General
Symbols used in this manual
• Service documentation for the Servo-i Ventilator System consists of:
• ESD sensitive components. When handling ESD-sensitive devices, established procedures must be observed to prevent damage.
– User's manual. The User's manual is an indispensable complement to the Service Manual for proper servicing.
• Special waste. Discard disposable, replaced and left-over parts in accordance with appropriate industrial and environmental standards.
– Service Manual – Installation Instructions – Spare Parts information. – Documentation for all optional equipment included in the Servo-i System is also available. • The Servo-i Ventilator System is referred to as the Servo-i troughout this manual.
• Recycling. Recycle if possible. Recycling facilities may not be available in all areas.
• There are two serial number labels on the unit: – One label is attached to the Patient Unit close to the supply gas inlets. The serial number stated on this label is the ID number of the Patient Unit. The serial number is also stored in the SW memory as the 'System ID'. – One label is attached to the rear side of the User Interface close to the On/Off switch. The serial number stated on this label is the ID number of the User Interface. • System version number can be found in the Status window on the User Interface. Make sure that the version of the User's manual corresponds to the System version.
• Technical training. Refers to the Technical training supplied by Maquet. • Service contract. Refers to the Service contract supplied by Maquet.
Hazard notices • Before disassembling or assembling of the Servo-i, make sure that the: – On/Off switch is set to Off.
Text inside a box is used to highlight important information. • In addition to the Important information given here and in the related documents (e. g. in the User's manual), always pay attention to applicable local and national regulations. • 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 Maquet, and when the equipment is used for other than its intended purpose.

Important Installation
To the responsible service personnel
• Only personnel trained and authorized by Maquet shall be permitted to install the Servo-i. The installation and handing over procedures are described in the 'Servo-i Ventilator System – Installation Instructions'.
• The contents of this document are not binding. If any significant difference is found between the product and this document, please contact Maquet for further information. • We reserve the right to modify products without amending this document or advising the user.
Functional check • After any installation, maintenance or service intervention in the Servo-i, perform a 'Pre-use check' according to instructions in the 'Servo-i Ventilator System – User's manual'.
Service • The Servo-i must be serviced at regular intervals by personnel trained and authorized by Maquet. Any maintenance or service must be noted in a log book provided.
• Only personnel trained and authorized by Maquet shall be permitted to perform installation, service or maintenance of the Servo-i. Only Maquet genuine spare parts must be used. PC boards (spare parts) must always be kept in a package for sensitive electronic devices. Maquet will not otherwise assume responsibility for the materials used, the work performed or any possible consequences of same. • The device complies to standards and requirements as stated in the 'Servo-i Ventilator System – User's manual'.
• It is recommended that maintenance and service is done as a part of a service contract with Maquet. • Preventive maintenance must be performed at least once every year as long as the unit is not used more than normal. Normal operation is estimated to correspond to approx. 5.000 hours of operation. Details are found in this Service Manual, chapter ”Preventive maintenance”. • The Battery modules shall be replaced every three years. • The internal Lithium batteries (on PC 1771 and PC 1772) shall be replaced every five years. • Worn-out batteries must be recycled or disposed of properly according to local regulations. Recycle facilities may not be available in all areas. • Batteries must not be disposed of with ordinary waste. Discard all other disposable, replaced and left-over parts in accordance with appropriate industrial and environmental standards. • When working with ESD sensitive components, always use a grounded wrist band and a grounded work surface. Adequate service tools must always be used.
