Introduction ..3. Description of Disassembling and Service procedures ..6. Preventive Ventilator SystemImportant1 - 4 Service ManualRevision 02 General Service documentation for the Servo-i VentilatorSystem consists of: User's Manual . The User's Manual is anindispensable complement to the ServiceManual for proper servicing. Service Manual Installation Instructions spare Parts information. Documentation for all optional equipmentincluded in the Servo-i System is also available. The Servo-i Ventilator System is referred to asthe Servo-i troughout this Manual . There are two serial number labels on the unit: One label is attached to the Patient Unit closeto the supply gas inlets.

2 The serial numberstated on this label is the ID number of thePatient Unit. The serial number is also stored inthe SW memory as the ' System ID'. One label is attached to the rear side of theUser Interface close to the On/Off switch. Theserial number stated on this label is the IDnumber of the User Interface. System version number can be found in theStatus window on the User Interface. Make surethat the version of the User's manualcorresponds to the System inside a box is used to highlight importantinformation. In addition to the Important information givenhere and in the related documents (e. g. in theUser's Manual ), always pay attention toapplicable local and national regulations. Responsibility for the safe functioning of theequipment reverts to the owner or user in allcases in which Service or repair has been doneby a non-professional or by persons who are notemployed by or authorized by Maquet, and whenthe equipment is used for other than its notices Before disassembling or assembling of theServo-i, make sure that the: On/Off switch is set to Off.

3 Mains power cable is disconnected. Gas supply is disconnected (wall and/orcylinder). Battery modules are disconnected. The Servo-i is cleaned according toinstructions in the User's Manual , chapter'Routine cleaning' and chapter 'Regularmaintenance', section 'Extended cleaning ofinspiratory channel'. With power supply connected to the Servo-i ,there are energized electrical components insidethe unit. All personnel must exercise extremecaution if fault tracing or adjustments areperformed with power supply connected andwith user interface and patient unit used in this Manual ESD sensitive components. Whenhandling ESD-sensitive devices,established procedures must beobserved to prevent damage. Special waste. Discard disposable,replaced and left-over parts inaccordance with appropriateindustrial and environmentalstandards. Recycling. Recycle if facilities may not beavailable in all areas.

We reserve the right to modify products withoutamending this document or advising the user. Only personnel trained and authorizedby Maquet shall be permitted toperform installation, Service ormaintenance of the Maquet genuine spare parts mustbe used. PC boards ( spare parts) must always bekept in a package for sensitive electronicdevices. Maquet will not otherwise assumeresponsibility for the materials used, the workperformed or any possible consequences ofsame. The device complies to standards andrequirements as stated in the ' Servo-i VentilatorSystem User's Manual '.

5 Installation Only personnel trained and authorizedby Maquet shall be permitted to installthe Servo-i . The installation andhanding over procedures are describedin the ' Servo-i Ventilator System Installation Instructions'.Functional check After any installation, maintenance or serviceintervention in the Servo-i , perform a 'Pre-usecheck' according to instructions in the 'Servo-iVentilator System User's Manual '. Service The Servo-i must be serviced at regularintervals by personnel trained andauthorized by maintenance or Service must benoted in a log book provided. It is recommended that maintenanceand Service is done as a part of aservice contract with Maquet. Preventive maintenance must be performed atleast once every year as long as the unit is notused more than normal. Normal operation isestimated to correspond to approx. hoursof operation. Details are found in this ServiceManual, chapter Preventive maintenance.

6 The Battery modules shall be replaced everythree years. The internal Lithium batteries (on PC 1771 andPC 1772) shall be replaced every five years. Worn-out batteries must be recycled ordisposed of properly according to localregulations. Recycle facilities may notbe available in all areas. Batteries must not be disposed of withordinary waste. Discard all otherdisposable, replaced and left-over partsin accordance with appropriateindustrial and environmental standards. When working with ESD sensitivecomponents, always use a groundedwrist band and a grounded worksurface.
