge, and when the equipment is used for other than its intended purpose. The system complies with standards and requirements as stated in the User's Manual. WARNING! Do not modify this equipment without authorization of the manufacturer.

Service Manual • bullet Installation Instructions • bullet Spare parts information • bullet Documentation for optional equipment included in • bullet the system. Product End-of-Life - Disassembly Instructions • bullet (Disassembly and Disposal Instructions) The Servo-u/Servo-n Ventilator System is referred to as 'the system' in this document.
System version and System software version The System version number can be found in the SYSTEM STATUS window on the User interface. Make sure that the version of the User’s Manual corresponds to the System version. The System SW version number can be found in the SYSTEM STATUS window on the User interface. For functionality enhancement, the latest released System SW version is always recommended. Serial number There are two serial number labels on the unit:
The User's Manual for the Servo-u/Servo-n Ventilator System is referred to as 'the User's Manual' in this document. Maquet Headquarter Support Center is referred to as ‘MCC HSC’ in this document. Note that MCC HSC is available only for the Getinge service organization. For other service organizations, for example hospital biomedical departments, technical support is provided by the local Getinge representative.
One label is attached to the Patient unit. The serial • bullet number stated on this label is the ID number of the Patient unit. The serial number is also stored in the software memory as the 'System ID'. One label is attached to the rear side of the User • bullet interface. The serial number stated on this label is the ID number of the User interface.

2.4.1 General
The main function of the Breathing subsystem is the patient treatment, that is, how to regulate and measure the inspiratory and expiratory gas flow:
The System software contains all available system functionality. The software is distributed across the subsystems. The installation procedure ensures that all subsystems are properly updated. The System software contains the following main subsystems: Breathing BRE • bullet Monitoring MON • bullet Panel PAN • bullet Power POW • bullet System ID • bullet Edi • bullet Y sensor • bullet
Controls all ventilation modes, ventilator settings • bullet and delivery of gas mixtures. Controls the expiratory cassette handling including • bullet flow measurement performed by the flowmeter in the cassette. Nebulizer control. Controls the Nebulizer function. • bullet Controls Pre-use check operations on the Breathing • bullet subsystem Maintain a persistent data storage area used to • bullet save parameter settings. Controls some of the system settings, such as, • bullet storing default patient category and mode of ventilation. The system settings are stored in persistent memory. The Breathing software is stored on PC 1991 Control and PC 2004/PC 2024 Expiratory Channel. The System software must be re-installed if PC 1991 or PC 2004/PC 2024 is replaced.
